D.The transferring of thermal energy from the sun to the earth!
Answer: The change in volume will be 9.30 L
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
The change in volume will be (44.3-35.0)L = 9.30 L
Well i have done a little of chemistry but i think it would be A. Of you look at whats reacting the product the ya A IS YOUR ANSWER I HOPE I DIDN'T GET IT WRONG
Answer:
There are two chloride ions for each calcium ion
Explanation:
The compound has to have an overall neutral charge. Meaning that the positive charges from calcium have to be canceled out by the negative charges of chlorine.
If there are two chloride ions for each calcium ion, the charges would cancel themselves out (2 * -1 would cancel out with +2).
Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O2) and carbon dioxide (CO2). These small, fat soluble gasses and other small lipid soluble molecules can dissolve in the membrane and enter or exit the cell following their concentration gradient.
