D is the answer here look
Answer : The Product are the new substances that are created following a chemical reactions.
Explanation :
Chemical reaction : A chemical reaction occur when two or more reactants react to form a new substance.
Reactant : A substance that is involved in a chemical reaction.
Product : A new substance that is formed in a chemical reaction.
For example : 
In this, A and B are the reactants and AB is the product.
Therefore, the answer is Product.
Answer:
K= 25.16%
Mn= 34.59%
O= 40.25%
Explanation:
Find the total mass of the compound. You can do this by multiplying by the molar mass.
add them:
40+55+64=159g
Now convert each element individually to grams using molar mass
Divide by the mass of the compound and multiply by 100
Answer:
The bond angles between the axial bonding groups are slightly less than 180°.
The bond angles between the equatorial bonding groups are slightly less than 120°.
Explanation:
Accordign to VSEPR theory, a molecule with four bonding groups and one lone pair on the central atom has a trigonal bipyramidal electronic geometry.
The position of the lone pair can be located in the equatorial position or axial position.
When the lone pair is found in equatorial position, it has two axial groups that repel it and the angle of the lone pair between each axial group is 90°.
When the lone pair is in axial position it has 3 equatorial groups that repel it and the angle of the lone pair between each equatorial group is 90°.
Since the molecule has a lone pair, the most stable geometric structure is when the lone pair is in the equatorial position, because it has fewer repulsions than in the axial position.
The molecular geometry is "seesaw"
The bond angles between the axial bonding groups are slightly less than 180°.
The bond angles between the equatorial bonding groups are slightly less than 120°.
Respiratory is the answer since it’s the only one where you can breathe
