Answer:

Carbon dixoide and water combine to form glucose and oxgen.

I hope this helped! :D

Explanation:

this process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

The molar heat capacity of a compound with the formula C2H6SO is 88.0 J/mol-K. The specific heat of this substance is __________

lisabon 2012 [21]

Answer : The specific heat of this substance is, 1.13 J/g.K

Explanation :

Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.

As we are given that the chemical formula of compound is, $C_2H_6SO$

First we have to calculate the molar mass of given compound.

Molar mass of $C_2H_6SO$ = $2(12g/mol)+6(1g/mol)+32g/mol+16g/mol$

Molar mass of $C_2H_6SO$ = 78 g/mol

Now we have to calculate the specific heat of this substance.

Specific heat of this substance = $\frac{\text{Molar heat capacity of a compound}}{\text{Molar mass of }C_2H_6SO}$

Specific heat of this substance = $\frac{88.0J/mol.K}{78g/mol}$

Specific heat of this substance = 1.13 J/g.K

Thus, the specific heat of this substance is, 1.13 J/g.K

An aqueous solution of potassium carbonate combine with a solution of calcium nitrate.

Charra [1.4K]

<span>This is an example of a double replacement or precipitation reaction. The solutions of potassium carbonate and calcium nitrate both contain dissolved ions so they will appear as clear, colorless solutions. When the two solutions are combined the calcium ions will combine with the carbonate ions to form an insoluble precipitate, which will appear as a white cloudiness. Potassium ions and nitrate ions will remain dissolved in the solution. They're called "spectator ions" because they're present as both reactants and products - they don't participate in the chemical reaction. </span>
