The molar ratio is 1:2 because there is 1 hydrogen molecule to 2 hydrofluoride molecules
Answer:
1. Main sequence stars have different masses. The common characteristic they have is their source of energy. They burn fuel in their core through the process of fusing hydrogen atoms into helium.
2. Supergiants are among the most massive and most luminous stars. Supergiant stars occupy the top region of the Hertzsprung–Russell diagram with absolute visual magnitudes between about −3 and −8. The temperature range of supergiant stars spans from about 3,400 K to over 20,000 K.
3. Supergiants develop when massive main-sequence stars run out of hydrogen in their cores.
4. a supernova occur When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion.
5. when a star has reached the end of its life and explodes in a brilliant burst of light

Answer:
Hi, this is a super vague question, so its pretty confusing to answer. Could you please be a bit more specific?
If you are referring to chemistry, then how you tell "what is what" is by the molecular makeup of an element (Periodic table), and "how that..affects what", chemical reactions can occur between elements
The mass of oxygen required is 17.06 g; the mass of carbon dioxide produced is 300 g; the mass of copper (ii) nitrate produced is 16.7 g.
<h3>What is the equation of the synthesis of water from hydrogen and oxygen?</h3>
The equation of the synthesis of water from hydrogen and oxygen is given as follows:
The grams of oxygen required is given below:
The equation of the combustion of propane is given as follows:
The mass of carbon dioxide produced is given below:
The equation of the reaction of copper and silver nitrate is given as follows:
Therefore, the mass of oxygen required is 17.06 g; the mass of carbon dioxide produced is 300 g; the mass of copper (ii) nitrate produced is 16.7 g.

<span>Compared to a weak acid, a strong acid has a greater habit of losing it's proton (hydrogen). For example, when hydrochloric acid (strong) encounters water, it is much more likely to donate its hydrogen to water, compared to nitrous acid (weak).</span>
