Answer:
b 1 mole of nitrogen 6 hydro 1 sulfur
Answer:
Option (e) should be discarded.
Explanation:
The given set of data is said to be precise if the values are close to each other. In this problem, a chemistry student is experimentally determining the boiling point of bromine.
In this case, all values are close to each other but option (e) i.e. 56.3° should be discarded to make his data precise.
Answer:
<h2>251 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 0.251 × 1000
We have the final answer as
<h3>251 g</h3>
Hope this helps you
Balancing the equation, we get:
2C₂H₆O + O₂ → 2C₂H₄O₂ + 2H₂O
So
α = 2
β = 1
γ = 2
δ = 2
