Answer:

Metallic bonding is found in metals and their alloys. When the atoms give up their valence electrons, they form ions. These ions are held together by the electron cloud surrounding them. Metals are shiny because they have a lot of free (i.e. delocalized) electrons that form a cloud of highly mobile negatively charged electrons on and beneath the smooth metal surface in the ideal case. ... In the absence of any external EM field, the charges in the plasma are uniformly distributed within the metal.

Explanation:

In metallic bonding, the electrons are “surrendered” to a common pool and become shared by all the atoms in the solid metal.

Double replacement :

2Na₃PO₄+3CaCl₂⇒6NaCl + Ca₃(PO₄)₂

1. A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds

2. Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product

3. Combination/syntesis : 2 or more reactants combine to form a new compound

4. Decomposition : the reactant is decomposed into 2/more products

If we look at the reaction options available, all of them can be included in the double replacement reaction, but we only choose the reaction from Sodium phosphate and Calcium chloride which leads to options: C because it is balanced (from the number of atoms in the same reactant and product) and is in accordance with the chemical formula of each compound (both products and reactants)

Answer:

Q = 66984.43 J

Explanation:

Given data:

Mass of water = 1.8 Kg (1.8Kg×1000 g/1 Kg =1800 g)

Initial temperature = 8.4°C

Final temperature = 17.3°C

Specific heat capacity of water = 4.1813 J/g.°C

Heat required = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 17.3°C - 8.4°C

ΔT = 8.9°C

Q = 1800 g ×  4.1813 J/g.°C ×8.9°C

Q = 66984.43 J

The correct answer is Hot water increases the collision rate of molecules, causing the reaction to occur faster.

Explanation:

Temperature is directly related to the kinetic energy or movement of molecules in a substance. In this context, a higher temperature leads to more kinetic energy or more collision between molecules. At the same time, a chemical reaction involves molecules of two or more substances colliding and creating bonds to form new substances. This implies an increase in temperature means molecules colliding faster, new substances forming in a shorter time, and therefore a faster chemical reaction. According to this, the first answer is correct.

Let us remember that energy is neither created nor destroyed but is transformed from one form to another. This is known as the principle of energy conservation. Hence energy in the universe never disappears!

The fan that is not spinning has potential energy. Potential energy is energy possessed by a body by virtue of its position. When the fan starts spinning, this potential energy is converted to kinetic energy.

Answer:

= 15.51 mL

Explanation:

Here's is the reaction:

2HgO(s) ⇒ 2 Hg(s)+O₂(g)

In this reaction 2mol HgO =  1mol O₂

The molecular weight of HgO = 216.59g

so, 3.0g HgO = 3.0g x 1.00molHgO/216.59gHgO

= 0.0138511 molHgO

The amount of Oxygen follows:

0.0138511 molHgOx1/2= 0.00692555 mol O₂

Now, volume of 1 any gas = 22400mL

so, 0.00692555 mol O₂ x22400mLO₂/1mol O₂

= 15.513232mL O₂

 Mass of CS₂  = 0.25 x 76 = 19g

Answer:

2.5%

Explanation:

Given

M1 = 7.50%

M2 = ?

V1 = 25.0mL

V2 = 75.00mL

M1V1=M2V2

7.5x25=M2x75

M2=2.5%

The NaCl of a solution made by diluting 25.0 ml of a 7.50 (m/v)% NaCl solution to a total volume of 75.00 ml is 2.5 (m/v)%.

Solution is defined as a continuous variation of two or more substances in their relative proportions up to what is known as the limit of solubility.  A solute is the name for the substance that dissolves to create a solution. A solvent is the material that a solute will dissolve in. Sugar is the solute and water is the solvent in a sugar-water solution.

To calculate the molarity of NaCl

We use M1V1 = M2V2

Given M1 = 7.50 (m/v)%

V1 = 25.0 ml

V2 = 75.0 ml

M2 = M1 V1 / V2

M2 = 7.50 x 25.0 / 75.0

M2 = 2.5 (m/v)%

Thus, the NaCl of a solution made by diluting 25.0 ml of a 7.50 (m/v)% NaCl solution to a total volume of 75.00 ml is 2.5 (m/v)%.

Answer:

17.09g/L

Explanation:

Density = total mass of elements/ volume

We need to find the mass of each mixture constituents using their molar mass:

mole = mass/molar mass

For Neon (Ne) which contains 0.650mol;

0.650 = mass/20.18

mass = 0.650 × 20.18

mass = 13.12g

For Krypton (Kr) which contains 0.321mol;

0.321 = mass/83.79

mass = 0.321 × 83.79

mass = 26.89g

For Xenon (Xe) which contains 0.190mol;

0.190 = mass/131.3

mass = 0.190 × 131.3

mass = 24.95g

Total mass = 13.12g + 26.89g + 24.95g = 64.96g

Density = total mass / volume

Density = 64.96g / 3.80L

Density of the mixture = 17.09g/L

Hello!

In this case, since the mass of iron (III) oxide is missing we use 80.0 g as found on similar problems. In such a way, since iron (III) molar mass is 159.70 g/mol, one mole of iron (III) oxide has two moles of iron (subscript) and one mole of atoms of iron have 6.022x10²³ atoms (Avogadro's number), the correct number of atoms in such sample is:

[tex]atoms \ Fe=80.0gFe_2O_3*\frac{1molFe_2O_3}{159.70gFe_2O_3}*\frac{2molFe}{1molFe_2O_3}*\frac{6.022x10^{23}atoms}{1molFe} \\\\atoms\ Fe=6.03x10^{24}atoms[/tex]

Answer:

It has 10 neutrons

Explanation:

Answer:

Partial pressure of neon = 175 mmHg

Partial pressure of xenon = 564 mmHg

Explanation:

The partial pressure of a gas in a mixture can be calculated as the product of the mole fraction of the gas (Xi) and the total pressure (Pt), as follows:

Pi = Xi Pt

The total pressure is 739 mmHg ⇒ Pt =  739 mmHg

In order to calculate the mole fraction of each gas, we have to first calculate the number of moles of each gas (n) by dividing the mass of the gas into the molar mass (MM):

For neon gas (Ne):

MM(Ne) = 20.18 g/mol

n(Ne)= mass/MM = 0.919 g x 1 mol/20.18 g = 0.045 mol Ne

For xenon gas (Xe):

MM(Xe) = 131.3 g/mol

n(Xe)= mass/MM = 19.1 g x 1 mol/131.3 g = 0.145 mol Xe

Now, we calculate the mole fraction (X) by dividing the number of moles of the gas into the total number of moles (nt):

nt= moles Ne + moles Xe = 0.045 mol + 0.145 mol = 0.190 mol

X(Ne) = moles Ne/nt = 0.045 mol/0.190 mol = 0.237

X(Xe) = moles Xe/nt = 0.145/0.190 mol = 0.763

Finally, we calculate the partial pressures of Ne and Xe as follows:

P(Ne) = X(Ne) x Pt = 0.237 x 739 mmHg = 175 mmHg

P(Xe) = X(Xe) x Pt = 0.763 x 739 mmHg = 564 mmHg

Answer:

512 K

Explanation:

Initial pressure P1 = 645 Torr

Initial Temperature T1 = 128 ºC + 273 = 401 K (Upon converting to kelvin temperature)

Final Pressure P2 = 824 Torr

Final Temperature T2 = ?

The relationship between the variables is given as;

P1 / T1  = P2 / T2

Making T2 subject if formula we have;

T2 = P2T1 / P1

Inserting the values we have;

T2 = 824 * 401 / 645 = 512 K
