0.1 M x 0.5L = 0.05 mols HCl.
Adding 25 mL 2M NaOH is
2M x 0.025 L = 0.05 mols NaOH.
What you want to do is to back off very slightly with the NaOH (you might try something like 24.95 mL which I calculate to give 0.00019 M or a pH of 3.7. Inching closer, 24.99 mL would leave H^+ of 4E-5 for pH 4.4. The problem here is two-fold.
hope it helps
Answer:
Hello my friend! The correct answer is "The process shown in the image can best be described as a rapid chemical reaction where gas is released"
Explanation:
Most antacid products uses Sodium bicarbonate (NaHCO3). When placed in water, NaHCO3 reacts with acids very rapidly, releasing CO2, according to the chemical reaction below:
NaHCO3 + HCl → NaCl + H2O + CO2
Answer:
The composition of air this is because it vmade up of oxygen, nitrogen, Nobel gages and Carbon dioxide
<span>Li ----> Li+ + e-(oxidation)
now comes </span>
<span>Reduction: </span>
<span>H2 + 2e- ------> 2H
now by
</span>Multiplying (1) by 2 and adding in (2) will give you the required equation..
..
<span>2Li + H2 ---------> 2LiH
</span>half reaction are either oxidation or reduction
Answer:
Boiling point.
Explanation:
Flammability, reactivity and toxicity are all chemical properties!
