Concentration of H+ ions in HNO3 solution is 10⁻¹ which is equal to 0.1 M
putting the value we get
So, the required option is A) 1
The change of energy : 4.8744 x 10⁺¹⁹ J
<h3>Further explanation</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸
λ = wavelength
The wavelength is 4078 A = 4.078 x 10⁺⁷ m
Answer:
I think emi should put it in a metal container and put it in the direction of the sun cause this will help produce heat as the sun shines on the metal container
Answer:
a. Ethanol.
b. 4.21 mL H2O.
c. 87.8%
Explanation:
Hello,
- For the limiting reactant, the available amount of ethanol is less than the ideal amount of ethanol that would react with the given amount of oxygen, that's why it is the limiting one.
- You will find the calculations in the attached picture; take into account that the molecular mass of water is 18 g/mol and ethanol 46 g/mol.
- The percent yield is allowed to be computed in terms of volume as well, because the relationships are conserved.
Best regards!
Explanation:
kclo3- 39+35.5+16*3=122.5
molar mass = 122.5
mass = 14.0g
volume= 100cm3
solubility in mol/dm3 or molarity = ?
but we know that
no of moles = solubility in mol/dm3×vol in cm3
---------------------------------------------
1000
no of moles = mass
---------
molar mass
mass\molar mass= solubility in mol/dm3 *vol in cm3/ 1000
14.0/122.5=x * 100/1000
solubility =0.875 mol/dm3
