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.

Identify the following redox reactions by type. Check all that apply. (a) Fe + H2SO4 → FeSO4 + H2 combination decomposition disp
EastWind [94]

Answer :

(a) displacement reaction

(b) combination reaction

(c) disproportionation reaction

(d) displacement reaction

Explanation :

(a) The given balanced chemical reaction is,

Fe+H_2SO_4\rightarrow FeSO_4+H_2

This reaction is a single replacement reaction or displacement in which the the more reactive element (Fe) replace the less reactive element (H).

(b) The given balanced chemical reaction is,

S+3F_2\rightarrow SF_6

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or single product.

(c) The given balanced chemical reaction is,

2CuCl_2\rightarrow Cu+CuCl_2

This reaction is a disproportionation reaction in which the chemical species gets oxidized and reduced simultaneously.  It is also considered as a redox reaction.

(d) The given balanced chemical reaction is,

2Ag+PtCl_2\rightarrow 2AgCl+Pt

This reaction is a single replacement reaction or displacement in which the the more reactive element (Ag) replace the less reactive element (Pt).

1. carbon cycle
marin [14]

Explanation:

1. carbon cycle

all of the physical processes and chemical reactions that result in the movement of carbon between the biosphere (living forms) and the geosphere (water, earth, and atmosphere)

  Carbon cycle is the cyclic movement of carbon in various form on earth. This process entails both physical and chemical processes that ensures that carbon moves in different spheres of the earth. Carbon is one of the most important element in life. It is the building block of most organic processes on earth.

2. carbon footprint

a calculation that considers an individual's contribution to the process of global warming based on activities leading to greenhouse gas production

Carbon footprint is important in mapping the quota of carbon emitted into the atmosphere

It is the amount of greenhouse gases contributed into the atmosphere by individuals.

3. global warming

an overall increase in world temperatures that may be caused by additional heat being trapped by greenhouse gases

   It is the overall increase in global temperature. It has severe consequences.

  Global warming results when greenhouse gases in the atmosphere traps outgoing radiation in an anomalous way.

4. greenhouse gas

components of the air mixture that trap infrared (heat) energy

 Greenhouse gases are gases that prevents long wave radiation from leaving the earth surface. They absorb the gases in turn, warming occurs on earth.
