Answer:
The answer is "Option D".
Explanation:
The entire ionic equation for all the substances, which are ionic compounds but are available in an aquatic is represented in the form with ions in the full ionic equation.
In the Net ionic equation, it doesn't have the particulate matter throughout the net ionic equations throughout the equations.
In the Spectator ions, it doesn't participate in interactions mostly on reaction and the material hand. From both sides, the very same ions are present.
The evenly balanced chemical formula is,
It is the separate organic compound that full ion formula will match the choice D.
Answer:
4.06 × 10⁴ kg
Explanation:
Step 1: Given data
Mass (m): 44.8 ton
Step 2: Convert "m" to pounds
We will use the conversion factor 1 ton = 2,000 lb
.
44.8 ton × (2,000 lb/1 ton) = 8.96 × 10⁴ lb
Step 3: Convert "m" to grams
We will use the conversion factor 1 lb = 453.59 g.
8.96 × 10⁴ lb × (453.59 g/1 lb) = 4.06 × 10⁷ g
Step 4: Convert "m" to kilograms
We will use the conversion factor 1 kg = 1,000 g.
4.06 × 10⁷ g × (1 kg/1,000 g) = 4.06 × 10⁴ kg
Answer: 75.7 % yield
Explanation:
The balanced chemical equation is:
According to stoichiometry :
68.2 g of 
will require = 64 g of 
Thus 7.5 g of will require = 
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 68.2 g of give = 96 g of
Thus 7.5 g of give =
of 
% yield=
Thus 75.7 % yield is there.
