The fuel used in many disposable lighters is liquid butane, C4H10. Butane has a molecular weight of 58.1 grams in one mole. How
BARSIC [14]
<h3>Answer:</h3>

              6.21 × 10²² Carbon Atoms

<h3>Solution:</h3>

Data Given:

                 Mass of Butane (C₄H₁₀)  =  1.50 g

                 M.Mass of Butane  =  58.1 g.mol⁻¹

Step 1: Calculate Moles of Butane as,

                 Moles  =  Mass ÷ M.Mass

Putting values,

                 Moles  =  1.50 g ÷ 58.1 g.mol⁻¹

                 Moles  =  0.0258 mol

Step 2: Calculate number of Butane Molecules;

As 1 mole of any substance contains 6.022 × 10²³ particles (Avogadro's Number) then the relation for Moles and Number of Butane Molecules can be written as,

            Moles  =  Number of C₄H₁₀ Molecules ÷ 6.022 × 10²³ Molecules.mol⁻¹

Solving for Number of Butane molecules,

             Number of C₄H₁₀ Molecules  =  Moles × 6.022 × 10²³ Molecules.mol⁻¹

Putting value of moles,

     Number of C₄H₁₀ Molecules  =  0.0258 mol × 6.022 × 10²³ Molecules.mol⁻¹

                 Number of C₄H₁₀ Molecules  =  1.55 × 10²² C₄H₁₀ Molecules

Step 3: Calculate Number of Carbon Atoms:

As,

                            1 Molecule of C₄H₁₀ contains  =  4 Atoms of Carbon

So,

          1.55 × 10²² C₄H₁₀ Molecules will contain  =  X Atoms of Carbon

Solving for X,

 X =  (1.55 × 10²² C₄H₁₀ Molecules × 4 Atoms of Carbon) ÷ 1 Molecule of C₄H₁₀

X  =  6.21 × 10²² Atoms of Carbon

Evaluate three communication skills that can assist you in sustaining positive relationships​
Tpy6a [65]

1. Accept and celebrate differences. One of the biggest challenges we experience in relationships is that we are all different. We can perceive the world in many ways. Certainly astumbling block that we come across when we try to build relationships is a desire or an expectation that people will think like we do and, in this way, it is so much easier to create a rapport. We feel more comfortable when we feel that people “get” us and can see our point of view. Life, however, would be very dull if we were all the same and, while we may find it initially easier, the novelty of sameness soon would wear off. So accepting and celebrating that we are all different is a great starting point.

2. Listen effectively. Listening is a crucial skill in boosting another person’s self-esteem, the silent form of flattery that makes people feel supported and valued. Listening and understanding what others communicate to us is the most important part of successful interaction and vice versa.

Active or reflective listening is the single most useful and important listening skill. In active listening, we also are genuinely interested in understanding what the other person is thinking, feeling, wanting, or what the message means, and we are active in checking out our understanding before we respond with our own new message. We restate or paraphrase our understanding of their message and reflect it back to the sender for verification. This verification or feedback process is what distinguishes active listening and makes it effective.

3. Give people your time. Giving time to people is also a huge gift. In a world where time is of the essence and we are trying to fit in more than one lifetime, we don’t always have the time to give to our loved ones, friends, and work colleagues. Technology has somewhat eroded our ability to build real rapport and we attempt to multi-task by texting and talking at the same time.

Being present in the time you give to people is also important, so that, when you are with someone, you are truly with someone and not dwelling in the past or worrying about the future. The connection we make with other people is the verytouchstone of our existence, and devoting time, energy, and effort to developing and building relationships is one of the most valuable life skills.

Why did the food coloring separate into different dyes?
Dmitrij [34]

It is a mixture

Explanation:

Food coloring is able to separate into different dyes because it just a simple mixture of different color pigments.

Under a chromatogram the different colors will migrate relatively over an absorbent.

A mixture is an impure substance with the following properties:

  • composition is indefinite as they are made up of two or more elements or compounds in any proportion by mass.
  • They are able to retain their identities i.e physical properties are maintained.
  • Their constituents reacts differently to changed conditions.
  • They can easily be separated into constituent by physical methods.
