e. ice changed to gas
f.the specific heat of vaporisation is greater than heat of fusion because eventually all the ice changed to gas it becomes vaporisation
C
Everyday, ever hour and so on the weather changes, when looking at the weather on an app or website, the weather is defined by the conditions at a certain time. Hope this helps!
Answer:
4804.5 g of SO₂ are needed to the reaction
Explanation:
The reaction to produce sulfuric acid is:
2SO₂ + O₂ + 2H₂O → 2H₂SO₄
Ratio is 1:2. 1 mol of oxygen needs 2 moles of sulfur dioxide in order to react. We can propose this rule of three.
If 1 mol of O₂ react to 2 moles of SO₂
Then, 37.50 moles of O₂ will react with (37.5 . 2) /1 = 75 moles of SO₂
We convert the moles to mass, to know the answer:
75 mol . 64.06 g / 1 mol = 4804.5 g of SO₂
Mass = protons + neutrons
7+8 = 15 g
Answer: 5 days
Explanation:
1,000,000/2 = 500,000 *do this because of the 2 numbers every second
500,000/60= 8,333.33 *do this to get minutes
8,333.33/60= 138.88 *do this to get hours
138.88/24= 5.7866 *do this to get days
5 days 7 hours 8 minutes 6 seconds
