Answers

Answer 1

The molar solubility of AgBr in a 5.00 M NH3 solution is the 5.29 x [tex]10^{-2[/tex] M.

The first step is to write the equilibrium equation for the dissolution of AgBr in [tex]NH_3[/tex]:

AgBr(s) + [tex]2NH_3(aq)[/tex] ⇄ [tex]Ag(NH_3)_2[/tex]+(aq) + Br-(aq)

Next, we need to calculate the equilibrium constant for this reaction using the Kf value given as below:

Kf = [Ag[tex][NH_3]^2[/tex]+] [Br-] / [AgBr] [tex][NH_3]^2[/tex]

Rearranging this equation gives:

[AgBr] = Kf [Ag[tex](NH_3)_2[/tex] +] [tex][NH_3]^2[/tex] / [Br-]

Plugging in the given values and solving gives:

[tex][AgBr] = (1.7 * 10^7) [Ag(NH3)2+] [NH3]^2 / 5.4 * 10^{-13} \\[/tex]

[AgBr] = 5.29 * [tex]10^{-2}[/tex] M

Therefore, the molar solubility of AgBr in a 5.00 M [tex]NH_3[/tex] solution is 5.29 * [tex]10^{-2}[/tex] M.

Magnesium and calcium have similar chemical properties because their atoms in the ground state have.

Answers

Magnesium and calcium have similar chemical properties because they have the same number of electrons in their valence shells.

What does magnesium and calcium have in common?

The valence/outermost shell of magnesium and calcium both has two electrons. An element's chemical characteristics are dictated by how its electrons are arranged in their orbits around the nucleus. The same number of protons and electrons means that an element's chemical behavior is fundamentally determined by its atomic number, which explains why Mg and Ca share the same chemical properties.

On the periodic table, magnesium and calcium are both located in the second vertical column. Magnesium and calcium are alkaline earth metals, just like all Group 2 elements.

The book value of a machine, as shown on the balance sheet, is not relevant in a decision concerning the replacement of that machine by another machine: TRUE

What is the book value?Book value is the worth of an asset based on its balance sheet account balance in accounting. The value of an asset is determined by subtracting the asset's original cost from any depreciation, amortization, or impairment expenses. Traditionally, a company's book value is equal to its total assets minus intangible assets and liabilities. In practice, however, depending on the source of the computation, book value may include either goodwill or intangible assets, or both. The value inherent in its employees, which is part of a company's intellectual capital, is always overlooked. When intangible assets and goodwill are specifically omitted, the indicator is frequently defined as "tangible book value."

That is the mechanical advantage of any machine is equal to the ratio between the output force and the input force.

Mechanical advantages M.A. = Input force / Output force

predict the theoretical mass of baco3 that should form

Answers

A precipitation reaction occurs when 50. 0 mL of 0. 50 M BaCl₂ is mixed with 75. 0 mL of 0. 75 M Na₂CO₃ (aq). The only precipitate is the BaCO₃ (s) formed. (a) The balanced chemical equation is BaCl₂ + Na₂CO₃ → BaCO₃ + 2NaCl. (b) The limiting reagent is Na₂CO₃.

What is Balanced Chemical Equation ?

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now we have to write the balanced equation

BaCl₂ + Na₂CO₃ → BaCO₃ + 2NaCl

How to find the number of moles ?

To calculate number of moles when molarity and volume are given as:

Number of moles = Molarity × Volume

Now,

Number of moles of BaCl₂ = Molarity  × Volume

                                             = 0.50 M  × 0.05 L         [1 ml = 0.001 L]

                                             = 0.025 moles

Number of moles of Na₂CO₃ = Molarity  × Volume

                                                = 0.75 M × 0.075 L     [1 ml = 0.001 L]

                                                = 0.05625 moles

The limiting reagent is Na₂CO₃ here.

Thus from the above conclusion we can say that A precipitation reaction occurs when 50. 0 mL of 0. 50 M BaCl₂ is mixed with 75. 0 mL of 0. 75 M Na₂CO₃ (aq). The only precipitate is the BaCO₃ (s) formed. (a) The balanced chemical equation is BaCl₂ + Na₂CO₃ → BaCO₃ + 2NaCl. (b) The limiting reagent is Na₂CO₃.

Answer:

See below.

Explanation:

Acceleration is the change in velocity over a period of time.  

Let vi be the initial velocity.

Let vf be the final velocity.

t is the time it took to go from vi to vf.

Acceleration is (vf-vi)/t

If the initial velocity was 2 cm/s and the final velocity was 10 cm/s, the object would have incresed it's velocity by (10 - 2) or 8 cm/s.  If iit took 10 seconds to reach vf, the acceleration would be:
