Electric current can be generated by moving a metal wire through a magnetic field. It is also different than static electricity, which is the accumulation of charges on a surface. <u>Electric generators rotate a coil</u> of wires through a magnetic field.
Answer:
<em><u>Metal oxides</u></em>
Explanation:
Al2O3, ZnO and SnO are typical amphoteric oxides. Metal oxides are usually basic and they react with acids to form their respective salts
Answer:
5.25 grams of potassium sulfate will get crystallize out.
Explanation:
Solubility of potassium sulfate at 40 °C = 15 g/100 g
This means that at 40 °C 15 g of potassium sulfate will get completely dissolved in 100 of water.
39.0 g of potassium sulfate to 225 g water, carefully heating the solution.
Amount of potassium sulphate will get dissolve in 225 g of water at 40 °C will be:
× 225 = 33.75g
Amount of potassium sulfate precipitated out by the solution:
= 39.0 g-33.75 g = 5.25 g
At 40 °C 5.25 g of potassium sulfate will get precipitate out from the solution which means that solution is saturated.
Saturated solution are solution in which solute is dissolved in maximum amount. Further addition of solute results in precipitation of solute form the solution.
5.25 grams of potassium sulfate will get crystallize out.
(Hope this Helps can I pls have brainlist (crown)☺️)
If it’s (5.93 x 10^3) x (2.3 x 10^-2)
The answe is:
= 13.63 x 10^1
Round to the nearest two significant figures.
= 14 x 10^1
Making sure it’s in proper scientific notation.
[= 1.4 x 10^2]
Answer:
False
Explanation:
Watershed is the area of land where all of the water that drains off of it goes into the same place—a river, stream or lake.
