The reaction H2SO4 + 2 NaOH -> Na2SO4 + 2H2O applies to an acid-base tritration.
moles NaOH = c · V = 0.2343 mmol/mL · 29.45 mL = 6.900135 mmol
moles H2SO4 = 6.900135 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 3.4500675 mmol
Hence
[H2SO4]= n/V = 3.4500675 mmol / 38.54 mL = 0.08952 M
The answer to this question is [H2SO4] = 0.08952 M
Answer:
2 K(s) + Cl₂ (g) --> 2 KCl(s)
Explanation:
Potassium will just be K
Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂
Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl
Balancing the amounts of each will lead to 2 K(s) + Cl₂ (g) --> 2 KCl(s)
8%
Explanation:
In a DNA molecule the no. of Adenine bases equal to that of Thymine bases
The no. of Cytosine bases equal to that of Guamine bases.
If we take no. of Thymine bases as x and no. of Cytosine bases as y,
Adenine + Thymine + Cytosine + Guamine = 100
x + x + y+y = 100
2( x+y) = 100
x+y = 50
y=42
therefore x= 50-42 = 8%
Answer: It wasn't that long ago that frames were made out of cast iron or even wood. Today bicycles are made out of exotic materials such as titanium, aluminum, and carbon fiber. Bicycle frames in the 1990s are lighter and stronger than ever before. A racing bicycle frame with parts of the frameset indicated.
