Answer:
Ratio = 2 : 3 (Approx.)
Explanation:
Given:
Compound A = 1.278 g
Compound B = 1.904
Find:
Ratio
Computation:
Ratio = Compound A / Compound B
Ratio = 1.278 / 1.904
Ratio = 2 : 3 (Approx.)
In the reaction, fluorine and chlorine are present as reactants. Fluorine is a stronger oxidizing agent than chlorine, as fluorine has the tendency to be reduced. Keep in mind that oxidation is when there is an increase in the oxidation number of a substance and reduction is when there is a decrease in the oxidation number. Therefore, the correct statement becomes:
Cl- oxidizes to Cl and F reduces to F-.
C burning coal in a furnace
The correct answer in here is: Limited the burning of soft coal. Some reasons for that are that when Britain was the workshop of the world its coal consumption increased from around 10 million tons per annum in 1800 to almost 200 million tons in 1950 and also that <span>Coal smoke was linked to very high death rates from respiratory diseases such as bronchitis, killing between 800,000 and 1.4 million people in the period 1840-1900.</span>
