The M stands for molar, so it would be 5.0 molar. is that what you need?
Answer:
3. x 10⁸m/s
Explanation:
Given parameters:
Frequency of wave = 7.8 x 10⁶Hz
Unknown:
Speed of the wave = ?
Solution:
All electromagnetic radiation has a speed of 3. x 10⁸m/s in free space.
No matter the frequency and wavelength, they all have the same speed which is the same as the speed of light.
<span>Assume you have 1.00 L (1000 mL) of solution.
d = m / V
m = d x V = 1.23 g/mL x 1000 mL = 1230 g of solution
0.387 mol/L x 1 L = 0.387 mol HCl
0.387 mol HCl x (36.5 g / 1 mol) = 14.1 g HCl
mass of water = 1230 g solution - 14.1 g HCl = 1216 g H2O = 1.216 kg H2O
molality = mol HCl / kg water = 0.387 mol / 1.216 kg = 0.318 mol/kg (or 0.318 molal)</span>
Answer is: false.
<span>According to the principle of base pairing hydrogen bonds could form between adenine and thymine (two hydrogen bonds between this nucleobases) and guanine and cytosine (three hydrogen bonds between this nucleobases).
Adenine and guanine are </span>purine derivatives and thymine and cytosine are pyrimidine<span> derivates.</span>
Explanation:
Relation between 
and 
is as follows.
![K_{p} = K_{c} [RT]^{\Delta n}](https://tex.z-dn.net/?f=K_%7Bp%7D%20%3D%20K_%7Bc%7D%20%5BRT%5D%5E%7B%5CDelta%20n%7D)
Given, temperature = 
= (830 + 273) K = 1103 K
R = 8.314 J/mol K
= 1 - 0 = 1
Now, putting the given values into the above formula as follows.
0.5 = 
ICE table for the given reaction will be as follows.
Initial: c - -
Equilibrium: (c - x) x x
= ![[CO_{2}]](https://tex.z-dn.net/?f=%5BCO_%7B2%7D%5D)
= x
Hence, same amount of CaO is produced.
Moles of CaO =
Mass of CaO = 
= 0.310 g
Thus, we can conclude that 0.310 g of CaO produced when equilibrium is established.
