Answer:
48.075g(or 48g in correct sig figs)***
Explanation:
=48.075g
*64.1g is the mass of SO2 which is calculated by simply taking the mass of sulfur and oxygen(but doubling it since there are two oxygens) and adding them together(32.1+2x16.0)
**btw the mol units cancel because of dimensional analysis in case anyone was wondering why
***if your teacher is like mine and specifically wants your answer in correct sig figs, use the answer in parentheses as the original problem only has 2 sig figs
Answer:
C. H₂SO₄
Explanation:
Given expression:
H₂O + SO₃ → H₂SO₄
In the chemical reaction, the product and the reactant have the same species.
Chemical reactions obeys the law of conservation of matter.
This way, atoms combine with one another to give a desired product. The products will contain a mix of the reactants.
- Fluorine is not part of the reactants
- Carbon is not part of the reactants
- Carbon is not part of the reactants.
Answer:
Explanation:
Our 
sample yielded 1g of 
and 16g of 
, but our unknown sample yielded 2 times as much for the same amount of .
What does this mean? that the H:O proportion for the unknown sample is twice the H:O proportion for the sample.
What is the H:O proportion for the sample? As we can see from its formula, it's 1:1, therefore the proportion for the unknown formula must be 2:1.
That means, two H atoms for every O atom. We could write that as: 
and you should recognize that formula, for it is one of the most common compounds on earth, Water.
Answer:
32(molecular mass has no unit )
Explanation:
(16)(o2)
16×2
=32
there are 92 naturally occuring elements
