Answer:
9.4 metric ton of SO₂ are emitted from yhe smoke stack each year.
Explanation:
Total amount = 100 metric ton
Sulphur in the total amount = 5% = 5 metric ton
Ash = 3% = 3 metric ton
Sulphur in the ash = 10% of 3 metric ton = 0.3 metric ton
Sulphur in the flue gases = 5 metric ton - 0.3 metric ton = 4.7 metric ton
Combustion of sulphur: S (s) + O₂ (g) → SO₂ (g)
32 g S _________ 64 g SO₂
4.7 x 10⁶ g ______ x
x = 9.4 x 10⁶ g = 9.4 metric ton of SO₂
In the nucleus. The nucleus is where the protons and the neutrons of the atoms are. Electrons are only have around 1/2000 of a proton's mass, so it is usually ignored
Think of it this way: it is a distribution problem in which you are multiplying the 2 on the outside with each element in the parentheses. Oxygen does not have a number in front of it, so put an imaginary one in front of it to help you. Do the same with Hydrogen since it doesn't have a number in front of it either. Now you know that hydrogen has one ion and oxygen has one... but you must now multiply each of the elements' ions by two. You should now know that Oxygen has 2 ions in Calcium Hydroxide and that there are also 2 ions of Hydrogen in Calcium Hydroxide. Does this make sense?
Answer:
.
Explanation:
-Synthesis reactions are reactions that appear when two distinct atoms or molecules engage to structure a specific molecule or compound. Most of the time, when a synthesis response occurs, electricity is launched and the response is exothermic. However, an endothermic consequence is additionally possible.
-A decomposition response starts offevolved from a single substance and produces extra than one substance; that is, it decomposes. One substance as a reactant and greater than one substance as the merchandise is the key attribute of a decomposition reaction. For example, in the decomposition of sodium hydrogen carbonate (also recognized as sodium bicarbonate)
-A single-replacement response (sometimes referred to as a single-displacement reaction) is a chemical response in which one aspect is substituted for every other factor in a compound, producing a new aspect and a new compound as merchandise
-A double-replacement response (sometimes referred to as a double-displacement reaction) takes place when components of two ionic compounds are exchanged, making two new compounds. A attribute of a double-replacement equation is that there are two compounds as reactants and two distinctive compounds as product
-A combustion response happens when a reactant combines with oxygen, many instances from the atmosphere, to produce oxides of all different factors as products; any nitrogen in the reactant is transformed to elemental nitrogen, N2. Many reactants, referred to as fuels, incorporate normally carbon and hydrogen atoms, reacting with oxygen to produce CO2 and H2O
