Answer:
The magnesium reacted with the oxygen in the air.
Explanation:
For argument’s sake, let’s say that the mass of magnesium oxide was 3 g and that of the oxide was 5 g.
The reaction was
magnesium + oxygen ⟶ magnesium oxide
Mass: 3 g 5 g
Mass of oxygen = 5 g – 3 g = 2 g
The 3 g of magnesium must have combined with 2 g of oxygen to form 5 g of magnesium oxide.
Not A because
2-Pentyne, an organic compound, is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne
Is B because
DescriptionPentenes are alkenes with chemical formula C ₅H ₁₀. Each contains one double bond within its molecular structure.
Answer:
Number 6 is correct all substances are made of molecules.
Explanation:
A molecule is a formation of atoms or a chemical and all substances are made of chemicals.
Yes, they will be able to make enough silver to fill the order. They possess more reactants than are necessary.
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.
<h3>More about silver nitrate</h3>
An inorganic substance with the chemical formula AgNO3 is called silver nitrate. It is coordinated in a trigonal planar structure when it is solid. It is frequently employed as a precursor to other compounds that include silver. As a staining agent for protein visibility in PAGE gels and scanning electron microscopy, it is utilized in the production of photographic films as well as in lab settings.
