Answer: The given element has 8 protons and 8 neutrons in it.

Explanation:

General representation in writing an element is given by: $_{Z}^{A}\textrm{X}$

where, X denotes the element

Z denotes the atomic number

A denotes the atomic mass

We know that:

Atomic number = Number of electrons = Number of protons

And, Atomic mass = Number of protons + Number of neutrons ....(1)

In the given element: $_8^{16}\textrm{O}$

Z = 8 which means number of protons = 8

A = 16

Putting A = 16 in Equation 1, we get:

16 = 8 + Number of neutrons

Number of neutrons = 16 - 8 = 8

Hence, the given element has 8 protons and 8 neutrons in it.

Oxygen-16 atomic number is 8 so it has 8 protons. Its atomic weight is 16 so 16-8 = 8 neutrons.

Hope I helped. :)

One thing that does not change is the chemical composition of water, which is still H2O. And maybe mass, if all of the particles remain inside the beaker, which was never mentioned in the question so I am not sure.

A sample of argon gas (molar mass 40 g) is at four times the absolute temperature of a sample of hydrogen gas (molar mass 2 g).

katen-ka-za [31]

Answer:

Ratio of Vrms of argon to Vrms of hydrogen = 0.316 : 1

Explanation:

The root-mean-square speed measures the average speed of particles in a gas, and is given by the following formula:

Vrms = $\sqrt{3RT/M}$

where R is molar gas constant = 8.3145 J/K.mol, T is temperature in kelvin, M is molar mass of gas in Kg/mol

For argon, M = 40/1000 Kg/mol = 0.04 Kg/mol, T = 4T , R = R

Vrms = √(3 * R *4T)/0.04 = √300RT

For hydrogen; M = 1/1000 Kg/mol = 0.001 Kg/mol, T = T, R = R

Vrms = √(3 * R *T)/0.001 = √3000RT

Ratio of Vrms of argon to that of hydrogen = √300RT / √3000RT = 0.316

Ratio of Vrms of argon to that of hydrogen = 0.316 : 1

What should be the mole fraction of O2 in the gas mixture the diver breathes in order to have the same partial pressure of oxyge

Nutka1998 [239]

The question is incomplete, here is the complete question:

A scuba diver is at a depth of 355 m, where the pressure is 36.5 atm.

What should be the mole fraction of $O_2$ in the gas mixture the diver breathes in order to have the same partial pressure of oxygen in his lungs as he would at sea level? Note that the mole fraction of oxygen at sea level is 0.209.
