Answer:
2NaOH + 2Al +2H2O = 2NaAlO2 +3H
Explanation:
Aluminum is an amphoteric element it reacts with both bases and acids to form a salt and hydrogen gas.The reaction is highly exothermic.
The units of light energy emitted by blackbody radiation is originally called as quanta. Black body radiation is a type of radiation within a boy in thermodynamic equilibrium. This is a theoretical body. In 1900, Planck proposed that light and other electromagnetic waves were emitted in discrete packets of energy which were called "quanta". This was the original unit used.
C. Carbon tetra–bromide is a non–polar compound, for the four Bromines balance out the dipole moment from the tetrahedral bonds they form on Carbon.
In a controlled experiment the factor tested is called the experimental group
<u>Answer: </u>The chemical formula for Palladium(IV) sulfate is 
<u>Explanation:</u>
Palladium is the 46th element of the periodic table which has an oxidation state of +4 (because it is a metal and will form positive ion) and sulfate is the polyatomic ion having a charge of -2 with formula 
So, to write the formula of the compound, we do criss cross method in which oxidation state of each element or ion is given to the other combining atom which results into the formation of a neutral compound.
The chemical formula of the compound is
The image is given below.
