Answer:

To figure out which sample contains more KCl, information on the mass of chlorine in each mixture is needed; this can be found using the law of definite proportions.

Explanation:

The law of definite proportions explains that a chemical compound always contains the same proportion by mass of its elements. For example, a compound made of two elements maintains consistent ratios regardless of sample size.

By applying this law, one can calculate the ratios of sodium to chlorine in NaCl and potassium to chlorine in KCl if the chlorine mass is known. This lets us identify which mixture holds a larger percentage of KCl.

Answer:

Knowing the chlorine content in each mixture.

Explanation:

By determining the chlorine amount, you can calculate the relative quantities of potassium and sodium to identify which mixture has more KCl.

A saturated solution of potassium iodide contains, in each 100 mL, 100 g of potassium iodide. The solubility of potassium iodide
KiRa [2933]

Answer:

The specific gravity of the saturated solution is 2

Explanation:

Specific gravity represents the ratio of the density of a solution, in this case, a saturated potassium iodide (KI) solution, to the density of water. Assuming the density of water is 1:

Specific gravity  = Density

Density itself is defined as the mass divided by volume.

In 100mL of water, the mass of dissolve-able KI is:

100mL * (1g KI / 0.7mL) = 143g of KI

This indicates that all 100g of KI dissolves (Mass solute)

With 100mL of water corresponding to a mass of 100g (Mass solvent)

The overall mass of the solution computes to 100g + 100g = 200g

In a volume of 100mL, the solution's density is:

200g / 100mL = 2g/mL.

Specific gravity is a dimensionless quantity, thus the specific gravity of the saturated solution is 2

1. Use the following thermochemical equation.
KiRa [2933]

Answer:

There's a lot to address, so I'm uncertain if I can tackle this; it feels overwhelming. Perhaps you could simplify it for me as it's quite extensive.

Explanation:

  • I wish I had the answers.
  • It's too complex.
  • This chemistry isn't familiar to me.
  • If you have another chemistry-related question, feel free to ask.
  • This is just too difficult.

How many molecules of glucose are in 1 l of a 100 mm glucose solution?
castortr0y [3046]

The result is: 6.022·10²² molecules of glucose.

c(glucose) = 100 mM.

c(glucose) = 100 · 10⁻³ mol/L.

c(glucose) = 0.1 mol/L; concentration of the glucose solution.

V(glucose) = 1 L; volume of the glucose solution.

n(glucose) = c(glucose) · V(glucose).

n(glucose) = 0.1 mol/L · 1 L.

n(glucose) = 0.1 mol; quantity of substance.

N(glucose) = n(glucose) · Na (Avogadro's number).

N(glucose) = 0.1 mol · 6.022·10²³ 1/mol.

N(glucose) = 6.022·10²².

What is the absolute structural necessity for an alcohol to be oxidized with chromium trioxide?
castortr0y [3046]
For an alcohol to be oxidized, it cannot be a tertiary alcohol.

A tertiary alcohol features the -OH group bonded to a carbon that is also connected to three other carbon atoms. This configuration prevents the alcohol group from engaging in oxidation, which is why tertiary alcohols do not oxidize under mild conditions.
