I think the answer is 4.)Cumulonimbus but I'm not 100% sure
The core of an atom contains protons and neutrons.
Answer:
Identifying whether or not an element is an ion is a very simple process. Identify the charge of the element. ... The number of electrons is equal to the atomic number minus the charge of the atom. Refer to an element with either a positive or negative charge as an ion.
Answer:
I believe the answer is C.
Explanation:
epic gamer explanation: C + 02 = CO2
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.
