Answer:
Yes. Since they have more than the required reactants.
Explanation:
Zinc reduces silver nitrate to silver metal according to the following equation.
2AgNO₃ + Zn → 2Ag + Zn(NO₃)₂
From the equation 2 moles of AgNO₃ produce 2 moles of silver.
If we consider the zinc to be used number of moles=mass/RAM
RAM of zinc =65.38
No. of moles=500/65.38
=7.6476moles
To produce 800 grams of silver they require:
800/107.868 moles=7.4165 moles of silver nitrate since the ratio of silver nitrate to silver produced is 1:1
The number of moles of silver nitrate available=1500/169.872
=8.83 moles.
As the amount of reactants available is more than the required the company will make it in producing the 800 grams of silver required.
Answer:
Empirical formula is C₂H₆O.
Explanation:
Empirical formula:
It is the simplest formula gives the ratio of atoms of different elements in small whole number
Given data:
Percentage of hydrogen = 13.3%
Percentage of carbon = 52.0%
Percentage of oxygen = 34.7%
Empirical formula = ?
Molecular formula = ?
Solution:
Number of gram atoms of H = 13.3 / 1.01 = 13
.17
Number of gram atoms of O = 34.7 / 16 = 2.17
Number of gram atoms of C = 52.0 / 12 = 4.3
Atomic ratio:
C : H : O
4.3/2.17 : 13.17/2.17 : 2.17/2.17
2 : 6 : 1
C : H : O = 2 : 6 : 1
Empirical formula is C₂H₆O.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
n = 46 / 158
The relative molecular mass of compound is not correct.
Answer:
nitrogen is the answer because of the same position of group in periodic table
Answer:
.96875 moles
Explanation:
22.4 liters per mole at STP for a gas
21.7 / 22.4 = .96875 moles
S + 2e⁻ → S²⁻ (sulfur will gain electrons)
Mg - 2e⁻ → Mg²⁺ (magnesium will lose electrons)
Magnesium is a metal which tends to give electrons which are received by the sulfur, which is a nonmetal and tends to gain electrons.
