The answer is 9. Calcium nitrate is made up
of 3 different elements that equal 9 atoms.
Cell theory states that all the living organisms are made up of basic structural and functional units, cells. All cells divide and give rise to new cells. All the cells have similar chemical composition. The nuclei acid DNA present in the chromosomes helps in carrying hereditary information from generation to generation. So, in order to sustain life the cells must contain DNA either enclosed in the nucleus or freely floating in the cytoplasm.
The answer to this question would most definitely be the last one
The answer should go like...
<em>Cube #1 to Cube #3</em>
<em>Cube #2 to Cube #1</em>
<em>Cube #2 to Cube #4</em>
<em>Cube #4 to Cube #3.</em>
Answer:
Explanation:
Here, we want to calculate the number of moles of methane in the container
From the ideal gas law:
where:
P is the pressure inside the container which is 3 atm
V is the volume of the container which is 2 L
R is the molar gas constant which is 0.0821 Latm/mol.k
T is the temperature in Kelvin (we convert the temperature in Celsius by adding 273 : 273 + 77 = 350 K)
n is the number of moles that we want to calculate
Substituting the values, we have it that:
