Q: Carbonic acid can dissociate into hydrogen carbonate ions and what? Read this paragraph and choose the correct option from the provided answers: Carbon dioxide is slightly soluble in water. There is an equilibrium reaction that occurs as the carbon dioxide reacts with the water to form carbonic acid (H2CO3). Since carbonic acid is a weak acid, it can dissociate into protons (H+) and hydrogen carbonate ions (HCO 3 ). Choices: - protons - atoms - electrons - protons A:
(Answer)
protons

Q: Which theorem states that, if a population meets certain conditions, it will be in equilibrium? Read this paragraph and choose the correct option from the provided answers: The Hardy-Weinberg theorem states that, if a population meets certain conditions, it will be in equilibrium. In an equilibrium population, allele and genotype frequencies do not change over time. The conditions that must be met are no mutation, no migration, very large population size, random mating, and no natural selection. Choices: - hardy- jacksons theorem - hardy - henkel theorem - hardy - zeiss theorem - hardy-weinberg theorem A:
(Answer)
hardy-weinberg theorem
