Explanation:
To dissolve, solvent particles must come in contact with solvent particles. Particles of hot water are moving much more rapidly than particles of cold water. Hence, in hot water more water particles will come in contact with hot chocolate powder than in cold water, resulting in faster dissolving.
Answer: fMRI
Explanation:
fMRI stands for Functional Magnetic Resonance Imaging. It is an imaging scan that helps to evaluate the activities of the brain through changes that occurs in line with the flow of blood, and this is because there is a connection between neuronal activation and blood flow in the cerebral. It must be noted that the rate of blood flow in a particular area of the brain increase when such part is under use.
Answer:
Genotype
Explanation:
The genotype is the genetic makeup that is responsible for a particular trait. Genotype is the combination of alleles that were inherited from the parents. Unlike phenotype, genotype is not observable, but it determines what trait will be physically expressed. For example, if Dimples (D) is dominant over no dimples (d) and a woman is heterozygous for dimples the genotype woud be:
Dd
Answer:
Explanation:
From the reaction ; aA + bB → cC + dD
1) Keq = equilibrium constant = [A]^a [B]^b / [C]^c [D]^d
where [A] = [B] = [C] = [D] are the concentrations of reactants A, B, C and D respectively.
2) What is the actual free energy change of the reaction above? ;
- ΔG is the differences between the sum of the free energies of the product and the reactant.
- Mathematically; ΔG = (cΔGC + dΔGD) - ( aΔGA + bΔGB)
- ΔG, in terms of reaction quotient ; ΔG = ΔG(standard) + RT lnQ
where R = gas constant and T = temperature.
3) What is the standard free energy change of the reaction above;
- ΔG(Reaction) = Summation ΔGf(products) - summation ΔGf(reactants)
- where summation ΔGf = standard free energy of formation
