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.

Consider 2 Al + 6 HCl → 2 AlCl3 + 3 H2 , the reaction of Al with HCl to produce hydrogen gas. What is the pressure of H2 if the
Margaret [11]

Answer : The pressure of hydrogen gas is 8.96 atm.

Explanation :

The given balanced chemical reaction is:

2Al+6HCl\rightarrow 2AlCl_3+3H_2

From the balanced chemical reaction we conclude that,

As, 2 moles of Al react to give 3 moles of H_2 gas

So, 4.50 moles of Al react to give \frac{3}{2}\times 4.50=6.75 moles of H_2 gas

Now we have to calculate the moles of H_2 gas when percent yield is 75.4.

\text{The moles of }H_2=75.4\% \times 6.75=\frac{75.4}{100}\times 6.75=5.09moles

Now we have to calculate the pressure of H_2 gas.

Using ideal gas equation :

PV = nRT

where,

P = Pressure of hydrogen gas = ?

V = Volume of the hydrogen gas = 14.0 L

n = number of moles of hydrogen gas = 5.09 moles

R = Gas constant = 0.0821L.atm/mol.K

T = Temperature of hydrogen gas = 300 K

Putting values in above equation, we get:

P\times 14.0L=5.09mol\times 0.0821L.atm/mol.K\times 300K\\\\P=8.96atm

Therefore, the pressure of hydrogen gas is 8.96 atm.
