7.90x10^19 molecules of hydrogen gas are equal to how many moles of hydrogen gas? A)1.50 moles

B)0.000131 moles

C) 0..00230

D)4.76x10^43

Green is technically every other color but green but the other wavelengths of the other colors get absorbed by the object and the wavelength of the color green gets reflected

The answer is d- principle of faunal succession.

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
