Answer:
Lava is hot liquid rock. When lava flows over solid ground, the solid ground beneath it increases in temperature. What happens to the molecules in the solid ground when the temperature is increasing? The energy of the molecules in the ground decreases.
Answer:
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
Answer : The number of moles of HCl neutralize is, 0.00824 moles.
Explanation :
The given balanced chemical reaction is:
First we have to calculate the moles of 
Molar mass of = 144 g/mol
Now we have to calculate the moles of HCl.
From the balanced chemical reaction we conclude that,
As, 1 mole of react with 4 moles of HCl
So, 0.00206 mole of react with 
moles of HCl
Thus, the number of moles of HCl neutralize is, 0.00824 moles.
If o100 ml of 3. zero m solution were diluted to 250 ml awareness of<u> 1.2 M.</u>
The concentration of the solution tells you how tons solute has been dissolved within the solvent. for example, in case you upload one teaspoon to two cups of water, the awareness could be stated as 1 t salt in keeping with 2 c water.
V1 = one hundred mL, M1 = 3 M
V2 = 250 mL, M2 = ?
observe Dilution regulation
M1*V1 = M2*V2
so
M2 = M1*V1/V2
M2 = 100/250*3
M2 = 1.2 M
Concentration (normally uncountable, plural concentrations) The act, procedure, or capability of concentrating; the system of becoming focused, or the country of being concentrated. The course of interest to a particular object. The act, technique or product of reducing the quantity of a liquid,
