Explanation:
This reaction is in equilibrium and would hence obey lechatelier's principle. This principle states that whenever a system at equilibrium undergoes a change, it would react in way so as to annul that change.
Since it is an endothermic reaction, increasing the temperature would cause the reaction to shift towards the right.
This means that it favours product formation and more of the product would be formed.
Answer:
B. 0.13 M
Explanation: Because 1 mole of sulfuric acid reacts with 2 moles of potassium hydroxide, there are twice as many moles of KOH at the equivalence point as moles of H2SO4.
Answer:
It fills the container. Initially, in the small container, the gas had filled it with some amount of molecular space. When the container is made big, it arranges itself with more amount of molecular space filling the gas. Hence this happens when gas is transferred to a container.

Q. Which object is accelerating?
A: A skateboarder speeding up as he skates down a ramp.
The car is not accelerating as it is travelling at constant velocity. Acceleration refers to the rate of change of velocity of an object over time. Thus, there is no acceleration for the car.
The bicycle is not accelerating as it is decelerating (slowing down). This is not to be confused with accelerating in the opposite direction. Deceleration refers to the rate at which an object slows down. Deceleration is a scalar quantity whereas acceleration is a vector quantity. Yeah.
The final one isn't right, well, because the first two options are wrong.
So through process of elimination, you can deduce that the skateboarder experiences acceleration.
Also, the skateboarder experiences acceleration as he is "speeding up", implying that his speed is not constant and in fact increasing, so there's acceleration.
