Answer:
Free Energy (G) can either increase or decrease for a reaction when the temperature increases. It depends on the entropy (S) change. The change in a quantity is represented by the Greek letter delta. ... Hence, when the temperature increases the numeric value of the free energy becomes larger.
Explanation:
Answer : The line-angle formula for 
is shown below.
Explanation :
Condensed structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.
Line-angle formula : In the line-angle formula, the carbon atoms are represented at the corner and ends of the lines with some angle and the hydrogen atoms are hidden.
The line-angle formula for is shown below.
Answer:
Answer A is wrong
Explanation:
because the temperature increases as soon as the temperature increases

Answer:
frequency = velocity of light /wavelength
wavelength = velocity / frequency
=3 x10^8 / 5.9 x 10^11
=0.508 x 10^-3.
The molar mass of calcium carbonate is 100 mg/mmol, so the
number of moles is:
moles CaCO3 = 500 mg / (100 mg/mmol) = 5 mmol
We see that there is 1 mole of Ca per 1 mole of CaCO3,
therefore:
<span>mass Ca = 5 mmol * (40.08 mg/mmol) = 200.22 mg</span>
