<span>Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.</span>
That is false, volume is the amount of space that a substance or object occupies
The sentence is FALSE. The space inside the solid is the volume of the system.
Answer : The volume of gas needed are, 90 L
Explanation : Given,
Volume of = 60 L
Now we have to determine the volume of needed.
As we know that at STP, 1 mole of gas contains 22.4 L volume of gas.
The given balanced chemical reaction is:
By the stoichiometry we can say that, 2 moles of react with 3 moles of oxygen gas to give 2 moles of gas and 2 moles of water vapor.
From the balanced reaction we conclude that,
As, volume of react with volume of gas
So, volume of react with volume of gas
Thus, the volume of gas needed are, 90 L
Answer:
Explanation:
Let's consider the following reaction.
CO(g) + 2 H₂(g) ⇌ CH₃OH(g)
The equilibrium constant (Kc) is <em>the products of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentration of the reactants raised to their stoichiometric coefficients.</em>
If you wanted to calculate [CH₃OH], suppose that the molar concentrations for CO and H₂ at equilibrium are [CO] = 0.04 M and [H₂] = 0.08 M. The concentration of methanol at equilibrium is:
