IT IS D FOCAL POINT
P.S. im in middle school not trying to brag
mol CaCl₂ = 1.2 x 10²⁴ : 6.02 x 10²³ = 1.993
mass = 1.993 x 111 g/mol = 221.223 g
Answer:
0.501 L
Explanation:
To solve this problem we will use Boyle,s Law. According to this law "The volume of given amount of gas is inversely proportional to applied pressure at constant temperature".
V∝ 1/P
V= K/P
VP=K
Here the K is proportionality constant.
so,
P1V1 = P2V2
P= pressure
V= volume
Given data:
P1= 1 atm
V1= 461 mL
P2= 0.92 atm
V2= ? (L)
To solve this problem we have to convert the mL into L first.
1 L = 1000 mL
461/1000= 0.461 L
Now we will put the values in the equation,
P1V1 = P2V2
V2= P1V1/ P2
V2= 1 atm × 0.461 L / 0.92 atm
V2= 0.501 L
Answer:
A. It will shift to the left
Explanation:
In the equilibrium:
C(s) ⇄ CO2(g)2CO(g)
The system will shift to the right if any change stimulate the production of gas -LeChatelier's principle-; in the same way, if a change doesn't favors the production of gas the system will shift to the left producing less gas.
The changes that increasing the pressure of the system, doesn't favors the gas production doing the system shift to the left.
A gas that is heated expands itsellf doing the pressure increases.
In the same way, if you compress the gas, the gas increases its pressure.
Thus, both changes increase pressure of the gas doing the system shift to the left.
<h3>A. It will shift to the left
</h3>
Explanation:
Once the earth's atmosphere was formed it really hasn't changed since, this is due to many reasons. Whatever created the earth's atmosphere (we don't know) has long disappeared, because of this the atmosphere cannot change, as there is nothing on earth that can change it (that we know of at least). Hopefully this helps.
