Answer :position
Explanation:
Potential energy is the energy stored in an object due to its position
<u>Given:</u>
Enthalpy change (ΔH) for SO3 decomposition = +790 kJ
Moles of SO3 = 2.1 moles
<u>To determine:</u>
Energy required when 2.1 moles of SO3 reacts
<u>Explanation:</u>
The decomposition reaction is -
2SO3(g) → 2S(s) + 3O2 (g)
Energy required when 2 moles of SO3 reacts is 790 kJ
Thus, for 2.1 moles of SO3 the energy requirement would be
= 2.1 moles SO3 * 790 kJ/2 moles SO3 = 829.5 kJ
Ans: 830 kJ are required when 2.1 moles of SO3 reacts.
The statements which correctly describe the Cl-Cl bond is:
It is a sigma bond.
It is formed by overlap of two hybrid orbitals.
Explanation:
The 2 atoms of the chlorine atom are bonded by single bond by sharing of electrons as chlorine has 7 electrons in its outer shell.
1s22s2p63s23p5 configuration of each atom
A covalent bond is formed between the two chlorine atoms.
The electrons are shared by molecular orbitals by overlapping the orbital as each of the chlorine atom will try to complete its octet. The electrons from p orbitals are shared hence sigma bond.
There is no hybridization in Cl2 it only has only overlapping of electrons in p orbitals.
<span>The three ways magma can form are when rock is heated, when pressure is released, and when the composition of the rock changes. The temperature of magma is 1300-2400F. Magma collects in magma chambers under the earth's surface, and can be come to the surface in the form of lava.</span>
Answer:
You need to do the following conversion to pass from 3M in 250 mL to g of sodium acetate
Explanation:
First, you need to dissolve 61.52 g of solid sodium acetate (MW 82.03 g/mol) in 200 ml of DI water. Then, using a volumetric flask add water to bring the total volume of the solution to 250 mL.
