Heat energy is the amount of heat there is in a substance. This may be cold heat or warm heat. Temperature is how hot or cold a substance is. So because there is a higher volume of heat in the iceberg, we say it has more heat energy.
Answer:
53.29% of acetic acid is Oxygen
Explanation:
Step 1: Given data
Acetic acid it's molecular formula is HC2H3O2. This means it consists of 3 elements Carbon, Hydrogen and oxygen.
Step 2: the molar masses
The molecular mass of acetic acid is:
4* H = 4* 1.01 g/mole
2* C = 2*12 g/mole
2*O = 2* 16 g/mole
Total molar mass = 4+ 24+32 = 60.052 g/mole
Step 3: Calculate the mass percent
32 g of the 60.052 g is Oxygen
(32/60.052) *100% = 53.29%
53.29% of acetic acid is Oxygen.
Answer:
Eukarya
Explanation:
It's larger than a prokaryotic cell and it has a nucleus.
Compound monthly is correct
Half reaction N_2 H_4 (aq) → N_2 (g)Balancing atoms except O and H N_2 H_4 (aq) → N_2 (g)Balancing charge N_2 H_4 (aq)→N_2 (g)+4H^+ (aq)Balanced half reaction for oxidation of hydrazine to gaseous nitrogen is N_2 H_4 (aq)→N_2 (g)+4 H^+ (aq)+ 4e^-
