Which reaction occurs when equivalent quantities of H" (or H30) and OH" are mixed?
Lynna [10]

Answer: A reaction which occurs when equivalent quantities of H" (or H_{3}O^{+}) and OH" are mixed is a neutralization reaction.

Explanation:

When acid and base chemically combine together to form sat and water then it is know as neutralization reaction.

An acidic substance gives hydrogen ions (H^{+}) on dissociation and a basic substance gives hydroxide ions (OH^{-}) on dissociation.

For example, H^{+} + OH^{-} \rightarrow H_{2}O is a neutralization reaction where an acid and base are mixed together to form water.

No salt is formed as because here the reactants are not present as compounds.

In a hydrolysis reaction, water molecule(s) is added to the reactant molecules.

For example, CH_{3}COOCH_{3} + H_2O \rightarrow CH_{3}COOH + CH_{3}OH

Oxidation is the process of addition of oxygen to a molecule and removal of hydrogen.

Reduction is the process of addition of hydrogen in a compound and the removal of oxygen atom.

Therefore, we can conclude that reaction which occurs when equivalent quantities of H" (or H_{3}O^{+}) and OH" are mixed is a neutralization reaction.

There’s a part two for this but I can’t fit it all in this image, if you know how to do this please help me out. I’m stuck on th
Alina [70]

Answer:

See explanation

Explanation:

According to the law of conservation of mass; the total mass of reactants on the left hand side of the reaction equation is equal to the total mass of products on the right hand side of the reaction equation.

Hence, the total mass of each atom on either side of the reaction equation should be exactly the same.

Since there are two atoms of oxygen on the reactants side, the total mass of oxygen = 16 amu * 2 = 32 amu

Since there are two oxygen atoms on the products side, total mass of oxygen = 16 amu * 2 = 32 amu

How does mechanical advantage help in doing work?
Lostsunrise [7]

Answer:

  • Mechanical advantages allows humans to perform tasks much easier in terms of the force they need to apply, but must always obey the conservation of energy.

  • Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys.

  • A good example is pushing a heavy object up a ramp. It may be easier to push the object up a ramp instead of just lifting it up to the right height, but it takes a longer distance.
