Answer:
3.99998575239 pounds per gallon (US)
Answer: Thus concentration of
in
is 0.011 and in
is 0.814
Explanation:
To calculate the concentration of
, we use the equation given by neutralization reaction:
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
are the n-factor, molarity and volume of acid which is ![HCl](https://tex.z-dn.net/?f=HCl)
are the n-factor, molarity and volume of base which is ![Ca(OH)_2](https://tex.z-dn.net/?f=Ca%28OH%29_2)
We are given:
![1cm^3=0.001dm^3](https://tex.z-dn.net/?f=1cm%5E3%3D0.001dm%5E3)
Putting values in above equation, we get:
![1\times 0.06mol/dm^3\times 0.011dm^3=2\times M_2\times 0.030dm^3\\\\M_2=0.011mol/dm^3](https://tex.z-dn.net/?f=1%5Ctimes%200.06mol%2Fdm%5E3%5Ctimes%200.011dm%5E3%3D2%5Ctimes%20M_2%5Ctimes%200.030dm%5E3%5C%5C%5C%5CM_2%3D0.011mol%2Fdm%5E3)
The concentration in
is ![0.011mol/dm^3\times 74g/mol=0.814g/dm^3](https://tex.z-dn.net/?f=0.011mol%2Fdm%5E3%5Ctimes%2074g%2Fmol%3D0.814g%2Fdm%5E3)
Thus concentration of
is
and ![0.814g/dm^3](https://tex.z-dn.net/?f=0.814g%2Fdm%5E3)
Answer:
See explanations
Explanation:
a. Molarity = moles/Volume in Liters = 5moles/2Liters = 2.5M in NaCl
b. Freezing Pt Depression
1. Sprinkling salt on icy surfaces
2. Using antifreeze in automobile cooling systems
3. <em>Not an application
</em>
4. Using salt to make ice cream
c. pOH = -log[OHˉ] = -log(1x10ˉ¹⁰) = -(-10) = 10 => pH = 14 – pOH = 14 – 10 = 4
d. H₂O + NH₃ => NH₄⁺ + OHˉ => Bronsted Acid is H₂O (proton donor)
Answer:
The formal thinker would take a systematic approach in the combination of the liquids, thereby eliminating several unnecessary combinations that the concrete thinker would definitely combine.
Explanation:
The formal operational stage in thinking begins when a child gets to the age of 12 and continues to adulthood. The formal operational stage provides an individual with the ability to think abstractly by manipulating ideas in their head without concretely manipulating it. A concrete would have to see something to be able to manipulate any ideas.
No
Magnesium Chloride is MgCl2
The method I use to name ionic compounds is 'swap and drop'
Mg oxidation number is +2 and Cl oxidation number is -1
Mg^2+ Cl^-1
'swap'
Mg^1 Cl^2
'drop'
MgCl2
