Higher than.
that’s because ionic bonds are stronger and more complex than covalent bonds, so more heat is required to break them <3
We Know, Atomic number of Gold (Au) = 79
1) Number of Protons = Atomic number = 79
Number of Electrons = Number of Protons = 79
Number of Neutrons = mass number - Atomic number = 195-79 = 116
2) Atomic number = 79 [ written on top of the element ]
Mass number = 195 [ written on bottom of the element ]
Hope this helps!
The other ion would be Oxygen or O1.
Answer:
0.89 times
Explanation:
Let the initial volume of the tank be V.
Finally, we shall determine how much larger the final volume of the gas will be. This is illustrated below:
Initial pressure (P₁) = 130 kPa
Initial volume (V₁) = V
Final pressure (P₂) = 145.5 kPa
Final volume (V₂) =?
P₁V₁ = P₂V₂
130 × V = 145.5 × V₂
130V = 145.5 × V₂
Divide both side by 145.5
V₂ = 130V / 145.5
V₂ = 0.89V
Therefore, the final volume of gas will be 0.89 times the initial volume.
The chromosomes when a cell is about to divide are formed by DNA wrapping its self around histone proteins and so the chromosomes condense and become thicker and visible this is important as it makes sure that the DNA is all organised and eases the cells division
hope that helps
