Answer:
2 m apart
Explanation:
Two cars of mass 3000 kg are 2 m apart what is the force of gravity between them using The universal law of gravitation
For a neutralization reaction, the value of q(heat of neutralization) is doubled when the concentration of only the acid is doubled.
A neutralization reaction is a reaction in which an acid reacts with a base to yield salt and water. Ionically, a neutralization reaction goes as follows; H^+(aq) + OH^-(aq) ------> H20(l).
The heat of neutralization (Q) of the system depends on the concentration of the solutions. Since Q is dependent on concentration, if the concentration of any of the reactants is doubled, more heat is evolved hence Q is doubled.

Answer:
v2= 5.404L
Explanation:
using Boyle's law
p1 x v1 = p2 x v2
101.325 x 4.31 = 80.8 x v2
v2= (101.325 x 4.31)\80.8
v2= 5.404L
What??? what language is this?
If you increase the temperature the air will try to expand. Since it is sealed and the air can't expand, it will apply higher pressure to the can because it will want to burst out. It works the other way around, if you cool it down it will lower the pressure.
