The atomic size / radius generally increases, as when we move down the group, it means that there is an additional shell compared to the last element. For example, K has one more electron shell than Na does, so the atomic size generally increases as we move down a group in the periodic table.
I believe your answer would be NaOH.
Hope this helps.
Carbon dioxide is the main gas
1 mole -------- 22,4 L ( at STP )
0.030 moles --- ?
V = 0.030 * 22,4 / 1
V = 0.672 L
hope this helps!
For electricity to flow there must be a flow of electrons or ions present in a system or medium. When electricity is passed in pure water, oxygen does not have d-orbitals or f-orbitals through which electrons may pass. In pure water there are no electrolytic substance, so no ions present in the pure water. Therefore electricity can not pass through pure water. Additionally; water cannot dissociate into OH- and H+ when electricity is passed through pure water.
