The modern model of the atom B)

I am thinking the answer is B. I think this because Bohr had a model similar, but his was lacking the cloud of electrons. His just had electrons orbiting the nucleus. 
I hope this is right!<span />

In the equation 2K+ 2H2O ---&gt; 2KOH +H2
Law Incorporation [45]

 The much hydrogen that is  produced   is 0.02 mol  of H₂ (answer  B)

 Explanation

2K +2H₂O→ 2 KOH + H₂

 Use the mole ratio to determine the moles of H₂

 From equation above the  K :H₂  is  2:1

Therefore the moles of H₂ = 0.04 x 1/2 = 0.02  mol  of H₂

A chemistry student needs 60.0 ml of ethanolamine for an experiment. By consulting the CRC Handbook of Chemistry and Physics, th
BARSIC [14]

Answer:

The student should weigh out 61.2g of ethanolamine [6.12 * 10]

Explanation:

In this question, we are expected to calculate the mass of ethanolamine needed to make 60.0ml of it given that the density of the ethanolamine in question is 1.02g/cm^3

Mathematically, it has been shown that mass = density * volume

Hence, by multiplying the density by the volume, we get the mass.

Now, from the question we can see that we have the values for the density and the volume. We now need to get the mass.

Since cm^3 is same as ml, we need not perform any conversion.

Hence, the needed mass is:

60 * 1.02 = 61.2g
