Answer: will be five times higher
If 4 moles of gas are added to a container that already holds 1 mole of gas, the pressure inside the container
will be five times higher due to the change in the amount of gas.
Explanation:
4 moles of gas + 1 mole of gas = 5 moles of gas.
Also, the ideal gas equation pV = nRT
show that pressure is directly proportional to number of moles; so, if 1 mole of gas contains molecules that move randomly and freely under pressure inside the container; addition of 4 extra moles will sum up to 5moles of gas molecules moving randomly under pressure, and that is five times higher as well.
The electron configuration describes the electrons of Magnesium
Answer:
Yes
Explanation:
The temperature of the reaction mixture rises as energy is released in an exothermic process. The temperature drops when energy is absorbed in an endothermic reaction. Placing a thermometer in the reaction mixture will allow you to track temperature changes.
Answer:
0.36M HCl
Explanation:
The reaction of Mg(OH)₂ with HCl is:
Mg(OH)₂ + 2HCl → MgCl₂ + 2H₂O
<em>Where 1 mole of magnesium hydroxide reacts with 2 moles of HCl</em>
<em />
To solve this question, we need to find the moles of Mg(OH)₂ that reacted and, with chemical equation, solve for the moles of HCl and its molarity (Using the 10.00mL = 0.01000L) as follows:
<em>Moles of Mg(OH)₂:</em>
18mL = 0.018L * (0.100mol / L) = 0.0018 moles Mg(OH)₂
<em>Moles HCl:</em>
0.0018 moles Mg(OH)₂ * (2 moles HCl / mol Mg(OH)₂) = 0.0036 moles HCl
<em>Molarity HCl:</em>
0.0036 moles HCl / 0.0100L =
<h3>0.36M HCl</h3>
