please help woth calculations with #3,4,5. thank you!
Data: Original mass of candle: 30.81 Mass after 5 minutes of combustion: 369 Mass of candle lost to combustion: 0:16 Calculations: A typical wax used for making candles is paraffin wax, which has the molecular formula CisHs2. With this information, answer the following questions using the data you recorded for your candle. Show your work! 1. What is the molar mass of candle wax, CzHsz? 25(12.011) +52(1.008)= 352.69 g/mol 2. How many...

I need help with part B
Explanation:
A mole ratio is the ratio between the amounts in moles of any
two compounds involved in a chemical reaction. The mole ratio can
be determined by examining the coefficients in front of formulas in
a balanced chemical equation.
Step 1: write the balanced chemical
equation.
Sb2S3(s) + 3Fe(s)→2Sb(s) +3FeS(s)
Step 2: calculate the moles of
Sb2S3 , Fe
Moles of Fe = mass given / molar mass = ( 25 g
/...

Objective Find the ratio of moles of reactant to moles of a product for the reaction below. Compare mass and mole amounts of reactants to determine the amount of products that can be/are made. Background Chemical reactions are represented by balanced chemical equations. Proper interpretation of an equation provides a great deal of information about the reaction it represents and about the substances involved in the reaction. For example, the coefficients in a balanced equation indicate the number of moles...

Next you convert grams to moles using the molar mass of the starting material in this case coal. I'm going to change the number up slightly so that I don't give away the answers but the final answer we get will be close to the correct answer to the original question. The formula for coal is C135H96O9NS. On anxam that formula will be given to you. Calculate the molar mass from the formula and use the molar mass as a...
