Base your answers to questions 1 through 3 on the information below and on your
knowledge of chemistry.
Given the unbalanced equation showing the reactants and product of a reaction
occurring at 298 K and 100. kPa:
P4(s) + Cl2(g) → PC13(C) + energy
1. a. Show a numerical setup for calculating the percent composition by mass of chlorine in
PCl3(l) (gram-formula mass = 137 g/mol).

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

the answers would be

the first one and the second one

i think its 5049.

i hope this !

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
