H+O>h2o I believe this is the answer
Answer:
It is prepared small amounts of hydrogen cloride for uses in the lab.
It can be "generated in an HCl generator by dehydrating hydrochloric acid with either sulfuric acid or anhydrous calcium chloride."
Answer: Beryllium phosphide
Explanation:it has a molecular weigt of 88.98407 g/mol
its CID is 16453515
Answer:
Option D. atm, L, K, mole
Explanation:
To know which option is correct, do the following:
We shall use the standard value for each variable to obtain the gas constant. This can be obtained as follow:
Volume (V) = 22400 mL
Pressure (P) = 760 mmHg
Number of mole (n) = 1 mole
Temperature (T) = 273 K
Gas constant (R) =?
PV = nRT
R = PV / nT
R = (760 × 22400) / (1 × 273)
R = 62358.97 mmHg.mL/Kmol
Volume (V) = 22.4 L
Pressure (P) = 760 mmHg
Number of mole (n) = 1 mole
Temperature (T) = 273 K
Gas constant (R) =?
PV = nRT
R = PV / nT
R = (760 × 22.4) / (1 × 273)
R = 62.359 mmHg.L/Kmol
Volume (V) = 22400 mL
Pressure (P) = 1 atm
Number of mole (n) = 1 mole
Temperature (T) = 273 K
Gas constant (R) =?
PV = nRT
R = PV / nT
R = (1 × 22400) / (1 × 273)
R = 82.05 atm.mL/Kmol
Volume (V) = 22.4 L
Pressure (P) = 1 atm
Number of mole (n) = 1 mole
Temperature (T) = 273 K
Gas constant (R) =?
PV = nRT
R = PV / nT
R = (1 × 22.4) / (1 × 273)
R = 0.0821 atm.L/Kmol
From the above illustrations, we can see that the gas constant will have a value for 0.0821 as long as other variables are: atm, L, K, mole
Answer:
Option 3 is correct.
The atomic nucleus of each element has a unique number of protons. Therefore, the energy of the electron layers of the atoms of each element is unique.
If we have the energy released from each electron transfer between the layers of the atom, we can identify the element.
