Answer:

frequency increases as wavelength decrease.

Explanation:

frequency = velocity/wavelength

Answer:

Frequncy increases, wavelength decreases

Explanation:

A wave can be defined as the repetitive pattern of a travelling energy. Waves can also be defined as a disturbance from equilibrium (or rest) of a medium which oscillates along a stable region. Examples of waves include: seismic waves, gravitational waves, shock waves, heat waves, sound waves etc

In a standing wave (ie at different points of the wave, amplitude is constant), its properties are:

Amplitude which is the the distance of the disturbance from equilibrium. It can also be defined as the distance between the highest point of the wave(peak or crest) to the lowest point (trough).

Wavelength(lambda) is the distance between one peak to the next peak or one trough to another trough parallel to the direction of propagation.

Frequency, f is the number of times a wave passes a particular point per unit time.

Wave velocity is the speed at which disturbance moves. It can given as an equation:

V = f*(lambda)

It can also be written as:

f = V/(lambda)

From the relationship above,

We can see that an increase in frequency of the wave would lead to a decrease in its wavelength and vice versa.

How many moles of FeCI3 are present in 345.0 g FeCI3
Sphinxa [80]

Answer:

\boxed {\boxed {\sf About \ 2.127 \ moles \ of \ FeCl_3}}

Explanation:

To convert from moles to grams, the molar mass must be used.

1. Find Molar Mass

The compound is iron (III) chloride: FeCl₃

First, find the molar masses of the individual elements in the compound: iron (Fe) and chlorine (Cl).

  • Fe:  55.84 g/mol
  • Cl:  35.45 g/mol

There are 3 atoms of chlorine, denoted by the subscript after Cl. Multiply the molar mass of chlorine by 3 and add iron's molar mass.

  • FeCl₃: 3(35.45 g/mol)+(55.84 g/mol)=162.19 g/mol

This number tells us the grams of FeCl₃ in 1 mole.

2. Calculate Moles

Use the number as a ratio.

\frac{162.19 \ g \ FeCl_3}{1 \ mol \ FeCl_3}

Multiply by the given number of grams, 345.0.

345.0 \ g \ FeCl_3 *\frac{162.19 \ g \ FeCl_3}{1 \ mol \ FeCl_3}

Flip the fraction so the grams of FeCl₃ will cancel.

345.0 \ g \ FeCl_3 *\frac{1 \ mol \ FeCl_3}{162.19 \ g \ FeCl_3}

345.0 *\frac{1 \ mol \ FeCl_3}{162.19 }

\frac{345.0 \ mol \ FeCl_3}{162.19 }

Divide.

2.12713484 \ mol \ FeCl_3

3. Round

The original measurement of grams, 345.0, has 4 significant figures. We must round our answer to 4 sig figs.

For the answer we calculated, that is the thousandth place.

The 1 in the ten thousandth place tells us to leave the 7 in the thousandth place.

\approx 2.127 \ mol \ FeCl_3

There are about <u>2.127 mole</u>s of iron (III) chloride in 345.0 grams.

Uranium-235 has a half-life of 713 million years. Would uranium-235 or carbon-14 be more useful for dating a fossil from Precamb
9966 [12]
Answer: Uranium-235.

Radioactive isotopes are used to determine the age of antique objects, including fossils.

The half-life time of the radioactive elements is what permits the process of dating.

The half-life of C-14 is too short to be useful to date too old objects.

Precambrian time is the most antique era. C-14 hal-life is about 5730 years and Precambrian time is millions or billions of years ago. Given that the hal-life of U-235 is 704 million years it is appropiate to date the fossils from the Precambrian era.
