Answer:
D-when the aim is to show electron distributions in shells
Explanation:
We will use ideal gas equation in this problem
PV = nRT
Where
P = pressure of gas or air = ?
V = volume of air = volume of pressure cooker = 5.68 L
T = temperature = 394 K
n = moles of air = 0.355
R = ideal gas equation = 0.0821 L atm / mol K
Putting values
Pressure = nRT / V = 0.355 X 0.0821 X 394 / 5.68 = 2.02 atm.
The first one you did wrong on the side its GG not GgThe second one is wrong to on the side it its Tt not TTthe third one is wrong to on the side its tt, not TTthe last one is wrong to is wrong to the top is RR and the side is rr P.S i did this 1 year ago :PPPPthat the one i did to and the other one too *sigh*

<h2>Yes it is balanced as number of atoms of each element has to be same on reactant and product side</h2>
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
![Mg+2HCl\rightarrow MgCl_2+H_2](https://tex.z-dn.net/?f=Mg%2B2HCl%5Crightarrow%20MgCl_2%2BH_2)
Thus in the reactants, there are 2 atoms of hydrogen , 2 atoms of chlorine and 1 atom of magnesium.
Thus there will be 2 atoms of hydrogen , 2 atoms of chlorine and 1 atom of magnesium in the product as well.
Thus the above equation is balanced
