Answer:
Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart.
Explanation:
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
Atoms bound together and form molecules. Molecules are a little more complex than atoms. For example water is composed of two hydrogen atoms and one oxygen atom which are both gases. Properties of oxygen and hydrogen are completely different than water molecules.
Answer:
a. He is missing a control group of mice that did not receive the new antibiotic.
Explanation:
In any experiment especially experiments testing effectiveness of a drug, there should be a control group.
The importance of a control group is to minimize the effects of other variables other than the independent variable hence increasing reliability of the results.
in this case, a group of mice that did not receive the new antibiotic would have served as the control group.
