H2(g) + Cl2 (g) → 2HCl(g)
each mole of H2 produces two moles of HCl
moles of H2 needed ... 0.400 / 2
each mole of gas has a volume of 22.4 L
2Na(s) + 2HCl (aq) -> 2NaCl (aq) + H2 (g) 1. IF 2.5G OF SODIUM REACTS WITH AN EXCESS OF HYDROCHLORIC ACID, WHAT VOLUME OF HYDROGEN WILL BE PRODUCED? My working: Na H2 mass-2.5 0.109 mr-23 2 moles-0.109 0.543 volume 0.109 X 24000 = 2608.696cm3 Is that
Consider the reaction Mg +2HCl ------>MgCl2 + H2 What is the minimum amount of 1.85M HCl is necessary to produce 28.5L of H2 at STP Please help me work this problem
What volume of 0.1 M NaOH is required to neutralize 30 mL of 0.1 M HCl?
a mixture of 10cm3 of methane and 10cm3 of enthane was sparked with an excess of oxygen. after coolin to room temp, the residual gas was passed through aq KOH. what volume of gas was absorbed by the alkali ? Write the equations for CH4 + O2 and C2H6 + O2.
A mixture of chromium and zinc weighing .362 g was reacted with an excess of hydrochloric acid. After all the metals in the mixture reacted 225 mL of dry hydrogen gas was collected at 27 C and 750 torr. Determine the mass percent Zn in the metal sample.
a.)How many moles of NaOH are required to prepare 2.00L od 0.380M solution? answer is 0.760 mole of NaOH (mole/l * 2.00L) b.)What will be the molarity of a solution if 3.50 g of KOH are dissolved in water to make 150.0 mL of solution? answer is 0.52 M KOH
what is the theoretical mole ratio- NaCl to NaHCO3 How do you determine the percentage error of an experimental mole ratio It would be easier for us to help you if we had the entire problem instead of just parts of it. However, from the standpoint of Na,
What volume of hydrogen at STP is produced from the reaction of 50.0 g of Mg and the equivalent of 75g of HCl?
Zinc metal reacts with hydrochloric acid to produce hydrogen gas according to the equation below. What volume of hydrogen at STP is released when 15.1 grams of zinc react at STP? Zn(s) + 2HCl(aq) �¨ ZnCl2(aq) + H2(g)
Zn(s) + 2HCl(l) ZnCl2(s) + H2(g) at STP What mass of zinc is needed to produce 115 mL of hydrogen? - it's given 115 mL of hydrogen, so can convert to 115/1000/22,4 = 0.0051 moles H2 - the ratio between HCl and H2 is 2 : 1, so the moles of HCl needed
