Answer:
B) Stainless steel
Explanation:
Homogeneous mixture -
It refers to the composition of various substance , which leads to a mixture of complete uniform composition , i.e. , the ratio of each and every component of the mixture is constant all over the mixture , is referred to as a homogeneous mixture.
For example ,
In the solution of sugar and water , where 1 tablespoon of sugar is dissolved in 100 mL of water ,
The ratio of sugar and water remains constant all over the mixture.
Hence, from the given options the homogeneous mixture is B) Stainless steel .
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 and Explanation:
Ions are electrically charged particles that are formed from the removing and addition of electrons. It can be a positively or negatively charged atom.
