Answer: Volume of CO2 is 89127 mL
Explanation: The reaction that takes place is: C2H2 + O2 --> CO2 + H2O
The amount of C2H2 that react allow us to predict the amount of CO2 that will be obtained
26g/1mol is molar mass of C2H2 and 2/4 is the molar relation between CO2 and C2H2 in this reaction. Canceling units, at the end mol of CO2 are obtained
Now with the moles of CO2 and the ideal gases equation is possible to calculate the volumen occupied by the gas.
PV = RnT where P: pressure, V: volume, R: ideal gas constant, n: moles and T: temperature expressed in K (add 273,15 to °C temperature: 37,4°C + 273,15 = 310,55K)
V= RnT/P
To express volume in mL multiply the L result by 1000 which equals 89127 mL
The formula unit equation for the given reaction occurring in water is
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
<h3>What is chemical reaction?</h3>
Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.
When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)
Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.
Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

Answer:
Mass of each weight = 56.7 gram per piece
Explanation:
Given:
Lead’s density = 11.34 g/mL
Number of weights = 50
Volume of box = 250 mL
Find:
Mass of each weight
Computation:
Mass = volume x density
Mass = 250 x 11.34
Mass = 2,835 gram
Mass of each weight = Total Mass / Number of weights
Mass of each weight = 2,835 / 50
Mass of each weight = 56.7 gram per piece
I believe the answer is B
