Answer:
Explanation:
Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon
dioxide as shown below.
CaCO3(s) = CaO(s) + CO2(g)
The Kp for this reaction is 1.16 at 800°C. A 5.00 L vessel containing 10.0 g of CaCO3(s)
was evacuated to remove the air, sealed, and then heated to 800°C. Ignoring the volume
occupied by the solid, what will overall mass percent of carbon in the solid once equilibrium is reached?
Explanation:
The number of moles of solute present in liter of solution is defined as molarity.
Mathematically, Molarity =
Also, when number of moles are equal in a solution then the formula will be as follows.
It is given that is 8.00 M, is 7.00 mL, and is 0.80 M.
Hence, calculate the value of using above formula as follows.
= 70 ml
Thus, we can conclude that the volume after dilution is 70 ml.
Answer:
A microbiome is the community of micro-organisms living together in a particular habitat.
Explanation:
Answer:
0.15 l of 4.0 m stock KCl solution should betaken
Explanation:
N1V1=N2V2
6*0.1=V2*4
V2=0.15L
Answer : The mass of nitric acid is, 214.234 grams.
Solution : Given,
Moles of nitric acid = 3.4 moles
Molar mass of nitric acid = 63.01 g/mole
Formula used :
Now put all the given values in this formula, we get the mass of nitric acid.
Therefore, the mass of nitric acid is, 214.234 grams.
