Answer:
Adding more of gas C to the system
Explanation:
- <em>Le Châtelier's principle</em><em> states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.</em>
1) Adding more of gas C to the system:
Adding more C gas will increase the concentration of the products side. So, the reaction will be shifted to the left to attain the equilibrium again.
2) Heating the system:
Heating the system will increase the concentration of the reactants side as the reaction is endothermic. so, the reaction will be shifted to the right to attain the equilibrium again.
3) Increasing the volume:
has no effect since the no. of moles of gases is the same in both reactants and products sides.
4) Removing some of gas C from the system:
Removing some of gas C from the system will decrease the concentration of the products side. So, the reaction will be shifted to the right to attain the equilibrium again.
<em>So, the right choice is: Adding more of gas C to the system.</em>

Answer:
See below
Explanation:
The electoral college ensures that the most populated states can't always pick the next president. States that have the most population would be able to skew the elections by cancelling out several other less populated state's voters. One large city could cancel out every vote from the state of Rhode Island.
With the electoral college, each state has a given number of votes to cast for a president. Some states can split their college votes while others cast all votes for the same candidate.
If you look at Pennsylvania in 2020 as an example, they have 20 electoral votes. Pennsylvania does not split their votes so all go to just one candidate. In the measurement of votes, it might show that candidate A got 51% of the votes and candidate B got 49%. The 20 electoral votes would all go to candidate A and candidate B gets nothing. Candidate B may have gotten millions of individual votes within the state but that no longer matters. Candidate A won the state so gets all 20 electoral votes. If the country went by the individual vote, Candidate B would keep all those votes he got from the 2 or 3 large cities in Pennsylvania.
It would be easy to see that if you only counted the individual votes (called the popular vote), a candidate could compile more votes from all of the states even though the candidate did not win that state by the majority vote. The electoral college makes sure that a candidate cannot carry those votes from the state that they lost.
If elections were based on this popular vote, then most of the states with small populations would barely affect the outcome of an election. The popularity vote would ensure that the states with the largest populated cities would always control who gets elected.
It would especially be detrimental in todays age since most large cities are almost always voting for just one party.
I hate to tell you this but this isnt tinder hunny
Answer:
(C) Mass of KCl(s), mass of H20, initial temperature of the water, and final temperature of the solution
Explanation:
molar enthalpy of solution of KCl(s) is heat evolved or absorbed when one mole of KCl is dissolved in water to make pure solution . The heat evolved or absorbed can be calculated by the following relation.
Q = msΔt where m is mass of solution or water , s is specific heat and Δt is change in temperature of water .
So data required is mass of water or solution , initial and final temperature of solution , specific heat of water is known .
Now to know molar heat , we require mass of solute or KCl dissolved to know heat heat absorbed or evolved by dissolution of one mole of solute .
The downward or upward curve at the surface of liquid in a container is said to be the meniscus of the liquid, which occurs due to the surface tension. This curve can be concave or convex depending on how the molecules of liquid interact with surface of the container. The reading of the meniscus should always be done at the eye-level.
When the particles of the liquid are more attracted to the container than to each other then a concave meniscus occurs whereas when the particles of the liquid are more attracted to each other than to the container then a convex meniscus occurs.
The bottom of the curve will be read for a concave meniscus and for convex meniscus, the top of the curve gives the correct reading of the volume of liquid.
