Answer:

(a) Rb

$1s^22s^22p^63s^23p^63d^{10}4s^24p^65s^1$

(b) Ge

$1s^22s^22p^63s^23p^63d^{10}4s^24p^2$

$1s^22s^22p^63s^23p^6$

Explanation:

(a) Rb

Atomic number = 37

The electronic configuration is -

$1s^22s^22p^63s^23p^63d^{10}4s^24p^65s^1$

(b) Ge

Atomic number = 32

The electronic configuration is -

If during an experiment zinc was found to be more reactive than lead or copper, zinc would be considered the strongest _____.

densk [106]

Zinc would be considered the strongest reducing agent.

<h3>Reducing agent</h3>

A reducing agent is a chemical species that "donates" one electron to another chemical species in chemistry (called the oxidizing agent, oxidant, oxidizer, or electron acceptor). Earth metals, formic acid, oxalic acid, and sulfite compounds are a few examples of common reducing agents.

Reducers have excess electrons (i.e., they are already reduced) in their pre-reaction states, whereas oxidizers do not. Usually, a reducing agent is in one of the lowest oxidation states it can be in. The oxidation state of the oxidizer drops while the oxidizer's oxidation state, which measures the amount of electron loss, increases. The agent in a redox process whose oxidation state rises, which "loses/donates electrons," which "oxidizes," and which "reduces" is known as the reducer or reducing agent.

PLEASE SOMEONE SOLVE THE QUESTION OR I'M GONNA FAIL

Explanation:

Purpose and Theory: A tablet of vitamin C contains the active ingredient called ascorbic acid (HC,H,0.).

Ascorbic acid is an organic acid which is a white power and is soluble in water.

In the following microtitration lab you will be grinding up a vitamin C tablet

, and using a 0.10 g sample of the

vitamin C powder, which will be dissolved in 20-40 mL of water. This solution will be used to determine the

quantity of ascorbic acid in a commercial vitamin C tablet.
