### How do you draw molecular compound structures? Example: C2H2

It's hard to describe how to draw these compounds. However, I will try my best using the example provided. The example provided would look like this H-C(triple bond)C-H. First it is important to know how many electrons you are working with. In this case there are ten electrons. 8 from carbon and 2 from hydrogen. After you know this, you can draw the structure. Each carbon atom needs an octet or eight atoms surrounding it. Creating a triple bond with the other carbon and a single bond with one hydrogen atom allows for this to happen. It takes practice to master drawing structures but with time it gets easier! I hope this helped!

### The atom is the basic unit in chemistry. An atom contains neutrons, protons, and electrons. Neutrons are neutral, protons have a positive charge, and electrons have a negative charge. Most of the time, atoms are neutrally charged, meaning that they have the same number of protons and electrons. Sometimes, though, atoms lose or gain one or more electrons, and become positively or negatively charged. A positively or negatively charged atom is called an ion. An ion with more protons than electrons is positively charged. An ion with more electrons than protons is negatively charged. One common ion is a Sodium ion, which has a charge of +1. Which of the following statements is true? The ion has more protons than electrons. The ion has the same number of protons and electrons. The ion has more electrons than protons.

The ion has more electrons than protons. For sure

### In the treatment of domestic water supplies, chlorine is added to the water to form chloric(I) acid,HClO. Cl2(aq) + H2O(I) → H+(aq) + Cl–(aq) + HClO(aq) The HClO reacts further to give the chlorate(I) ion.(CLO-) HClO(aq) + H2O(I) → H3O+(aq) + ClO–(aq) Both HClO and ClO–kill bacteria by oxidation. What is the change in oxidation number of chlorine in forming the chlorate(I) ion from the aqueous chlorine? PLEASE SHOW WORKING :)

Chlorine goes from Cl₂ to ClO⁻.

Oxidation state of Cl in Cl₂ is zero whereas in ClO⁻ it is +1. Hence change in oxidation state of Chlorine is 1.

Calculation of oxidation number of Cl in ClO⁻ or HClO⁻ :
Let x be oxidation number of Cl in ClO⁻ the. Now since the net charge on ClO⁻ is -1, sum of oxidation number of all must be equal to -1.

Therefore,
x + (-2) = -1 .....[ oxidation number of O is -2]
∴ x = 2-1 = +1
Therefore oxidation number of Cl in ClO⁻ is +1

### In a hydrogen fuel cell, hydrogen gas and oxygen gas are combined to form water. write the balanced chemical equation describing this reaction (using lowest whole-number coefficients.

Answer:

2H₂ + O₂ → 2H₂O

Explanation:

The problem tells us that hydrogen gas (H₂) and oxygen gas (O₂) are the reactants, while water (H₂O) is the only product. Thus, the reaction is:

H₂ + O₂ → H₂O

In order to balance this equation, we begin with counting the atoms of O present in the left side and in the right side of the equation. Because there are two O atoms in the left but only one on the right, we add a coefficient of 2 in the right side:

H₂ + O₂ → 2H₂O

Now we count the H atoms, there are 2 in the left and 4 in the right, so we add a coefficient of 2 for the hydrogen gas:

2H₂ + O₂ → 2H₂O

Now there are 4 H atoms in both sides, and 2 O atoms in both sides, so the equation is balanced.
