Answer:
First: H8C3O2
Second: H24C9O6
Explanation:
Convert the grams to moles
Grams per hydrogen: 1.008
Grams per carbon: 12.011
Grams per oxygen: 15.999
10.59/1.008 = 10.51 moles of hydrogen
47.37/12.011 = 3.94 moles of carbon
42.04/15.999 = 2.63 moles of oxygen
Divide all the moles by the lowest number of moles
10.51/2.63 = 3.99 (Round it to 4 for simplicity)
3.94/2.63 = 1.5
2.63/2.63 = 1
Multiply them to get whole numbers
4 x 2 = 8
1.5 x 2 = 3
1 x 2 = 2
To find the molecular formula
Find the mass of the empirical formula
1.008 x 8 = 8.064
12.011 x 3 = 36.033
15.999 x 2 = 31.998
Mass = 76.095 g/mol
228.276/76.095 = 3
Multiply the empirical formula number by 3 to get H24C9O6
Answer:
They should test their answer over again. Same thing with math.
Explanation:
If they are doing an experiment, do the experiment over and reach out to other scientits to validate your results
Presence of Oxygen in mitochondria is called Aerobic conditions and under this aerobic conditions Pyruvic acid is converted into Acetyl Co.A which enters Krebs' cycle
while in absence of oxygen which called Anaerobic conditions pyruvic acid is converted into Lactic acid to avoid accumulation of NADH⁺ which inhibit glycolysis and provide NAD⁺ required for glycolysis

False. Bonds between nonmetals are covalent.
The heat of the reaction is an extensive property: it is proportional to the quantity of the quantity that reacts.
The change in enthalpy is a measured of the heat evolved of absorbed.
When the heat is released, the change in enthalpy is negative.
The reaction of 2 moles of Na develops 368.4 kj of energy.
Calculate the number of moles of Na in 1.90 g to find the heat released when this quantity reacts.
Atomic mass of Na: 23 g/mol
#mol Na = 1.90 g / 23 g/mol = 0.0826 mol
Do the ratios: [368.4 kj/2mol ] * 0.0826 mol = 15.21 kj.
Then the answer is that 15.21 kj of heat is released (evolved)
