Explanation:
To balance a chemical equation implies that we are conserving the number and mass of the reacting species.
Chemical equations must obey the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".
This suggests that mass is conserved.
The number of atoms on the reactant side must be equal to that on the product end.
Before proceeding, check the species to see if they have equal number of atoms on both sides:
Fe + CuCI₂ → FeCI₂ + Cu
Elements reactants products
Fe 1 1
Cu 1 1
Cl 2 2
We can see that the equation is already balanced

Answer:
v2=40.35L
Explanation:
p1v1/t1=p2v2/t2
v2=t2p1v1/t1p2
v2=984*760*22.4/273.15*1520
v2=40.35 L
Answer:
2.7 g/cm³
Explanation:
Step 1: Calculate the mass of kerosene
The mass of the full beaker (mFB) is equal to the sum of the masses of the empty beaker (mEB) and the mass of the kerosene (mK).
mFB = mEB + mK
mK = mFB - mEB
mK = 60 g - 20 g = 40 g
Step 2: Calculate the density of kerosene
Density (ρ) is an intrinsic property of matter. It can be calculated as the quotient between the mass of kerosene and its volume.
ρ = m/V
ρ = 40 g/15 cm³ = 2.7 g/cm³
