Faahfaahinta casharka

Natiijada casharka

I can use experimental evidence to organise several metals in order of their reactivity.

Muuji qoraalka

Some metals react with acid to produce a metal salt and hydrogen gas. Some metals react with water to produce a metal hydroxide and hydrogen gas. Some metals react with oxygen to form a metal oxide. The reactivity series for metals shows how vigorously metals react, compared to each other. The higher the position of a metal in the reactivity series, the more vigorously it is likely to react.

Imtixaannada

1. Waa kee mid ka mid ah sifooyinkan kuwa ugu badan ee lala xiriirinayo biraha (metals)?
- Jawaabta saxda ah:inay yihiin kuleyliye wanaagsan (thermal conductor)
- inay yihiin kuwo jajaban (brittle)
- inay yihiin kuwo aan si fiican u qaadin korantada (poor electrical conductor)
- inay yihiin kuwo la qaabayn karo (malleable)
2. Go'aami in hadalkan soo socdaa uu yahay run ama been iyo sababta ay taasi sax u tahay: 'Curiyeyaasha midabka cagaarka ah lagu muujiyey sawirkan dhamaantood waa bir (metal).'
- run
- Jawaabta saxda ah:been
- hydrogen waa bir aan ahayn (non-metal)
- dhamaantood waa kuwa aan bir ahayn (non-metals)
3. Arday ayaa qoray jumladan: 'Marka bir ay falceliso, waxay samaysaa cusbo iyo gaas.' Dooro hadalka si sax ah u sharxaya arrintan.
- Jawaabta saxda ah:Marka bir ay la falceliso asiidh (acid), waxay samaysaa cusbo bir ah iyo hydrogen.
- Marka bir ay falceliso, waxay samaysaa xumbo iyo cusbo.
- Marka bir ay la falceliso asiidh, waxay samaysaa non-metal.
- Marka bir ay la falceliso asiidh, waxay samaysaa gaas hydrogen.

1. Maxaa dhacaya marka daasad (tin) lagu daro biyo, sababtuna waa maxay?
- Jawaabta saxda ah:wax falcelin ah ma dhacaan
- falcelin ayaa dhacda
- sababtoo ah daasaddu waxay leedahay falcelin ku filan oo ay ula falceliso biyaha
- sababtoo ah daasaddu uma falcelin karto biyaha sababtoo ah ma laha falcelin ku filan
2. Falcelinta magnesium iyo hydrochloric acid waa mid aan dib loo celin karin. Haddii acid iyo waqti ku filan la siiyo, falcelintu waxay gaadhaa dhamaadka. MgCl$$_2$$ waa mid aad u milmi kara. Maxaad arki doontaa marka falcelintu joogsato?
- weel gabi ahaanba madhan
- Jawaabta saxda ah:weel leh wax u eg biyo
- weel leh dareere, oo cusbo ku ururtay xagga hoose
- weel leh gabal magnesium oo ka yar oo ku jira wax u eg biyo
