When doing integrated rate law calculations for second order reactions, we are assuming a rate law that resembles:______.

Answer:

D. 4

Explanation:

Answer:

The correct option is;

D. Calcium chloride breaks into 3 ions, while sodium chloride only breaks into 2 ions

Explanation:

To help melt the ice on icy streets, calcium chloride (CaCl₂) is a more preferred salt type to sodium chloride (NaCl) as when it dissociates into ions in the ice, it forms three ions: a calcium ion, Ca²⁺, and two chloride ions, 2 Cl⁻, while sodium chloride forms two ions: one sodium ion, Na⁺, and one chloride ion, Cl⁻

According to the freezing point depression equation, we have;

ΔT = \(K_f\) × m × i

Where;

ΔT = Change in freezing point temperature

\(K_f\) = The freezing point depression constant

m = The solution's molality

i = van't Hoff factor

The calcium chloride salt will cause the most depression because the van't Hoff factor is 3 for calcium chloride and 2 for sodium chloride.

Answer:

Density = 8.92 g/cm³

Explanation:

Density shows the relation of the mass and volume of a determined object. We have this deffinition:

Density = mass / volume

First of all, we calcualte the volume of the block of copper metal, with the data given:

8.4 cm . 5.5 cm . 4.6 cm = 212.52 cm³

Now we replace at the density formula:

Density = 1896 g /212.52 cm³  = 8.92 g/cm³

Preservation Techniques

Adding large amounts of salt or sugar to foods creates a hypertonic environment for bacteria, causing plasmolysis.

Pickling, smoking, and drying foods have been used for centuries to preserve foods.

Osmotic pressure is never a sterilization technique.

The preservation techniques and their effects on bacteria can be elaborated as follows:

Adding large amounts of salt or sugar to foods creates a hypertonic environment for bacteria, causing plasmolysis. This means that the high concentration of solutes outside the bacterial cells causes water to flow out of the cells, leading to cell shrinkage and ultimately inhibiting bacterial growth.

Pickling, smoking, and drying foods have been used for centuries to preserve foods. These methods work by either removing moisture, adding preservatives, or changing the food's environment, all of which help to slow down or prevent the growth of bacteria and spoilage.

Osmotic pressure is never a technique used for food preservation and sterilization; rather, it's a concept related to the movement of water across a semipermeable membrane in response to differences in solute concentrations. However, the principle of osmotic pressure can help us understand how some preservation techniques, such as adding salt or sugar, work by creating a hypertonic environment that leads to plasmolysis in bacteria.

Answer:

When 156.32 g of barium hydroxide is reacted, approximately 142.34 g of aluminum hydroxide can be produced, based on the balanced chemical equation and stoichiometry.

To determine the amount of aluminum hydroxide that can be produced when 156.32 g of barium hydroxide is reacted, we need to consider the balanced chemical equation for the reaction and use stoichiometry.

The balanced chemical equation for the reaction is:

Ba(OH)2 + 2AlCl3 → 2Al(OH)3 + 3BaCl2

From the balanced equation, we can see that for every 1 mole of Ba(OH)2, 2 moles of Al(OH)3 are produced.

First, we need to calculate the number of moles of barium hydroxide (Ba(OH)2) in 156.32 g:

Molar mass of Ba(OH)2 = (137.33 g/mol + 2(16.00 g/mol + 1.01 g/mol)) = 171.34 g/mol

Moles of Ba(OH)2 = mass / molar mass = 156.32 g / 171.34 g/mol = 0.911 mol

Now, using the stoichiometry of the balanced equation, we can determine the moles of aluminum hydroxide (Al(OH)3) produced:

Moles of Al(OH)3 = 2 × Moles of Ba(OH)2 = 2 × 0.911 mol = 1.822 mol

Finally, to convert the moles of aluminum hydroxide to grams, we need to multiply by the molar mass of Al(OH)3:

Molar mass of Al(OH)3 = (26.98 g/mol + 3(16.00 g/mol + 1.01 g/mol)) = 78.00 g/mol

Mass of Al(OH)3 = Moles of Al(OH)3 × molar mass = 1.822 mol × 78.00 g/mol = 142.34 g

Therefore, when 156.32 g of barium hydroxide is reacted, approximately 142.34 g of aluminum hydroxide can be produced.

\(AlP_2O_6\)  is the empirical formula for the substance.

The simplest whole number ratio of atoms from each component element is the empirical formula for a compound. Find the moles of each element present in the compound so that we may derive the empirical formula. To do this, we need to convert the percentages of each element to the amount in moles.

First, convert the percentages of each element to grams. Since the percentages add up to 100%, we can use 100 grams as the total mass of the compound:

Aluminum: 15.9% × 100 g = 15.9 g

Phosphorus: 27.4% × 100 g = 27.4 g

Oxygen: 56.6% × 100 g = 56.6 g

Next, convert the mass of each element to moles by dividing by the molar mass of each element:

Aluminum: \(\frac{15.9 g }{ 26.98 g/mol }= 0.59 mol\)

Phosphorus: \(\frac{27.4 g }{30.97 g/mol} = 0.89 mol\)

Oxygen: \(\frac{56.6 g }{ 16.00 g/mol} = 3.53 mol\)

Now, divide each mole value by the smallest value (0.59 mol):

Aluminum :  \(\frac{ 0.59 mol }{0.59 mol} = 1\)

Phosphorus: \(\frac{0.89 mol }{ 0.59 mol }= 1.5\)

Oxygen :  \(\frac{ 3.53 mol}{ 0.59 mol} = 5.97\)

To get the simplest whole number ratio, we need to round each ratio to the nearest whole number.

Hence, the compound's empirical formula is \(AlP_2O_6\).

Alkaline earth metals will react in a 1:1 ratio with group 16 nonmetals to generate a compound.

Our two ratios would combine. As a result of their greater positive charge and smaller iniquity. Compared to alkali metals, alkaline earth metals have a significantly stronger tendency to form a complex with the Lewis base.

Alkali metals, which contain a single valence electron, and the halogens react aggressively. The two components come together to create salt. For instance, the reaction between the alkali metal sodium (Na) and the halogen chlorine (Cl) yields table salt, or sodium chloride (NaCl).

The group 1 element Li, Na, K, Rb, Cs, and Fr are alkali metals. When sliced, the alkali metals are all supple, metallic, and lustrous.

As an illustration, each member of Group 1 surrenders one electron to become a 1+ cation. A 1- anion can be created by adding one electron to any element in Group 17. Ionic compounds can be created when elements from Groups 1 and 17 mix one to one.

When ammonium hydroxide (NH4OH) is added to copper(II) sulfate (CuSO4), the equilibrium shifts due to the formation of a complex ion.

The reaction can be represented as follows:
CuSO4 (aq) + 4NH4OH (aq) → [Cu(NH3)4(H2O)2]SO4 (aq) + 4H2O (l)
In this reaction, the copper(II) ions (Cu²⁺) from CuSO4 form a complex ion with ammonia (NH3) from NH4OH, creating [Cu(NH3)4(H2O)2]²⁺. This results in a decrease in the concentration of Cu²⁺ ions in the solution. To maintain equilibrium, the reaction shifts towards the right, according to Le Chatelier's Principle, favoring the formation of more complex ions and consuming more CuSO4.
