djverab [1.8K]3 years ago
7 0

Answer:

The answer is explained below.

Explanation:

In a few and easy words, the term dimensional analysis can be explained as a way chemists and other scientists convert units of measurement. For example, it is possible to convert grams into another unit of weight, such as pounds or kilograms because we know how many of them are contained in each unit (454 and 1000.)

Answer:

Dimensional Analysis is a way chemists and other scientists convert units of measurement . We can convert any unit to another unit of the same dimension . This means we can convert some number of seconds into another unit of time , such as minutes , because we know that there are always  60 seconds in one minute . or we can convert some amount of mass from grams to kilograms knowing that there are always 1000 grams in one kilogram . or we can convert lengths, say, from kilometers to miles , although <u><em>metric units</em></u> are most frequently used in chemistry .  with a known conversion factor , it is sometimes , possible to convert to a new dimension , for instance , 1 kilogram of pure water is equal to 1 liter . using that knowledge , you could convert a volume of water to a mass of water , or vice versa .

A certain kind of light has a wavelength of 4.6 micrometers what is the frequency of this light and gigahertz? Use c= 2.998 × 10
Leno4ka [110]

Answer:

6.52×10⁴ GHz

Explanation:

From the question given above, the following data were obtained:

Wavelength (λ) = 4.6 μm

Velocity of light (v) = 2.998×10⁸ m/s

Frequency (f) =?

Next we shall convert 4.6 μm to metre (m). This can be obtained as follow:

1 μm = 1×10¯⁶ m

Therefore,

4.6 μm = 4.6 μm × 1×10¯⁶ m / 1 μm

4.6 μm = 4.6×10¯⁶ m

Next, we shall determine frequency of the light. This can be obtained as follow:

Wavelength (λ) = 4.6×10¯⁶ m

Velocity of light (v) = 2.998×10⁸ m/s

Frequency (f) =?

v = λf

2.998×10⁸ = 4.6×10¯⁶ × f

Divide both side by 4.6×10¯⁶

f = 2.998×10⁸ / 4.6×10¯⁶

f = 6.52×10¹³ Hz

Finally, we shall convert 6.52×10¹³ Hz to gigahertz. This can be obtained as follow:

1 Hz = 1×10¯⁹ GHz

Therefore,

6.52×10¹³ Hz = 6.52×10¹³ Hz × 1×10¯⁹ GHz / 1Hz

6.52×10¹³ Hz = 6.52×10⁴ GHz

Thus, the frequency of the light is 6.52×10⁴ GHz

If excess sodium is added to 0.10 L of 1.00 M hydrochloric acid solution, how many moles of NaCl is formed?
Ksenya-84 [330]

Answer:

=> 0.10 moles

Explanation:

The question is asking us to find the moles of NaCl cid formed.

We have been provided with;

0.10 L of 1.0 M NaOH.

We know that mole ratio of the reaction is 1:1 and also the molarity of a solution is contained in 1 L or 1000 mL or 1000 cm³.

This means that;

1.0 M is contained in 1.0 L.

X mol is contained in 0.10 L

x \: mol \:  =  \frac{0.1 \times 1.0}{1.0}  \\  = 0.10 \: mol

= 0.10 moles of NaCl formed

Freon-12, CF2Cl2, which has been widely used in air conditioning systems, is considered a threat to the ozone layer in the strat
Vilka [71]

Answer:

The root mean squared velocity for CF2Cl2 is  v_{rms}= 207.06 m/s

Explanation:

From the question we are told that

         The temperature is T = -65 ^oC = -65+273 = 208K

Root Mean Square velocity is mathematically represented as

      v _{rms} = \sqrt{\frac{3RT}{MW} }

 Where  T is the temperature

              MW is the molecular weight of gas

              R is the gas constant with a value of  R = 8.314 JK^{-1} mol^{-1}

For  CF2Cl2 its molecular weight is  0.121 kg/mol

     Substituting values

  v_{rms} = \sqrt{\frac{3 * 8.314 *208}{0.121} }

          v_{rms}= 207.06 m/s
