Answer:
Explanation:
Hello,
In this case, considering the given two reactions, when we add them, we obtain:
Thus, we can simplify both hydrochloric acid and calcium chloride as they are both sides to obtain:
Best regards.
The balanced chemical equation Lead IV oxide decomposes
to yield lead II oxide and a colorless gas is
Pb3O4 → 3PbO + 1/2O2(g). The key in the balancing of
chemical reaction is to make sure that you got the exact chemical formula of
the substance that is reacting and the yielded product. After getting the
formula, identify first the hardest element/atom to be balanced such as Na, Zn,
Cl, etc. Then proceed to the easier ones such as O, H. Make sure to not the
atoms present in the molecule of the substance.
Answer:
Explanation: The main difference between Genetic and Hereditary Diseases is that genetic disease is a condition which occurs due to an abnormality in the individual’s genome while a hereditary disease is a condition caused by a mutation of a gene which can be characteristically transmitted from one generation to another, also The main difference between these two terms lies in the fact that hereditary diseases have the potential of being carried from one generation to another whereas a genetic disease can either be hereditary or not, but there will always be a mutational change in the genome.
Answer:
Mass of iodine = 1954.26 g
Explanation:
Given data:
Mass of chlorine react = 546 g
Mass of iodine produced = ?
Solution:
Chemical equation:
2NaI + Cl₂ → 2NaCl + I₂
Number of moles of chlorine:
Number of moles = mass/molar mass
Number of moles = 546 g/71 g/mol
Number of moles = 7.7 mol
Now we will compare the moles of chlorine with iodine.
Cl₂ : I₂
1 : 1
7.7 : 7.7
Mass of iodine:
Mass = number of moles × molar mass
Mass = 7.7 mol × 253.8 g/mol
Mass = 1954.26 g
