Answer: There are 1.53 moles present in molecules of water in a beaker.
Explanation:
According to the mole concept, there are molecules present in 1 mole of a substance.
So, number of moles present in molecules are calculated as follows.
Thus, we can conclude that there are 1.53 moles present in molecules of water in a beaker.
Answer: 1) The nuclide formed from the alpha decay of is
2) The nuclide formed from the beta-minus decay of is
Explanation:
1) For alpha-decay
In this process, alpha particle is released.
Equation follows:
The nuclide formed is
2) For beta-minus decay
In this process, a neutron is converted into a proton and an electron.
Equation follows:
The nuclide formed is
N2 + 3 H2 >> 2 NH3
moles NH3 = 11.50 g /17.0307 g/mol=0.6753
the ratio between H2 and NH3 is 3 : 2
moles H2 needed = 0.6753 x 3/2 =1.013
mass H2 = 1.013 mol x 2.106 g/mol=2.042 g
Answer: An air mass that originates over land in Central America is most likely<em><u> warm & dry.</u></em>
