Answer:

answer 1

Explanation:

The law of conservation of energy establishes that the masses are not destroyed, they can only be transformed.

Therefore the mass of carbon in the reactants (CO2 and H2O) must be in the products (glucose and oxygen)

so the correct statement is the first

The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the products.

Answer:

The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in  the  products

Explanation:

The expression that best describes this reaction is that the same amount of carbon will be found in the reactants as in the products.

During the process of photosynthesis, carbon dioxide combines with water using solar energy to produce glucose and oxygen.

It can expressed as depicted below:

       6CO₂  +  6H₂O  →  C₆H₁₂O₆  + 6O₂

To validate our choice;

 This is a balanced chemical equation:

        6 moles of carbon is found on the reactant side and also, 6 mole of carbon on the product side.

But Glucose is not found on both sides of the expression

There are two N≡N bonds and three H–H  bonds are in reactants.

Given:

The reaction between nitrogen gas and hydrogen gas.

2N_2+3H_2\rightarrow 2NH_3

To find:

Bonds on the reactant side

Solution:

2N_2+3H_2\rightarrow 2NH_3

Reactants in the reaction = N_2, H_2

The bond between nitrogen atoms in single N_2 molecule  = N≡N (triple bond)

Then in two N_2  molecules = 2 N≡N (triple bonds)

The bond between hydrogen atoms in single H_2 molecule = H-H (single bond)

Then in three H_2  molecules = 3  H-H (single bonds)

Product in the reaction =NH_3

The bonds between nitrogen and hydrogen atoms in single NH_3 molecule = 3 N-H (single bond)

Then in two NH_3  molecules = 6  N-H (single bonds)

So, there are two N≡N bonds and three H–H bonds are in reactants.

When designing an engineering solution, certain criteria and constraints must be considered. Criteria are the features of the de
kondor19780726 [428]

Answer:

The criteria listed in order of importance are;

1) To be inflated in the event of a collision in order to protect the occupants of the front of the vehicle

2) To be able to withstand the load of the breaking force of the occupants in the front seat of the vehicle during a collision

3) To be relatively tough so as to resist being torn on impact with a sharp object

The constraints listed in order of importance are;

1) How is the model design able to sense a collision that requires the airbag to be inflated

2) The uncertainty of the load the airbag will withstand upon collision

3) The possible hazard that could be caused by the gas used to inflate the airbag

4) The usage/interaction tendency between the vehicle occupant and the airbag system

Explanation:

In order to produce an effective design, it is important to be able to foresee the possible deficiencies of an idea so as to be able to mitigate the problems before an actual incident happens.
