Answer:
option A
Explanation:
Atomic number of Nitrogen (N) = 7
So, no. of protons and electrons = 7
Then,
In order to compute this, we must first take a couple of assumptions of:
1) The laboratory size so we can calculate its volume
2) The number of students working in the lab so we know the total gas produced
Let the lab be
11 m × 9 m × 6 m
The volume then computes to be:
594 m³
We know that
1 Liter is 1 dm³
1 m = 10 dm
1 m³ = 1000 dm³
Therefore, the room volume in liters is:
594,000 Liters
Let there be 30 students in the laboratory
Total gas being produced:
6 × 30
= 180 Liters
This works out to be:
0.03% of Hydrogen by volume
Therefore, there is no risk of explosion given our assumption of size and students.
The answer is B. There is no “because”.
I believe it’s
The reactants
The products

the gold would float because the gold is lighter then the silver. the silver is more haver then the gold. so the gold will float and silver will not float
