Describe the interactions of the nervous and muscular system. please write a paragraph and do not plagiarize If you need to cite

Ksenya-84 [330]

The systems within the body associate with each other to keep the organism in a healthy state. Though every system of the body exhibits particular functions, they all are dependent and inter-associated with each other. The nervous system controls various systems of the body.

The muscular system comprises distinct kinds of muscles that permit motion, produce heat to sustain a temperature of the body, does contraction of the heart, and move the food via the digestive tract. It comprises three kinds of muscles, that is, smooth, skeletal, and cardiac muscles.

The muscular system coordinates with the nervous system and does various functions. The receptors found in muscles instruct the brain with the information regarding the movement and position of the body. The brain monitors the contraction of skeletal muscle. The nervous system monitors the speed at which food passes through the digestive tract.

How many moles of aluminum are needed to make 9 moles of molecular hydrogen? given the reaction: 2 al + 6 hcl → 2 alcl3 + 3h2 6

sergiy2304 [10]

1) Chemical equation

2Al + 6 HCl ---> 2Al Cl3 + 3 H2

2) molar ratios

2 mol Al : 3 moles H2

3) Proportion

2 mol Al / 3mol H2 = x / 9 mol H2

4) Solve for x

x = 9 mol H2 * 2 mol Al / 3 mol H2 = 6 mol Ag

Answer: 6 moles
