Answer:
H2O(s)
Explanation:
because it is a solid and an aqueous can not conduct electricity
Answer:
The first high part is Q4, then the low part is Q7, the following high part is Q6, and the energy moving from the next two high points is Q5.
Explanation:
The first high part is Q4, then the low part is Q7, the following high part is Q6, and the energy moving from the next two high points is Q5 because of the diagram.
Answer:
The answer to your question is 2 moles of Carbon
Explanation:
Carbon-12 means it has a molecular mass of 12g / mol. Mol is defined as the number of grams of an atom in one mol.
To solve this problem, we use proportions
12 g of Carbon ---------------- 1 mol of Carbon
24 g of Carbon -------------- x
x = ( 24 g x 1 mol ) / 12 g
x = 24 / 12
x = 2 mol of Carbon
Answer:
Mass = 0.000176 gram
Steps:
m = V × ρ
= 20 milliliter × 8.8 gram/cubic meter
= 2.0E-5 cubic meter × 8.8 gram/cubic meter
= 0.000176 gram
Explanation:
1) the element symbol, and thus name. For example, H is hydrogen, C is carbon and Fe is iron.
2) The atomic number, which is equal to the number of protons in the nucleus.
3) Since each proton has a +1 charge, you can also figure out the number of -1 electrons in the neutral atom.
4) The atomic mass, in atomic mass units, which is an average of 1 or more isotopes of the element.
