An atom that has gained or lost electrons is called _____.

2 answers:

7 0

It called cation, Well, When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost, the resulting ion is called cation and when electrons are gained, the resulting ion is called an anion. So, Cations have a net positive charge, while anions have a net negative charge. it is true.

What multiplicities are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde?

Flauer [41]

The multiplicities that are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde is a singlet, a triplet, and a quartet. The correct option is E.

<h3>What is off-resonance decoupling?</h3>

Off-resonance decoupling is a process of removing all hydrogen and carbon coupling from a signal except for the place which is near the nucleus or joined with the nucleus.

In NMR also, the coupling of hydrogen and carbon is removed except for the place near the nucleus.

Thus, the correct option is E) a singlet, a triplet, and a quartet.

The temperature of 170 g of a material decreases by 20.0⁰C when it loses 3050 J of heat. What is its specific heat

qaws [65]

Answer:

0.897 J/g.⁰C

Explanation:

Given the following data:

m = 170 g (mass)

ΔT = 20.0⁰C (change in temperature)

q = 3050 J (amount of heat)

The amount of heat (q) is calculated as follows:

q = m x Cp x ΔT

Thus, we introduce the data in the mathematical expression to calculate the specific heat (Cp):

Cp = q/(m x ΔT) = 3050 J/(170 g x 20.0⁰C) = 0.897 J/g.⁰C

True or false, some molecules have the same molecular formula as their empirical formula.

Fiesta28 [93]

Answer:

<u>True</u>, some molecules have the same molecular formula as their empirical formula.

Explanation:

The empirical formula of many compounds may be the same. Formaldehyde, for example, has the chemical formula CH2O, which is equal to the empirical formula of glucose. Each molecule of formaldehyde has one carbon atom, two hydrogen atoms, and one oxygen atom.

If the [H+] = 0.01 M, what is the pH of the solution, and is the solution a strong acid, weak acid, strong base, or weak base?

lana66690 [7]

Answer:

2, strong acid

Explanation:

Data obtained from the question. This includes:

[H+] = 0.01 M

pH =?

pH of a solution can be obtained by using the following formula:

pH = –Log [H+]

pH = –Log 0.01

pH = 2

The pH of a solution ranging between 0 and 6 is declared to be an acid solution. The smaller the pH value, the stronger the acid.

Since the pH of the above solution is 2, it means the solution is a strong acid.
