Left side: H = 2 ; O = 2 (number based on the subscript)

Right side: H = 2 ; O = 1 (number based on the subscripts; no subscript means that the element is just 1)

Notice that the number of H is already balance but the number of O is not. In order to balance the O, you need to multiply the element by 2, but you CANNOT do this by simply changing the subscript.

Hence,

Left side: H = 2 ; O = 2

Right side: H = 2 x 2 = 4 ; O = 1 x 2 = 2

Now, notice that the number of O is now balance (both are 2) but the number of H is not (since

is a substance and not an element, you need to multiply everything by 2). So, what to do?

You also multiply the left side H by 2. Hence,

Choose the options below that are true of standard reduction potential. (select all that apply) Select all that apply: All standard reduction potentials are measured against that of the reduction of hydrogen ions to H2 gas. The standard reduction potential of a cell is determined by subtracting the standard reduction for the reaction at the anode from the standard reduction potential for the reaction at the cathode. Standard reduction potentials are dependent on reaction stoichiometry. The standard reduction potential for a cell is determined by adding the standard reduction potential for the reaction at the anode to the standard reduction potential for the reaction at the cathode.

Answers

Answer:

All standard reduction potentials are measured against that of the reduction of hydrogen ions to H2 gas.

Explanation:

The standard hydrogen electrode (SHE) serves as a sort of reference electrode. All standard electrode potentials of chemical systems are measured against the standard hydrogen electrode whose electrode potential has been arbitrarily set at 0.00 V.

The reduction potential of any other system is measured against the standard hydrogen electrode by connecting that half cell to the standard hydrogen electrode and observing the reading of the voltmeter. The standard hydrogen electrode consists of hydrogen ions of unit activity, hydrogen gas at 1 atm and the system is maintained at a temperature of 298 K.

Standard reduction potentials are measured against that of the reduction of hydrogen ions to [tex]H_2[/tex] gas because hydrogen is chosen as a standard reference and has electrode potential zero.

It is impossible to measure absolute electrode potential for an electrode without forming cell . Therefore it is assumed that standard electrode potential for hydrogen is zero

The standard reduction potential of a cell is determined by subtracting the standard reduction for the reaction at the anode from the standard reduction potential for the reaction at the cathode.

                        [tex]E_c_e_l_l[/tex]°[tex]= E_c_a_t_h_o_d_e[/tex]°[tex]- E_a_n_o_d_e[/tex]°

The species liking to get reduced is defined in term of standard reduction potential.

The species whose standard reduction potential is to be calculated is placed at cathode and at anode hydrogen electrode is used.

What does an increase in temperature do to the reaction rate?

Answers

Answer:

An increase in temperature typically increases the rate of reaction because an increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.

Explanation:

A gas is contained in a horizontal cylinder with a moveable piston of cross-sectional area 0.33\text{ m}^20.33 m 2 . The region outside the cylinder is at standard ambient temperature and pressure, 298\text{ K}298 K and 1\text{ bar}1 bar. When 2040\text{ J}2040 J of heat flow into the gas, the internal energy of the gas increases by 1380\text{ J}1380 J. Calculate the distance through which the piston moves. You may assume friction is negligible.

Answers

Answer:

0.02 m

Explanation:

∆U = q + w

w = ∆U - q = (1380 - 2040) J = -660 J

w = -p∆V = -pA∆h

∆h = -w/(pA)

p = 1 bar × (100000 Pa/1 bar) = 100000 Pa

∆h = -(-660 J)/(100000 Pa×0.33 m²) = 0.02 m

A gas is contained in a horizontal cylinder with a moveable piston of cross-sectional area 0.33\text{ m}^20.33 m 2. The distance through which the piston moves is 0.02 m.

What is piston ?

Among other related systems, pistons are found in reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders, and pneumatic cylinders. It is the moving part that is enclosed in a cylinder and sealed off from the gas by piston rings.

The piston, which is a part of combustion engines, transforms the energy released during combustion into a mechanical action and sends it, via the piston pin and connecting rod, to the crankshaft as a torsional force. The piston in the cylinder goes up and down when the engine is running.

