Answer:
pH = 4
Solution is acidic
Explanation:
Given data;
Hydronium ion concentration = 1 × 10⁻⁴ M
pH of solution = ?
Solution:
pH = -log [H₃O⁺]
pH = -log [ 1 × 10⁻⁴ ]
pH = 4
According to pH scale the pH 7 is neutral while the pH less than 7 is acidic and greater than 7 is basic. The given solution has pH 4 it means solution is acidic.
Use the question marck Moles of CO2
The the giving = 0.624 mol O2
Find the CF faction = 1 mole= 32.00 of O2
O= 2x16.00= 32.00amu ( writte this in the cf fraction)
SET UP THE CHART
Always start with the giving
0.624 mol O2 / 1mol of CO2
___________ / _____________ = Cancel the queal ( O2)
/ 32.00c O2
/
/
Multiply the top and divide by the bottom
0.624 mol CO x 1mol CO2 = 0.624 divide by 32.00 O2 =0.0195
You should look at the giving number ( how many num u gor ever there)
Ur answer should have the same # as ur givin so
= 0.0195
= .0195 mol of CO2
Answer:
cerium (iii) sulfate is less soluble
Where are the following elements to choose from?
Answer:
The correct answer is it adds a UMP molecule to glucose-1-phosphate by splitting out pyrophosphate.
Explanation:
UDP glucose pyrophosphorylase enzyme also known as UTP-glucose-1-phsphate uridylyltransferase.
This enzyme plays an important role during synthesis of glycogen also known as glycogenesis.
During the reaction the enzyme UDP glucose pyrophosphorylase transfer uridine monophosphate to glucose-1-phosphate resulting in the formation of UDP glucose along with the release of pyrophosphate moiety.
Glucose-1-phosphate+UTP⇆UDP-glucose+ppi
