Answer:
Liquid
Explanation:
Gas is too far away, solid is close but it is not in a random pattern
Answer:
A gas made up of homonuclear diatomic molecules escapes through a pinhole .533 times as fast as Ne gas. Write the chemical formula of the gas.
Molar mass of Ne gas is 39.1 g/mol
.533= sqrt(39.1/x)
Sq (0.533) = 20.18/x
0.284 = 20.18/x
x = 71.034 g/mol
Where the chlorine has a molar mass of = 35.5g and molar mass of Cl2 gas = 2 × 35.5 = 71 g/mol
Explanation:
Graham's law: Rate1/Rate2 = sqrt(M2/M1) where M is the molar mass
Thus we have (Rate of x)/(Rate of Ne) = sqrt((Molar mass of Ne)/(Molar mass of x))
From the question (Rate of x)/(Rate of Ne) =0.533
and sqrt((Molar mass of Ne)/(Molar mass of x)) = sqrt(39.1/(Molar mass of x))
.533/1= sqrt(39.1/x)
Sq (0.533) = 20.18/x
0.284 = 20.18/x
x = 71.034 g/mol
Hence a compatible gas is chlorine Cl2 with molar mass of
71 g/mol
Answer:
2Cs+Sr(CrO4)-->Cs2(CrO4)+Sr
Explanation:
just set them equal, only value that changed was the amount of cesium(Cs)
The question is incomplete, the complete question is;
An unknown compound has the following chemical formula:
N2Ox
where x stands for a whole number.
Measurements also show that a certain sample of the unknown compound contains 3.7 mol of oxygen and 2.45 mol of nitrogen.
Write the complete chemical formula for the unknown compound.
Answer:
The complete formula of the compound is N2O3.
Explanation:
Given;
Number of moles of N = 2.45 moles
Number of moles of O = 3.7 moles
Chemical formula of unknown compound = N2Ox
From the ratio of the number of moles of N to O;
2/x = 2.45/3.7
2 * 3.7 = x * 2.45
x = 2 * 3.7/ 2.45
x =3
Hence the complete formula of the compound is N2O3.
A gas because if you freeze water, it turns into a shape as where gas can’t be frozen
