Answer:

'H' ion has only one proton and do not have any electron and neutron.

Explanation:

Hydrogen atom has only one electron and one proton and when it loses that electron, hydrogen ion (H+) is formed which is positively charged (charge of +1) and referred as a proton.

So, hydrogen ion do not left with any electrons or have zero electrons.

Hydrogen (H) atom do not have any neutrons in its tiny nucleus, so hydrogen ion (H+) also do not have neutrons.

Hence, 'H' ion (H+) has only proton and zero electron and neutron.

If 50 grams of CaCl2 is dissolved in 100g of water at 10 degrees. Is the solution saturated, unsaturated, or supersaturated?
Rashid [163]

Find solubility

  • Mass of solute/Mass of solvent×100
  • 50/100×100
  • 50%

So half amount of solute is dissolved .

Hence the solution is saturated

A 515cm^3 flask contains 0.460 g of a gas at a pressure of 153 kPa and a temperature of 322K. What is the molecular mass of this
erastovalidia [21]

Answer:

Molecular mass, M=28.89\ \text{g/mol}

Explanation:

Given that,

Mass of gas, m = 0.46 g

Volume of the container, V = 515 cm^3

Pressure, P = 153 kPa

Temperature, T = 322 K

We need to find the molecular mass of this gas. We know that,

PV =nRT

n = no of moles

n=\dfrac{PV}{RT}\\\\n=\dfrac{153\ kPa\times 0.515\ L}{8.31447\ LkPaK^{-1}{mol^{-1}}\times (322+273)\ K }\\\\n=0.01592\ \text{moles}

No of moles = mass/molecular mass

Let molecular mass is M

M=\dfrac{m}{n}\\\\M=\dfrac{0.46}{0.01592}\\\\M=28.89\ \text{g/mol}

So, the molecular mass of this gas is 28.89\ \text{g/mol}
