Answer:
oxygen, and hydrogen and carbon... those are all things that make up the elements.
Explanation:
n = m / M
Where, n is moles of the compound (mol), m is the mass of the compound (g) and M is the molar mass of the compound (g/mol)
Here, the given ethanol mass = 50.0 kg = 50.0 x 10³ g
Molar mass of the ethanol = (12 x 2 + 1x 6 + 1 x 16) g/mol
= 46 g/mol
Hence, moles in 50.0kg of ethanol = 50.0 x 10³ g / 46 g/mol
= 1086.96 mol
Answer:
Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.

Option C.When a neutral hydrogen atom loses an electron, a positively-charged
.
<h2>Explanation:
</h2>
- When a neutral hydrogen atom loses an electron a positively charged particle must remain.
- Proton is a positive charge of +1 e charge with a mass that is slightly less than that of a neutron.
- Ernest Rutherford discovered that a atom must have a concentrated positive charge at the center that contains most of the atom's mass. He stated that the nucleus contained a positive charge the proton. And the weight of a proton is 1837 times heavier than the weight of the electron.
Result: Losing of an electron by hydrogen lefts a positive charge i.e proton.
