The testing of the acidities of the compounds to determine the combination that will keep the drug intact before it reaches the intestines is a part of EXPERIMENTATION process. The experimentation is done in order to prove or answer different queries that were raised during the hypothesis making.
Answer:
NaI
Explanation:
Sodium has a charge of 1+ and iodine has a charge of 1-. They exist in a one-to-one ratio. Because they are ionic compounds, they go for the lowest ratio available.
Elements are made of only one kind of atom. The molecule is made up of two or more kinds of atoms. There is no physical change that can separate the compounds into more than one kind of substance. This makes a compound a pure substance.
To compute for grams of fat in each salad:
We know that, A = C.
And B is 5 grams more, so it is B = 5 + A
And the total fat is 65, so A + B + C = 65 grams.
Computation:
A + (5 + A) + A = 65
3A + 5 = 65
3A = 60
A = 20
A = 20
B = (65 - 40) = 25
C = 20
Projectile is like a cannon shooting a ball so it will be in "free fall"
While in free fall you are subject to gravity pulling the ball down.
Also since it's flying through the air there is air resistance.
So GRAVITY AND AIR RESISTANCE
