Answer:
This is because of the release of hydrogen gas in the reaction.
Explanation:
Metals react with water and produce a metal oxide and hydrogen gas. It also starts floating due to the bubbles of hydrogen gas sticking to its surface.
For eg:
<u>2Mg. + 2H2O --------> 2MgOH + H2</u>
Here,
Metal taken is <u>magnesium(2Mg)</u> which when reacts with <u>water(2H2O)</u> to form its <u>oxide form (2MgOH)</u> and <u>hydrogen gas(H2)</u> is released which comes outside water as bubbles.
Answer:
repeat the experiment
Explanation:
I am big brain. if she wants to know if it is correct, repeating the exact ay would show her if it is right or if she did something wrong
The temperature is -8 F
Answer D
They form molecules which can be in solution form if diluted in water, but some do form solutions on exposure to the atmosphere i.e they are deliquescent like pellets of sodium hydroxide
