Answer:
D
Explanation:
Since the state of matter is going from a gas to a solid, it would be going from a state of high entropy (greater disorder) to a state of lower entropy (less disorder).
Answer:
Number of protons is 9
Number of electrons is 9
Number of neutrons is 10
Explanation:
Atomic number refers to the number of protons or electrons in an atom, so the electrons and protons are 9.
Atomic mass is the sum of the number of protons and neutrons.
Therefore, there are 10 neutrons in the atom's nucleus
Answer:
4th Option
Explanation:
HNO3 is an acid, KOH is a base and they react to produce KNO3 which is a salt and H2O water.
So this reaction is a neutralisation reaction.
Answer : The correct option for blank 1 is, Shifts left.
The correct option for blank 2 is, Reverse.
Explanation :
According to the Le Chatelier's Principle, when the addition of the reactant in reaction system then the equilibrium will shift to the right (forward) direction of the reaction.
Or, if we remove the reactants from the reaction system then the equilibrium will be shifted to the left (backward) direction of the reaction. And simultaneously, there will be increase in the reverse reaction for the attainment of the equilibrium.
Answer:
3. doubles
Explanation:
for an ideal gas behavior, the relationship between volume and temperature is given by Charles law
Charles law states that the volume of a given mass of gas is directly proportional to its temperature provided that pressure remains constant. Mathematically, this is represented as
V ∝ T
V=KT
K = V/T
where V is the volume of the gas
T is the Temperature
k represents the constant of proportionality
For initial and final conditions of a gas,
= 
where 1 and 2 represent initial and final conditions respectively
therefore, T₁ = 100 and T₂ = 200
= 
200 × V₁ = 100 × V₂
divide both sides by 100
2V₁ = V₂
final volume,V₂ = 2V₁
there the volume doubles
