This question is incomplete because you lack the options. But it can be answered based on my knowledge.

Two types of mixture could be: homogeneous and heterogeneous

A mixture is a term that refers to the combination of two or more components joined but not chemically combined. Mixtures can be classified as follows:

  • Homogeneous: Are characterized by having a uniform texture and appearance, their components are not distinguished.
  • For example: water + grapes = wine

Homogeneous mixtures can be:

  • Solutions: The mixtures formed are characterized by being formed with components that do not react chemically with each other, but that can modify their physical properties when they become part of the solution.
  • For example: coffee + milk = Coffee

There are also Colloids, a type of mixture formed by particles of one or more substances that are dispersed in another substance called a dispersing medium.

  • For example Gelatin powder + Water = Gelatin.

They are the intermediate mixtures between homogeneous and heterogeneous.

  • Heterogeneous: Are mixtures in which it is possible to observe their components due to the discontinuity with the naked eye.
  • For example Milk + cereal = Cereal

What would be the pH of an H2SO4 solution if the [H+] = 4.58 x 10-5 moles/liter?
Ghella [55]

Answer: pH of an H_2SO_4 solution is 4.34

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

pH=-\log [H^+]

H_2SO_4\rightarrow 2H^++SO_4^{2-}

Putting in the values:

pH=-\log[4.58\times 10^{-5}]

pH=4.34

Thus pH of an H_2SO_4 solution if the [H^+] is 4.58\times 10^{-5}] is 4.34

Tails of phospholipids that don't like water
densk [106]
Those tails are called hydrophobic. You can note the etymology: hydro= water, phobi = fear, aversion, dislike.

Phospholipds' tail is a long non polar chain, made of Carbon and Hydorgens, that rejects water (a polar solvent) and is attracted to non-polar compounds (oil for example).  That is why that tails can atract dirt.

How many grams of solute are needed to make 37.5 mL of 0.750 M KI solution? Round to three significant digits.
Marysya12 [62]

4.648 gm of solute is needed to make 37.5 mL of 0.750 M KI solution.

Solution:  

We will start with the Molarity  

\text { Molarity }=\text { Mole of solute } \div \text { liter of solution }

Also we know 1000 ml = 1 L

Therefore 37.5 ml by 1000ml we obtained 0.0375L  

Equation for solving mole of solute

\text { Mole of solute }=\text { Molarity } \times \text { Liters of solution }

Now, multiply 0.750M by 0.0375

Substitute the known values in the above equation we get

0.750 \times 0.0375=0.0281

Also we know that Molar mass of KI is 166 g/mol

So divide the molar mass value to get the no of grams.

0.028 \times 166=4.648

So 4.648 gm of Solute is required for make 37.5 mL of 0.750 M KI solution.
