H2PO4 1- --> H+ + HPO4 2-
HPO4 2- --> H+ + PO4 3-
Ka1 = [H+][H2PO4 1-] / [H3PO4]
Ka2 = [H+][HPO4 2-] / [H2PO4 1-]
Ka3 = [H+][PO4 3-] / [HPO4 2-</span>
Answer:
Meiosis produces haploid cells (gametes), which contain single chromosomes, or on-half the number of chromosomes in diploid cells. When a sperm and an egg join, the single chromosomes pair up, which results in genetic diversity in the offspring
Answer:
2.04 atm
Explanation:
The pressure of the gas can be found by using the equation of state for an ideal gas:
where
p is the gas pressure
V is the gas volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For this gas we have:
n = 0.316 mol (moles)
V = 4.00 L (volume)
T = 315 K (absolute temperature)
(gas constant)
Therefore, the gas pressure is
7 which is neutral ranges from 0-14
Answer:
Decomposition of hydrogen peroxide: 2H2O2 --> O2(g) + 2H2O(l) How many molecules of water are produced from the decomposition of 3.4g of hydrogen peroxide, H2O2
Explanation:
We are looking at the decomposition of hydrogen peroxide into water and oxygen gas:
2H2O2 --> 2H2O + O2
We are starting with 3.4 g of H2O2. First we need to convert this to moles. The molecular weight of H2O2 is 34 g/mol
3.4 g *...
