Sodium stearate is the sodium salt of stearic acid. This white solid is the most common soap. It is found in many types of solid deodorants, rubbers, latex paints, and inks.

It is also a component of some food additives and food flavorings.

Sodium stearate is a stabilizer and thickener that helps harden soaps and deodorants, allowing a wide variety of shapes and sizes and removing the need for unnecessary packaging and synthetic preservatives.

It also has opacifying properties that give the foam a creamy white appearance.

Sodium stearate is a vegetable-based soap material sourced from coconut and palm oils. It is often referred to as a sodium salt that comes from stearic acid, a fatty acid that occurs naturally.

Common Ion Effect on Solubility

Adding a common ion decreases solubility, as the reaction shifts toward the left to relieve the stress of the excess product.

Adding a common ion to a dissociation reaction causes the equilibrium to shift left, toward the reactants, causing precipitation.

How many miles of NaCl are in 250 mL of a 0.4 M solution?​
creativ13 [48]

Answer:

There are 0.1 moles of solute in 250 mL of 0.4 M solution.

Explanation:

First, recognize that the molar concentration tells you how many moles of the solute are present in one liter of solution. In a 0.4 M solution, there are 0.4 moles of solute in every liter of solution. You can determine the number of moles of solute in 250 mL of the solution using dimensional analysis.

250 ml . 1L/1000 L . 0.4mol / 1L

Units of liters and milliliters cancel, leaving you with a final answer in units of moles, at 0.1 mol.

If the specific heat of a material is 0.416 J/(g°C) and sample absorbs 50 J when it is heated from 30°C to 50°C what is the mass
ololo11 [35]

The mass of the sample of the material is 0.1664 g.

<h3 /><h3>What is specific heat?</h3>

The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.

By the formula of specific heat

Q = mc \Delta T

Given, that the specific heat (c) of material is 0.416 J/gC

The difference in temperatures is 30°C to 50°C

The mass=?

Q = heat, 50 J

Putting the values in the equation

\rm 50\;J = m \times 0.416 J/g^\circ C \times (50 - 30)\\\\m = \dfrac{0.416 J/g^\circ C \times 20}{50} = 0.1664 g

Thus, the mass of the samples is 0.166 g.

90 grams of glucose, C6H12O6, is dissolved in 2 liters of solution. Determine the molarity (M).
Masja [62]

Answer:

0.25 M

Explanation:

The first step is to determine how many moles of glucose there are, which means first finding out the molar mass of glucose. Carbon has a molar mass of about 12, hydrogen 1, and oxygen 16, so the total molar mass of glucose is about 6(12)+12(1)+6(16)=180 grams. This means that 90 grams is half a mole. Half a mole of substance divided by two liters of solution is (1/2)/2=1/4, or a molarity of 0.25. Hope this helps!