The equation given by

∆ U = q + w

w = ∆ U - q

= ( 1380 - 2040 )

J = -660 J

w = -p∆V

= -pA∆h

∆h = -w / (pA)

p = 1 bar × ( 100000 Pa / 1 bar )

= 100000 Pa

∆h = - ( -660 J) / ( 100000 Pa × 0.33 m² )

= 0.02 m

Thus, The distance through which the piston moves is 0.02 m.

If this block has a mass of 173.7 grams, then what is this element??

Answers

Answer:

C

I am pretty sure that is the answer

The mass of the given cube of 173.7g and the volume of the box is 9 cm³.Then the density is 19.3 g/cm³. Therefore, the element with this density is gold. Option D is correct.

What is density?

Density of a substance is the ratio of mass to its volume. Thus it tells about how much denser the substance is in the given volume. This physical quantity is dependant on mass, volume temperature and pressure.

The element have their own density corresponding to the mass and volume used. The dimensions of the given box is 3, 3 and 1. Thus volume is the product of this length, breadth and height.

Volume = 3 ×3 × 1

             = 9 cm³.

Mass of the box is given 173.7 grams. Now, the density of the element is calculated as follows:

Density = 173.3 /  9 cm³

             = 19.3 g/cm³.

From the table, it is clear that the this density corresponds to the element gold. Therefore, option D is correct.

Compare the purple and orange arrows. Does more energy go into breaking bonds, or is more energy released when new bonds form?

Answers

Answer:

The breaking of chemical bonds never releases energy to the external environment. Energy is only released when chemical bonds are formed. In general, a chemical reaction involves two steps: 1) the original chemical bonds between the atoms are broken, and 2) new bonds are formed. These two steps are sometimes lumped into one event for simplicity, but they are really two separate events. For instance, when you burn methane (natural gas) in your stove, the methane is reacting with oxygen to form carbon dioxide and water. Chemists often write this as:

A 10 M concentrated stock solution of NaCl is used to prepare 2 liters of diluted 1 M
solution. Which of the following is true for the process used to achieve the required
dilution? (5 points)
O The volume of the solvent used is less than 0.1 liters.
O The volume of stock solution used is less than 0.1 liters.
The volume of stock solution used is more than 2 liters.
The volume of the solvent used is less than 2 liters.

Answers

Answer: It is true for the process used to achieve the required dilution that volume of the solvent used is less than 2 liters.

Explanation:

Given: [tex]M_{1}[/tex] = 10 M,       [tex]V_{1}[/tex] = ?

[tex]M_{2}[/tex] = 1 M,       [tex]V_{2}[/tex] = 2 L

The volume of stock solution is calculated as follows.

[tex]M_{1}V_{1} = M_{2}V_{2}\\10 M \times V_{1} = 1 M \times 2\\V_{1} = 0.2 L[/tex]

A solution which contains small amount of solute is called a dilute solution. Whereas a solution which contains more amount of solute is called a concentrated solution.

The stock solution is used for dilution and hence, it acts as a solvent. Its calculated volume is 0.2 L.

This means that volume of the solvent used is less than 2 liters.

Thus, we can conclude that it is true for the process used to achieve the required dilution that volume of the solvent used is less than 2 liters.

Answer: The volume of the solvent used is less than 2 liters.

If you have 2 water molecules together, would you expect them to sit "hydrogen by hydrogen" or "hydrogen to oxygen"? Why?

Answers

Answer:

"hydrogen to oxygen"

Explanation:

Hydrogen bonds are formed when hydrogen is bonded to highly electronegative element such as Chlorine, fluorine, oxygen etc.

In hydrogen bonding, the hydrogen atom of one molecule of water is attracted to the oxygen atom of another molecule of water via permanent dipole-dipole interaction.

Hence, If you have 2 water molecules together, they always sit "hydrogen to oxygen" as a result of dipole - dipole interaction and  hydrogen bonding between water molecules.
