This is because 4s orbital is less in energy than that of 3d
Answer:
Explanation:
<u>1) Find the z-scores:</u>
a) z-score for 22.6 inches length
- z = [ 22.6 - 20 ] / 2.6 = 1.00
b) z-score for 17.4 inches length
- z = [ 17.4 - 20 ] / 2.6 = - 1.00
<u>2) Probability</u>
Then, you have to find the probability that the length of an infant is between - 1.00 and 1.00 standards deviations (σ) from the mean (μ).
That is a well known value of 68%, which is part of the 68-95-99.7 empirical rule.
The most exact result is obtained from tables and is 68.26%:
- 1 - P (z ≥ 1.00) - P (z ≤ - 1.00) = 1 - 0.1587 - 0.1587 = 0.6826 = 68.26%
Answer:
C. An atom consists of positively charged matter that contains negatively charged particles.
Explanation:
Yes, a mixture could be made up of only elements and no compounds, given that the elements never undergo a chemical interaction and stay only in physical contact with each other.
Answer:
Two of the three salts are soluble.
One of the three salts is soluble.
Explanation:
<em>One or two of the three salts would be soluble in water depending on if the water is cold or hot.</em>
<u>According to the solubility rules of chloride salts, all chlorides are soluble in cold water except for those of silver (Ag), lead (Pb), and mercury (I) (Hg). </u>
This thus means that both AgCl and would be insoluble in cold water while LiCl would be soluble.
is, however soluble in hot water.
Hence, in cold water, one of the three salts (LiCl) would be soluble, while in hot water, two of the three salts (LiCl and ) would be soluble.
