Total weight of alloy is
67 + 20 = 87 g
67 g of which is gold
So % gold is 67/87* 100 = 77.01%
Answer: The pressure of the gas in atmospheres is 1.76
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 70.0 L
n = number of moles = 
R = gas constant =
T =temperature =
Thus the pressure of the gas in atmospheres is 1.76
This statement lons form because the loss of one or more electrons makes them less stable than their corresponding atoms; this state requires more energy to maintain is FALSE.
- An ion forms when an atom loses or gains one more electrons.
- This loss or gain of electrons causes the ion to gain the stable octet configuration.
- This stable octet configuration requires less energy to maintain than the corresponding atom.
So, since the stable octet configuration of the ion requires less energy than the corresponding atom, the statement is false.
So, the statement lons form because the loss of one or more electrons makes them less stable than their corresponding atoms; this state requires more energy to maintain is FALSE.
