Answer:
true
Explanation:
heat will destroy the salt components quicker
Answer:
They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.
Explanation:
any of the elements lithium, sodium, potassium, rubidium, cesium, and francium, occupying Group IA
Answer:
Bottle B has a higher temperature than Bottle A.
Explanation:
We have to consider something very important here and that is the ability of the molecules of CO2 and those of air to trap heat.
CO2 molecules are better able to trap heat since it is among the green house gases.
Since CO2 is a greenhouse gas, the temperature of bottle B is higher than that of bottle A because more heat is trapped by the gas in bottle B than the gas in bottle A.
Answer:
Octet Rule is defined as the chemical rule in which atoms tend to form bonds in such a way that it completes its valence shell or tend to achieve the configuration of a noble gas.
Explanation:
The lithium is chemical element, which has atomic number 3. It has one valence electron in its outermost shell, therefore, it will require 7 more electrons to complete its octet.
The element nitrogen has the atomic number 7, such that it has 5 valence electrons in its outer most shell. Therefore, it will require 3 more electrons to complete its octet.
The noble gas Argon have complete octet, such that it does not require any electrons to complete its octet. the gas is inert and non-reactive.
The chemical element Boron has atomic number 5, such that it has three electrons in its outer most shell. Therefore, it will require 5 more electrons to complete its octet.
Hence, the correct option is Nitrogen.
