The correct answer is 3.Silver
Answer:
The answer to your question is: 0.118 moles of water
Explanation:
Data
moles of water = ?
Vol of O2= 1.6
Temp = 324°K
Pressure = 0.984 atm
R = 0.082 atm l / mol°K
Process
1.- Calculate the moles of O₂ using the ideal gas formula.
PV = nRT
n = 0.059 moles of oxygen
2.- Find the moles of water
2 moles of water ------------------ 1 mol of oxygen
x ------------------ 0.059 moles
x = (0.059 x 2) / 1
x = 0.118 moles of water
Answer:
Place the object in the graduated cylinder, and record the resulting water volume as "b." Subtract the volume of the water alone from the volume of the water plus the object. For instance, if "b" was 50 milliliters and "a" was 25 milliliters, the volume of the irregularly shaped object would be 25 milliliters.
Noble gas is very unreactive, it seldom form compound with other elements unless in extreme pressure and temperature. It is because noble gas has a stable duplet or octet of electron, it has low tendency to lose or gain electrons. Therefore it is very unreactive
Answer:
Explanation:
Hello there!
In this case, according to the given information and the chemical reaction, whereby iron and hydrochloric acid react in a 1:2 mole ratio, it is firstly necessary to calculate the moles of iron (II) chloride from each reactant in order to figure out the limiting reactant:
In such a way, we infer the maximum moles of FeCl2 product are yielded by HCl, for which it is the limiting reactant. Finally, we calculate the grams of product by using its molar mass as shown below:
