Answer:
Genetic modification or GMOs can change foods. It's typically used to preserve foods, enlargen foods or create seedless grapes
Explanation:
Answer:
1) The value of Kc:
C. remains the same.
2) The value of Qc:
A. is greater than Kc.
3) The reaction must:
B. run in the reverse direction to restablish equilibrium.
4) The concentration of N2 will:
B. decrease.
Explanation:
Hello,
In this case, by means of the Le Chatelier's principle which is based on the shift a chemical reaction could have under some modifications, we have:
1) The value of Kc:
C. remains the same, since it just depend the reaction's thermodynamics as it is computed via:
2) The value of Qc:
A. is greater than Kc, since the reaction quotient is:
Thus, the lower the concentration of ammonia, the higher Qc, making Qc>Kc.
3) The reaction must:
B. run in the reverse direction to restablish equilibrium, since ammonia was withdrawn and should be regenerated to reach the equilibrium.
4) The concentration of N2 will:
B. decrease, since less reactant is forming the products.
Best regards.
Methane (CH4) forms the molecular solid.
<u>Explanation:</u>
- The molecules which are held together by intermolecular forces are called molecular solids. It is maintained by solids rather than bonds. The force which holds these solids are weaker than other solids.
- It consists of discrete molecules and the cohesive force which binds them together is Vanderwall's force, dipole-dipole interaction and hydrogen bonding. They are held together by an ionic bond or covalent bond.
- The weak intermolecular forces have relatively low melting points which are less than 300 degrees Celsius.
- Organic solvents dissolves Molecular solvents. Many of the molecular solids are soft electrical insulators with low density.
Answer:
pOH = -log[OH-]
log x =a <=> 10ª = x
so, if pOH is 10.75, we need to aply the anti log of it to get the [OH-], where x is [OH-] and a is pOH
using the calc, we have
-log [OH-] = 10.75 <=>10^(-10.75) = [OH-]
[OH-]= 1.78 x 10^(-11)
