Answer: Nucleus of an atom is heavy and positively charged because nucleus is only made up of protons and neutrons.
Explanation:
The given data is as follows.
n = 2 mol, P = 1 atm, T = 300 K
Q = +34166 J, W= -1216 J (work done against surrounding)
=
Relation between internal energy, work and heat is as follows.
Change in internal energy (
) = Q + W
= [34166 + (-1216)] J
= 32950 J
Also, 
=
32950 J = 

1321.06 K + 300 K =
= 1621.06 K
Thus, we can conclude that the final temperature of the gas is 1621.06 K.
false
Explanation:
The more gravity pulls down on an object it gets heavier. Weight is just the amount of force gravity is putting on something. So if gravity is pulling it down more ut would get heavier.
Answer;
30 atoms
Explanation;
When glucose, C6H12O6, reacts with oxygen it produces carbon dioxide and water. If a molecule of glucose reacts completely with three molecules of oxygen, then 30 atoms would be produced because there are 24 atoms in glucose and 6 atoms in oxygen molecules.
The equation for the reaction would be;
C6H12O6 + 6O2(g) → 6CO2(g) + 6 H2O(l)
