Answer:
jobs growth is a figure measured by the Bureau of Labor Statistics (BLS) that tracks how many jobs are created in the country on a monthly basis. The figure is used as a measure of economic expansion and regarded as a litmus test for national economic health
Explanation:
Answer:
Force = Pressure × Area
Explanation:
Easy, just invert the equation. Transpose the force variable over to the left of the equals sign, and transpose the pressure variable back to the right side.
I'm pretty sure it's D. Compounds
Salt water is an example of a solution, and a solution is a type of mixture, so by multiple choice logic none can be the right answer! Seriously though - mixture are combinations of two compounds that are physically combined but do not undergo a chemical reaction with one another to produce a new compound. For instance, when you dissolve salt in water, you don't produce any new products, and you can boil away the water to leave only the salt (a physical method of separation). You cannot separate a compound by physical means because by definition this would be a chemical reaction as you're breaking bonds.
Answer: a substance that increases the hydroxide ion concentration of a solution
Explanation: According to Arrhenius concept, an acid is a substance which donates hydronium ions ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
ions when dissolved in water and base is a substance which donates hydroxide ions ![[OH^-]](https://tex.z-dn.net/?f=%5BOH%5E-%5D)
ions in water.
According to the Bronsted Lowry conjugate acid-base pair, an acid is a substance that donates protons and a base is a substance that accepts protons.
According to Lewis concept, an acid is the substance which accepts electron pairs and abase is a substance which donates electron pairs.
Thus a substance that increases the hydroxide ion concentration of a solution is an Arrhenius base.
The two substances have different densities. Density can be affected by the temperature of a substance. Since they have to same volume but weigh differently, they have different densities. Remember, density = mass/volume
