Answer:
2 because if you look on the periodic table the number of the element tells you how many atoms is in it
Explanation:
<u>Ans: P = 22.5% and Cl = 77.5%</u>
<u></u>
<u>Given:</u>
Total Mass of sample containing P and Cl = 50.51 g
Mass of P produced = 11.39 g
<u>To determine:</u>
Mass % of P and Cl
<u>Explanation:</u>
Mass % of a given element in a total mass is generally expressed as:
Mass % of element = [mass of element/total mass]*100
Here,
Total mass = mass of P + mass of Cl
mass of Cl = Total - mass of P = 50.51-11.39 = 39.12 g
% P = [11.39/50.51]*100 = 22.5%
%Cl = [39.12/50.51]*100 = 77.5%
A: The reaction force accelerates the bat in a direction opposite that of the ball.
Answer:
Glucose
Explanation:
Glucose molecule is the primary source of energy for most organisms where processes such as glycolysis starts and cellular respiration follows. Bodies of organisms can get energy from carbohydrates, proteins and fats with carbohydrates being the main component for energy where they are converted to glucose which is a form of sugar that reacts to affect blood sugar levels within an hour or two hours after eating.
The second answer option, table salt (NaCl) is incorrect because sodium added in food is vital for functioning of nerves and muscles. Additionally, it helps in fluid regulation and control of blood pressure/volume in the body.
The third answer , hydrochloric acid is not correct because presence of hydrochloric acid in the body helps in breaking down, digestion and absorption of nutrients.
The correct answer choices are : A and D.
