Which of the following is a homogeneous mixture?

Chemistry
1 answer:
Gala2k [10]4 years ago
5 0

Answer:

Water and applesauce are examples of a Homogeneous Mixture

Chicken Noodle Soup and Soil with Water would be examples of a Heterogeneous Mixture.

Explanation:

Homogeneous Mixtures are mixtures that are the same throughout, i.e. it's just one substance. A good example of this is a glass of water, this is because it is all one solution <u><em>without any other visible</em></u><u> </u><u><em>different parts</em></u><em> </em>that will settle if left alone for a while. The same applies to the applesauce, it is one type of a mixture with nothing else added to it.

Hetergeneous Mixtures on the other hand <u><em>are different substances </em></u>added together. The noodles, soup and chicken, three different substances in one mixture. The soil and water mixture also applies, two substances which separate if left alone.  

See http://chemistry.elmhurst.edu/vchembook/106Amixture.html#:~:text=A%20homogeneous%20mixture%20has%20the,gas%2C%20liquid%2C%20and%20solid. For more information.

Methylpropane (complete and condensed structural formulas)
Tcecarenko [31]

Answer:

Here's what I get  

Explanation:

1. Complete structural formula

Methylpropane consists of a chain of three carbons with another carbon atom attached to the middle carbon. Enough H atoms are added to give each C atom a total of four bonds.

The complete structural formula is shown below (There is a C atom at each intersection).

2. Condensed structural formula

A condensed structural formula is designed to be typed on one line.

The molecule has three CH₃ groups attached to a single carbon atom, so the condensed structural formula is  

(CH₃)₃CH

The formula is also often written CH₃CH(CH₃)CH₃ and as (CH₃)₂CHCH₃.

Within the nuclear us of individual Adams of the same element, the proton number
AnnyKZ [126]

the same

Explanation:

Within the nucleus of individual atoms of the same element, the proton number is the same.

All atoms of the same kind from the same element have the same number of protons.

The number of protons does not change, it remains fixed after a chemical reaction.

Different elements have different number of protons that typifies and makes them unique.

But atoms of the same element have the same number of protons in them.

A 50.0 mL sample of 12.0 M HCl is diluted to 200 mL. What is true about the diluted solution?
kobusy [5.1K]

The concentration of the solution reduces and the number of moles of solute isn't affected.

Data;

  • V1 = 50mL
  • C1 = 12.0M
  • V2 = 200mL
  • C2 = ?
<h3>Facts about the diluted solution</h3>

1. When the solution is diluted, the concentration changes and this time, the concentration reduces.

Using dilution formula

c_1 v_1 = c_2 v_2\\12 * 50 = c_2 * 200\\c_2 = \frac{600}{200} \\c_2 = 3M

The concentration of the solution reduces.

2. The number of moles remains the same.

When a solution is diluted, the number of moles remains the same because there's no change in the mass of the solute.

An air sample contains 0.044% CO2? If the total pressure is 750 mm Hg. What is the partial pressure of CO2?2?
Aleksandr [31]
Partial pressure=mole fraction×Pt
x=0.044÷44(maolarmass of CO2)×Pt
x=0.044÷(44)2×Pt
x=5×10^-4×Pt
x=5×10^-4×Pt
where Pt:1atm=760mmHg
xatm=750mmHg
750×1÷760=0.99
now;5×10^-4×099=4.95×10^-4.
Pt=4.95×10^-4
