The kinetic energy will increase. the molecules in a gas will move freely so it moves crazy like 10,000 cheetah on a run going in different directions
Answer:
Explanation:
The neutral one has atomic structure 1s2 2s2
The one with a positive charge could be 1s2 2s which has lost one of its 2s electrons.
Answer:
The correct answer is that both molecular motion, pressure and temperature increase as volume reduces.
Explanation:
A reduction in volume changes the molecular motion, temperature and pressure of the system. When the volume of the container decreases, this causes the pressure to increase, the temperature to increase and the molecular motion to increase. This is because a liquid and a solid are incompressible, so by reducing the volume of a gas, the molecules increase their movement as the temperature of the system increases, which is due to the increased pressure applied to reduce the volume of the system.
Have a nice day!
Answer:
the diagram illustrates an exothermic reaction , because if you look at the graph it starts low than goes high than fall not to far from the top , you can determine how the total change an endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
The pH of the solution is obtained as 2.23.
<h3>What is the pKa?</h3>
The pKa shows the extent to which an acid is dissociated in solution. Now we have;
HCOOH(aq) + H2O(l) ⇔ HCOO-(aq) + H30+(aq)
Ka = [HCOO-] [ H30+]/[ HCOOH]
But = [HCOO-] = [ H30+] = x
Ka = x^2/[HCOOH]
x = √Ka [HCOOH]
x = √0.19 * 1.8×10−4
x = 5.8 * 10^-3
pH = - log (5.8 * 10^-3)
pH = 2.23
