Answer:

Engineering is all about solving problems using math, science, and technical knowledge. And engineers have solved a lot of problems in the world by designing and building various technologies. We have everything from machines that can breathe for you in hospitals to suspension bridges to computers we use every day. All of these things were once designed by engineers using the engineering design process.

Determine the mass of KNO3 that dissolves in 100 grams of water at 40°C to produce a saturated solution
velikii [3]
From a solubility curve the solubility of KNO3 at 40°C is about 63 g / 100 g of water.


That means that 100 g of water at 40°C can dissolve 63 g of KNO3.


A saturated solution is one that cannot dissolve more solute, because it already has reached the greatest concentration that it can hold.


Then, the mass of KNO3 that dissolves in 100 g of water is about 63 g.

1. Ionization energy is the energy needed to remove an electron from an atom. We can use the periodic table to predict ionizatio
just olya [345]

Ionization energy increases from left to right because the left wants to lose elctrons and the right wants to gain electron

As you go a group it is easier lose lose because the electrons are farther away from the nucleus and there is less attraction from the positive charges.

It should be 3p3. the p level can hold 6 electrons

Rubidium group 1, 1 valence electrons very reactive

Mg2,2 very reactive

Al 3, 3 reactive
