Methyl chloride

Well, 1st, you need to take the Fahrenheit temperature and subtract it from 32, make sure you put it in parentheses. Then, 2nd, you multiply it by it by 5/9. Here's an example of my explanation didn't make since:
T(°C) = (68°F - 32) × 5/9 = 20 °C
And that's how you convert Fahrenheit to Celsius temperatures.
Answer: iron (iii) oxide, Fe2O3.
Explanation: we must calculate the oxidation state of Fe in Fe2O3
Fe2O3 = 0
2Fe + 3(-2) = 0
2Fe — 6 = 0
2Fe = 6
Fe = 6 /2 = 3
So the oxidation state of Fe in Fe2O3 is +3
So the name of the compound is iron (iii) oxide
Answer:
A
Explanation:
The specific heat capacity can be defined as the amount of energy that is required to raise the temperature of 1kg of a body by exactly 1k.
When calculating the amount of heat required, we usually employ the use of the formula that relates the amount of heat, the mass of the body, the specific heat capacity and the temperature change. The amount of heat is represented by H, the mass of the body by m, the heat capacity by C while the temperature difference is represented by delta T
The physical state that best describes the scientist's sample is solid (option C).
<h3>What are the states of matter?</h3>
Matter refers to any substance that has mass and occupies space. The states of matter are as follows;
- Solids; a substance in the fundamental state of matter that retains its size and shape without need of a container.
- Gases; a matter in a state intermediate between liquid and plasma that can be contained only if it is fully surrounded by a solid
- Liquids; substance that is flowing such as water; Liquids readily change their relative position, and which therefore retains no definite shape, except that determined by the containing receptacle.
According to this question, a scientist observed a sample of an unknown material to have molecules that are packed closely together and have fixed positions in space relative to each other. It has resistance to deformation and change of volume.
This description best fits the solid state of matter.
