Answer: Yes.
Explanation: Food contains chemical potential energy. As our bodies digest it, the stored energy is converted into energy for us to move and grow.
Given,
Radius of sphere , r = 8cm
Volume of sphere = 4/3 pi r^3
=> volume of sphere = 4/3 x 3.14 x 8 x 8 x 8 = 2143.6 cubic units
It’s charge was neutral due to the equal number of protons and electrons. when it becomes an ion it loses 3 electrons leaving behind only 10. the answer is 10. the equation is +13 +(-10)=+3
Pretty much, for solids draw the molecules close together and rigid, for liquids, the molecules are spaced apart a little and not all lined up
Answer:
The pressure in the gas is 656mmHg
Explanation:
In calculating the pressure of the gas;
step 1: convert the height of the mercury arm to mmHg
9.60cm = 96.0 mmHg
step 2: convert 752 torr to mmHg
I torr is 1 mmHg
752 torr = 752mmHg
Step 3: since the level of mercury in the container is higher than the level of mercury exposed to the atmosphere, we substrate the values to obtain our pressure.
So, 752mmHg - 96mmHg = 656mmHg
The pressure in the gas container is therefore 656mmHg.
N. B : if the mercury arm is in lower position, you add.
