Within a plant, water (H2O) and carbon dioxide (CO2) can be combined (using the energy of sunlight) to produce glucose (C6H12O6)

and oxygen (O2). If you were to write out this chemical reaction, water and carbon dioxide are each an example of a(n) while glucose and oxygen are each an example of a(n)

Answer:

Reactants and products

Explanation:

The reaction can be writen inthis way

6H_{2}O + 6CO_{2}⇒C_{6}H_{12}O_{6} + 6O_{2}

Here we can notice that water and carbon dioxide are combined, so they are the reactants and produce glucose and oxygen that are the products.

Ksivusya [100]

Ah , a cup of hot chocolate is alot of chocolate. Im gonna drool ; )

Well , heat flows from an area of high temperature to an area of low temperature. Here , hot chocolate has the high temp , and the surrounding has a room temp. So , the heat from the hot chocolate will dissipate into the surroundings and create a thermal equilibrium. So youre right.

The reaction in which hydrogen and oxygen are produced by running an electric current through water is an example of
Ainat [17]
Decomposition is the  example  of a  reaction  in  which  hydrogen and oxygen  are  produced  by  running   an  electric current  through  water.

 Decomposition  of   water through  electrolysis  of  water  into   oxygen  and hydrogen   gas  due  an electric  current  passed  through   water.   when an  electric  current  is passed through  water, oxygen   gas is being  produced  at  the anode  and  hydrogen  gas  is produced  at the  cathode.

Which of the following is the simplest ketone used as an organic solvent?
Lyrx [107]

Answer: Option (d) is the correct answer.

Explanation:

A ketone is an organic functional group that contains a carbon and oxygen atom bonded together through a double bond, that is, C=O.

For example, acetone CH_{3}-CO-CH_{3} is a ketone.

Whereas a hydrocodone is a drug which is used to relieve from moderate to sever pain.It is mostly combined with other drugs and resulting in a chemical formula C_{18}H_{21}NO_{3}.C_{4}H_{6}O_{6}.

A camphor is a volatile white color substance with chemical formula C_{10}H_{16}O. It has aromatic smell and its taste is bitter.

A menthone is also an organic compound with chemical formula C_{10}H_{18}O.

Thus, we can conclude that out of the given options the simplest ketone used as an organic solvent is acetone.

sukhopar [10]

Answer:

-255.4 kJ

Explanation:

The free energy of a reversible reaction can be calculated by:

ΔG = (ΔG° + RTlnQ)*n

Where R is the gas constant (8.314x10⁻³ kJ/mol.K), T is the temperature in K, n is the number of moles of the products (n =1), and Q is the reaction quotient, which is calculated based on the multiplication of partial pressures by the partial pressure of the products elevated by their coefficient divide by the multiplication of the partial pressure of the reactants elevated by their coefficients.

C₂H₂(g) + 2H₂(g) ⇄ C₂H₆(g)

Q = pC₂H₆/[pC₂H₂ * (pH₂)²]

Q = 0.261/[8.58*(3.06)²]

Q = 3.2487x10⁻³

ΔG = -241.2 + 8.314x10⁻³x298*ln(3.2487x10⁻³)

ΔG = -255.4 kJ
