Answer:
+1
Explanation:
For the equation to be balanced, the total mass number and the total atomic number on both side of the equation but be equal.
This is illustrated:
For the mass number:
Left side: 22
Right side: 22 + 0 = 22
For the atomic number:
Left side: 11
Right side: 10 + x
11 = 10 + x
Collect like terms
x = 11 - 10
x = 1

Answer:
3.329 g
Explanation:
First you need to determine the molar mass of H2S which is 34.1 g/mol.
With that we know that to find the moles of H2S we just divide the mass of sample with the molar mass.
3.54 g / 34.1 g/mol = 0.103812317 mol of H2S
This means that there is also 0.103812317 mol of sulfur since there is 1 mole of sulfur per 1 mole of H2S.
The molar mass of sulfur is 32.065 g/mol and to find the mass of sulfur you need to multiply the molar mass with the moles of the compound.
0.103812317 mol * 32.065 g/mol = 3.329 g of sulfur
Let me know if you get something else or if something is unclear in the comments so that we can figure it out.
Answer:
the amount of air resistance depends upon the speed of the object, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
