what is the percentage by mass of hydrogen (H) in lithium hydroxide (LiOH)

Answer:

Answer: Hyperoxic alligators show significantly lower breathing rates than their siblings in normoxic and hypoxic groups. Conversely, each breath supports greater oxygen consumption in hyperoxic animals than in other groups. Statistical significance between groups was calculated by ANOVA with post hoc Tukey-Kramer

The explanation regarding the less atmospheric oxygen levels impacted the alligators growth should be because of Hyperbolic alligators.

There should be less breathing rate and the consumption of the oxygen should be high per breath.

The compensatory cardiopulmonary remodeling, the growth of the hypnotic alligators should be constrained by the less temperature with respect to the supply of the oxygen that should limited the food utilization capacity.

Answer:

0.854

Explanation:

The equation of its dissolution in water is: AgNO3 → Ag + (aq)  +  NO3- (aq)

and     AgNO3 →   Ag + (aq)  +  NO3- (aq)

         1 mol          1mol                1mol

            ?  --------   0.854mo

so for finding the value, it is sufficients to complute 1 x 0.854 mol =0.854 mol

so,  0.854 mol is required for the reaction to form 0.854 mol of Ag

Since the exact values of the service times are not provided, it is not possible to calculate the 3-sigma control limits. Therefore, the correct answer is "None of the other options."

The 3-sigma control limits are used in statistical process control to determine the acceptable range of variation in a process. To calculate the 3-sigma control limits, we need to first find the mean and standard deviation of the service times for the 20 randomly selected customers.

Step 1: Find the mean (average) of the service times.
Add up all the service times and divide by the total number of customers (20).

Step 2: Find the standard deviation of the service times.
Calculate the difference between each service time and the mean, square each difference, sum up all the squared differences, divide by the total number of customers (20), and then take the square root of the result.

Step 3: Calculate the 3-sigma control limits.
Multiply the standard deviation by 3 and add/subtract the result to/from the mean. This will give you the upper and lower control limits.

Since the exact values of the service times are not provided, it is not possible to calculate the 3-sigma control limits. Therefore, the correct answer is "None of the other options."

If one chamber had a lower in-flow of air than the other chambers, It would bias the results toward less photosynthesis. The correct answer is C.

If one chamber received less air from the outside than the other chambers the amount of CO₂ entering a chamber would be reduced if it had a lower air inflow than the other chambers, which would result in lower CO₂ exit levels in that chamber.

This can bias the information gathered from that chamber and result in erroneous measurements and deductions. Making ensuring that the air entering each chamber is flowing equally is crucial for accurate measurements.

It is crucial to make sure that the airflow into each chamber is uniform if you want to prevent such mistakes. This can be done by using a constant flow rate throughout all chambers or by measuring and controlling the airflow into each chamber with flow meters.

Researchers can collect accurate and reliable data by using controlled and consistent circumstances, which is essential for valid scientific conclusions.

Answer:

A= 2.3g

B= 1.2L

Explanation:

a) Find the mass of the reacted metal

2Na    +     Cl2     →    2NaCl

46               71                 117

X                                   5.85

From the chemical equation

117/5.85 = 46/x

X= (46x5.85)/117

 = 2.3g

So, the mass of the reacted metal is 2.3g

b) Find the volume of the reacted gas at STP

at STP: 71g of CL2 has 22.4l

              Y  of Cl2 has V

V= (Y x 22.4L) / 71                   where y=?

From the chemical equation

117 / 5.85 = 71 / Y

Y= (71x5.85) / 117

  = 3.55

V= (3.55x22.4) / 71

 = 1.12L

So, the volume of the reacted gas at STP is 1.12L

The reactivity of halogens in free radical halogenation follows the order: fluorine > chlorine > bromine > iodine. This is due to the decreasing bond dissociation energy (BDE) of the halogen-halogen bond in this order.

Therefore, in the free radical halogenation of ethane, fluorine would be the most reactive halogen and undergo the reaction most rapidly. Chlorine would be less reactive than fluorine but more reactive than bromine and iodine.

Iodine and bromine are not as reactive as fluorine and chlorine due to their large size and lower electronegativity, which results in a weaker halogen-halogen bond. As a result, the reaction between ethane and iodine or bromine would be slower than that with fluorine or chlorine.

Finally, pyridine is not a halogen and is not expected to undergo free radical halogenation with ethane.

Answer:

weak bonds require less energy to form bonds than strong bonds

Answer:

because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation

Explaination:

the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.

Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.

It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.

Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.

Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.

Oxidation state is defined as the total number of electrons that have been deleted or added to an element.

It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.

To determine the number of atoms in 0.85 moles of Sodium (Na), we need to use Avogadro's number, which is 6.022 x 10^23 particles per mole.

Number of atoms = moles x Avogadro's number

Number of atoms = 0.85 mol x 6.022 x 10^23 particles/mol

Number of atoms = 5.12 x 10^23 atoms

Therefore, there are approximately 5.12 x 10^23 atoms in 0.85 moles of Sodium (Na).

Atoms will combine with each in order to become more chemically stable. Compounds are formed between two atoms that have incomplete outer energy levels. The two types of compounds that can be formed between atoms are ionic and covalent. Ionic compounds are formed between two oppositely charged atoms. ionic compounds contain a metal ion and a non - metal ion:

Metals will lose electrons to form positive ions and nonmetals will gain elections to form negative ions. These oppositely charge ions are very attracted to each other and forms very strong bonds as a result.

Ionic compounds are characterized by crystalline structure.

Earth inner core is responsible for creating its magnetic field.

Like a result of radioactive heating and chemical differentiation, the Earth's outer core is experiencing turbulent convection. This initiates a process similar to that of a naturally occurring electrical generator, in which advective kinetic energy is converted to electricity and magnetic energy. In essence, the motion of a electrically conducting iron inside the presence of the Earth's magnetic field causes electric currents to flow. Because the electric currents start generating their own magnetic field, the process is self-sustaining as long as there is a energy source sufficient to maintain convection.

The Earth is made up of layers with varying chemical compositions and physical properties. The Earth's crust is permanently magnetized, and the Earth's core generates its very own magnetic field, which sustains the majority of the field we measure at the surface. As a result, we could claim that the Earth is really a "magnet."

A solvent is that component of a solution that completely dissolves the solute in it to form a homogenous mixture “solution”. In addition to being a liquid, a supercritical fluid, a solid, or a gas can also be a solvent.

The solution is a homogenous mixture composed of Solvent (larger in concentration) and Solute (smaller in concentration).

A homogenous mixture of two or more than two components is termed as a solution. The material with the highest concentration is referred to as the solvent, while the substance with the lowest concentration is referred to as a solute.
