The reaction between NaOH and H₂SO₄ is as follows;
2NaOH + H₂SO₄ ---> Na₂SO₄ + 2H₂O
stoichiometry of base to acid is 2:1
NaOH is a strong acid and H₂SO₄ is a strong acid, therefore complete ionization into their respective ions takes place.
number of acid moles reacted - 0.112 M / 1000 mL/L x 39.1 mL = 0.0044 mol
the number of base moles required for neutralisation = 0.0044 x 2 = 0.0088 mol
Number of NaOH moles in 25.0 mL - 0.0088 mol
Therefore in 1000 mL - 0.0088 mol/ 25.0 mL x 1000 mL/L = 0.352 mol/L
Therefore molarity of NaOH - 0.352 M
An animal could be the toucan, overtime it grew a longer beak in order to access food that other birds couldn’t get. this increases the chances of successful reproduction because being able to survive longer than other birds to the beak and providing food for the babies, they can reproduce multiple times
<span>When 2,3-bisphosphoglycerate (2,3-BPG) levels increase, hemoglobin release oxygen.
</span>2,3-bisphosphoglycerate is present in human red blood cells (erythrocyte).
2,3-BPG <span>nteracts with deoxygenated hemoglobin and decrease his affinity for oxygen, so it </span>allosterically<span> promotes the release of the remaining oxygen molecules.</span>
Answer:
temperature
amount
Explanation:
Under the postulate of Boyle's law, both temperature and amount(number of moles) are kept constant.
According to Boyle's law "the volume of a fixed mass of gas varies inversely as the pressure changes if the temperature is constant"
Based on the premise of this law, both temperature and amount of substance is kept constant.
