an unknown compound containing tellurium and bromine is analyzed and it is determined that 28.53% of the compound by mass is composed of tellurium. what is the mass percent of br in the compound?

Answers

Answer 1

The mass percent of bromine in this tellurium and bromine compound is 71.47%.

If the compound is made up only of tellurium and bromine, then if the mass percent of tellurium is 28.53%, we can safely assume that the rest is bromine. So, we take the 100% and subtract the mass percent of tellurium to calculate the mass percent of bromine:

100% - 28.53% = 71.47%

The mass percentage of bromine in this compound is 71.47%.

We can even use this data and the molar masses of tellurium and bromine to calculate the empirical formula of the compound if needed.

What is the density?

Answers

Answer:

Density = mass/volume (g/cm³)

First find the volume of the stone by subtracting the readings of the measuring cylinder.

Each unit is 4 ml. Take the reading where the lowest point of the curve of the liquid sits.

The first measuring cylinder reading is 24 ml.

The second measuring cylinder reading is 60 ml.

Volume of stone = 60 - 24 = 36 ml

Make sure the units are appropriate. Convert when necessary. ml and cm³ are the same so there is no need to convert. (36 ml = 36 cm³)

Density = 40/36 = 1.11 g/cm³

What is the law that is responsible for having the same number and type of atoms present in the reaction at the beginning and at the end?.

3. If an acid has a pH of 2, what is its [H*]?

Answers

If an acid has a pH of 2, then [H⁺] of the given acid is 100.

What is an acid?

An acid is a molecule or ion that may either donate a proton (i.e. hydrogen ion, H+) as a Brnsted-Lowry acid or establish a covalent bond with an electron pair as a Lewis acid. The proton donors, also known as Brnsted-Lowry acids, are the first type of acid. Proton donors in aqueous solutions generate the hydronium ion H3O+ and are known as Arrhenius acids. The Arrhenius hypothesis was expanded by Brnsted and Lowry to include non-aqueous solvents. A Brnsted or Arrhenius acid is often composed of a hydrogen atom coupled to a chemical structure that remains energetically advantageous following the loss of H+.

pH = log[H⁺]

[H⁺] = antilog(pH)

= 10² = 100

Hence, [H⁺] of the given acid is 100.

Using Avogadro’s law, the new volume of the gas is found to be 9.11L

Avogadro's law is a gas law that relates the volume of a gas to the amount of gas substance present. According to Avogadro's law, "equivalent volumes of all gases have the same number of molecules at the same temperature and pressure." Avogadro's law asserts that given the same temperature and pressure conditions, similar volumes of different gases contain an equal number of molecules.

Frequency of light that will create photoelectrons with a KE of 1.88 eV is 1.54 × [tex]10^{15}[/tex].

How to find frequency ?

The frequency of a repeating event is the number of occurrences per unit of time. It is also known as temporal frequency to distinguish it from spatial frequency and ordinary frequency to distinguish it from angular frequency.

Frequency is defined as the number of waves that pass through a fixed point in one unit of time; it is also defined as the number of cycles or vibrations that a body in periodic motion goes through in one unit of time. The number of periods or cycles per second is defined as frequency. The hertz is the SI frequency unit (Hz). A hertz is one cycle per second.

What volume of gas is generated when 58. 0 l of oxygen gas reacts at stp according to the following balanced equation? assume that the reaction goes to completion and that no starting materials remain.

Answers

The volume of gas that is CO2 generated when 58.0 L of oxygen reacts at STP is 38.67 L.

At STP, Temperature is 0°C and Pressure is 1 atm. So in this condition the one mole of gas will occupy  a volume of 22.4 L.

Since the given equation goes to completion as given in the question, the balanced chemical equation will be:

              CH₃CH₂OH  + 3O₂  ⇒ 2CO₂ + 3H₂O

From this we can calculate the mole ratio O2 to Co2 and that is 3:2.

From this we can find the volume of Co2,

Volume of CO₂ = 58  × ²/₃

Volume of CO₂ = 38.67 L

Hence the volume of gas that is CO2 generated when 58.0 L of oxygen reacts at STP is 38.67 L.

The reaction rate or rate of reaction is the rate at which a chemical reaction occurs, defined as proportional to the rise in product concentration per unit time and the reduction in reactant concentration per unit time. Chemists calculate reaction rates by initiating the reaction, evaluating the concentration of the product or reactant at various time points throughout the reaction, occasionally charting the concentration as a function of the time on a graph, and then computing the alteration in concentration per unit time. The rate of reaction may be calculated by calculating the amount of product created in a given amount of time. The time period used may be determined by the rate of the reaction.

An electron density zone might be either bonding or non-bonding. Electrons in a covalent bond between two atoms are counted as one region, whether the link is single, double, or triple (or anything in between). The amount of lone pairs on the core atom is used to count non-bonding areas.

Double and triple bonds qualify as one high electron density region. A single unpaired electron counts as one high electron density region. One can utilize any of the resonance structures for molecules or ions that have resonance structures.

A high electron density atom or group indicates that some component of the molecular structure (such as resonance or inductive effects) is transferring negative charge towards this location in the molecule.

The resulting gas pressure will be 512.08 torr.

By ideal gas law, PV = nRT

P = pressure

V = volume

n = number of mole of gas

R = gas constant

P₁= 402 torr

V₁ = 7.22 L

T₁ = 60.0°C

P₂ = ?

T₂ = 56° C

V₂ = 5.29 L

Put these values in formula, P₁V₁/ T₁ = P₂V₂/ T₂

P₂ =  P₁V₁T₂/ T₁ V₂

P₂ = 402 torr ×7.22 L ×56° C / 60.0°C ×5.29 L

A full valence shell's number of electrons less the amount of electrons involved in bonding equals the number of non-bonding electrons (which is 2 x the typical number of bonds). The amount of electrons not in bonds is equal to the number of lone pairs divided by two.

People who play video games have increased attention spans and visual recognition because they need these abilities while playing in-depth, strategy-based games. Many of these games take long periods of time to play, thus players must stay focused for longer. Developing focus can aid in learning and is an important trait for all people to have. Problem-solving, something vital for success in school and careers, is another skill that can be developed through gaming. Many games, including action and sports games, require players to solve problems quickly in order to be successful. These skills can be developed through continuous playing of video games. The multiple cognitive actions required by video games, such as those required by strategy-based games, help students develop the ability to multi-task. A recent study also suggests that those with dyslexia have improved reading and brain skills with repeated gaming experiences. With all of these benefits, there are still opponents who believe gaming is negative. Opponents believe that some games promote violence and lead to violent emotions. However, if a parent or guardian spends time discussing any violent images or situations from video games with players, these objections can be overcome. The positive benefits of perseverance and patience can become the focus of video games.3Which sentence would be the best conclusion to the essay? A. These benefits are important and overcome the negative parts of gaming. B. So, even the things people say are bad about gaming can be turned into benefits. C. Perseverance, patience, problem solving and focus are things that will help students do better. D. The lessons learned from gaming can be applied not only in school, but in everyday life as well.
