For a second order reaction, the half-life is equal to:_____.
gtnhenbr [62]

Answer:

Half life = 1 / k[Ao]

Explanation:

From:

1/ [A] = kt + 1/ [Ao]

Isolating t on its own, we have:

kt = 1 / [A] - 1 / [Ao]

t = 1 / [Ao] / k

Re-arranging we have:

t = 1 / k [Ao]

The t represents the t=half life of the second order reaction and the formula can be re-written as:

t1/2 = 1 / k [Ao]

This is so because second order reaction decreases at a much faster rate than zero and first order reactions and there slopes decreases to zero at a much faster rate.

A substance intentionally added that affects the nature and quality of food is called.
VashaNatasha [74]

A substance intentionally added that affects the nature and quality of food is called food material.

There are seven most important components in food materials: carbohydrates, fats, proteins, vitamins, mineral salts, water and fibre.

Some other examples of food material:

1) Food dyes are chemical substances who gives artificial color to the food.

It is important to know which food dyes are in food because some dyes can cause allergic reactions or cancer.

2) Emulgators are used as an additive to food to emulsify some food.

Emulsions are two or more liquids that are normally not mixable. For example egg yolk and mayonnaise.

Can frozen ice transfer thermal energy to another substance? if so, how?
Studentka2010 [4]

Answer:

Matter can change state when thermal energy is transferred into or out of the substance. Ice melts and liquid water boils as thermal energy is added. Water vapor condenses and liquid water freezes as thermal energy is removed.
