Answer:
False
Explanation:
Glucose is a substrate which undergoes various chemical reactions in the mitochondria to produce ATP, which is the universal energy carrier.
Answer:
2.95 * 10^23 atoms
Explanation:
The number of atoms in a mole is always equal to <u>Avogadro's constant</u>, which is <u>6.02214076×10²³ mol⁻¹</u>.
To find the number of atoms in 0.490 moles of barium, multiply it with <u>Avogadro's constant</u>:
0.490 mol * 6.02214076×10²³ mol⁻¹ ≈ 2.9508 * 10^23
Convert to SigFigs (if necessary):
2.95 * 10^23
Answer:
% Mass of sand = 35.95%
% Mass of KBr = 64.05%
Explanation:
From the question given, we obtained the following:
Mass of mixture( KBr + sand) = 10g
Mass of sand = 3.595g
Mass of KBr = 10 — 3.595 = 6.405g
% Mass of sand = ( Mass of sand / mass of mixture) x 100
% Mass of sand = (3.595 / 10) x100
% Mass of sand = 35.95%
We can obtain the percentage of KBr by subtracting the percentage of sand from 100. This is illustrated below:
% Mass of KBr = 100 — 35.95
% Mass of KBr = 64.05%
as the amount of radiation received is proportional to 1/d^2
2m from source
for 1m readings are 50 count per minute
for 2m = 50 / (2)^2
50 / 4 = 12.5 count per minute
