Compounds that has two elements on the formula can be bonded by ionic or covalent bond. If the compound is a metal and a non-metal then it will be ionic bonding. However, when it involves two non-metals, then it will have covalent bonding.
Answer:
Other side
Opposite function
On both sides of the equation
In the numerator and not the denominator
Explanation:
To isolate a single variable when rearranging equations, move all other variables to the other side of the equation by using the opposite function on them and remembering to perform that operation on both sides of the equation. Make sure the rearrangement has the target variable in the numerator, not the denominator.
TABLE SALT IS A SUBSTANCE.
In chemistry, a substance refers to a matter which has specific composition and specific properties which do not change. A substance can be an element or a compound. A substance typically has a constant composition, which can not be separated by physical methods.
In the question given above, table salt is an example of a chemical substance because, it has a constant specific composition and its components can not be separated by physical methods.
Seawater and sand are not substances, because they have varied compositions and their components can be separated by physical methods.
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.
