Why is your body going through physical and chemical changes?

Answers

Answer 1

Answer:

Physical and chemical changes can occur almost everywhere, even in our bodies! Food must be broken down into a form that our cells can use. When we eat, our bodies physically break down food into small pieces. Our bodies also chemically break down those small pieces of food into tiny organic molecules.

3. What do you notice about the temperature of the substance in the test tube after it is placed in the beaker of water?
A)The temperature of the substance remains the same as it sits in the beaker of water.
B) The temperature of the substance decreases as it sits in the beaker of water.
C) The temperature of the substance increases as it sits in the beaker of water.

Answers

Answer:

C: The temperature of the substance increases as it sits in the beaker of water

Explanation:

This question was taken from a video where an attempt was made to investigate the changes in temperature when a substance undergoes change from it's solid phase to its liquid phase.

To do this, as seen in the video online, it shows a solid substance in a test tube being placed in a beaker of water.

From observation, the water in the beaker has a warmer temperature than the solid substance present in the test tube and this in turn makes the test tube gradually increase in temperature.

Thus, the solid substance will as well increase increase in temperature when it is placed in the beaker of water.

The gas in the discharge cell of a laser contains (in mole percent) 11% CO2, 5.3% N2, and 84% He. (a) What is the molar mass of this mixture

Answers

Answer:

[tex]MM_{mixture}=9.68g/mol[/tex]

Explanation:

Hello!

In this case, since the molar mass of gaseous mixtures can be determined via a weighted average containing the molar mass of each gas and the mole fraction (mole percent divided by 100) as shown below:

[tex]MM_{mixture}=x_{CO_2}M_{CO_2}+x_{N_2}M_{N_2}+x_{He}M_{He}[/tex]

Now, we plug in to obtain:

[tex]MM_{mixture}=0.11*44g/mol+0.053*28+0.84*4\\\\MM_{mixture}=9.68g/mol[/tex]

Balance the chemical equation below using the smallest possible whole number stoichiometric coefficients. FE2O3(s) Fe(s) O2(g)

Answers

Answer:

2Fe₂O₃(s) → 4Fe(s) + 3O₂(g)

Explanation:

The unbalanced reaction is:

Fe₂O₃(s) → Fe(s) + O₂(g)

To balance the oxygen atoms, we put a 2 before Fe₂O₃ and a 3 before O₂(g) - so as to make the total of O atoms in both sides 6 -:

2Fe₂O₃(s) → Fe(s) + 3O₂(g)

There are four Fe atoms on the left side and only one on the right side, so we put a 4 before Fe(s):

2Fe₂O₃(s) → 4Fe(s) + 3O₂(g)

Now the equation is balanced: there is an equal number of both Fe and O atoms in both sides of the equation.

Answers

Answer:

Even in a dry desert environment, the water cycle is taking place. The winds here blow up snow from the land and put it into the atmosphere, which is part of the water cycle. And the sun helps out, too, causing sublimation to occur, which causes snow to evaporate directly into water vapor gas

Describe the process of freezing ice cream in terms of heat flow.

Answers

Answer:

Freezing the mix is one of the most important operations in making ice cream, for upon it depend the quality, palatability, and yield of the finished product. Typically, freezing of ice cream is accomplished in two steps: (1) dynamic freezing, where the mix is frozen quickly while being agitated to incorporate air and to limit the size of ice crystals formed; and (2) static freezing, where the partially frozen product is hardened without agitation in a special low-temperature environment designed to remove heat rapidly. Although these steps primarily encompass freezing, or the formation of ice crystals, there are several other important processes that take place during this time that significantly impact the quality of ice cream. Both the dispersion of air bubbles and rearrangement of fat globules occur during the freezing steps.

Which of the following best describes a galvanic cell?
A. Abattery that requires energy to charge it
B. A battery containing an acid and a base
C. A battery containing a spontaneous redox reaction
D. A battery containing a nonspontaneous reaction

Answers

Answer:

Your answer is C

Explanation:

The option that best describes a galvanic cell is that a battery containing a spontaneous redox reaction. That is option C.

A Galvanic cell is simply defined as an electrochemical cell that uses the movement of electrons in a reduction-oxidation reaction to produce electrical energy for use.

A Galvanic cell is a battery and is made up of a conducting electrolyte solution and two halve cells which include:

one half-cell of metal A(anode) electrode andone half-cell of metal B(cathode) electrode.

In the galvanic cell a spontaneous redox reaction occurs which involves the transfer of electrons from anode to cathode with the release of energy.

Therefore, the option that best describes a galvanic cell is that it is a battery containing a spontaneous redox reaction.

if an atom with a mass number of 27 has 14 neutrons,it is an isotope of which element​

Answers

Answer:

the number of neutrons in above isotope = A - Z = 27 - 13 = 14. Note: The molar mass of aluminium, which is average of atomic masses of all isotopes = 26.981538 g/mol, since 13Al27 is the major isotope.

Explanation:

   

Answer:

Aluminum

Explanation

mass number = number of protons + number of neutrons

Number of protons = mass number - number of neutrons

No of protons = 27-14 = 13

Aluminum contains 13 protons

A compound is found to contain 25.24 % sulfur and 74.76 % fluorine by weight. To answer the questions, enter the elements in the order presented above. 1. What is the empirical formula for this compound

Answers

Answer:

[tex]SF_5[/tex]

Explanation:

Hello!

In this case, when determining empirical formulas by knowing the by-mass percent, we can first assume we have 25.24 g of sulfur and 74.76 g of fluorine, so we compute the moles:

[tex]n_S=25.24g*\frac{1mol}{32.07g} =0.787mol\\\\n_F=74.76g*\frac{1mol}{19.00g}= 3.935mol[/tex]

Now, we divide the moles of both S and F by the fewest moles, in this case, those of S in order to determine the subscripts in the empirical formula:

[tex]S=\frac{0.787}{0.797}=1 \\\\F=\frac{3.935}{0.797}=5[/tex]

Therefore, the empirical formula is:

[tex]SF_5[/tex]
