Balloon X is filled with the carbon monoxide. Balloon Y is filled to the same volume with carbon dioxide. The balloons are left
weqwewe [10]

Answer:

The smallest ballon is the ballon X

Explanation:

It is possible to answer this question by using Graham's law:

\frac{v_1}{v_2} =\sqrt{\frac{MW_2}{MW_1}}

Where v is the speed of effusion and MW is molar weight of each compound.

This equation is showing that speed is inversely related to the square root of its molar mass. As carbon dioxide has a bigger MW than carbon monoxide, the speed of effusion of carbon dioxide is lower doing its ballon biggest than carbon monoxide ballon, thus: <em>The smallest ballon is the ballon X</em>

unknown element x has a mass number of 88 and contains 50 neutrons in the atom. element x is strontium
AnnyKZ [126]

Strontium element has a mass number of 88 and contains 50 neutrons in the atom.

Given that;

Mass number of element X = 88

Number of Neutrons in element X = 50

we know the concept that Mass number is represent as total number of Neutrons and proton present in Nucleus

So, Mass number of element X = Number of Neutrons in element X + Number of Protons in element X

Thus, 88 = 50 + Number of Protons in element X

Number of Protons in element X = 38

As, Number of proton = Atomic number

So, Atomic number of element X = 38

Hence Unknown Element X is Strontium
