8 0

In the PhET activity, “Properties of Gases”, when volume is kept the same, as the temperature is increased, the rate of collisions increases.

Explanation:

Gases have following three characteristic properties:

(1) Can be compressed easily.

(2) The containers are to be filled by expanding.

(3) More space is occupied than the liquids or solids.

According to the Property of gases in the PhET activity, at constant volume when the temperature of a gases increases, the rate of collisions increases.

Answer:

The $K_{m}$ of a substrate will be "10 μM".

Explanation:

The given values are:

$E_{t} = 20 \ nM$

$[Substract] = 40 \ \mu M$

$K_{cat}=600 \ s^{-1}$

Reaction velocity, $Vo=9.6 \ \mu M s^{-1}$

As we know,

⇒ $Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}$

On putting the estimated values, we get

⇒ $9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}$

⇒ $K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}$

⇒ $K_{m}+40=50$

On subtracting "40" from both sides, we get

⇒ $K_{m}+40-40=50-40$

⇒ $K_{m}=10 \ \mu M$

tatiyna

Answer:

Aldehydes
A hydrogen atom
Oxygen

Explanation:

Many tests to distinguish aldehydes and ketones involve the addition of an oxidant. Only aldehydes can be easily oxidized because there is a hydrogen atom next to the carbonyl and oxidation does not require oxygen

When monovalent cation (X) binds to divalent anion (Y) it will form

Romashka-Z-Leto [24]

When a monovalent cation X binds to a divalent anion Y, a compound with the formula $X_2Y$ would be formed.

A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be $X^+$

A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be $Y^2^-$

Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of $X^+$ would be required to successfully bind $Y^2^-$

$Y^2^-$ + $X^+$ + $X^+$ ----> $X_2Y$
