Answer:
The answer to your question is V2 = 1244 L
Explanation:
Data
Temperature 1 = 11°C
Volume = 1.03 x 10³ L
Temperature 2 = 70°C
Volume 2 = ?
To solve this problem use the Charles' law
V1/ T1 = V2 / T2
-Solve for V2
V2 = V1T2 / T1
Process
1.- Convert temperature to °K
Temperature 1 = 11°C + 273 = 284°K
Temperature 2 = 70°C + 273 = 343°K
2.- Substitution
V2 = (1.03 x 10³)(343) / 284
3.- Simplification
V2 = 353290 / 284
4.- Result
V2 = 1244 L
The answer is (D) microscopic. You can remember this, because the name is very close to "microscope," an instrument used to greatly magnify and observe tiny organisms and objects.
You would use the density difference to separate the sand, evaporate the water out (the water vapor will cool back to water if collected). Then use a magnet to get the iron fillings out of the salt.
Answer:
1. First one is true : as per periodic table down the group , the elements has increasing order of shell & with that the London dispersion forces brings the inter-molecules close together and bromine converted into liquid .
2. second one is False because carbon-carbon bonds are not weak bonds they form mutual covalent bonds which are stronger bonds and cannot be easily disrupted .
3. A single carbon atom has the valency of 4 so it can be bonded with four hydrogen atom at the same time .
Explanation:
Answer:
a. 59 m/atm
Explanation:
- To solve this problem, we must mention Henry's law.
- <em>Henry's law states that at a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.</em>
- It can be expressed as: C = KP,
C is the concentration of the solution (C = 1.3 M).
P is the partial pressure of the gas above the solution (P = 0.022 atm).
K is the Henry's law constant (K = ??? M/atm),
∵ C = KP.
∴ K = C/P = (1.3 M)/(0.022 atm) = 59.0 M/atm.
