Answer: 15.62 moles of 
are needed to produce 250.0 g of 
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of is produced from decomposition of = 2 moles of
Thus 7.812 moles of will be produced from decomposition of =
of
Thus 15.62 moles of are needed to produce 250.0 g of
Answer:
because high intermolecular fotce
Answer:
the functional group in ethyl alcohol is :OH(hydroxyl group)
Explanation:
the principle of solubility or miscibility is :''like dissolves like'' which means compounds that are similar dissolves each other,Ethanol or ethyl alcohol mixes or interacts with water by forming hydrogen bond with water,since both water and ethyl alcohol are polar compounds.
The answer is A
explanation:
We know that the atomic weight of carbon is 12 grams and that of oxygen is 16 grams. Hence we have calculated the mass 5 of carbon in carbon dioxide to be 27.27%.
1. Find moles! In this case, since we are dealing with H2 gas, we will be using PV=nRT (Where P is pressure, V is volume in liters, n is moles, R is the gas constant specific for the pressure unit and T is temp in Kelvin).
(0.951 atm)(3.22L)=n(.082057)(373K)
3.062=30.607n n=0.100 moles H2
Mn (s) +HCl (g)--> H2 (g)+ Mn(Cl#)
The ratio of HCl to H2 must be 2:1 (Although we do not know the exact number, the ratio must be that so the actual equation can be balanced)
0.100 moles H2* (2 mol HCl/1molH2)=0.200 moles HCl
0.200 moles HCl * (1mol Cl-/1molHCl)=0.200 moles of chlorine
2. Find moles of manganese
2.747g Mn * (1 mol Mn/54.938g Mn)=0.05000 moles Mn
3. Mole Ratio
0.05000 moles Mn/0.200 moles chlorine=0.25 (A ratio of 1/4)
The formula should be MnCl₄
