Answer:
Explanation:
Hi there!
2Pb (no₃) -------> 2Pb + 4no₂ + o₂
Molecular mass of 4no₂ = 184g
Molecular mass of o₂ = 32g
From the reaction;
When 184 g of no₂ was formed 32 g of oxygen was formed.
When 1 g of no₂ was formed 32/184 g of oxygen was formed.
When 11.5 g of no₂ was formed (32/184)*11.5 g of oxygen was formed.
Therefore, when 11.5 g of no₂ was formed 2 g of oxygen was formed.
Hope it helps!
I’m doing so well and life is just life :) but what about u how has ur day been going
If he is 4 now is in 10 years he will be 14 and if you multiply that by 2 you get 28 which means in 10 years Marie will be 28 so that means if you take away 10 the answer should be 18 but that isn't there but that's how I would work it out.
<h2>Answer with Explanation </h2>
To discover average you include the scores from each subject and afterward separate them by what number of various numbers you have. An example is shown below, like if there were three subjects who got different scores. The next step would be to add the score of all subjects.
Example
- 1+2+3=6
After adding the total sum will be divided by the number of students.
- 6/3=2
When you have the midpoints of all subjects over the 4 years, the one that is most noteworthy will be answer.
