How many liters of water can be made from 34 grams of oxygen gas and 6.0 grams of hydrogen gas at STP?
At STP1mol O2 = 22.4L1mol O2 = 6.022 x 1023 molecules O222.4L O2 = 6.022 x 1023 molecules O2Convert liters O2 to moles O23.36L O2 X (6.022 x 1023 molecules O2/22.4L O2) = 9.03 x 1022 molecules O2
What number of moles of O2 is needed to produce 142 grams of P4O10 from P?
We first calculate the molar mass of P4O10, which is 284 g/mol. Then we convert the given mass of P4O10 (142 g) to moles using its molar mass. There is a 1:4 molar ratio between P4O10 and O2 in the reaction, so we multiply the moles of P4O10 by 4 to find the moles of O2 needed.
When 3.00 g of Mg is ignited in 2.20 g of pure oxygen what is the limiting reactant and what is the theoretical yield of MgO?
Moles Mg = 3.00 g / 24.312 g/mol =0.123 Moles O2 = 2.20 / 32 g/mol = 0.0688 2 Mg + O2 >> 2 MgO the ratio between Mg and O2 is 2 : 1 0.123 / 2 = 0.0615 moles O2 needed we have 0.0688 moles of O2 so O2 is in excess and Mg is the limiting reactant we get 0.123 moles of MgO => 0.123 mol x 40.31 g/mol =4.96 g
How many grams of Al2O3 are formed from 3 moles of O2?
If the reaction is just between O2 and Al, the balanced equation would be:3O2 + 4Al -> 2Al2O3By using the coefficients of the equation, we see that from 3 moles of O2 we get 2 moles of Al2O3. To find out how much this is in grams, we need to find the molar mass of Al2O3 . This is just the sum of the atomic masses of each atom that makes it up. (Use a periodic table to find atomic masses) So we get:26.98*2+16*3= 102.0One mole equals 102g, so the 2 moles produced by the reaction would amount to 204g.
What is the density of o2 at 1 ATM and 20 degrees celsius?
The density of O2 at 1 atm and 20 degrees Celsius is approximately 1.429 g/L.
What is Keq for the reaction 2SO2(g) O2(g) 2SO3(g)?
keq=[SO3]2[O2] [So3]2
Is the following equation balanced 2SO2 o2 2SO3?
No, the chemical equation is not balanced. The correct balanced equation is 2SO2 + O2 → 2SO3.
What will cause the formation of more products in the reaction 2SO2 plus O2 -- 2SO3?
adding SO2
Is 2SO2 plus O2 equals 2SO3 a combustion reaction Why or why not?
Yes, the reaction 2SO2 + O2 -> 2SO3 is a combustion reaction. This is because combustion reactions typically involve a fuel (SO2) reacting with oxygen (O2) to form a combustion product (SO3) with the release of heat and light energy.
Which equation represents the reaction of sulfur with oxygen to form sulfur trioxide?
SO2 + H20 --> H2SO3 sulphurous acid is not very stable though # The forest school, the forest school is wonderful the forest school is wonderful its filled with beer and Viagra the forest school is wonderful!!! #
How many atoms of s and o were present in the reaction 2so2 plus o2--2so3?
In the reaction 2SO2 + O2 → 2SO3, there are 4 atoms of sulfur (S) present on the left side and 4 atoms of sulfur on the right side. There are 6 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side.
which of the following is a decomposition reaction?
K2CO3 (s) → K2O (s) + CO2 (g)2SO3 (g) → 2SO2 (g) + O2 (g) CaCO3 (s) → CaO (s) + O2 (g)
What is the chemical breakdown in a decomposition reaction?
K2CO3 s -> K2O s plus CO2 g 2SO3 g -> 2SO2 g plus O2 g
What is a chemical equation that accurately represents what happens when sulfur and oxygen react to form sulfur trioxide?
The chemical equation for the reaction of sulfur and oxygen to form sulfur trioxide is: 2S + 3O2 -> 2SO3
How do you balance the equation SO2 plus O --- SO3?
Its balancing is very simple, 2SO2 + O2 = 2SO3
What is the molar ratio of 02 to so2?
The molar ratio of O2 to SO2 in the reaction 2SO2 + O2 -> 2SO3 is 1:1. This means that one mole of O2 reacts with two moles of SO2 to produce two moles of SO3.
What number of moles of o2(g) is required to react with 3.6 mole so2(g) in 2so2(g) o2(g) - 2so3(g)?
1,8 moles of oxygen are necessary.
