Answer:
Temperature on beans sprouted
Explanation:
- The variable amount is the amount that changes continuously.
- We calculate the sprout of the bean at which temperature it is sprouting rapid, in that case, the temperature acts as a variable amount.
Answer:
The equilibrium shifts to the right that is the forward reaction.
Explanation:
The chemical compound known as "Acetaminophen" is a chemical compound that is generally known to a layman as Paracetamol and it belongs to the drug class known as anagelsics which helps in the treatment of pain or say in the reduction of pain. Acetaminophen has the chemical Formula to be C8H9NO2, with the Molar mass of 151.163 g/mol and Boiling point of 420 °C.
The reaction between Acetaminophen and sodium methoxide gives methanol and acetaminophen sodium salt. Therefore, the acid base equilibrium reaction of these species is given as;
C8H9NO2 + CH3ONa <========> CH3OH + acetaminophen sodium salt.
The equilibrium shifts to the right that is the forward reaction.
Answer:

1. If the temperature of a gas is increased by 4x, its volume A. will increase by 4x.
2. If the pressure of a gas is decreased by 4x, its volume A. will increase by 4x.
<h3>
Explanation:</h3>
The combined gas law combines the three gas laws; Boyle's law, Charles law and Gay Lussac's law together relating pressure, temperature & volume and states thus:
"The ratio of product of Pressure and Volume to that of its Temperature is a constant."
In mathematical terms,
where P1, V1, T1 are the initial values and P2, V2, T2 the final values.
Therefore,
.......................................(1)
......................................(2)
1. If temperature of gas is increased by 4x, keeping pressure constant, from(1) since the volume of gas is directly proportional to its temperature (by Charles' law); it will increase in the same rate as the temperature is increased. Hence, the volume will increase by 4x.
2. If the pressure of a gas is decreased by 4x, keeping temperature constant, from (2), since the pressure of a gas is inversely in proportion to its volume (by Boyles' law), a decrease in pressure leads to increase in volume and vice versa. Hence, the volume will increase by 4x.
Answer:
C. 0.50 mol
Explanation:
Number of mole= mass /molar mass
Mass of KF is given as 29g
The molar mass of KF= 39+19= 58g/mol
No of mole= mass/ molar mass
= 29g/58g/mol
1/2 mol= 0.5 mol
