Answer:
14.33 g
Explanation:
Solve this problem based on the stoichiometry of the reaction.
To do that we need the molecular weight of the masses involved and then calculate the number of moles, find the limiting reagent and finally calculate the mass of AgCl.
2 AgNO₃ + CaCl₂ ⇒ Ca(NO₃)₂ + 2 AgCl
mass, g 6.97 6.39 ?
MW ,g/mol 169.87 110.98 143.32
mol =m/MW 0.10 0.06 0.10
From the table above AgNO₃ is the limiting reagent and we will produce 0.10 mol AgCl which is a mass :
0.10 mol x 143.32 g/mol = 14.33 g
The bond between the N and 0 (double bond) transfers and gives a -ve charge on O and a +ve charge on N atom at the group . Thus the +vely charged nitrogen is electron-deficient pulling electrons towards itself!
The combination of the +vely charged nitrogen and the electronegative oxygen atom leads to delocalization causing the resonance effect.
Atp is a form of energy and it is generated through a chemical process called substrate level phosphorylation.
<h3 /><h3>What is substrate level phosphorylation?</h3>
Substrate-level phosphorylation is a reaction that makes use of substrate to generate Adenosine triphosphate (ATP) which is a form of energy.
ATP is produced through the transfer of phosphate group from the substrate directly to adenosine diphosphate (ADP).
Therefore, substrate-level phosphorylation generates the atp produced in glycolysis.

Answer: 5.26 moles
Explanation:
Given that:
Volume of hydrogen gas V = 8560mL
(since 1000 mL = 1dm3
8560mL = 8560/1000= 8.56dm3)
Standard temperature T = 25°C
Convert temperature in Celsius to Kelvin
(25°C + 273 = 298K)
Pressure P = 1.5atm
Number of moles of hydrogen = ?
Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1
Then, apply ideal gas equation
pV = nRT
1.5 atm x 8.56dm3 = n x (0.0082 atm dm3 K-1 mol-1 x 298K)
12.84atm dm3 = n x 2.44atm dm3 mol-1
n = (12.84atm dm3 / 2.44atm dm3 mol-1)
n = 5.26 moles
Thus, there are 5.26 moles of Hydrogen, H present in this gas sample.
