When KCl dissolves in water Question 22 options: 1) the Cl- ions are attracted to dissolved K ions. 2) the Cl- ions are attracted to the partially negative oxygen atoms of the water molecule. 3) the K ions are attracted to Cl- ions on the KCl crystal. 4) the K ions are attracted to the partially negative oxygen atoms of the water molecule. 5) the K ions are attracted to the partially positive hydrogen atoms of the water molecule.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

answer: h+ its less than oh

explanation:

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

i'm assuming that the correct answer is indeed the first one/ "a"..
