Answer: The final concentration of a solution is 0.350 M
Explanation:
According to the dilution law,
where,
= concentration of concentrated acid solution = 12.0 M
= volume of concentrated acid solution = 35.0 ml
= concentration of diluted acid solution= ?
= volume of another acid solution= 1.20 L = 1200 ml
( 1L=1000ml)
Putting in the values:
The final concentration of a solution prepared by diluting 35.0 mL of 12.0 M HCl to a final volume of 1.20 L is 0.350 M
Carbon 14 and carbon 12 are the same element because they contain the number of proton in the periodic table. but the different in number (14 and 12) is from the neutron
From my understanding its considered a compond
Answer:
47,9 kJ/g
Explanation:
The enthalpy of combustion is the change in energy due the reaction of combustion of n-octane. If the enthalpy is -4,79x10⁷ J/kg And knowing (1000J = 1kJ) (1000g = 1kg). The enthalpy of combustion expressed in kJ/g is:
= <em>47,9kJ/g</em>
