The atom in a sample of an element must contain nuclei with the same number of?
Answers
Answer: Protons
The atom in a sample of an element must contain nuclei with the same number of protons. If the protons change in number, then the element will modify as well.
Thank you!

What is glucose ?
A basic sugar, glucose has the chemical formula C6H12O6. The most prevalent monosaccharide, a type of carbohydrate, is glucose.
The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals, or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
The brain is the most energy-hungry organ in the body and uses half of the body's sugar energy due to its abundance of nerve cells, or neurons. Thinking, memory, and learning are all tightly correlated with blood glucose levels and how effectively the brain uses this substance.
Thus, a homopoloymer of glucose is corn starch.

Therefore water is the solvent.
Solvent is a particle which dissolves Solute in a solution. It is usually larger than solute in quantity.
In your case above, Calcium chloride is in less quantity, and thus, Calcium chloride shall be called solute.
(2) 100 K and 25 atm
(3) 400 K and 0.25 atm
(4) 400 K and 25 atm
Answers
Answer : The correct option is, (3) 400 K and 0.25 atm
Explanation :
The conditions for ideal gas are :
Ideal gas are those gas that has no intermolecular attractions.
Ideal gas are those gas that have negligible volume.
The ideal gas equation is,
The conditions for real gas are :
Real gas are those gas that have intermolecular attractions.
Real gas are those gas that have volume.
The real gas equation is,
A real gas behave ideally at high temperature and low pressure condition.
From the given options, option (3) have high temperature and low pressure is the correct option.
Hence, the 400 K and 0.25 atm conditions of temperature and pressure does a sample of neon behave most like an ideal gas.
Therefore, (3) 400K and 0.25 atm is the correct answer.

b. 25.0 g/mol
c. 47.5 g/mol
d. 56.0 g/mol
e. 125 g/mol
Answers
Step 1: You must find the mol amount of that 12.5g mass.
12.5 / 5 = 2.5 mol
Step 2: Now find the molecular mass of that gas "at STP" (STP- is 22.4 L)
2.5 x 22.4 = 56 g/mol
