Consider the process in which HClO3 is converted to HClO2. The oxidation state of oxygen remains −2, and the oxidation state of
mixas84 [53]

Answer:

Option 1, Cl is reduced and gains electrons

Explanation:

HClO₃  → HClO₂

In HClO₃, chlorine acts with +5 in the oxidation state

In HClO₂,, chlorine acts with +3 in the oxidation state.

The state has been reducted, so the Cl has been reduced. As it was reduced, it means that has won e⁻, in this case 2

Cl⁻⁵  → Cl⁻³  +  2e⁻

Consider the following balanced reaction. How many grams of water are required to form 75.9 g of HNO3? Assume that there is exce
Iteru [2.4K]

Answer:

10.85 g of water

Explanation:

First we write the balanced chemical equation

3NO_{2} +H_{2}O -->2HNO_{3} +NO

Then we calculate the number of moles of nitric acid produced

n(HNO3) = \frac{mass}{molar mass} =\frac{75.9g}{63.02g/mol}=1.2044 mol

According to the balanced equation, water needed in moles is always half the number of moles of HNO3 produced. So since we will produce 1.2044 mol of HNO3, we will need 0.6022 mol of water. Now to calculate what mass that is:

mass(water)=number of moles*molar mass=0.6022mol*18.02g/mol=10.85g

If two identical atoms are bonded together, what kind of molecule is formed?
AlekseyPX

Answer:

C. A linear, nonpolar molecule

Explanation:

Molecules which are alike usually have the same degree of pull which results in them sharing electrons. This sharing of electrons is known as the molecules exhibiting Covalent bonding between them.

The equal pull also results in the cancelling out of electrons and favoring non polar bonds due to the absence of free electrons which would have been able to interact with H2O in a polar binding system.
