Answer:
b) Conduction, convection, and radiation
I assume there is a typo in the equation. It is H2O instead of H2I.
The ratio of H2 and O2 that react with each other is 2:1. To find out the grams of H2, we need to first find out the moles of O2 and H2.
Moles of O2 = mass of O2/molar mass of O2 = 192g/32g/mol = 6 mol. Therefore, the moles of H2 = 6mol *2 = 12 mol.
So the mass of H2 that reacts with O2 = moles of H2 * molar mass of H2 = 12 mol * 2 g/mol = 24 g
Answer:
mp -5; bp 30
Explanation:
That will be a liquid at room temperature, and it will evaporate quite quickly. Room temperature is generally considered 20 degrees Celsius. Choice B melts from a solid to a liquid at -5 degrees, so it's a liquid at room temperature as long as the boiling point is higher than 20 degrees.
When hydrogen atoms are energized by electricity, an emission spectrum of specific colors occurs because of the different wavelengths.
