Answer:
the answer would be c. plane
When the enthalpy change of the reaction is positive the reaction is endothermic
this means that the reaction is absorbing energy from the surrounding to the vessel
Answer:
The pH of a 4.4 M solution of boric acid is 4.3
Explanation:
at t=0 cM 0 0
at eqm
So dissociation constant will be:
Give c= 4.4 M and = ?
Putting in the values we get:
Also
Thus pH of a 4.4 M solution is 4.3
Answer:
A is a disturbance that transfers energy from one place to another. Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance.
Explanation:
The theory is most likely accurate and the main reason behind this process of thinking is because a majority of the scientists around the world agree with the theory. It can never be biased or incomplete. The correct option among all the options that are given in the question is the third option or option "C".
