What mass of hcl gas must be added to 1.00 l of a buffer solution that contains [aceticacid]=2.0m and [acetate]=1.0m in order to
Paraphin [41]
PH of acidic buffer = pKa + log [CH₃COONa - HCl] / [CH₃COOH + HCl]
pKa of CH₃COOH = 4.74
Concentration of acetic acid in buffer = 2.0 M
Concentration of sodium acetate = 1.0 M
Concentration of HCl must add = x
pH = 4.74 + log (1-x) / (2+x) = 4.11
x = concentration of HCl must be added = 0.43 M
number of moles of HCl = M * V = 0.43 * 1 = 0.43 mol
mass of HCl must be added = 0.43 * 36.5 = 15.7 g

How many joules are required to heat 2 l of water in a pot from 20 ◦c to the boiling point of water? the specific heat of water
miss Akunina [59]
  The  joules  required  to   heat 2L  of  water  in  a  pot  from  20  c  to  the  boiling  point  of  water  is  calculated     using the following  formula

  Q=    MC  delta  T
M  = mass  =   density  x   volume(  2  x 1000= 2000ml)
M  =     1g/ml  x2000  ml  =  2000g
C  =  specific  heat   capacity =  4.18  g/c
delta  T  =  change  in  temperature  =  100 c (  boiling  point  of  water)   -  20 c =  80 c 
Q  is therefore  =   2000 g x 4.18 j/g c  x  80c  =  668800j

Write the ions present in a solution of K2CO3. Express your answers as chemical formulas separated by a comma. Offset subscripts
meriva

Answer:

K ^+ , CO3 ^2-

Explanation:

The compound is potassium trioxocarbonate(IV).

It contains cation (potassium ion) and acid radical ( trioxocarbonate (IV) ion).

Since K is in group 1 of the periodic table, it loses one electron to form ion i.e K^1. trioxocarbonate IV ion has a charge of 2-.and so the ions of the compound are as shown in the answer above.
