Answer:
1,2,3,5,7,8,9
Explanation:
are all physical properties
<u>Answer:</u>
17%
<u>Explanation:</u>
Mass of a piece of copper calculated by student = 8.3 grams
Actual mass of copper = 10 grams
We know the formula for the percent error:
Percentage error = (| experimental value - actual value | / actual value) * 100
So substituting the given values in the above formula:
Percent error = (|8.3 - 10| / 10) * 100 = (1.7/10) * 100 = 17%
The phase change that releases the most energy is deposition, when gas turns into a solid. It takes the absorption of energy to melt a solid into a liquid, and even more energy to vaporize the liquid into a gas. Hence, the reverse process (from solid to gas) will result in the greatest release of energy.
C = covalent
I = Ionic
(I'm lazy to an extent)
An ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals.
H2 = C
Cl2 = C
O2 = C
HCl = C
LiF = I
NaCl = I
NaF = I
MgF = I
NH3 = C
CH4 = C
CO2 = C
NaP = I
N2 = C
NF3 = C
Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person's body has the same DNA.
EXPLANATION: SO THE CORRECT ANSWER IS
"NUCLEIC ACID"
