Its period 5 from 5s25p6, with Xenon(54) as the noble gas. 2+6 = 8 electrons
54+8 = 62, or Sm.
The first ionization energy of a known element is the energy
it needs to remove its highest energy or outermost electron. It is done to make
a neutral atom be a positively charged ion. The first ionization energy of neon
as a chemical equation is this:
Ne (g) -> Ne+ (g) + e-
<em>Answer:</em>
The order of liquid from top to bottom is as follow
<em>Explanation:</em>
Chart of densities:
- Red = 1.2 g/cm∧3
- Blue = 1.6 g/cm∧3
- green = 0.8 g/cm∧3
- Purple = 0.1 g/cm∧3
<em>Density: </em>
Density is the ratio of mass and volume as follow
d = m/v
<em>Summary:</em>
- Greater the density, it will be at bottom and vice versa.
- Blue liquid has greater density so it will be at bottom
- Purple liquid has low density, so it will be at top.
Answer:
A. Yes, there is more than enough sodium carbonate.
Explanation:
Hello,
In this case, based on the given reaction which is:
By stoichiometry, one computes the grams of sodium carbonate that will neutralize 1,665 g of sulfuric acid as shown below:
Thus, the available mass is 2.0 kg so 0.2 kg are in excess, therefore: A. Yes, there is more than enough sodium carbonate.
Best regards.
