the glass of water that has been sitting in the sun cause it gathers the heat energy
the more the temperature the more energy
hope you understand and good luck
Chromatography is an analytical method of separating components of the mixture. Particularly, this method uses the paper chromatography. The color indicates the type of substance existing. Each substance is designated to one color only. So, if your paper showed more than one color, it mean that there is more than one component in there. Therefore, Kim's specimen contains more than one component because of the red and blue band.
Explanation:
in this question, we're asked how to determine whether we have a metallic or nonmetallic substance.So what you want to do is one to remember that metals are malleable and Nonmetal are brittle. So if we were to hammer the metal, it would be very malleable, but the nonmetal would fall apart. And never we could just hammer the sample and see whether it was malleable. And therefore it would be a medal or a brittle and therefore being nonmetal.
<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>
HF + NaOH = NaF + H2O
Aqueous sodium fluoride (NaF) and water are the products of the reaction between hydrofluoric acid (HF), a weak acid and sodium hydroxide (NaOH), a strong base.
It is a straightforward acid-base reaction, despite the fact that hydrogen fluoride is a weak acid that doesn't completely dissociate in water (the equilibrium between the dissociated & undissociated acid will however be pushed to the right as the reaction progresses and all of the acid will eventually be neutralized). Water and sodium fluoride are the products
What exactly is an acid-base reaction?
An acid-base reaction is a chemical reaction that occurs between the reactants, which are an acid and a base. This reaction produces salt and water as byproducts. An acid-base reaction is a double replacement reaction in which ions swap positions.
