Solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the liquid and is inversely proportional to the temperature.
So, the solubility of <u>gas </u>in water decreases as the temperature increases.
Calcium belongs to the alkaline earth metal group. Within a group, the melting point decreases from top to bottom. This is because the as the atomic radii increases the outer valence electrons are shielded by the inner electrons and experience a lower nuclear attraction. As a result the bonds can be broken easily which lowers their melting point.
The three elements below Calcium ib Group II A which have a lower melting point are: Strontium (Sr), Barium (Ba) and Radium (Ra)
Answer:
When the Zebra arrived they ate all the food so the Unionid mussels declined as they died from the lack of food. Causing the Zebra Zebra numbers to increase and Unionid numbers to decline.
Answer:
100 torr
Explanation:
First find the formula you need to use, this will be...
P2 = V1 x P1 / V2
Next, fill in the numbers, this will be...
P2 = ? (we are trying to find this)
P1 = 760 torr
V1 = 1.5 L
V2 = 11.4 L
Next, turn into new formula (just rearrange)
P2 = 1.5 L x 760 torr / 11.4 L
Next, do the math. This should get you...
<u>100 torr</u> as your answer
