2C(s) + 2H2(g) + 52.4kJ ⇋ C2H4(g)

Chemistry
1 answer:
PtichkaEL [24]3 years ago
3 0

Answer:

A. The equilibrium will shift towards the right, towards the formation of products

B. The concentration of hydrogen gas will decrease as more of it is used in the formation of products

C. Increasing the temperature at which the reaction is performed will increase the concentration of C2H4, the product of the reaction.

Explanation:

The given reaction is an exothermic reaction as it requires the addition of extra energy of about 52.4KJ in the form of heat for the reaction to proceed towards product formation.

According to L' Chtler principle, when an external constraint is applied to A given system in equilibrium, equilibrium position will shift so as to annul the effect ofnthe constraint imposed on the system.

Therefore, the answers tonthe questions above are given below as follows :

A. The equilibrium will shift towards the right, towards the formation of products in order to remove the effect of the additional heat since the forward reaction is endothermic.

B. The concentration of hydrogen gas will decrease as more of it is used in the formation of products .

C. Increasing the temperature at which the reaction is performed will increase the concentration of C2H4, the product of the reaction as the equilibrium will shift towards the right; formation of products.

How is the oxidation state of a transition metal determined from the chemical formula ?
Vera_Pavlovna [14]

Answer:

Explanation:

In a chemical formula, the oxidation state of transition metals can be determined by establishing the relationships between the electrons gained and that which is lost by an atom.

We know that for compounds to be formed, atoms would either lose, gain or share electrons between one another.

The oxidation state is usually expressed using the oxidation number and it is a formal charge assigned to an atom which is present in a molecule or ion.

To ascertain the oxidation state, we have to comply with some rules:

  • The algebraic sum of all oxidation numbers of an atom in a neutral compound is zero.
  • The algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to  the charge on the ion.

For example, let us find the oxidation state of Cr in Cr₂O₇²⁻

This would be:  2x + 7(-2) = -2

                          x = +6

We see that the oxidation number of Cr, a transition metal in the given ion is +6.

If 1.27 moles of bromine gas (Br2) react with excess phosphorus (P), how many moles of phosphorus tribromide (PBr3) will be prod
frez [133]

Answer:

0.85 mole of PBr3.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3Br2 + 2P —> 2PBr3

From the balanced equation above,

3 moles of Br2 reacted to produce 2 moles of PBr3.

Therefore, 1.27 moles of Br2 will react to produce = (1.27 x 2)/ 3 = 0.85 mole of PBr3.

Therefore, 0.85 mole of PBr3 is produced by the reaction.

What is the density of an object with a mass of 16 g and 3.0 ml
fomenos

Answer:

D = 5.3 g/mL

Explanation:

Density = Mass over Volume

D = m/V

Step 1: Define

D = unknown

m = 16 g

v = 3.0 mL

Step 2: Substitute and Evaluate

D = 16 g / 3.0 mL

D = 5.333333333 g/mL

Step 3: Simplify

We have 2 sig figs.

5.333333333 g/mL ≈ 5.3 g/mL
