Mass of iron chloride (FeCl₂) : 22.68 g
<h3>Further explanation</h3>
Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements
In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison
With this law, we can calculate how many grams an element is needed to make a compound with a certain mass, as desired

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 bacterial endospores are microorganisms formed due to nutrient deprivation. These are placed first on a paper strip and not directly in the fermentation broth because these microorganisms are very resistance, thus, they need to adjust to the environment first before being acclimated to it.
Answer:
Five peaks
Explanation:
GaAs would show two peaks:
Ga-69 + As-75 = 144
Ga-71 + As-75 = 146
Their intensities are in the ratio 60 : 40 = 100:67.
Ga₂S₂ would show three peaks:
Ga-69 + Ga-69 + 2As-75 = (Ga-69)₂(As-75)₂ = 288
Ga-69 + Ga-71 + 2As-75 = (Ga-69)(Ga-71(As-75)₂ = 290
Ga-71 + Ga-71 + 2As-75 = (Ga-71)₂(As-75)₂ = 292
Their relative intensities are in the ratio
(60 + 40)² = 60² : 2×60×40 : 40² = 3600 : 4800 : 1600 = 75 : 100 : 33
A spectrum of a mixture of GaAs and Ga₂As₂ would show five peaks:
Two at m/e 144 and 146 with intensity ratios 100: 67 and
Three at m/e 288, 290, and 292 with intensity ratios 75:100 :33.
We cannot predict the absolute sizes of the peaks because we do not know the relative amounts of GaAs and GaAs₂.
