Answer:
Explanation:
In this case, we have to remember that relationship between the <u>avogadro's number</u> and the "mol" concept:
With this in mind, we can do the <u>first conversion</u>:
Now, if we calculate the molar mass of 
. <u>The atomic mass of O is 16 g/mol and the atomic mass of H is 1 g/mol</u>, so:
(16*1)+(1*2)= 18 g/mol
In other words, 
, so:
I hope it helps!
Answer:
1.2029 J/g.°C
Explanation:
Given data:
Specific heat capacity of titanium = 0.523 J/g.°C
Specific heat capacity of 2.3 gram of titanium = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
1 g of titanium have 0.523 J/g.°C specific heat capacity
2.3 × 0.523 J/g.°C
1.2029 J/g.°C
Solution :
"Aldol" stands for the abbreviation, aldehyde and alcohol. When a ketone or an aldehyde's enolate reacts with the carbonyl of a molecule at the alpha carbon, under the acidic or basic conditions so as to obtained the ketone or β-hydroxy aldehyde, is known as an aldol reaction.
For the conversion of the aldol addition product of a 3-hydroxy-3-(4-nitrophenyl)-1-(2-pyridyl)-1-propanone to an aldol condensation product of (E)-3-(4-nitrophenyl)-1-(2-pyridyl)-1-propenone, the mechanism is given in the diagram a below :
The answer is C. Distillation. Distillation is a common process for separating liquid mixtures by using the principle of volatility and boiling point. For a liquid mixture with two liquid components A and B, A will have a lower boiling point or higher volatility than B. By boiling the mixture at the boiling point of component A, only component A will evaporate from the mixture. The evaporated gas will then be cooled to condense component A back to a liquid.
Answer:
True
Explanation:
It is true as metals form a positive ion when they take part in a chemical reaction. Nonmetals form an anion when bonding.
