Explanation: BMI(BODY MASS INDEX) is a very vital measurement tool for evaluating and the determining the level of Obesity of overweight of a person.
Body mass index is noninvasive, it is inexpensive and easy way of knowing how well the body weight and height is related to a person's well being.
It is calculated as follows; WEIGHT(KILOGRAMS)/SQUARE OF THE HEIGHT(METERS)
Answer:
(i) 1 moles of C
(ii) 4.5 moles of C
Explanation:
The Chemical equation is as follow,
A + 2 B → C
This chemical equation can be translated as;
(i) 1 mole of A reacts with 2 moles of B
(ii) 1 mole of A produces 1 mole of C
(iii) 2 moles of B reacts with 1 mole of A
(iv) 2 moles of B produces 1 mole of C
(v) 1 mole of C is produced by 1 mole of A and 2 moles of B
Therefore to find the number of moles of C produced by 2 mole of B we will do following proportional method.
As,
2 moles of B produced = 1 mole of C
So,
2 moles of B will produce = X moles of C
Solving for X,
X = 2 moles × 1 mole / 2 moles
X = 1 moles of C
Note:
In above problem the given moles were the same as that present in balance equation so incase if the moles are different from that of the equation then the method shown above can be used to solve it.
Lets try it for 9 moles of B:
As,
2 moles of B produced = 1 mole of C
So,
9 moles of B will produce = X moles of C
Solving for X,
X = 9 moles × 1 mole / 2 moles
X = 4.5 moles of C
Answer:
The correct answer is asthenosphere.
Explanation:
The Earth comprises four layers, that is, the crust, the mantle, the inner core, and the outer core. The magnetic field of the Earth is the amalgamation of the convection it attains from the Coriolis Effect and the outer core. The layer of the Earth where convection of the mantle takes place is the asthenosphere.
Traditionally, the term caviar refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (Beluga, Ossetra and Sevruga caviars). Depending on the country, caviar may also be used to describe the roe of other fish such as salmon, steelhead, trout, lumpfish, whitefish, carp, and other species of sturgeon.
