Answer: Earth's average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space and 70 percent is absorbed. A sensor aboard NASA's Terra satellite is now collecting detailed measurements of how much sunlight the earth's surface reflects back up into the atmosphere.

Answer:

Explained below

Explanation:

The human body has a normal core temperature of around 37°C to 38°C.

Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.

If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.

Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.

D. to go skiing

Barbecue is usually a summer activity, so we eliminate that.

Answer:

Option D is correct.

H₂O + CO₂      →    H₂CO₃

Explanation:

First of all we will get to know what law of conservation of mass states.

According to this law, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Example:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Now we will apply this law to given chemical equations:

A) H₂ + O₂   →    H₂O

There are two hydrogen and two oxygen atoms present on left side while on right side only one oxygen and two hydrogen atoms are present so mass in not conserved. This equation not follow the law of conservation of mass.

B) Mg + HCl   →   H₂ + MgCl₂

In this equation one Mg, one H and one Cl atoms are present on left side while on right side two hydrogen, one Mg and two chlorine atoms are present. This equation also not follow the law of conservation of mass.

C) KClO₃      →     KCl + O₂

There are one K, one Cl and three O atoms are present on left side of chemical equation while on right side one K one Cl and two oxygen atoms are present. This equation also not following the law of conservation of mass.

D)  H₂O + CO₂      →    H₂CO₃

There are two hydrogen, one carbon and three oxygen atoms are present on both side of equation thus, mass remain conserved. Thus is correct option.

The chemical reaction that follows the conservation of mass has been the formation of hydrogen carbonate. Thus, option D is correct.

The conservation of mass states that the mass of the reactant and products has been equal. The mass can be calculated in terms of the number of atoms.

(A) [tex]\rm H_2\;+\;O_2\;\rightarrow\;H_2O[/tex]

The number of atoms of Hydrogen:

Reactant = 2

Product = 2

The number of atoms of Oxygen:

Reactant = 2

Product = 1

The number of atoms of products and reactant is not equal, Thus, the reaction did not follow the conservation of mass.

(B) [tex]\rm Mg\;+\;HCl\;\rightarrow\;H_2\;+\;MgCl_2[/tex]

The number of atoms of Mg:

Reactant = 1

Product = 1

The number of atoms of H:

Reactant = 1

Product = 2

The number of atoms of Cl:

Reactant = 1

Product = 2

The number of atoms of products and reactant is not equal, Thus, the reaction did not follow the conservation of mass.

(C) [tex]\rm KClO_3\;\rightarrow\;KCl\;+\;O_2[/tex]

The number of atoms of K:

Reactant = 1

Product = 1

The number of atoms of Cl:

Reactant = 1

Product = 1

The number of atoms of O:

Reactant = 3

Product = 2

The number of atoms of products and reactant is not equal, Thus, the reaction did not follow the conservation of mass.

(D) [tex]\rm H_2O\;+\;CO_2\;\rightarrow\;H_2CO_3[/tex]

The number of atoms of H:

Reactant = 2

Product = 2

The number of atoms of O:

Reactant = 3

Product = 3

The number of atoms of C:

Reactant = 1

Product = 1

The number of atoms of products and reactant is equal, Thus, the reaction follows the conservation of mass.

The chemical reaction that follows the conservation of mass has been the formation of hydrogen carbonate. Thus, option D is correct.
