Energy is stored in chemical bonds during photosynthesis.

During photosynthesis, the radiant energy from the sun is converted to chemical energy in carbohydrates.

Inorganic materials in the form of carbon dioxide and oxygen combine to form carbohydrates in the presence of radiant energy according to the equation below:

6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2

The energy is thus, stored in chemical bonds in the carbohydrate and this is what is oxidized during respiration to release the locked energy.

Answer:

it is the chlorplasts

Explanation:

Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts -- the energy factories found in plant cells.

The gases inside of a normal tire are usually measured when they are at ambient standard temperature (298 K) & under a contr
Anastaziya [24]

Answer:

100°C

Explanation:

The following were obtained from the question:

Initial temperature (T1) = 298 K

Initial pressure (P1) = 32.5 Psi

Final pressure (P2) = 40.68 Psi

Final temperature (T2) =..?

The final temperature can be obtained as follow:

P1/T1 = P2/T2

32.5/298 = 40.68/T2

Cross multiply to express in linear form

32.5 x T2 = 298 x 40.68

Divide both side by 32.5

T2 = (298 x 40.68) /32.5

T2 = 373K

Next, we shall convert 373K to celsius.

This is illustrated below:

T(°C) = T(K) – 273

T(K) = 373

T(°C) = 373 – 273

T(°C) = 100°C

Therefore, the temperature of the air inside the tire at 40.68 Psi is 100°C

Scientist A produces 83.67 g KMnO4 while Scientist B produces 81.35 g KMnO4.
noname [10]

Answer:

Y_A=92.1\%\\\\Y_B=89.6\%

Explanation:

Hello there!

In this case, according to the given chemical equation for the reaction for the production of potassium permanganate, we can see a 2:2 mole ratio of this product to the starting manganese (II) oxide, which means, we can calculate the theoretical yield of the former via stoichiometry:

m_{KMnO_4}=50.0gMnO_2*\frac{1molMnO_2}{86.94gMnO_2}*\frac{2molKMnO_4}{2molMnO_2}  *\frac{158.034gKMnO_4}{1molKMnO_4} \\\\m_{KMnO_4}=90.9gKMnO_4

Now, we are able to compute the percent yields, by using the actual yield each scientist got:

Y_A=\frac{83.67g}{90.9g} *100\%=92.1\%\\\\Y_B=\frac{81.35g}{90.9g} *100\%=89.6\%

Regards!

kupik [55]

Answer:

Hydrogen carbonate is an acid, sodium Sulfate is a salt.

Explanation:

Hydrogen carbonate is a weak acid because it will partially ionize in water while sodium sulfate is a neutral salt which is formed when neutralization of acid and base takes place

Explain why Cl2 can form two different Na bonds
I am Lyosha [343]

Answer: There is a single covalent bond in a chlorine molecule.

Explanation: The chlorine molecule is represented as Cl−Cl, i.e. C

l2. Between the chlorine atoms, 2 electrons overlap to form a region of high electron density to which the positively charged chlorine nuclei are attracted, such that internuclear repulsion is negated and a net attractive force results. Because the bonding electrons are shared between the nuclei, we conceive that each atom has 8 valence electrons.

Of course, on reaction with sodium, the sodium reduces the chlorine molecule to give 2×Cl−. The resultant bond between Na+ and Cl−is ionic and a non-molecular substance results.
