Why is Francine the most metallic element on the periodic table

Chemistry

Flura [38]3 years ago

The most metallic element is Francium, and you can tell because it's the strongest metal when it comes to reacting with water. This is because its spare electron is further out than that of any other metal.

NOTE: All Francium is radioactive, apart from one form which is an isotope, so it instantly decays if made.

The moles of water that are produced from 373 moles of ammonia present in any chemical reaction is 746 moles.

<h3>What is the stoichiometry?</h3>

Stoichiometry of the reaction gives idea about the amount of entities present in any chemical reaction before and after the reaction.

Given chemical reaction is:

3Al + 3NH₄ClO₄ → Al₂O₃ + AlCl₃ + 3NO + 6H₂O

From the stoichiometry of the reaction it is clear that:

3 moles of Al = produces 6 moles of H₂O

373 moles of Al = produces 6/3×373 = 746 moles of H₂O

Hence required moles of water is 746 moles.

Answer:

The correct answer is - D.  It gets rid of pathogens that invade the body.​

Explanation:

Like all other organ systems, the immune system is an organ system that involves several special organs that helps in fighting any foreign object or infection that invades our body. This organ system produces specific cells or chemicals to fight or kill the microbes, and unnatural change takes place in the body.

The organs involved in the immune system are lymphocytes or white blood cells, the complement system, antibodies, the lymphatic system the thymus, bone marrow, and the spleen.

All these combinedly helps in fighting, killing the microbes or infections that occur in the body, and correct the physiological changes that occur in the body to get rid of pathogens that invade the body.

What is the mass in grams of KBr in 0.400 L of a 0.350 M solution???
melamori03 [73]

Answer:

The answer to your question is: 16.7 g of KBr

Explanation:

Data

mass KBr = ? g

Volume = 0.400 L

Concentration = 0.350 M

Formula

Molarity = moles / volume

moles = molarity x volume

Process

moles = (0.350)(0.400)

          = 0.14

MW KBr = 39 + 80 = 119 g

                                  119 g of KBr --------------------  1 mol

                                   x                 --------------------   0.14 mol

                                   x = (0.14 x 119) / 1

                                   x = 16.7 g of KBr

How many moles of KOH are in 130.0 mL of a 0.85 M solution of KOH? <br> Please help ASAP!!! :(
lana [24]

Answer:

0.1105 moles per 130 ml

Explanation:

For  1 L (1000) of solution, no of moles are =  0.85

For 1 ml of solution, no of moles are = 0.85/1000 moles

For 130 ml of solution, no of moles are=  0.85/1000 x 130

                                                                = 0.1105 moles per 130 ml
