Answer:
<h3>The answer is 0.81 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 10.5 g
volume = 13 cm³
We have
We have the final answer as
<h3>0.81 g/cm³</h3>
Hope this helps you
Answer:
Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products.
Explanation:
Answer:
The equilbrium constant is 179.6
Explanation:
To solve this question we can use the equation:
ΔG = -RTlnK
<em>Where ΔG is Gibbs free energy = 12.86kJ/mol</em>
<em>R is gas constant = 8.314x10⁻³kJ/molK</em>
<em>T is absolute temperature = 298K</em>
<em>And K is equilibrium constant.</em>
Replacing:
12.86kJ/mol = -8.314x10⁻³kJ/molK*298K lnK
5.19 = lnK
e^5.19 = K
179.6 = K
<h3>The equilbrium constant is 179.6</h3>
They have similar electron configurations and have similar ionic chargers
