Try d cuz if im not mistaken if you burnt white phosphorus all the gas is going to take most the air
Here are some disadvantages, is that nitrogen dioxide is a toxic gas and it can still be harmful when ingested by human, also critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions.
Hope this helps
Answer:
The concentration of this sodiumhydroxide solutions is 0.50 M
Explanation:
Step 1: Data given
Mass of sodium hydroxide (NaOh) = 8.0 grams
Molar mass of sodium hydroxide = 40.0 g/mol
Volume water = 400 mL = 0.400 L
Step 2: Calculate moles NaOH
Moles NaOH = mass NaOH / molar mass NaOH
Moles NaOH = 8.0 grams / 40.0 g/mol
Moles NaOh = 0.20 moles
Step 3: Calculate concentration of the solution
Concentration solution = moles NaOH / volume water
Concentration solution = 0.20 moles / 0.400 L
Concentration solution = 0.50 M
The concentration of this sodiumhydroxide solutions is 0.50 M
The smallest mass among the choices is Choice (ii):2.3 x 10-3 μg
This is so because, the prefix μ signifies a factor of 10^-6.
For choice I:
- 23 cg means 23 centigrams
For choice II:
- 2.3 × 10-3 μg means 2.3 × 10-9 grams
For choice III:
- 0.23 mg means 0.23 × 10-3 grams
For choice IV:
- 0.23 grams simply means 0.23grams
For choice V:
- 2.3 × 10-2 kg means 23 grams
Ultimately, Choice II represents the smallest mass.

Glaciers capture large amount of carbon dioxide from atmosphere. When concentration of carbon dioxide molecules in glaciers increase, then strength and fracture toughness of ice are decreased and <span>that make glaciers vulnerable to cracking and splitting into fragments.
</span>That is because hydrogen bonds between water molecules in glaciers is decreased under increasing concentrations of carbon dioxide who <span>competes with the water molecules connected in the ice crystal.</span>
