Answer:
- <u><em>It shifts left</em></u>
Explanation:
The<em> equilibrium</em> equation is:
By LeChatelier's principle when a <em>system</em> in <em>equilibrium</em> is disturbed, the system will react to counteract the disturbance and restore fhe equiibrium.
When one of the substances increases, look at where it appears in the chemical equilibrium equation and determine how that increase can be compensated.
In this case, the system will try to balance the increase in vapor, which is on the right side of the equation, by consuming part of it and producing more water and energy through the reverse reaction, from right to left. Thus, the system will shift left.
Answer:
D
Explanation:
The answer will be D because as we can deduct from the hypothesis, he will try to control the amount of food he gives the rats in order to see if in fact the fue of the mouse will be shinier
Answer:
The correct answer is - B. It measures the tendency of a radioisotope to decay radioactively.
Explanation:
The half-life of the radioactive sample is the time it takes to decay to its half amount of the unstable nuclei of its initial amount. It is radioactively decays to its half value or in simple words, it takes the time to decay an unstable nuclei to decay to its half value.
It can take milliseconds to million years to disintegrate the different unstable nuclei of a radioactive substance to disintegrate its half amount to a stable substance.
Answer: f. 2:2:2:1
Explanation: The reaction is a single displacement where Cs displaces H to pair up with OH.
The balance chemical equation is:
2 Cs + 2 H2O => 2 CsOH + H2
The number of atoms on both sides are equal.
Cs= 2
H= 4
O= 2
