Answers

Answer 1

Answer:

Answer: -

Many drugs are sold as their hydrochloric salts (RNH₃⁺Cl⁻), formed by reaction of an amine (RNH₂) with HCl.

It is done because amines are generally liquids. But their hydrochloric salts are solid. A solid drug is always more preferable for drug companies as their handling and packaging are easier.

Acebutolol consists of one amide functionality as well as a secondary amine functionality.

When HCl is added, the lone pairs of the nitrogen of the secondary amine attacks it, leading to the formation of it's hydrochloric salts.

In living organisms, C-14 atoms disintegrate at a rate of 15.3 atoms per minute per gram of carbon. A charcoal sample from an archaeological site has a C-14 disintegration rate of 9.16 atoms per minute per gram of carbon. Estimate the age of this sample in years. The half-life of C-14 is 5730 years. (enter only the number of years in standard notation, not the unit years)

Answers

Rate of disintegration is defined as the time required by a sample or substance at which half of the radioactive substance disintegrates. It depends on the nature of disintegration and amount of substance.

The age of the sample is approximately 4241.17 years.

Given that:

C-14 atoms disintegration rates = 15.3 atom/ min-g

Rate of disintegration of the sample = 9.16 atom/ min-g

The digit proportion of carbon-14 is = $(9.16)/(15.3)$ = 0.5987

Now, also the half-life of carbon-14 is 5730 years.

Such that:

$(1)/(2)^n = \text A$

$(1)/(2) = 0.5987$

Taking log:

n log 2 = -log 0.5987

Thus, n = $(0.227)/(0.3010)$

n = 0.740

The age of the sample can be given by:

Age = n x half-life

Age = 0.740 x 5730

Age = 4241.17 years.

Therefore, the age of the substance is 4241.17 years.

Answer:

The answer is "4,241 .17 years"

Explanation:

The disintegration rate, which shows in C-14 atoms = $15.3 (atoms)/(min-g)$

Rate of sample disintegration = $9.16 \frac{atoms} {min-gram}$

The digit proportion of C-14 can be determined that is included in the sample $= \frac {9.16}{15.3} \n\n = 0.5987$

5730 years from half-life.

The number with half-lives (n) which are repelled must be determined:

$((1)/(2))^n= A\n\nA= fraction of C-14, which is remaining \n\n((1)/(2))^n= 0.5987 \n\n n \log 2 = - \log 0.5987\n\n$

$\therefore \n\n \Rightarrow n= (0.227)/(0.3010) \n\n = 0.740\n$

So, the age of the sample is given by = $n *\ half-life$

$= 0.740 * 5730 \ years \n\n=4241.17 \ years\n\n$

Is clear water pumped from a deep aquifer a pure substance?

Answers

The substance which has definite composition with definite physical and chemical properties is said to be pure substance. These substances are not separated by the different physical techniques such as filtration, distillation, evaporation etc.

The clear water pumped from a deep aquifer is a pure substance because water is a pure compound which consist of constant single type of atoms or group of atoms and water has specific value of boiling and melting point. Water is also not separated into units or constituents by physical technique.

Hence, clear water pumped from a deep aquifer is a pure substance.

Answer:

Yes

Explanation:

As pure substances are substances that are formed directly by elements and water is directly formed by the union of two elements which is Oxygen and hydrogen, H2O is the formula and that is a pure substance as it is conformed mainly by only these two elements, so the question would be Yes, clear water pumped from a deep aquifer is a pure substance.

b. Is colorless in the presence of water
c. Does not exist as a hydrate
d. Forms different hydrates which have different colors

Answers

Answer:Forms different hydrates which have different colors

Explanation:

CoCl2 in its anhydrous form is blue in colour. This anhydrous compound could absorb moisture, first forming the purple dihydrate and absorbs more water molecules to form the hexahydrate. Hence various hydrates of cobalt II chloride have different colours as stated above. Equations of reaction for the formation of the two hydrates are attached.

A substance with a high vapor pressure at normal temperatures is often referred to as volatile. As the temperature of a liquid increases, the kinetic energy of its molecules also increases and as the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.

Answers

As the temperature of a liquid or stable will increase its vapor strain additionally will increase. Conversely, vapor strain decreases because the temperature decreases.
