Answer:
Are barium and chlorine a metal and nonmetal?
Explanation:
I had the same question, and my class reviewed the test and this was the answer to this question.
Redox reaction has a great economic impact. many product that we use in our daily lives are made using redox reaction. some of which are electroplating, that we use in our watches. and redox reaction also caused the rusting of irons, so buildings will rust and become brittle
Answer:
H3PO4 + 5 HCl → PCl5 + 4 H2O
Explanation:
The given equation is
H3PO4 + HCl = PCl5 + H2O
The above chemical equation has one P atom on both the sides, hence phosphorus is balanced
There are 5 Cl on the RHS but only one Cl on the LHS. On balancing the chlorine, we get -
H3PO4 + 5HCl = PCl5 + H2O
Now, there are 8 hydrogen atom on the LHS but only two on the RHS. On balancing the hydrogen on both the sides, the new equation become
H3PO4 + 5HCl = PCl5 + 4H2O
Let us check for oxygen
Oxygen on LHS = 4 and oxygen on RHS = 4
Thus, the balanced equation is H3PO4 + 5HCl = PCl5 + 4H2O

Answer:
Mass of carbon = 236.5 g
Explanation:
Given data:
Mass of C₃H₆ = 275 g
Mass of C = ?
Solution:
Formula:
Mass of carbon = molar mass of carbon/ molar mass of compound × mass of compound
Molar mass of carbon = 12 g/mol
Molar mass of compound = 42 g/mol
Mass of carbon = 36 g/mol / 42 g/mol × 275 g
Mass of carbon = 0.86 × 275 g
Mass of carbon = 236.5 g
