Answer: Option (c) is the correct answer.
Explanation:
A hydrogen bond is defined as a weak bond that is formed between an electropositive atom (generally hydrogen atom) and an electronegative atom like oxygen, nitrogen and fluorine.
An ionic bond is defined as a bond formed between a metal and a non-metal and in this bond transfer of electron takes place from metal to non-metal. And, due to the presence of opposite charges on the combining atoms there exists a strong force of attraction.
Vander waal forces are defined as the weak electric forces which tend to attract neutral molecules towards each other in gases, liquefied and solidified gases.
Vander waal forces are very weak forces.
Thus, we can conclude that Van der walas interactions are weak interactions would require the least amount of energy to disrupt.
I believe it is pentane..Try that!
Hope it helps, sorry if it doesn't but that's the answer I just choose for my unit test on edgnty.
Answer:
B
Explanation:
A chemical bond is formed when there is a transfer or sharing of electrons. When there is a transfer, what we have is that the electrons completely leave the outermost shell of an atom, usually metal to the outermost shell of another atom, usually a nonmetal. This particularly alters the electronic configuration of these atoms. This is ionic or electrovalent bonding
Now, electron sharing is also another way of chemical bond formation. Electrons might be shared between two atoms in a case principally known as covalent bonding. The electrons here are controlled by the 2 nuclei

Answer:</h3>
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
<h3>
Explanation:</h3>
We are required to complete the chemical equation given;
strontium carbonate + sulfuric acid → ??
- We know that, carbonates reacts with acids to form a salt, water and carbon dioxide.
- Strontium carbonate reacts with sulfuric acid to form strontium sulfate, water and carbon dioxide.
- Therefore, the equation for the reaction is;
SrCO₃ + H₂SO₄ → SrSO₄ + H₂O + CO₂
- The equation is balanced as the number of atoms of each element are equal on both sides of the equation.
