Answer:

3(NH4)2S + 2AlCl3 → 6NH4Cl + Al2S3

Explanation:

Firstly, ammonium sulfide has a chemical formula of (NH4)2S while aluminum chloride has a chemical formula of AlCl3. These two chemical substances react as follows:

(NH4)2S + AlCl3 → NH4Cl + Al2S3

This chemical equation is however, unbalanced. To balance the chemical equation, one has to ensure that the atoms of each element on both the reactant and product side equates with one another.

If we carefully observe each atom on both the reactants and product side, we will have the following balanced equation:

3(NH4)2S + 2AlCl3 → 6NH4Cl + Al2S3

That is;

- 6 moles of N and Cl on both sides

- 24 moles of H on both sides

- 3 moles of S on both sides

- 2 moles of Al on both sides

Metals lose electrons under certain conditions to attain a noble gas electron configuration. How many electrons must be lost by

viva [34]

Answer:

2 electrons

E. neon

Explanation:

Metals lose electrons under certain conditions to attain a noble gas electron configuration. Magnesium has 12 electrons and its electron configuration is

1s² 2s² 2p6⁶ 3s²

When magnesium loses 2 electrons, it acquires the electron configuration of neon (10 electrons).

The reaction N O space plus thin space O subscript 3 space rightwards arrow space N O subscript 2 space plus thin space O subscr

nikklg [1K]

Answer:

4.3 × 10⁻⁵ M s⁻¹

Explanation:

Step 1: Given data

Rate constant (k): 2.20 × 10⁷ M⁻¹s⁻¹

Concentration of NO ([NO]): 3.3 × 10⁻⁶ M

Concentration of O₃ ([O₃]): 5.9 × 10⁻⁷ M

First order with respect to both NO and O₃

Step 2: Write the balanced reaction

NO + O₃ ⇒ NO₂ + O₂

Step 3: Calculate the reaction rate

The rate law is:

rate = k × [NO] × [O₃]

rate = 2.20 × 10⁷ M⁻¹s⁻¹ × 3.3 × 10⁻⁶ M × 5.9 × 10⁻⁷ M

rate = 4.3 × 10⁻⁵ M s⁻¹

How much energy is required to melt a 20.0lb bag of ice a 0°c? A pound (lb.) is equivalent to 0.4536. The Hfusion of ice is +6.0

erma4kov [3.2K]

To compute the energy, Q, needed to melt a certain amount of ice, n, in moles, we have

$Q = n \Delta H_{f}$

where the latent heat of fusion for ice is equal to 6.009 kJ/mol.

Now, since we have a 20.0 lb ice, we must first convert its mass to grams. Thus mass = (20.0)(1000)(0.4536) = 9072 g.

To find the number of moles present, we must recall that the molar mass of water (ice) is equal to <span>1.00794(2) + </span><span>15.9994 </span>≈ 18.01 g/mol. Hence, we have

$ice_{moles} = (\frac{9072 g}{1})(\frac{1 mol}{18.01 g}) =503.72 moles$

Now, to compute for the molar heat of fusion, Q,

$Q = (503.72)(6.009) = 3026.9 kJ$

Therefore, the amount of heat needed to melt the 20-lb bag of ice is equal to 3026.9 kJ.

Answer: 3026.9 kJ
