The question is incomplete, the complete question is;

Atom Number of protons Number of electrons Number of neutrons

1 39 39 52

2 40 40 50

3 39 39 54

4 40 40 51

Based on the information that is given, which atom in the table has the highest mass?

a. 1

b. 2

c. 3

d. 4

Answer:

c

Explanation:

The relative atomic mass is given as; number of protons + number of neutrons. If we take the relative atomic mass of each of the options;

1) 39 +52 = 91

2) 40+50 = 90

3) 39 + 54 = 93

4) 40 + 51 = 91

Thus 3 has the highest mass as seen above, hence the answer given.

Correct each of the following names:<br> (c) MgCr₂O₇ is magnesium dichromium heptaoxide
zhenek [66]

Magnesium dichromate is the correct name of the compound MgCr₂O₇.

<h3>What is Molecular Formula ?</h3>

The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.

<h3>What is Oxidation State ?</h3>

Oxidation state is also known as oxidation number. It is defined as the atom is equal to the total number of electrons which have been removed from the element in order to form chemical bond with other atom.

Magnesium dichromate contains the Magnesium ion and chromate ions. Magnesium ion is represented as Mg⁺². Oxidation state of magnesium is +2. The chromate ion is represented as Cr₂O₇⁻². Oxidation state of chromate ion is -2.

Thus from the above conclusion we can say that The correct name of the compound MgCr₂O₇ is Magnesium dichromate.

The practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to gr
Marianna [84]

Answer:

True

Explanation:

The greenhouse effect is the process whereby there is radiation from a atmosphere planet and the planet increase the temperature of the planet's surface to a temperature above normal.In this process the Earth's atmosphere becomes thicker with the influence substances such as gases

and the radiation coming from the sun is trapped, then the Earth becomes warmer. Green house effect is seen in global warming.

Carbon neutral can be described as a process of removing huge amount of carbon dioxide from the atmosphere in order to achieve zero carbon neutrality.It is also reffered to as carbon neutrality, and this can be achieved by actions of organizations, businesses and individuals .

Carbon neutral can be achieved in two ways;

: 1.) Maintaining a balance between carbon dioxide emissions and carbon removal by means of the process called carbon offsetting

2 ) the process of removal of carbon dioxide from the atmosphere in order to balance up emissions in another place.

Carbon positive is crucial to increase the positive influence of our daily activities on climate change and our resources.

while reduce the negative effect of our activities and business on evironment.

Therefore, the practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to greenhouse gas emissions by purchasing credits from "carbon-positive" projects to balance out emissions is true because the harmful gasses that is been released to the atmosphere is balance up by the carbon neutral process hence the reduction in green house effect.

What is the reduction half equation of Fe(s)+ 2 HC2H3O2(aq) → Fe(C2H3O2)2(aq) + H2(g)
Sonbull [250]

Answer:

2 H⁺ + 2e = H₂    ( reduction )

Explanation:

Fe( s ) + 2 CH₃COOH = Fe ( OOCCH₃ ) ₂ + H₂

Fe( s ) = Fe⁺² + 2e     ( oxidation )

2 H⁺ + 2e = H₂    ( reduction )
