The standard atomic weight is the average mass of an element in atomic mass units ("amu"). Though individual atoms always have an integer number of atomic mass units, the atomic mass on the periodic table is stated as a decimal number because it is an average of the various isotopes of an element.
Yes you can it will not just have 5 :)
Answer: The number of grams of
in 1620 mL is 1.44 g
Explanation:
According to ideal gas equation:

P = pressure of gas = 1 atm (at STP)
V = Volume of gas = 1620 ml = 1.62 L (1L=1000ml)
n = number of moles = ?
R = gas constant =
T =temperature =


Mass of hydrogen =
The number of grams of
in 1620 mL is 1.44 g
Answer:
Products have a lower total Gibbs free energy in comparison with the reagents total Gibbs free energy.
Explanation:
Hello,
Exergonic chemical reactions are those that the overall Gibbs free energy is negative, it means that the products have a lower total Gibbs free energy, turning out into a spontaneous chemical reaction. Such reactions are thermodynamically possible under standard conditions and they usually release heat.
Best regards.
