Answer: The empirical formula will be=
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= (100-11) = 89 g
Mass of H = 11 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of H =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For H =
The ratio of C : H: = 1: 1.5
Convertig them into whole number ratios
The ratio of C : H: = 2: 3
Hence the empirical formula is
The empirical formula will be=
Answer : The correct option is, (D)
Explanation :
Balanced reaction : Balanced reactions are those reactions when the number of different atoms of the element present in the reactant sides is equal to the product sides.
The given unbalanced reaction is,
The balanced chemical reaction is,
Therefore, 1, 1, 2, 1 are the coefficients that would correctly balance this equation.
Answer:
Instead, pour a small amount into a beaker or clean weigh dish. Once you have added a chemical to a container, label it promptly. When you are finished with the experiment, dispose of the excess chemical as chemical waste. Do not simply pour the excess chemical down the sink.
