The specific heat of gasoline is 2.22 J/g•°C. How much heat would it take to raise 35.0 G of gasoline to 3.00°C?
Olenka [21]
<span>To find the amount of heat energy required to raise a substance by a certain number of degrees, we simply multiply: (specific heat * change in temperature * mass) Heat = 2.22 * 35 * 3 = 233.1 joules Therefore, we would need 233.1 joules of heat to raise the temperature by 3 degrees Celsius.</span>

What are the parts of a calorimeter and the function of each part?
chubhunter [2.5K]

A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction occurs in solution in a calorimeter, the heat produced by the reaction is absorbed by the solution, which increases its temperature.

Write the formula unit equation for this reaction occuring in water:
larisa [96]

The formula unit equation for the given reaction occurring in water is

CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

<h3>What is chemical reaction?</h3>

Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.

When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:

CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)

Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.

Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
