Which information must be known about a compound to find the molecular formula from the empirical formula?

Answers

Answer:

Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds.

Answers

More positive ions shows acidic whereas more negative ions indicates basic solution.

Which charge show acidic solution?

That side which has more positive charges is considered as acidic solution while on the other hand, that region where negative charges are present in large number as compared to positive charges is considered as basic or alkaline solution.

So we can conclude that more positive ions shows acidic whereas more negative ions indicates basic solution.

Alkaline batteries are non-rechargeable.
Why do alkaline batteries eventually stop working?

Answers

Answer:

Alkaline batteries stop working when all of the manganese dioxide has been converted.

Explanation: Hope it helps you :)))

Have a good day

Alkaline batteries eventually stop working because the chemicals inside them react and eventually use up all their energy.

The chemicals in an alkaline battery are zinc and manganese dioxide, which are separated by a separator. When the battery is used, zinc and manganese dioxide react to produce electricity.

The reaction between zinc and manganese dioxide is a one-way reaction, meaning that it cannot be reversed. This means that once the chemicals in the battery are used up, the battery will no longer produce electricity.

The rate at which an alkaline battery loses its charge depends on a number of factors, including the temperature, the amount of current being drawn from the battery, and the age of the battery.

In general, alkaline batteries will last longer in cool temperatures and when they are not being used heavily.

Explain how each property affects the energy in a wave:
Amplitude:
Wave speed:
Wavelength:
Frequency:

Answers

Answer:Amplitude:the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.Wave speed:Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known.Wavelength:Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters (m), centimeters (cm) or millimeters (mm).Frequency:frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

Which of these is a challenge related to nuclear fusion reactions?
A. Waste products have a longer half-life.
B. It is technically challenging to create these reactions safely and
efficiently.
C. The fuel for nuclear fusion is less available than uranium-235.
D. There is less of a chance of runaway chain reactions.

Answers

Answer:B

Explanation:got it right

The statement, "It is technically challenging to create nuclear fusion reactions safely and efficiently", is related to nuclear fusion reaction. Thus, Option B is correct.

This is due to the need to reach and maintain the extreme temperatures and pressures required for the reaction to occur and to confine and control the plasma in which the reaction takes place.

Nuclear fusion is a promising source of energy that has the potential to provide abundant, clean & sustainable power. However achieving nuclear fusion requires overcoming several challenges including the technical difficulties of creating and controlling the extreme conditions required for the reaction to occur.

Fusion reactions can produce high-energy neutrons that can damage the materials used to contain the reaction and require special handling and disposal. While progress has been made in developing fusion technologies, there is still much work to be done to make fusion a viable source of energy for the future.
