Compare and contrast acids and bases in terms of their h+ ion and oh- ion concentrations.

1 answer:

3 0

Acids mainly have H+ ions in their formulas. When ionized in water, acids yield H+ ions into the water.

Bases mainly have OH- ions in their formulas. When ionized in water, bases yield OH- ions into the water.

Based on this, we can conclude that acids have higher concentrations of H+ while bases have higher concentrations of OH-.

If a solution has equal concentrations of H+ and OH-, then this solution is said to be neutral.

How do tectonic plates move at convergent subduction boundaries? Insert a drawing with the arrows that show the movement

boyakko [2]

Answer:

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

write balanced equations for each of the following by insert- ing the correct coefficients in the blanks: (a) cu(no3)2(aq) koh(a

viktelen [127]

The balanced reaction equations are given below. They are all examples of double displacement.

a) balanced reaction equation of the reaction between aqueous copper(II) nitrate and aqueous potassium hydroxide, resulting in the formation of solid copper(II) hydroxide and aqueous potassium nitrate

$Cu(NO_{3} )_{2}(aq)+2KOH(aq)$ → $Cu(OH)_{2} (s) + 2KNO_{3}(aq)$

b) balanced reaction equation of the double displacement between gaseous boron cyanide and liquid water resulting in the formation of solid boric acid and gaseous hydrogen cyanide

$2B(CN)_{3} (g) + 6H_{2} O$ → $2H_{3} BO_{3} (s)+6HCN(g)$

c) balanced reaction equation between solid calcium silicate and gaseous hydrogen fluoride resulting in the formation of gaseous silicon fluoride, solid calcium fluoride and liquid water

$CaSiO_{3}(s) + 6HF (g)$ → $SiF_{4}(g)+CaF_{2}(s)+3H_{2}O(l)$

d) balanced reaction equation between cyanogen gas and liquid water resulting in formation of aqueous oxalic acid and gaseous ammonia

$(CN)_{2}(g) + 4H_{2} O (l)$ → $H_{2} C_{2} O_{4} (aq) +2NH_{3} (g)$
