I believe the answer is C
Answer: The percentage by volume of alcohol will be 21%.
Explanation:
Given: Volume of solute = 14.7
Volume of solvent = 70
Formula used to calculate percentage by volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the percentage by volume of alcohol will be 21%.
The correct statements are as follows:
1. Reactants must collide, with proper orientations, with the energy greater than or equal to the activation energy for a reaction to take place. It is a correct statement, as to undergo a chemical reaction, the atoms should exhibit proper orientations and enough energy to reach the activation energy.
2. Increasing the concentration of a reactant increases the number of collisions, and the reaction goes faster. The mentioned statement is true, as when increasing the concentration of reactants, there should be more reactants. Thus, the collision will be more that makes the reaction to go faster.
3. The energy of a collision between the molecules or atoms must be greater than the activation energy to break the bonds. The given statement is true, as, with the increase in activation energy, the reaction will get slower. Thus, the energy of the reactants is greater in comparison to the activation energy, and then the reaction is faster to break the bond.
4. Decreasing the temperature decreases the kinetic energy of the reactants, and the reaction goes very slowly. The given statement is true, as when the temperature decreases, the kinetic energy that is required to dissociate the bond, also decreases. This undergoes a slow reaction.
Answer:
The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. ... In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.
