8 because atomic number is the same as number of protons, protons and electrons have the same amount so that the element is neither positive nor negative.
Answer:
Will the electronegativity of barium be larger or smaller than that of strontium? Explain. EN of Ba (0.89) is smaller than EN of Sr (0.95). Because of larger size and more inner core e- shielding, Barium will more readily share its valence electron in the 6s sublevel than Sr will share it valence e- in the 5s sublevel.

Answer:
The rate is a mathematical relationship obtained by comparing reaction rate with reactant concentrations.
Answer:
B. A tertiary alcohol; a secondary alcohol
Explanation:
Grignard reagent has a formula RMgX where X is a halogen, and R is an alkyl or aryl group.
Grignard reagent reacts with aldehydes and ketones to form alcohol. However the classification (that is; Primary, secondary and tertiary) varies depending on which it reacts with.
2-butanone is a ketone.
Ketones reacts with Grignard reagent to form tertiary alcohol
Butanal is an aldehyde.
Aldeyde reacts with grignard reagent to form Secondary alcohol
The answer is; Tertiary alcohol; Secondary alcohol
