Answer:

I think the best answer is migration. In an alpine biome, animals have two problems which is the very cold temperature and the UV rays from the sun. Most alpine animals hibernate and migrate to warmer areas of the mountains when the temperature continues to drop.

Which of the substances below would dissociate into ions when dissolved in water? Select all that apply.

dusya [7]

Answer:

B. NaBr

D. KOH

Explanation:

Below is the solubility rules given for you knowledge.

Salts of

Group 1 elements are soluble( $Li^+, Na^+, K^+,Cs^+, Rb^+$ )
Ammonium ion is soluble ( $NH4^+$ )
The nitrate are generally soluble( $NO3^-)$

of Cl- , Br- , and I- are soluble, except Ag+ , Pb+2, and (Hg2)+2
most sulfate are soluble, except Ba+2, Ca+2,Pb+2, Ag+, Sr+2.
most hydroxide salts are only slightly soluble, except NH+4, Li+, Na+, K+
Most carbonates are insoluble (CO3 2-) Except group 1 and NH+4
most phosphate are insoluble except group 1 and NH+4

so using the rules above

NaBr , KOH are soluble, Pb(OH)2 is slightly soluble and AgCl is not soluble.

(3) 1. HCl NaOH: In Part I: An aqueous solution of sodium hydroxide reacts with an aqueous solution of hydrochloric acid, yieldi

FinnZ [79.3K]

Answer:HCl(aq) + NaOH (aq) -> NaCl (aq) + H2O(l)

Explanation:

The reaction of HCl and NaOH is a neutralization reaction. When an acid and a base react salt and water is produced.

HCl(aq) + NaOH (aq) ----> NaCl (aq) + H2O(l)

Because the reactants and products are ionic compounds, they exist as ions in a solution.

H+(aq) + Cl-(aq) + Na+(aq) + OH-(aq) -------> Na+(aq) + Cl-(aq) + H2O(l)

The aim of a neutralization reaction is the formation of water. Na+(aq) + Cl-(aq) remain the same on both the reactants side and the products side, the net ionic reaction will be

H+(aq) + OH-(aq) -------> H2O(l)

I'll explain with the help of examples:

Solution :is basically two substances that are evenly mixed together. One of them is called the solute and the other is the solvent
Solvent: is the substance to be dissolved (sugar).
