Here are my reasonable beliefs
For number 1. what the answer seems to be is C.Than looking are numbers two and three their answers are both B
My reasoning for them is , because if you think about the solid liquid gas's this is a common result in most experiments.also for number two , you have to decrease ( go down ) on the concentration ( hardness ) of the subject to get a more powerful solution
So far as number one , for it to be water the atoms have to be far away from the other moving freely , to be a solid they can barely move at all.
Answer:
The answer to your question is 4.14 g of O₃
Explanation:
Data
mass of nitrogen dioxide = 3.97 g
mass of ozone = x g
Reaction
NO₂ (g) + O₂ (g) ⇒ NO (g) + O₃ (g)
- Check that that reaction is balanced
Reactants Elements Products
1 N 1
4 O 4
This reaction is balanced
- Calculate the molecular mass of NO₂ and O₃
NO₂ = 14 + 32 = 46 g
O₃ = 48 g
- Calculate the mass of Ozone formed.
46 g of NO₂ ------------------ 48 g of O₃
3.97 gof NO₂ ---------------- x
x = (3.97 x 48 ) / 46
x = 190.56 / 46
x = 4.14 g of O₃
... and a power ot ten.
For example: 1,3x10^21 is in scientific notation, but 13x10^20 is not in scientific notation.
The first part of the answer is in the photo attached. I hope i can attach a second photo...
