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.

Answer: Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely.

Explanation:

That is an ionic bond.

Explanation:

It has cations and anions

Answer: In a pure metal, there are atoms that are surrounded by free moving valence electrons in which they move from one part of metal to another part . There for we can conclude that pure metals are held together by things called metallic bonds and due to attraction between the mobile valence electrons and the positively charged metal ions.

Explanation:

The ability to be drawn into thin sheet is called malleability. The ability to be drawn into thin wires is called ductility. Therefore, the metallic bonds is between metals and metals.

Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions.

Covalent bonds are not strong bond. They can not have malleability and ductility. Ionic bonds are very strong bond. These are too not malleable or ductile. Lewis structure is used to show valence electron of every element in a molecule so, it has nothing to do with malleability and ductility. Due to metallic bonding, there is high melting and boiling point.

Therefore, the metallic bonds is between metals and metals.

1) H - hydrogen - 1.100797

2) HE - helium - 4.00260

3) LI - lithum -6.941

Explanation:

On the periodic table the mass of carbon is reported as 12.01 amu. This is the average atomic mass of carbon. No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu.

Answer:

its D. answers many questions about atoms.

The modern-day quantum model of the atom is better than John Dalton’s model because it "  answers many questions about atoms."

This concept also referred to as the quantum mechanical and wave mechanical model, would be the cornerstone of contemporary atomic theory. The fact that an electron inside an atom may only exist in a limited range of states or energy is analogous to a standing wave.

Dalton proposed that the concept of atoms will be used to explain the laws of conservation of mass as well as definite proportions. Imagining atoms as "solid, massy, hard, impenetrable, moving objects," he claimed that almost all matter would be composed of these tiny, indivisible particles.

Dalton also stated that almost no atom might be formed, converted into another, as well as destroyed. The complex shapes of orbitals also known as electron clouds used in the quantum mechanical atomic model are areas of space where an electron is likely to be present. So rather than being based on certainty, this model would be probability based.

Therefore, the correct answer will be option (D)

Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

A chemical reaction is said to have occurred when new substances are formed. The reaction between magnesium chloride  solution and sodium carbonate solution is a double decomposition reaction since the cations exchange anion partners in the product;

MgCl2(aq) + Na2CO3(aq) ------> MgCO3(s) + 2NaCl(aq)

We must note that a single replacement reaction depends on the relative positions of metals in the electrochemical series. Al can react with CuCl2 because Al is more reactive than copper and ahead of Cu in the electrochemical series. On the other hand, Mg is ahead of Al in the electrochemical series and more reactive than Al hence Al does not react with MgCl2.

To solve such this we must know the concept of acid and base reaction. Therefore, the concentration of acid decides the concentration of hydrogen gas evolved.

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

When creating mixture the amount of hydrogen gas is directly related to the concentration of the acid mixture, the higher the concentration level The more hydrogen gas would be produced.

Therefore, the concentration of acid decides the concentration of hydrogen gas evolved.

Answer:

droplets of sulfuric acid

Explanation:

First, the amount of sunlight received at a given latitude is important. At the equator, the sun is high in the sky and thus very intense. As you move away from the equator, the sun does not reach as high of an angle in the sky, and is less intense. Another important effect near the poles is that during the summer, the sun is up all the time, which boosts the total amount of sunlight received in a day, while in contrast, during the winter, no sunlight is received at all.

There is another, more subtle effect that has to do with latitude. Nature likes to have the temperature be the same everywhere, much like ice cream melts at room temperature or a hot cup of coffee cools to room temperature. The equator is getting blasted with intense sunlight, while the poles are getting a lot less. Nature tries to resolve this imbalance and make the atmosphere the same temperature everywhere. The most efficient way to transfer heat towards the poles depends on latitude and the rotation of the Earth in a complex way. In the tropics (within 30 degrees latitude of the equator), the average daily temperature is mostly constant. Whether you move from north to south, say fro the equator to Mexico, the temperature is mostly the same. Compare that to the midlatitudes (30–60 degrees latitude), where the temperature changes rapidly as you move north or south to the poles. For example, the temperature in Texas is a lot hotter than the temperature in North Dakota.

Another factor is the composition of the surface. Different substances absorb, store, and re-emit heat with different levels of efficiency. The ocean is a major factor, which can either warm or cool the adjacent land. Other surface materials like rock, sand, vegetation, and ice also regulate temperature

The elevations of the surface, specifically mountains effect the climate. Usually, the taller the mountain, the colder the temperature is at the top. Mountains also cause air to flow in certain ways around them, which leads to wet areas on the upwind side and dry areas on the downwind side.

Answer:

M-A=N

Explanation:

M-A=N

Here is an example.

The equation above means that the atomic number (A) subtracted from the average atomic mass (M) equals the combined amount of neutrons and protons. Since we know that 35 17Cl is Chlorine (this is because Chlorine (Cl) is the 17th number on the periodic table and has the average atomic mass of 35), we can insert our data into the equation and end up with the following:

35-17=18.

From here, we can tell that we have a mix of neutrons and protons, with the total being 18. Since the atomic number is 17, we can reasonably assume that there are 17 protons and 1 neutron.

But we still need to find the number of electrons. Fortunately, the number of electrons is always equivilant to the number of protons and the atomic mass, so we know that the number of electrons is 17.

So, we have;

17 Protons

1 Neutron

17 Electrons
