a chemist measures 20.00 moles of water H2O . How many grams of water is that? PLS HELP WILL GIVE BRAINLIST

DedPeter [7]

Answer:

360.4 grams

Explanation:

The first step is to find the molecular mass of H2O. The molecular mass of a molecule is the atomic masses added altogether. Because there are 2 hydrogens, we need 2x the atomic mass. 2(1.01) + 1(16.00) = 18.02 amu.

The molar mass of H2O is 18.02 g/mol. This is the unit converter to change from moles to grams

$20.00 mol H2O *\frac{18.02 g H2O}{1 mol H2O} =360.4 g$

Answer:

D) the high specific heat of water caused by hydrogen bonding

Explanation:

The water has a higher specific heat and is due to the bonding of H2 molecules by the water. When the bonding is broken the heat is released and water molecules can move freely.

This leads to a decline in the temperatures and thus the heat is released in winters and coastal climates are considered to be milder than terrestrial climates. <u>As the energy is released on condensation</u>.

Which of the following represents gamma emission?

Tanzania [10]

Answer:

$_{28}^{60}\textrm{Ni}^*{\rightarrow }_{28}^{60}\textrm{Ni} +\gamma$

Explanation:

Gamma Emission :

When a nucleus is excited , it become unstable .To gain stability it comes back to lower energy state by emitting high-energy electromagnetic radiation .This radiation is called gamma radiation.

Symbol :

$\gamma$ : Gamma

<u>There is no change in mass number and atomic number during gamma emission</u>

In A,B,D mass number or atomic number has changed, So no Gamma emission take place.
