A. Burning a candle
B. Leaving a bicycle outside to rust
C. Bending sheet metal
D. Toasting a slice of bread

Answers

D which is Toasting a slice of bread

Answer:

C.  Bending sheet metal.

Explanation:

The metal is still intact.  No change in chemical bonds have occurred.

Burning a candle is converting wax into heat, CO2 and carbon soot.

A rusting bicycle is converting goof iron, Fe, into iron oxide (rust, Fe2O3)

Toasting bread is more difficult to define.  If the bread is just warmed, then it is physical.  If it is toasted (browned/burned), then a few surface molecules have been converted into tasty carcinogens, my favorite poison.

the bradford assay only works at low protein concentrations

Answers

Answer:

Dilute the sample

Explanation:

The statement is not entirely accurate. The Bradford assay is commonly used to determine protein concentrations in a sample.

However, it is true that the Bradford assay is more accurate and reliable for measuring protein concentrations at low to moderate levels rather than at very high concentrations.

The Bradford assay is based on the binding of Coomassie Brilliant Blue dye to proteins. The dye undergoes a color change from brown to blue when bound to proteins, allowing for the measurement of protein concentrations. At low protein concentrations, the binding of the dye to proteins is well-calibrated and results in a linear relationship between protein concentration and color intensity, making it suitable for accurate quantification.

At high protein concentrations, the binding capacity of the dye may become saturated, leading to non-linear and less accurate measurements. The excess protein can also cause interference and affect color development. In such cases, dilution or alternative protein quantification methods may be more suitable, such as the BCA assay or the Lowry assay.

Therefore, while the Bradford assay can be used to measure protein concentrations across a range of concentrations, it is generally more reliable for low to moderate protein concentrations.

A compound has a molar mass of 163.59 g/mol. If you have 736.155 grams of this compound, how many moles do you have?

Answers

Answer:

4.50000 moles

Explanation:

This is dimensional analysis. If there is 163.59 grams in 1 mole of this compound then the converse is true: in 1 mole of this compound there is 163.59 grams --> 1 mol/163.59 grams.

Now that you have your conversion factor:

736.155 grams * (1 mol/163.59 grams) is your equation.

When you multiply these together, grams cancel and you end up with the desired mole-based answer:

4.50000 moles (The extra zeros are to make up for the 6 significant figures in 736.155, feel free to omit them if necessary.)

two samples of solids have similar reactivity with acids and similar densities. their masses and volumes, however, are not at all similar. is it possible that these are the same substance?

Answers

Given that the volume and mass of a substance are not defining properties, it is entirely possible for two samples with different volumes and mass to be the same substance.

What are defining properties of a substance?These are properties that can help us to identify a substance. The most useful of which tend to be chemical properties such as reactiveness or melting points. Colors and density can also offer the insight needed to identify elements and substances. Mass and volume are not properties of a substance given that they can change often depending on the sample size and thus do not help to identify a substance.

Therefore, since the volume and mass of a substance are not defining properties of a substance, we can confirm that it is entirely possible for two samples with different volumes and mass to be the same substance.

The balanced equation shows how sodium chloride reacts with silver nitrate to form sodium nitrate and silver chloride. NaCl AgNO3 Right arrow. NaNO3 AgCl If 4. 00 g of NaCl react with 10. 00 g of AgNO3, what is the excess reactant? AgCl NaCl AgNO3 NaNO3.

Answers

The reactant that has been present in excess in the reaction has been NaCl. Thus, option B is correct.

The balanced chemical equation has been:

[tex]\rm NaCl\;+\;AgNO_3\;\rightarrow\;NaNO_3\;+\;3\;AgCl[/tex]

From the balanced equation, for complete utilization of 1 mole of sodium chloride, 1 mole of silver nitrate has been used.

The moles of can be given as:

[tex]\text Moles\;=\;\dfrac{m}{mwt}[/tex]

Where, mass of Silver nitrate, [tex]m=10\;\text g[/tex]

Molecular mass of silver nitrate, [tex]mwt=168\9.87\;\text {g/mol}[/tex]

Substituting the values, moles of silver nitrate has been:

[tex]\rm Moles \;AgNO_3=\dfrac{10}{169.87} \\Moles \;AgNO_3=0.058\;mol[/tex]

Mass of sodium chloride, [tex]m=4\;\text g[/tex]

Molecular mass of sodium chloride, [tex]mwt=58.44\;\text {g/mol}[/tex]

Substituting the values, moles of sodium chloride has been:

[tex]\rm Moles\;NaCl=\dfrac{4}{58.44}\\Moles\;NaCl=0.068\;mol[/tex]

From the balanced chemical equation,

[tex]\rm 1\;moles\;AgNO_3=1\;moles\;NaCl\\0.058\;mol\;AgNO_3=0.058\;mol\;NaCl[/tex]

Since, the available moles of NaCl has been 0.06 mol, and used NaCl has been 0.05 mol. Thus, NaCl has been the excess reactant.  Hence, option B is correct.

A Herbig-Haro (HH) object is:_:_________.
a. a small galaxy just outside the outer edge of the Milky Way
b. where a jet from a star in the process of being born collides with (and lights up) a nearby cloud of interstellar matter
c. a part of a giant molecular cloud where molecules containing two hydrogen atoms form
d. a star that has too little mass to start fusion in its core
e. cluster of very low-mass stars, observable only with infrared radiation

Answers

Given what we know about Herbig-Haro (HH) objects, we can confirm that they are born from the collision between a jet from a star and clouds of interstellar matter.

What are Herbig-Haro (HH) objects?To put it simply, a Herbig-Haro (HH) object is what we observe as a bright spot in distant space. Upon closer observation we can observe that these giant bright patches are not lone objects, but in fact immense groups of interstellar matter.

How Herbig-Haro (HH) objects are formed.The formation of one of these interstellar groups requires an immense amount of energy. This energy come from the speed at which the materials that form these objects collide.As stated in the question, the jet released from a star in the process of being born smashes into a giant cloud of dust and interstellar material to form the Herbig-Haro (HH) objects. This collision happens at hundreds of km/s. To put it into perspective, it would be roughly 500,000 miles per hour.

Therefore, we can confirm that option b, which states, "where a jet from a star in the process of being born collides with (and lights up) a nearby cloud of interstellar matter", is the correct choice for the question pertaining to Herbig-Haro (HH) objects.
