Answer:

A) HF (Hydrofluoric acid)

Explanation:

dw I gotchu. So first off there are three types of intermolecular forces of attraction: 1) London-Dispersion, 2) Dipole-Dipole, 3) Hydrogen-Bonding Attraction Forces. That is also ranked in increasing strength, with Hydrogen-Bonding Attraction Forces being the strongest. Every molecule has London-Dispersion forces present and all the diatomic molecules listed have dipole moments of a certain debye (or Coloumb-meter) value. Both are irrelevant here so dw about that. Lets look at the strongest attraction: the hydrogen-bonding one. Now, don't get confused bc all of these acids are bonded to H bc hydrogen-bonding attraction forces only occur when H is bonded to N, O, or F. So Process of Elimination, hydrofluoric acid (HF) has the strongest intermolecular forces of attraction.

Note: If you don't know what inter/intra molecular forces of attraction are, ill give u a quick summary. Intermolecular refers to electrostatic attractions between molecules while intramolecular refers to the actual bonds, single, double, or triple, binding the atoms together. Well there you have it, have a great day. :)

Answer:

The oxidation number for sulfur in SO2 is +4.

Explanation:

To find the oxidation number of sulfur, it is simply a matter of using the formula SO2 and writing the oxidation numbers as S = (x) and O2 = 2(-2) = -4. Using the rule and adding the oxidation numbers in the compound, the equation becomes x +(-4 ) = 0. Solving for x, it is evident that the oxidation number for sulfur is +4.

Answer:

it is because of Dark Matter

Dark Matter, component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).

Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly.

A group of scientists is studying observable matter in a cluster of galaxies. The duster remains intact due to the gravitational pull.

A galaxy is a collection of stars, stellar remains, interstellar gas, dust, and dark matter that are gravitationally bonded together.

Dark matter is a component of the universe whose gravitational pull can be detected rather than its luminosity. The universe's matter-energy ratio is made up of 30.1 percent dark matter, 69.4 percent dark energy, and “regular” visible matter (0.5 percent).

Since dark matter is made up of particles that do not absorb, reflect, or emit light, it is impossible to identify it through electromagnetic radiation observation. Dark matter is a substance that cannot be directly observed.

Therefore, a team of researchers is examining the material that can be seen in a clump of galaxies. Due to the gravitational force, the duster is unharmed.

Answer:

I have no Idea please give more context to your question.

Explanation:

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.

Sulfuric acid undergoes dissociation reaction to produce twice the amount

of hydrogen ions produced by nitric acid in solution.

Reasons:

The concentration of the analytical group = 0.2 M

Volume of reagent = 20 ml

Concentration of the nitric acid to be replaced = 0.1 M

Replacement for the nitric acid = Sulfuric acid

Concentration of the sulfuric acid = Concentration of the nitric acid = 0.1 M

Reaction = Titration

Solution:

Sulfuric acid in solution gives; H₂SO₄ (aq)  ⇄ 2H⁺ (aq) + SO₄²⁻(aq)

For nitric acid, we have; HNO₃ (aq) ⇄ H⁺(aq) + NO₃⁻(aq)

Therefore;

1 mole of sulfuric acid gives 2 moles of hydrogen ions

0.1 M solution of sulfuric acid gives 0.2 moles of hydrogen ions per liter

0.1 moles of hydrogen ions are therefore present in half a liter solution of 0.1 M sulfuric acid solution.

However;

0.1 M of nitric acid gives 0.1 moles of hydrogen ions per liter

Therefore;

Answer:

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.

Percent by mass=  mass of solute/mass of solution * 100

Explanation: work out the equation

Answer:

136000 J or 136 kJ

Explanation:

Formula

Heat = m * c * deltaH

Givens

m= 0.5 kg

c = 3400 J / (kg * oC)

Deltat = (100oC – 20oC)

deltat = 80oC

Solution

Heat = 0.5 kg * 3400 J/(kg* oC) * 80oC

Heat = 136000 Joules

Heat = 136 kg

Considering the reaction stoichiometry, the correct answer is second option: the total number of moles of water produced from 13. 35 mol of oxygen is 26.7 moles.

The balanced reaction is:

2 H₂ + O₂ → 2 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 1 moles of O₂ produce 2 moles of H₂O, 13.35 moles of O₂ will produce how many moles of H₂O?

[tex]amount of moles of H_{2} O=\frac{13.35 moles of O_{2} x2 moles of H_{2} O}{1 mole of O_{2}}[/tex]

amount of moles of H₂O= 26.7 moles
