Q

What is the word equation for acid and a metal?

A

acid + metal —> salt + hydrogen

16
Q

What is the word equation for acid and an alkali?

A

acid + alkali → a salt + water

17
Q

What is the word equation for acid and a carbonate?

A

acid + carbonate → a salt + water + carbon dioxide

18
Q

How do you test for hydrogen?

A

You have to hold a lit splint in to the gas being tested and if a squeaky pop is heard, hydrogen gas is present.

19
Q

How do you test for carbon dioxide?

A

Bubble the test gas through limewater and it will turn cloudy if carbon dioxide is present.

20
Q

What products are formed when acid reacts with a base?

21
Q

What is the equation when an acid reacts with a base?

A

Acid + base—> Salt + water

22
