anyone answer?
sodium gives off an orange to yellow flame colour
NaO sodium oxide
Sodium (Na) does not really dissolve in water. It reacts with it to form Sodium Hydroxide (NaOH) and Hydrogen (H2) gas which bubbles off.
The gas is methane (CH4).
The calcium metal will react with the water to form calcium oxide and give off Hydrogen gas.
Chlorine can be obtained from sodium chloride by electrolysis.
Be sure that it is not possible.
what kind of gas do apples give off
sodium gives off an orange to yellow flame colour
NaO sodium oxide
No. Neither High or Low pressure Sodium Vapour lamps give off much energy in the UV wavelengths.
green kryptonite gas
Of course not.
They give off carbon dioxide.
That is a chemical change. You are seeing a chemical reaction, where the sodium reacts with the water, forming sodium hydroxide and hydrogen gas.
Ethylene
Baking soda is sodium bicarbonate and when it comes in contact with acids like HCl, it will form sodium salts (NaCl in this case) and give off carbon dioxide gas with H2O. In case of contact with H2SO4, it will form sodium sulphate, carbon dioxide and water.
