Answer:
mass of sulfur = 96 g
Explanation:
no of moles of sulfur dioxide in 
molecules = 
= 2 moles
therefore mass of sulfur dioxide = moles×atomic number
=2×(16+32)
=96
Answer:
D. The piece of bread travels with straight- line horizontal acceleration.
Explanation
Answer:
moles = given mass/atomic mass
so H2O mass = 2 +16=18
so 12g of h2o= 12/16 = 3/4 moles
A) Fe⁰ ----> Fe⁺³ +3e⁻ oxidation | *2
b) <u>Cu⁺² + 2e⁻ -----> Cu⁰ reduction |*3</u>
c) 2Fe⁰ +3Cu⁺² -----> 2Fe⁺³ + 2Cu⁰
