Relate the law of conservation of mass to photosynthesis

The Law of Conservation of Mass holds true in photosynthesis
because the number of ______________

Answers

Answer:

moles of reactants is the same as the number of moles of products

Explanation:

Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight and water using energy from the sun. It is chemically symbolized as;

       6CO₂    +    6H₂O     →   C₆H₁₂O₆     +     6O₂

In the reaction above, the number of moles are balanced so as to comply with law of conservation of mass.

The law of conservation of mass states that "matter is neither created nor destroyed in the course of a chemical reaction but are simply transformed from one form to another".

Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects.

Answers

Answer:

Genetically modified organisms (GMOs) have altered their genomes in different ways in order to be resistant to both biotic (e.g., insect pests) and abiotic (e.g., drought) stress conditions

Explanation:

A genetically modified organism (GMO) is any organism, i.e., plant, animal, bacterium, etc., whose DNA has been altered by genetic engineering. The GMO crops can exhibit resistance to insect pests in order to increase their agronomic yields (as well as resistance to other biotic and abiotic stresses). It is for that reason that GMO crops are widely used in many countries. A commercially available GMO crop is Bt corn, which is a genetically engineered maize that expresses proteins from the bacterium Bacillus thuringiensis (Bt), which are poisonous to several insect pest species.

Why must you avoid breathing or coughing on an agar plate?

Answers

Answer:

Explanation:

An agar plate is simply a Petri dish and it contains agar as a solid growth medium. It also contains nutrients for the culturing of microorganisms. Because of this reason, we must avoid breathing and coughing on these agar plates to avoid contaminating them. If they get contaminated we won't only see microorganism growth that we want to see for the experiment or test but also all the organisms from our body.

I believe it is "A 15 lb. cat sitting 3 feet of the ground in the window"

Explanation:

I think it is  this one because it is one off the heaviest cats and it is this one because this 15 pound cat is higher than the other one. I hope you get an A

The cat that has the greatest gravitational potential energy is A. A 15 lb cat sitting 3 feet off the ground in a window.

Gravitational potential energy refers to the energy that is possessed by an object due to its position on the gravitational field.

Gravitational potential energy is also referred to as the potential energy that an object has in relation to a different object due to gravity. Therefore, the greatest gravitational potential energy will be the 15 lb cat sitting 3 feet off the ground in a window.

Answers

Answer:

C  Temperature at which the  mixture freezes

Explanation:

Measuring the temperature at which the mixture freezes provides a good way for the student to arrive at her conclusion.

The variable being tested for in this experiment is the freezing point of the water anti-freeze mixture. The dependent variable which is the freezing point is of prime concern. Amount of the antifreeze added is the independent variable. It is the cause of the phenomenon desired to be observed in the experiment.

There are different kinds of measurements. Measuring which of these variables will help her arrive at a conclusion is Temperature at which the  mixture freezes.

The act of Measuring the temperature at which the mixture freezes helps one to known or arrive at a conclusion. Note that the variable that is tested for in this experiment is the freezing point of the water anti-freeze mixture.

The temperature at which a substance freezes is referred to as its freezing point. Freezing point is also known to be the physical property of matter.

calculate the mass of 0.35 mole of copper (||) sulfate (CuSO4).

Answers

Ok so for finding mass we multiply mole by molar mass so our mole is 0.35 and our molar mass is Cu x 1 + S x 1 + O x 4 = 159.606
(Cu=63.54, S=32.06, O=16 )
So 159.606 x 0.35 = 55.8621 g

The mass of 0.35 mole of copper (||) sulfate (CuSO4) is found to be 55.86 g.

What is the mass of any substance?

The mass of any substance may be defined as a measure of the amount of matter in that particular substance. It is usually measured in grams (g) or kilograms (kg). Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it.

According to the question,

The mole of copper (||) sulfate (CuSO4) = 0.35 mole.

The molar mass of copper (||) sulfate (CuSO4) = 159.60.

∴ The mass of any substance is calculated by the given formula:

Molar mass × No. of moles.

        159.60 × 0.35 = 55.86 g.

Therefore, the mass of 0.35 mole of copper (||) sulfate (CuSO4) is found to be 55.86 g.
