Answer:
620.71 L the final volume of the balloon.
Explanation:
Initial volume of the gas in the balloon= 
Initial pressure of the gas in the balloon= 
Initial temperature of the gas in the balloon= 
Moles of gases = n
...[1]
Final volume of the gas in the balloon = 
Final pressure of the gas in the balloon = 
Final temperature of the gas in the balloon = 
Moles of gases = n
...[2]
[1] = [2]
620.71 L the final volume of the balloon.
Its B and D
...............................................................
Explanation:
When we move across a period from left to right then there will occur an increase in electronegativity and also there will occur an increase in non-metallic character of the elements.
As sulfur (S) is a group 16 element and chlorine (Cl) is a group 17 element. Hence, sulfur (S) is more metallic in nature than chlorine.
This means that chlorine (S) is less metallic than chlorine (Cl).
Both indium (I) and aluminium (Al) are group 13 elements. And, when we move down a group then there occur an increase in non-metallic character of the elements. As indium belongs to group 13 and period 5 whereas aluminium belongs to group 13 and period 3.
Therefore, aluminium (Al) is more metallic than indium (In).
Arsenic (Ar) is a group 15 element and bromine (Br) is a group 17 element. Therefore, arsenic is more metallic than bromine.
Answer:
Explanation:
Hello!
In this case, since the formula for the calculation of molarity is:
Whereas we can compute the moles of the solute as shown below, making sure the volume is in liters:
Thus, by plugging in we obtain:
Next, since the molar mass of NaCl is 58.44 g/mol, we obtain the following mass:
