Formulate a hypothesis about the stoichiometry of the reaction between NaCl and AgNO3.
MAXImum [283]

Answer:

AgCl + NaNO3 would be the products of the reaction between sodium chloride and silver nitrate.

The stoichiometry of this reaction is written below, and it is because for this reaction to be fulfilled the products have to be in equilibrium with the reactants, since the mass in the reaction is conserved and must be balanced in the amount of molecules that they react to each other.

Explanation:

NaCl + AgNO3 -------------- AgCl + NaNO3

What is the enthalpy of combustion when 1 mol C6H6(g) completely reacts with oxygen? 2C6H6(g) 15O2(g) mc001-1. Jpg 12CO2(g) 6H2O
Andrei [34K]

The enthalpy of combustion of 1 mole of benzene is 3169 kJ/mol .

The first step in answering this question is to obtain the balanced thermochemical equation of the reaction. The thermochemical equation shows the amount of heat lost or gained.

The thermochemical equation for the combustion of benzene is;

2 C6H6(l) + 15 O2(g) → 12 CO2(g) + 6 H2O(g) ΔrH° = -3169 kJ/mol

We can see that 1 mole of benzene releases about 3169 kJ/mol of heat.

For an electron with angular (azimuthal) quantum number ℓ = 2, the magnetic quantum number m can have
Paraphin [41]

Answer:

-2, -1, 0, +1, +2

Explanation:

The quantum numbers describe the quantum state of an electron in an atom. These numbers are symbolized as n, l, m, and s. There are rules for the combination of these numbers. The angular quantum number (ℓ) is related to the magnetic number (<em>m</em>): if ℓ is equal to a number a, thus <em>m</em> can be any integer number between - a and +a.

According to this rule:

If ℓ = 2, thus <em>m</em> can be have a value of an integer between -2 and +2 ⇒ -2, -1, 0, +1, +2
