C. ability to bond is a chemical property of tin.
Answer:
Humans have 23 pairs of chromosomes.
A trisomy is a chromosomal condition characterised by an additional chromosome.
A person with a trisomy has 47 chromosomes instead of 46.
Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
Explanation:
Reaction rate tells us how fast or how slow a reaction proceeds. There are certain reactions that are reversible. This means that the reactant can form products and the products can form back the reactants. The reaction will proceed until it reaches equilibrium. Equilibrium is achieved when the rate of the forward reaction is equal to the rate of the reverse reaction. In equation form:
Sample reaction
R1 + R2 <--> P1 + P2
rate(forward) = rate(reverse)
kf [R1][R2]=kr [P1][P2]
K = kf/kr = [P1][P2]/[R1][R2]
K is the equilibrium constant
kf is the rate constant of the forward reaction
kr is the rate constant for the reverse reaction
[R1], [R2], [P1], [P2] = concentration of reactants (R) and products (R) (examples)
Answer:
N2(g) + 3H2(g) → 2 NH3(g)
Explanation:
N2(g) + H2(g) → NH3(g)
We start equaling the number of N atoms in both sides multiplying by 2 the NH3.
N2(g) + H2(g) → 2 NH3(g)
So we equals the H atoms (there are six in products sites)
N2(g) + 3 H2(g) → 2 NH3(g)
Answer:
is the value of the equilibrium constant at this temperature.
Explanation:
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power equal to their stoichiometric ratios. It is expressed as
Partial pressures at equilibrium:
The equilibrium constant in terms of pressures is given as:
is the value of the equilibrium constant at this temperature.
