 A geologist will ask an analytical chemist to help identify the minerals in a rock because an analytical chemist studies the composition of matter and, therefore, can identify the minerals.

The analytical chemist does this by determining the crystal structure as a matter of routine using X-ray and electron diffraction techniques.

The half-life of C-14 is 5470 years. If a particular archaeological sample has one-quarter of its original radioactivity remaini
Gennadij [26K]

Answer:

When there remains one-quarter of the sample, the age of the sample is 10940 years

Explanation:

<u>Step 1:</u> Data given

The half-life of C-14 is 5470 years.

The half- life time is the time required for a quantity to reduce to half of its initial value.

This means after 5470 years there remains half of the C-14 sample.

To remain a quarter of the sample, another cycle of 5470 years is required.

This means 2 half-lives should have passed to remain a quarter of the sample.

<u>Step 2</u>: Calculate it's age

t/(t/1/2) = 2

⇒ with t = the age (or time) of the sample

⇒ with t(1/2) = the half-life time of the sample = 5470 years

⇒ with 2 = the number of halvf- lives passed

t/5470 = 2

t = 2*5470 = 10940 years

When there remains one-quarter of the sample, the age of the sample is 10940 years

iogann1982 [59]

Answer:

the ratio would be 1:2:1

Explanation:

since it is C6 H12 O6

12 is double of 6 so it would be 2

and 6 is considered 1

If water (p=998 kg/m3, u = 10-3 Pa.s) flows through a 50 m Pa.s) determine the velocity of carbon tetrac me the velocity of carb
babymother [125]

Explanation:

As it is given that both have same dynamic characteristics.

Therefore,      Re_{water} = Re_{CCl_{4}}

    \frac{\rho_{water} \times \nu_{water} \times D_{water}}{\mu_{water}} =  \frac{\rho_{CCl_{4}} \times \nu_{CCl_{4}} \times D_{CCl_{4}}}{\mu_{CCl_{4}}}

Hence, putting the given values into the above formula as follows.

   \frac{998 kg/m^{3} \times 2 m/s \times 50 mm}{10^{-3}Pa.s} =  \frac{1590 kg/m^{3}} \times \nu_{CCl_{4}} \times 60 mm}{0.958 \times 10^{-3}}    

                   \nu_{CCl_{4}} = 1.002 m/s

Thus, we can conclude that the velocity of carbon tetrachloride in the given conditions is 1.002 m/s.

You have been given an orange liquid and told to describe its properties.
chubhunter [2.5K]

Answer:

The correct answer would be - observing with the help of five senses.

Explanation:

To find and describe the physical properties of the given substance or the solution or liquid students can observe using their five senses. By looking at the liquid one can find its state and color, by smelling students can find the odor of the sample, by touching it one can observe and describe the texture.

Fluidity can also be measure by the touch if the solution is viscous or free-floating. By using a thermometer and using a graduated cylinder one can find the temperature at room temperature and the weight of substance respectively.
