Explanation:

In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.

Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.

STP conditions are defined as a pressure of

100 kPa

and a temperature of 0∘C

. Under these conditions for pressure and temperature, one mole of any ideal gas occupies

22.7 L

- this is known as the molar volume of a gas at STP.

So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.

The balanced chemical equation for this decomposition reaction looks like this

Answer:

Products

Explanation:

Reactants → Products

Chemical reactions are characterized by the formation of new products, and the making and breaking off strong chemical bonds.

Answer: They are the PRODUCTS of the reaction.

Explanation: In a chemical reaction, there are the REACTANTS and the PRODUCTS.

The reactants are the "ingredients" in the chemical formula. They are what are being chemically combined in a way.

The products are the "meal," or what the reactants combined to create.

For example, when creating salt or NaCl, this is essentially the formula:

In this formula, Na (sodium) and Cl (chlorine) are the reactants. NaCl (sodium chloride, aka salt) is the product.

I hope this clears things up, and I hope this was the context in which the question was asked!

Volume of Glucose solution = 144 mL  OR 0.144 L

Molarity of Glucose solution = 0.280 M

From the definition of Molarity, we know that:

Molarity = number of moles / volume(in L)

in this equation, multiplying both sides by Volume, we get:

number of moles = Molarity*Volume(in L)

replacing the variables

Number of moles = 0.280*(0.144L)

Number of moles = 0.04

We know that:

Number of molecules = Number of Moles * Avogadro's number

Number of molecules = 0.04 * 6.022 * 10²³

Number of molecules = 0.24088 * 10²³

Number of molecules = 2.4088 * 10²²

Therefore, there are 2.4088 * 10²² molecules of Glucose in the given solution

Answer:

Mass percentage does not have any unit as numerator and denominator contains the same unit. The percent by mass of Ca in CaCl[tex]_2[/tex] is equal to (40/111) x 100. The correct option is option A.

Mass percentage represents the the percentage of each element that is making a particular compound.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

Atomic weight of different element of calcium chloride{ CaCl[tex]_2[/tex]} are

Ca = 40 ; Cl = 35

Total mass of Calcium element in calcium chloride = 40g/mol

Total mass of Chlorine atom in calcium chloride = 35× 2= 71g/mol

Total molar mass of calcium phosphate = 40 +71= 111g/mole

Percentage of calcium in calcium chloride =40÷111 = 36%

Therefore, the percent by mass of Ca in CaCl2 is equal to (40/111) x 100. The correct option is option A.

Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.

The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous solutions of lithium phosphate and magnesium nitrate are mixed.

2 Li₃PO₄(aq) + 3 Mg(NO₃)₂(aq) ⇒ 6 LiNO₃(aq) + Mg₃(PO₄)₂(s)

The complete ionic equation includes all the ions and insoluble species.

6 Li⁺(aq) + 2 PO₄³⁻(aq) + 3 Mg²⁺(aq) + 6 NO₃⁻(aq) ⇒ 6 Li⁺(aq) + 6 NO₃⁻(aq) + Mg₃(PO₄)₂(s)

The net ionic equation includes only the ions that participate in the reaction and insoluble species.

2 PO₄³⁻(aq) + 3 Mg²⁺(aq) ⇒ Mg₃(PO₄)₂(s)

Answer:

ΔH3 = -110.5 kJ.

Explanation:

Hello!

In this case, by using the Hess Law, we can manipulate the given equation to obtain the combustion of C to CO as shown below:

C(s) + 1/2O2(g) --> CO(g)

Thus, by letting the first reaction to be unchanged:

C(s) + O2(g)--> CO2 (g) ; ΔH1 = -393.5 kJ

And the second one inverted:

CO2(g) --> CO(g) + 1/2O2(g) ; ΔH2= 283.0kJ

If we add them, we obtain:

C(s) + O2(g) + CO2(g) --> CO(g) + CO2 (g) + 1/2O2(g)

Whereas CO2 can be cancelled out and O2 subtracted:

C(s) + 1/2O2(g)  --> CO(g)

Therefore, the required enthalpy of reaction is:

ΔH3 = -393.5 kJ + 283.0kJ

ΔH3 = -110.5 kJ

Answer:

The ion is d^10

Explanation:

Tetrahedral geometry is one in which the central atom/ion is located at the center of four ligands positioned at the corners of a tetrahedron.

It is different from a square planar complex wherein the ligands are positioned at the corners of a square with the central atom/ion at the center of the square.

Tetrahedral complexes are more common with d^10 species.The electronic configuration of Cu I is [Ar]3d104s1. Hence, a tetrahedral geometry is preferred over a square planar geometry.

The number of Bromine combining magnesium

Explanation:

The subscript gives the number of atom/s combining to form a compound. For this problem, 1 atom of Mg combines with 2 atoms of Br.

To form the ionic combine, Mg will lose two electrons. A bromine atom requires just one electron to have a complete octet. So, two bromine atoms will be needed to complete the bonding process.

Therefore, Mg loses two electrons to two Br atoms and the electrostatic attraction from the charges created forms the ionic bond.

The number 2 represents the number of bromine atoms.

Magnesium bromide is formed by the combination of magnesium (metal) and bromine (non-metal).

The valency of magnesium is 2 while that of bromine is 1. To form a neutral compound 2 moles of bromine ion combines with 1 mole of magesium ion.

Thus, the number 2 represents the number of bromine atoms.
