Answer:
If the temperature and volume ot a gas increases, the r.m.s. velocity of the molecules in the gas will be 2 times the original r.m.s. molecular velocity.
If T doubles while V is held constant, the new net internal energy of the gas will be 2 times the original internal energy of the gas.
Explanation:
Temperature and root mean square velocity are directly proportional to one anoth. If the temperature increases, root mean square velocity also increases and vice versa, while temperature is also directly proportional to the internal energy of the gas molecules, higher the temperature, higher will be the internal energy and lower the temperature so internal energy will be decreased.
Answer: True
The formula of weight is w = mg, where m is the mass and g is the acceleration of gravity. If you want to calculate an object's weight, you need to know the two components: mass and gravity.
You only need to know the mass of the object because the acceleration of gravity is ALWAYS (assuming the object is on Earth) 9.8 m/s^2.
mass Hydrogen=9.376 g

Reaction
2H₂+O₂⇒2H₂O
mass H₂ = 10 g
mol H₂(MW=2 g/mol) :
10 : 2 = 5
mass O₂=5 g
mol O₂(MW=32 g/mol) :
5 : 32 = 0.156
O₂ limiting reactant
mol H₂: mol O₂ = 2: 1, so mol H₂ :
2 x 0.156 = 0.312
mol H₂ :
5 - 0.132 =4.688
mass of H₂ :
4.688 x 2 =9.376 g

I don’t know what kind of response you want to be written but here are some examples if you are trying to recommend or not recommend your science class to a friend:
Positive View:
Dear (Friend),
My science course is really interesting!
You would not believe the topics we are going to learn this year! We are going to learn about the (topic), (topic), and (topic)! Not only that, did you know that (fun fact)? This science course is probably one of the best classes I ever taken! You should take one of these classes if you are also interested in it.

Negative View:
Dear (Friend),
My science course is not as interesting and exciting as I thought.. It doesn’t have topics about (topic), (topic), and (topic)... I recommend that you don’t take this course. It really is bad. There is not much to be learned here. But if you really want to join the course, I won’t stop you. After all, that is what you wanted. But I will give good luck to you since you might need it. Don’t say that I didn’t warn you.

Dear (Friend),
The science course I’m taking is actually not that bad. It have topics that I don’t really understand but I guess I will just learn it along the school year. If you want to know what kind of topics, the topics they are (topic), (topic), and (topic). They seem hard but if I read from a textbook, I start to understand a bit. Though I wouldn’t recommend it to others, it actually have very interesting knowledge to know about. If you want to join, then join.
