Answer:
Here just look at the pic here
Explanation:
Answer:
two atoms both non metals
Explanation:
because if the bond is formed between atoms with similar electronegativity since covalent bonding is the sharing of electrons
You can explain what it means...like how gas tends to expand when heated and just tie it up with the sentence you want to make....(i dont know if that was helpful?)
Answer:
5. A strong base increases the OH- ion concentration in an aqueous solution.
6. It has more hydrogen ions.
Explanation:
5. Arrhenius theory states that acids donate H+ ions to a solution and bases donate OH- ions to a solution.
6. pH < 7 so the solution is acidic. Acidic solutions have more hydrogen or hydronium ions. Hydrogen and hydronium ions are essentially interchangeable.
Answer:
B
Explanation:
Neutralization reaction is where you add equal moles or quantity of acid and base so that they both neutralize each other or "cancel" each other making the pH to be neutral which is 7. Group B is likely wrong as their pH is 5 which means they added too much acid, if they had equal acid and base their pH would be 7 however since they added more acid, there was still some acid left after the initial neutralization and this acid decreased the pH to 5.
