Sort of hard but it is 56.8

56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

What is mass?

A body's mass is an inherent quality. Prior to the discovery of a atom or particle physics, it was widely considered to be tied to the amount of matter inside a physical body. It was discovered that, despite having the very same quantity of matter in theory, different atoms and elementary particles have varied masses.

There are various conceptions of mass in contemporary physics that are theoretically different but physically equivalent. The resistance of the body to acceleration in the presence of a net force can be measured experimentally as mass. The gravitational pull an object has on other bodies is also influenced by its mass.

2 Al + 3 Cl[tex]_2[/tex] → 2 Al C l[tex]_3[/tex]

mole of Al =  135.0/ 26=5.19mol

mole of Cl[tex]_2[/tex] = 75.0/ 35 =2.14 mol

mass of aluminum chloride =  56.8g

Limiting reagent = Al

excess reactant =  Cl[tex]_2[/tex]

Therefore, 56.8g of aluminum chloride will be produced if the reaction begins with 135.0 g Al and 75.0 g chlorine gas.

The mass of a single gold atom is 3.27X10^-22 grams. How many gold Adams with there be in 57.8 mg of gold.

Answers

Answer:

18 * 10^19 atoms

Explanation:

We must first convert 57.8 mg to grams.

If 1000 mg = 1g

  57.8 mg = 57.8/1000 = 57.8 * 10^-3 g

Now;

If 1 gold atom has a mass of 3.27X10^-22 grams

x gold atoms have a mass of 57.8 * 10^-3 g

x = 57.8 * 10^-3 g/3.27X10^-22 g

x = 18 * 10^19 atoms

Please no Bs answers. Only going to be reported.

If water is added to 145 mL of a 0.55 M KOH solution until the volume is 250 mL, what will the molarity of the diluted solution be?

What is the molarity of the solution that results from diluting 35.0 ml of a 9.02M solution to a new volume of 45.0 ml?​

Answers

We can use the equation for dilutions that relates concentration and volume:

[tex]M_1V_1=M_2V_2[/tex]

where M is the molarity, V is the volume, and 1 and 2 refer to the initial and final states of the solution, respectively. Here, we are given the molarity of the initial solution and the volumes of the initial and final (diluted) solutions. To find the final concentration (i.e., the molarity of the diluted solution), we would be solving for M₂:

[tex]M_2=\frac{M_1V_1}{V_2} = \frac{(0.55 \text{ M})(145 \text{ mL})}{250 \text{ mL}} \\ M_2 = 0.319 \approx 0.32 \text{ M}.[/tex]

The molarity is given to two significant figures as both our M₁ and V₂ are given to two significant figures.

Note: Although our volumes are in mL instead of L, we do not need to convert them to L for the purposes of our calculation since we would be multiplying our V₁ and V₂ by a common factor that would cancel out in division. All that matters is the ratio between the two volumes, which is the same whether the volumes are in mL or in L.

---

We follow the exact same procedure in the second question as we did in the first problem: solve for M₂ given M₁ = 9.02 M, V₁ = 35.0 mL, and V₂ = 45.0 mL:

[tex]M_2=\frac{M_1V_1}{V_2} = \frac{(9.02 \text{ M})(35.0 \text{ mL})}{45.0 \text{ mL}} \\ M_2 = 7.02 \text{ M}.[/tex]

Answers

Answer: It takes more energy to break the bonds of the reactants than is released when the  bonds in the products are formed

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat. Thus it takes more energy to break the bonds of the reactants than is released when the  bonds in the products are formed

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat. Thus More energy is released when the bonds in the products are formed than is used to  break the bonds in the reactants
