44Given the equation representing a reaction at equilibrium :2SO2(g) + O2(g) ==> 2SO3(g) + heat

1 answer:

4 0

(2) Adding more O2(g) would shift the equilibrium to the right because a higher concentration of oxygen is offered than its initial position, therefore more products have to be yielded to maintain equilibrium.

Lena [83]

Answer:

The correct answer is 17 meq/g

Explanation:

Ion exchange capacity (IEC) express the total of active sites of a resin in which ions are attached because the greater molecular weight.

The exchange Reaction can be represented as

R-H $R-H^{+} + Na^{+} + Cl^{-} -> R-Na^{+} + HCl_{aq}$

The IEC value (in meq/g) is determinated by using the next equation:

IEC=[(mL of NaOH)*(M of NaOH)]/mass of resin

IEC [(17 mL)*(0.5 M)/0.5]= 17 meq/g

Which atom absorbs more energy, one in which an electron moves from the second shell to the third shell or an otherwise identica

Assoli18 [71]

Answer:

identical atom in which an electron moves from the first to the third shell.

Atoms may occupy different energy states. The energy states are discrete, i.e. they occur at specific values only. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels.

The lowest possible energy level that the atom can occupy is called the ground state. This is the energy state that would be considered normal for the atom.

An excited state is an energy level of an atom, ion, or molecule in which an electron is at a higher energy level than its ground state.

An electron is normally in its ground state, the lowest energy state available. After absorbing energy, it may jump from the ground state to a higher energy level, called an excited state.

why is a graduated cylinder most appropriate for measuring the volume of a liquid instead of a beaker ?

katovenus [111]

Answer:

Graduated cylinders are designed for accurate measurements of liquids with a much smaller error than beakers. They are thinner than a beaker, have many more graduation marks, and are designed to be within 0.5-1% error. ... Therefore, this more precise relative of the beaker is just as critical to almost every laboratory.

What is the gram formula mass of Ca3(PO4)2

Georgia [21]

Mass Molar of $Ca_{3} (PO_4)_2$
Ca = 3*40 = 120 amu
P = 2*31= 62 amu
O = (16*4)*2 = 64*2 = 128 amu
--------------------------------------
Mass Molar of $Ca_{3} (PO_4)_2$ = 120 + 62 + 128 = 310 g/mol

Therefore: <span>What is the gram formula mass of Ca3(PO4)2 ?
