In chemistry for an chemical equation to be complete it has to be balanced using appropriate coefficients and state symbols such similar atoms are equal in both sides of the equation. The reaction between hydrogen sulphide and oxygen gas yields sulphur iv oxide and water as indicated by equation.
2H2S (g) + 3O2 (g) = 2SO2(g)+ 2H2O(l).
therefore the correct answer is 2,3,2,2
Answer:
= 0.613dm^3
Explanation:
Data:
Molarity, M = 1.50M
no. of moles = 0.920 moles
volume=?
Solution:
as, molarity= 
so, volume =
putting values:
= 
volume = 0.613dm^3
Answer:
A mol (approximately)represents the number 6.02 X 10^^23. Mols become useful when we learn that, for any element on the periodic table, 6.02 X 10^^23 atoms of that element have a mass equal to the atomic mass in grams. So, on the periodic table carbon has an atomic mass of 12.011. That means: 12.011 grams of carbon is made up of 6.02 X 10^^23 atoms.
The above question is tricky.
If the question considers 1 molecule of SO2 as a particle, then the answer is 1.80 * 6.02 X 10^^23
If the question considers the S as one particle, and the O2 as 2 more particles, then the answer is: 3 * 1.8 * 6.02 X 10^^23.

To dissolve in water, aluminum (Al) should form a compound with sulfate. Aluminum sulfate is the water soluble compound of aluminum. It has a chemical formula of Al2(SO4)3. It is used in industries as flocculating agent especially in the purification steps of drinking water and wastewater treatment plants.
Because they are made up of more than one type of atoms. The periodic table of elements are made up of all elements discovered. Elements are only one type of atom
