what happens when you combine group 2 with water

Back (Answer)

Mg + 2H2O —> Mg(OH)2 +H2

#2
Front (Question)

reaction of Mg with steam and what is observed

Back (Answer)

Mg + H2O —-> MgO + H2 bright white fame , whit powder formed

#3
Front (Question)

what happens to hydroxide solubitly down group 2

Back (Answer)

increases down the group

#4
Front (Question)

what happens to sulfate solubitly down group 2

Back (Answer)

it decreases

#5
Front (Question)

Mg in metal extraction of titanium chloride

Back (Answer)

TiCl4 + 2Mg —> 2MgCl2 + Ti

#6
Front (Question)

redox reactions of halogens with H2SO4

Back (Answer)

F- / Cl- = NaF + H2SO4 ——> NaHSO4 + HF Br- = NaBr + H2SO4 ——> NaHSO4 + HBr 2HBr + H2SO4 ——> Br2 + SO2 + 2H2O I- = NaI + H2SO4 ——> NaHSO4 + HI = 2HI + H2SO4 ——> I2 + SO2 + 2H2O = 6HI + SO2 ——> H2S + 3I2 + 2H2O

#7
Front (Question)

reaction of chlorine with water

Back (Answer)

Cl2 + H2O ——> ClO- + Cl- + 2H+

#8
Front (Question)

equation of chlorine decomposing water in the presence of UV light

Back (Answer)

2Cl2 + 2H2O ——> 4HCl + O2

#9
Front (Question)

production of bleach reactants and equation

Back (Answer)

chlorine mixed with cold aqueous sodium hydroxide 2NaOH +Cl2 ——> NaClO + NaCl + H2O

#10
Front (Question)

test for sulfates and results

Back (Answer)

BaCl2 ( barium chloride) => white ppt

#11
Front (Question)

test for hydroxides and results

Back (Answer)

red litmus => turns blue universal indicator => blue/ purple

#12
Front (Question)

test for carbonates and results

Back (Answer)

add acid (HCl) => effervesce and CO2 gas given off (bubble through lime water)

#13
Front (Question)

test for group 2 and results

Back (Answer)

flame test calcium = red strontium = brick red barium = pale green

#14
Front (Question)

test for ammonium (NH4+) and results and way to speed up test

Back (Answer)

red litmus paper over a petri dish => blue (add NaOH to produce ammonia gas faster)

Front (Question)

what is the property of aluminum that allows it to act as both an acid and base

Back (Answer)

amphoteric

#21
