The cathode rays are also known as electrons. They are a stream of negatively charged particles.

<h3>What are cathode rays?</h3>

The term cathode rays were used by JJ Thompson to describe a stream of rays that emanate from the cathode in a cathode ray tube. These rays correspond to what we know today as electrons.

The cathode rays;

Travelled in straight lines
Depended on the nature of gas in the tube
Were deflected by electric and magnetic fields
Produced mechanical motion in objects on their path.

Electron beams such as cathode rays travel in a straight line.

<h3>What are Cathode rays?</h3>

Cathode rays are electrons that are observed in vacuum tubes, is streams of electrons are emitted by the negative electrode.

Cathode rays travel in straight lines and usually cast sharp shadows.
Cathode rays are negatively charged electrode
Cathode rays are usually deflected by an electric and magnetic field.

Therefore, cathode rays traveled in straight lines, they were the composition of the material from which they originated, and they carried a negative electrical charge.

Cobalt-60 is produced by neutron activation. in this process, one neutron is absorbed by the nucleus of the parent isotope. what

kkurt [141]

The parent isotope is cobalt-59 (see the picture below).

The mass number is 59 and atomic number is 27 of the parent isotope.

Neutron activation is the process in which atomic nucleus capture free neutron or neutrons.

Cobalt-60 is produced in nuclear reactors in process of neutron activation from parent isotope cobalt-59 (see the picture below).

Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.

Cobalt-59 and cobalt-60 are the isotopes of chemical element cobalt.

Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).

The likelihood that a chemical molecule will be reduced is called the

podryga [215]

<u>Answer:</u> The correct answer is standard reduction potential

<u>Explanation:</u>

Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

Standard reduction potential is defined as the tendency of a chemical substance to get reduced. It is denoted as $E^o$

The substance having highest positive $E^o$ potential will always get reduced and will undergo reduction reaction.

Hence, the correct answer is standard reduction potential

What is the molarity of a NaOH solution when 22.14 mL of 0.105 M oxalic acid is needed to

jeka57 [31]

The molarity of the NaOH solution required for the reaction is 0.186 M

We'll begin by writing the balanced equation for the reaction

H₂C₂O₄ +2NaOH —> Na₂C₂O₄ + 2H₂O

From the balanced equation above,

The mole ratio of the acid, H₂C₂O₄ (nA) = 1

The mole ratio of the base, NaOH (nB) = 2

From the question given above, the following data were obtained:

Volume of the acid, H₂C₂O₄ (Va) = 22.14 mL

Molarity of the acid, H₂C₂O₄ (Ma) = 0.105 M

Volume of the base, NaOH (Vb) = 25 mL

<h3>Molarity of the base, NaOH (Mb) =? </h3>

MaVa / MbVb = nA/nB

(0.105 × 22.14) / (Mb × 25) = 1/2

2.3247 / (Mb × 25) = 1/2

Cross multiply

Mb × 25 = 2.3247 × 2

Mb × 25 = 4.6494

Divide both side by 25

Mb = 4.6494 / 25

Therefore, the molarity of the base, NaOH solution is 0.186 M
