Answer: ammonium bromide : acidic : The pH will be less than 7.

potassium cyanide : basic :The pH will be more than 7.

calcium nitrate: neutral : The pH will be approximately equal to 7.

calcium hypochlorite : basic :The pH will be more than 7.

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.

When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.

ammonium bromide : NH_4Br : acidic as it is formed from the combination of strong acid HBr and weak base NH_4OH

potassium cyanide :KCN:  basic, as it is formed from the combination of weak acid HCN and strong base KOH

calcium nitrate: Ca(NO_3)_2 : neutral, as it is formed from the combination of strong acid and strong base.

calcium hypochlorite :  Ca(ClO)_2 : basic, as it is formed from the combination of weak acid HOCl and strong base Ca(OH)_2

In 36 hours the amount of radioactive substance has reduced from 80 mg to 10 mg. What is the half-life of this isotope?
rusak2 [61]
Half-life refers to the time taken for half of the atoms in a radioactive substance to decay. Therefore in 1 half-life the 80 mg of substance will reduce to 40 mg. In another half-life it will reduce from 40 mg to 20 mg, then in a third half-life from 20 mg to 10 mg. Therefore the half-life is equal to the total time taken to decay from 80 mg to 10 mg divided by 3:
t(1/2) = 36 hours / 3 = 12 hours.

What type of bond will form<br><br> Nitrogen and Tellurium
sineoko [7]

Answer: Vander waals

Explanation:

Tellurium is a chemical element with atomic number 52. It's symbol is Te.

Nitrogen is a chemical element with atomic number 14. Its symbol is N

VANDER WAALS bond is found between Nitrogen and Tellurium, just as in Tellurium(II) Nitrogen.

This bond is relatively weak compared to some other kinds of bonds.

That is why tellurium and most of its compounds are usually brittle and easily grounded.

So, Vander Waals bonds is the answer
