Its a displacement reaction
Answer:
The correct answer is a. The volume of the gas increases.
Explanation:
In this case, we apply Boyle Mariotte's Law: for a given gas mass at constant temperature, the pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa).
If the pressure reduced, the volume increases according to the formula: P1xV1 = P2xV2
Answer:
Glucose is the building block for starch
Explanation:
(amylose and amylopectin)
For this question, we can use relations for pH and pOH. We calculate as follows:
pOH = -log [OH-]
pOH = -log [<span>1.83x10^-7 M]
pOH = 6.74
pH + pOH = 14
pH = 14 - 6.74
pH = 7.26
pH = -log [H3O+]
7.26 = -log[H3O+]
[H3O+] = 5.46 x 10^-8 M
Hope this answers the question. Have a nice day.</span>
