Answer:
Using glucose to provide energy for the body
Explanation:
Answer:
The side with lots of H+ and low pH
Explanation:
Because one of the feature of an acid is the ability to dissociate to H+.
And it has lower pH because the concentration of H+ is more than OH-
After the first 30 minutes,
dT = 75-60
= 15
dt = 30 mins
k = (15/60) * (60 - 38)
k = 5.5
After 60 minutes,
dT = 60 - T
dt = 30
(60 - T)/30 = 5.5(T - 38)
60 - T = 165T - 6270
166T = 6330
T = 38.13°F
We are asked to calculate the number of moles in a given mass of a substance. To be able to calculate it, we need the molar mass of the substance. For (NH4)2Cr2O7, the molar mass would be <span>252.07 g/mol. We calculate as follows:
0.025 g </span>(NH4)2Cr2O7 ( 1 mol / 252.07 g ) = 0.0001 mol <span>(NH4)2Cr2O7
Hope this answers the question. Have a nice day.</span>
<span>Answer:
mole of Cl- in 0.140 L of 0.25 M NH4Cl = 0.140 * 0.25
mole of Cl- in 0.380 L of 0.75 M CaCl2 = 0.380 * 0.75
Total = 0.140 * 0.25 + 0.380 * 0.75 = 0.32</span>
