Answer: 21.5
Explanation: BMI is the value that is calculated for attaining the toatal fat in a body.
Given units are,
Weight of individual=150 lbs(pounds)
Height of individual=70 inches
BMI index formula in terms of pounds and inches is:-
BMI = (Weight in Pounds / (Height in inches) x (Height in inches)) x 703
BMI=(150 lbs/(70 inches)×(70 inches))×703
<u>BMI=21.5</u>
The right answer is D.
Intermolecular forces lead to the assembly of microscopic systems. They are responsible for the cohesion of matter in most macroscopic phases. These are weak forces compared to covalent bond strengths. They do not modify the nature of the molecular species and only influence their mode of assembly. The most well-known intermolecular bonds are the Van der Waals bond and the hydrogen bond.
The greater the intermolecular forces, the more the aspect of the element will tend to be more condensed (gas <liquid <solid).
Explanation:
the first one and the last one is transverse
Answer:
element Y and Z
Explanation:
Having on valence electron indicates that these elements are on the same column/group of the periodic table. Both these elements will bond with a -1 charge.
