The oceanographers define salinity by the number of grams of salt per kilogram of water.
Salinity is illustrated as how much salt is present in the given amount of water. It is dependent upon how much salt is found in the ocean in the specific regions. If there is a sunny environment, it may evaporate an ample amount of water, and leave behind a lot of salt, thus, the water has more salinity.
The salinity of the ocean is usually measured in Practical Salinity Unit (PSU), it is a unit based on the characteristics of seawater conductivity.
Answer:35 electrons
Bromine atoms have 35 electrons and the shell structure is 2.8. 18.7. The ground state electron configuration of ground state gaseous neutral bromine is [Ar
Explanation:
Answer : The pressure of the hydrogen gas exert before its volume was decreased will be, 2.28 atm
Explanation :
According to the Boyle's law, the pressure of the gas is inversely proportional to the volume of the gas at constant temperature of the gas and the number of moles of gas.
or,
or,
where,
= initial pressure of the gas = ?
= final pressure of the gas = 5.09 atm
= initial volume of the gas = 12.16 L
= final volume of the gas = 5.45 L
Now put all the given values in this formula, we get the initial pressure of the gas.
Therefore, the pressure of the hydrogen gas exert before its volume was decreased will be, 2.28 atm
No! That’s why they’re called theories. Most of them have a lot of facts to back it up however the theories themselves are either proven or just hypothetical.
Answer:
Explanation:
6.90 mol x grams
2As + 6NaOH = 2Na3AsO3 + 3H2
6 mol 2 mol
192 g/mol
6.90 mol NaOH x 2 mol Na3AsO3/6 mol NaOH== 2.3 mol Na3AsO3
2.3 mol Na3AsO3 x 192 g/mol = 442 g Na3AsO3
