Answer:Boron
Explanation:
it is element 5 represented by the letter B
The equilibrium relation allows us to find which statement is correct:
B) The balloon will shrink.
The stable equilibrium condition that the sum of forces in a system is zero
∑ F = 0
Where F is the force
Helium is a noble gas, which has a liquefaction temperature of 4.2K, therefore in almost all cases we find it in the gaseous state
The balloon is in an equilibrium between the outside atmospheric pressure and the pressure of the helium gas inside, when the temperature decreases the energy of the helium molecules decreases and has a lower speed, therefore creating a lower pressure inside, for therefore the balloon decreases its size until the pressures equalize.
Let's examine the claims
A) False. The balloon expands with increasing temperature
B) True. The balloon should contract until it equalizes the internal and external pressure
C) False. Helium gas becomes liquid at very low temperatures (4.2K)
D) False. One of the statements describes the process well
In conclusion the equilibrium relationship we can find which statement is correct:
B) The balloon will shrink.

The vapor of acetic acid will go to the floor of the room.
This is because the density of acetic acid vapor is equal to 2.07 is higher (almost twice) than the density of air which is equal to only 1
Answer:
According to Goog|e, "As the thumb is opposable, <u>it allows people to position it against other digits of the hand to manipulate or hold an object</u>. Some evidence suggests that this ability makes the thumb responsible for roughly 40% of the hand functions."

<u>Answer:</u> The excess reactant for the given reaction is 
<u>Explanation:</u>
Limiting reagent is defined as the reagent which is present in less amount and it limits the formation of products.
Excess reagent is defined as the reagent which is present in large amount.
For the given chemical reaction:
We are given:
Moles of calcium nitrate = 3.4 mol
Moles of lithium phosphate = 2.4 mol
By stoichiometry of the reaction:
3 moles of calcium nitrate reacts with 2 moles of lithium phosphate
So, 3.4 moles of calcium nitrate will react with = 
of lithium phosphate
As, the given amount of lithium phosphate is more than the required amount. So, it is considered as an excess reagent.
Thus, calcium nitrate is considered as the limiting reagent because it limits the formation of products.
Hence, the excess reactant for the given reaction is
