Answer:
C. 12.8 liters.
Explanation:
The Standard Temperature and Pressure (STP) of a gas are 273.15 K and 100 kilopascals. From Avogadro's Law, a mole of carbon dioxide contains 
molecules. If we suppose that carbon dioxide behaves ideally, then the equation of state for ideal gas is:
(1)
(1b)
Where:
- Pressure, measured in pascals.
- Volume, measured in liters.
- Amount of molecules, no unit.
- Avogadro's number, no unit.
- Ideal gas constant, measured in pascal-liters per mole-Kelvin.
- Temperature, measured in Kelvin.
If we know that 
, 
, 
, 
and 
, then the volume of carbon dioxide at STP is:
Therefore, the correct answer is C.
When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. ... “Convection is the transfer of heat through the movement of a fluid such as water or air.
Longer pendulums swing with a lower fequency than shorter pendulums. The force of gravity accelerates the pendulum down. The momentum built up by the acceleration of gravity causes the mass to swing in the opposite direction to a height equal to the original position. So therefore I think the answer your looking for is gravity.
Answer:
Sodium and chlorine ions come together to form sodium chloride or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-. Together, they form a neutral compound because the ions balance each other out.
Explanation:
1 calcium chloride is equal to <span> 0.00901030779211 mole.
if we just multiply that by 37.793 we get </span><span>0.34052656238 moles of calcium chloride.</span>
