What are the reactants and products of cellular respiration and photosynthesis?

Svetlanka [38]

Cellular Respiration and photosynthesis require a source to create energy.

For Cellular Respiration, the reactants are nutrients (oxygen being the most common). This is then converted into energy stored in ATP.

Now there are many forms of Cellular Respiration, but to keep it vague, the reactants would be sugars, amino acids, and fatty acids and oxygen. These are broken down into similar but much more simple molecules the body can use for energy.

In the case of Photosynthesis, the reactant would be the sun's energy and carbon dioxide. This is then converted into energy for the plant as well as producing oxygen

1. Describe how SHAPE can change during a collision. Be specific with your evidence and add detail to your answer.

a_sh-v [17]

Answer:

Hey

of course, the damage of a collision depends upon how fast to objects are moving at each other and how strong they are. If you have two tanks moving at each other 2 miles per hour it will be very little damage and the ->shape<- will not change much, maybe a dint or two. But if two balloons filled with water are moving at each other 5000 mph they will completely evoporate in a burst of light, and their ->shape<- will change very much. This is how shape and motion are related.

Hope it helped

When of a certain molecular compound X are dissolved in of benzene , the freezing point of the solution is measured to be . Calc

puteri [66]

The question is incomplete. Here is the complete question.

When 2.10 g of a certain molecular compound X are dissolved in 65.0 g of benzene (C₆H₆), the freezing point of the solution is measured to be 3.5°C. Calculate the molar mass of X. If you need any additional information on benzene, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to 2 significant digits.

Answer: MM = 47.30 g/mol.

Explanation: There is a relationship between freezing point depression and molality. With this last one, is possible to calculate molar mass or molar weight of a compound.

Freezing Point Depression occurs when a solute is added to a solvent: the freezing point of the solvent decreases when a non-volatile solute is incremented.

Molality or molal concentration is a quantity of solute dissolved in a certain mass, in kg, of solvent. Its symbol is m and it's defined as

$m=\frac{moles(solute)}{kg(solvent)}$
