4-How does the concentration of ions in a strong acid differ from a weak acid?

Answers

Answer 1
Strong acids have a higher percentage of H+ ions which means that they have a higher pH and will fully dissociate in water. Whereas weak acids have a lower percentage of H+ ions which means that their pH would be lower and they would only partially dissociate.

A student is attempting to identify an unknown liquid. She places 10 mL of the liquid in a test tube and begins heating it over a burner. She checks and records the temp every minute until it begins to boil. What is the independent variable?

Answers

Answer:

The time of heating

Explanation:

Let us analyse the experiment closely; the temperature of the liquid increases as the time of heating increases. This implies that the temperature of the liquid is dependent on the time of heating of the liquid. The longer the time of heating, the greater the increase in temperature until the boiling temperature is eventually attained.

Hence, the temperature of the liquid is the dependent variable, the time of heating is the independent variable when the heating rate is held constant.

What is electromagnetic radiation?

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

How many moles are there in 3.612 x 1024 formula units of Na2SO4?

Answers

Answer:

Theanswer is 6 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{3.612 \times {10}^{24} }{6.02 \times {10}^{23} } \\ [/tex]

We have the final answer as

Dana is trying to determine if an unknown sample is a pure substance or not. The sample has a cloudy white color, and it seems evenly mixed throughout. The sample is a liquid with high viscosity. Dana tried separating the sample with a magnet with no effect. When Dana filtered the sample, larger granules of the sample were left behind in the filter. What evidence allowed Dana to conclude that the sample is NOT a pure substance?


It has a cloudy white color.


The liquid has high viscosity.


Dana tried separating the sample with a magnet with no effect.


Dana filtered the sample and larger granules of the sample were left behind.

Answers

Answer:

Dana filtered the sample and larger granules of the sample were left behind.

Explanation:

If a substance is pure, it will have a uniform composition throughout. It will not separate into particles of various sizes.

One of the characteristics of pure substances is that they are homogeneous. A mixture is definitely made up of particles of various sizes.

Since the particles was filtered and larger granules were left behind, the sample has been separated by a physical method (filtration). Only a mixture can be separated by physical methods. It is not a pure substance.

What is Chemical formula ?

A chemical formula lists the elements that comprise the compound as well as the number of atoms of each element in the compound's smallest unit, whether a molecule or a formula unit. Knowing the elements' names and a few basic rules allows us to name simple compounds given a chemical formula.

Chemical formulas are classified into three types: empirical, molecular, and structural.

Empirical formulas depict the simplest whole-number ratio of atoms in a compound, whereas molecular formulas depict the number of each type of atom in a molecule and structural formulas depict how the atoms in a molecule are bonded to each other.

Thus, Formaldehyde, CH20, and acetic acid, C2H4O2, have the same empirical formula but different molecular formulas, option D is correct.

1 mol of titanium,
Ti, is 47.88 g is that true?

Answers

Answer: True.

Explanation:

Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.

The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. The molar mass of NaCl is 58.44 g/mol.
