Ne(g) effuses at a rate that is ______ times that of xe(g) under the same conditions.
Stels [109]
<span>The rate of effusion of a gas is inversely proportional to the square root of the molecular weight of the species. Now there will be differences among isotopomers but neglecting these and taking the avg mol wt of N2 = 28 and Xe = 132; Rate(N2)/Rate(Xe) = sqrt (132/28) = 2.17</span>

Fill in the chart to identify three parts of Dalton's model of the atom.
mamaluj [8]

The first part of Dalton's model is that all matter is made of atoms, and these atoms are indivisible.

The second part of this model is that atoms of an element have identical masses and identical propertes.

At last, the third part of Dalton's model is that all compounds are formed by two or more different type of atoms combined.

Calculate the amount (in grams) of kcl present in 75.0 ml of 2.10 m kcl
Lera25 [3.4K]
V = 75 mL = 0,075 L = 0,075 dm³
C = 2.1M
n = ?
---------------
C = n/V
n = C×V
n = 2.1×0,075
n = 0,1575 mol
--------
mKCl: 39+35.5 = 74,5 g/mol

74,5g --------- 1 mol
Xg ------------- 0,1575 mol
X = 74,5×0,1575
X = 11,73375g KCl
