Answer:

[Ar] 4s2

Explanation:

The noble gas that comes before Ca is Ar, so that's what you'll use for the noble-gas shorthand part of it. Ca has two additional electrons in the 4s orbital, hence the 4s2.

enyata [817]

The coefficients of the substances give you the ratio of the number of moles.
The 4 before the H2O and the 5 before the HCl tell you that for every 5 moles of HCl created, 4 moles of H2O had to react.

Therefore:
$(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl})$
can be used to find the moles of H2O that react.

$(3.45mol HCl)(\frac{4 mol H2O}{5 mol HCl}) = 2.76 mol H20$

Mariana [72]

The answer is true

Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light.The wavelength decreases as the light enters the medium and the light wave changes direction.
