They all do. If you throw them off a building and watch them shatter.
Explanation:
Answer:
34 g of water, will be produced
Explanation:
The balanced equation for production of water with oxygen is:
2H₂ (g) + O₂ (g) → 2H₂O (l)
2 mol of hydrgen gas react with 1 mol of oxygen to produce 2 moles of water.
Let's determine the moles of O₂ (mass / molar mass)
30 g / 32g/mol = 0.9375 moles
Ratio is 1:2. So If I have x moles of oxygen I would produce the double of moles of water.
0.9375 moles . 2 = 1.875 moles
Let's convert the moles to mass ( mol . molar mass)
1.875 mol . 18g/mol = 33.75 g ≅ 34 g
Answer:
False
Explanation:
From what I know about water and gas, this is false
Answer:
option C is correct (250 g)
Explanation:
Given data:
Half life of carbon-14 = 5700 years
Total amount of sample = 1000 g
Sample left after 11,400 years = ?
Solution:
First of all we will calculate the number of half lives passes during 11,400 years.
Number of half lives = time elapsed/ half life
Number of half lives = 11,400 years/5700 years
Number of half lives = 2
Now we will calculate the amount left.
At time zero = 1000 g
At first half life = 1000 g/2 = 500 g
At second half life = 500 g/2 = 250 g
Thus, option C is correct.
