The answer is Strontium(Sr). The reactive increase from right to left. And this element has two valence electrons. So Rb is not correct. Then the very reactive metal is Sr.
The density of ice is less than the density of water.
Fun fact: Water is the only known liquid that has this change it density.
Answer:
C2H5OH is a formula of ethyl alchol or ethanol.
alkenes are characterisized by carbon-carbon double bond.
burning is an example of exothermic reaction
atomic number of element is x the symbol of its ion is +1 bcz it will lose one electron
if temperature increases then rate of chemical reaction increases
Explanation:
i hope this will help you :)
