The formula or chemical formula of a compound is same irrespective of source / mode of synthesis . Thus if a sample of compound has one carbon atom for every two atoms of oxygen (CO2), the formula will remains the same
So the answer is that for all other samples the compound X should hold this ration true.
Answer:
C
Explanation:
The substance would be classified as neutral, so C.
Answer:
Mass of Na₂CrO₄ = 5.75 g
Explanation:
First of all we will write the balance chemical equation.
2AgNO₃ + Na₂CrO₄ → Ag₂CrO₄ + 2NaNO₃
Now we will calculate the moles of AgNO₃.
Number of moles = mass / molar mass
Molar mass of AgNO₃ = 107.87 + 14 + 3× 16 = 169.87 g/mol
Number of moles = mass / molar mass
Number of moles = 12.1 g / 169.87 g/mol = 0.071 mol
Now we will compare the moles of AgNO₃ and Na₂CrO₄ from balance chemical equation.
AgNO₃ : Na₂CrO₄
2 : 1
0.071 : 1/2× 0.071 = 0.0355
Now we will calculate the mass of Na₂CrO₄.
Molar mass of Na₂CrO₄ = 23×2 + 52 + 16×4 = 162 g/mol
Mass of Na₂CrO₄ = number of moles × molar mass
Mass of Na₂CrO₄ = 0.0355 mol × 162 g/mol
Mass of Na₂CrO₄ = 5.75 g
Answer: 35.4 g
2 moles of phosphorous chloride are produced by = 3 moles of
Thus 0.37 moles of phosphorous chloride are produced by= of
Mass of
Thus 35.4 g of chlorine reacted with the phosphorus
