Answer:

n NaHCO3 = 9.6 E-3 mol

Explanation:

balanced reaction:

2 NaHCO3(s) + H2SO4(ac) ↔ Na2SO4(ac) + 2 CO2(g) + 2 H2O(l)

assuming a concentration of H2SO4 6M....normally worked in the lab

⇒ n H2SO4 = 8 E-4 L * 6 mol/L = 4.8 E-3 mol H2SO4

according to balanced reaction, we have that for every mol of H2SO4 there are two mol of NaHCO3 ( sodium bicarbonate)

⇒ mol NaHCO3 = 4.8 E-3 mol H2SO4 * ( 2 mol NaHCO3 / mol H2SO4 )

⇒ ,mol NaHCO3 = 9.6 E-3 mol

So 9.6 E-3 mol NaHCO3, are the minimun moles necessary to neutralize the acid.

Can we use electrical equipment near water? Explain Why?

tiny-mole [99]

Answer:

You may, but it is too risky.

Even though you are being cautious around using electric equipment around water, you'll never know what can happen. You might accidentally drop that piece of electrical equipment you are using into the water. Water can be splashed around by someone or something without you noticing it and it may affect the object you are using. Sometimes, if water comes in contact with an electrical object, it may cause you electric shocks or the equipment you are using has a chance of exploding and may hurt you. You can guarantee that waterproof electrical equipment is safe to use, but it is better not to risk it too much.

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

<h3>What are organs?</h3>

Organs are a collection of tissues that are closely related and which perform a related function.

The role and function of the organs of the digestive system are as follows:

Pancreas - produces pancreatic juice which contain digestive enzymes
Liver - produces bile for the emulsification of fat
Stomach - serves as a temporary store of food and produces digestive juices
Small intestine - functions in food digestion
Large Intestine - helps to remove undigested food from the body

Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.
