I think that the answer might be B.
Answer:
The new volume of the gas is 276.45 mL.
Explanation:
Charles's law indicates that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases, and as the temperature decreases, the volume of the gas decreases.
Charles's law is a law that mathematically says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
Analyzing an initial state 1 and a final state 2, it is satisfied:
In this case:
- V1= 250 mL
- T1= 293 K
- V2= ?
- T2= 324 K
Replacing:
Solving:
V2= 276.45 mL
<em><u>The new volume of the gas is 276.45 mL.</u></em>
Answer:
The correct answer is A and D.
Explanation:
Please I want brainliest.
Reason:
The size of the ions follows the order:
Negatively charged ion > Neutral atom >
Positively charged ion
This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.
This happens due to the increase in
electron-electron repulsion.
Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.
Thus the size of the positively charged ion is least.
To solve this questions you first need to find the number of moles of barium phosphate you have. The molar mass of barium phosphate is 601.93g/mol.
24.4/601.83 = 0.0402 moles barium phosphate
Then you need to use avagadro’s number, 6.022 x 10^23, which is the number of molecules or formula units in a mole.
6.022 x 10^23 * 0.0402 = 2.42 x 10^22 formula units
