Answer:
11.61 is the pH of 10.0 mL of a solution containing 3.96 g of sodium stearate.
Explanation:
Concentration of sodium stearate acid : c
Moles of sodium stearate = 
Volume of the solution = 10.0 mL = 0.010 L

![[C_{17}H_{35}COO^-]=c=1.294 M](https://tex.z-dn.net/?f=%5BC_%7B17%7DH_%7B35%7DCOO%5E-%5D%3Dc%3D1.294%20M)

initially c
c 0 0
At equilibrium
(c-x) x x
Dissociation constant of an acid = 
Expression of a dissociation constant of an acid is given by:

Solving for x;
x = 0.0041 M
![[OH^-]=0.0041 M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D0.0041%20M)
The pOH of the solution:
![pOH=-\log[OH^-]=-\log[0.0041 M]=2.39](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5BOH%5E-%5D%3D-%5Clog%5B0.0041%20M%5D%3D2.39)
pH = 14 -pOH
pH = 14 - 2.39 = 11.61
11.61 is the pH of 10.0 mL of a solution containing 3.96 g of sodium stearate.
Answer:
1 and 2 are most likely to happen to the cell if cell membrane doesn't function properly
Explanation:
It is because if cell membrane doesn't function properly then cell will not be able to exchange materials in its surrounding.
Answer:
C. Filtration will cease
Explanation:
Generally, blood hydrostatic pressure (BHP) in the capillaries of human body drives filtration. A significant change in the value of the blood hydrostatic pressure leads to a corresponding change in the rate of filtration. The higher the change in the BHP, the higher the change in filtration and vicer versa. Thus, if BHP changes to 45 mmHg, filtration will cease.
Answer : 58.44 g
<h3>Further explanation</h3>
The reaction

mole ratio :
Na : Cl : NaCl = 1 : 1 : 1
Molar mass of Na : 22,989769 g/mol = 22.99 g/mol
Molar mass of Cl : 35,453 g/mol= 35.45 g/mol
Molar mass of NaCl : 58,44 g/mol
Let's check the mol for reactant (Na and Cl) and product(NaCl)


Then the reactants are completed reacting because it matches the mole ratio, which is 1: 1
so that the mole of the product can be determined from the mol Na or Cl, which is 1

Difference between molecular weight and molar mass
Hint : Molar mass of molecules is also called molecular weight . Its unit is gram per mole. We can calculate molar mass of molecule with the help of following rules; ... Molar mass of nitric acid (HNO3) =atomic mass of hydrogen + atomic mass of nitrogen +3× atomic mass of oxygen .
