The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules

Answers

Answer:

Due to the presence of 4 valence electrons.

Explanation:

The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules occurs because the carbon atom has four electrons in their outermost shell and the four hydrogens has one electron each which result is a total of eight electrons distributed in four bonding orbitals making the structure of tetrahedral and the bond angles between these carbon atoms is approximately 109.5 degree.

how do some plants grow and survive in the harshest environments like the dessert or under water

Answers

Answer:

Adaptation

Explanation:

Some plants grow and survive in the harshest environments like the desert or underwater by adapting to the environment. For example, some plants in the desert have thick, waxy skin to reduce loss of water and to reflect heat. They also have large, fleshy stems to store water.  Also, specific plants like cacti in the desert have spikes to protect them from animals wishing to use stored water. These adaptations help them to grow and survive in the desert.

In the ocean, plants have adapted to absorb all the water and carbon dioxide they need from the water they live in. Just as cacti have adapted to live in brutally hot deserts, ocean plants have adapted to deal with things like ocean tides and the salinity (or salt levels) of the water around them. Many ocean plants cling tightly to rocks in order to avoid being swept away by ocean tides.

Why do clouds appear and disappear?

Answers

Answer: Clouds are composed of liquid suspended water droplets in about a 100% RH environment. The three primary ways that clouds dissipate is by (1) the temperature increasing, (2) the cloud mixing with drier air, or (3) the air sinking within the cloud. Many things can increase the temperature of the cloud, like the sun, or warm air radiating off of the ground. That's why low fog and clouds tend to disappear as it warms up during the day. ... The air within the cloud descends - When the air descends, it warms.

Answers

Answer:

[tex]t=46.13days[/tex]

Explanation:

Hello there!

In this case, since the radioactive decay is considered as first-order kinetic model, whereby the remaining mass of the radioactive material involves the initial one, the rate constant and elapsed time:

[tex]A=Ao*exp(-kt)[/tex]

As we were not initially given the rate constant, we can use the half-life to calculate it as follows:

[tex]k=\frac{ln(2)}{8.040days}=0.08621days^{-1}[/tex]

Thus, we can calculated the elapsed time for the given conditions to obtain:

[tex]t=\frac{ln(0.75g/40.0g)}{-0.08621days^{-1} }\\\\t=46.13days[/tex]

What is Neutralization reaction?

Neutralization is a chemical reaction in which acid and base react to form salt and water. Hydrogen (H⁺) ions and hydroxide (OH⁻ ions) react with each other to form water.

The strong acid and strong base neutralization have a pH value of 7.

The beaker gets warm which indicates that the reaction between acid and base is an exothermic reaction releasing heat energy into the surroundings.

Therefore, The physical evidence that indicates that there has been a chemical reaction is that the beaker changes temperature and the correct option is option C.

Given that ammonia (NH3) acts as a weak base in water with a Kb of 1.8 x 10-5 at 298.0 K, calculate the pH at 298.0 K of a solution prepared by mixing 100.0 mL of a 0.050 M aqueous solution of ammonia with 20.0 mL of a 1.00 M aqueous solution of nitric acid. The final volume of the solution is 120.0 mL.

Answers

Answer:

pH = 0.903.

Explanation:

Hello there!

In this case, according to the given information about the problem, we can notice there is a reaction between nitric acid and ammonia, whereas just the H ions from the former are relevant:

[tex]NH_3(aq)+H^+(aq)\rightleftharpoons NH_4^+(aq)[/tex]

Thus, we first calculate the consumed moles of ammonia, it order to evaluate the moles after the reaction:

[tex]n_{H^+}=0.020L*1.00mol/L=0.020mol\\\\n_{NH_3}=0.100L*0.050mol=0.005mol[/tex]

It means there is a leftover of moles of hydrogen ions of 0.015mol; then, we calculate the molarity of the resulting solution as follows:

[tex][H^+]=\frac{0.015mol}{0.120L}=0.125M[/tex]

Finally, we use the formula for the calculation of the pH to obtain:

[tex]pH=-log(0.125)\\\\pH=0.903[/tex]

Which means this solution is highly acidic.

A reaction yield 6.26 g of a product what is the percent yield if the theoretical yield is 18.81 g

Answers

Explanation:

remember the equation percentage yield = actual/theoretical yield

so 6.26/18.81 X 100 gives u 33.28017012 so to 3 SF ot would be 33.3%

hope this helps:)

The statement, that describes the percent yield is 33.280 g.

What is percent yield?

The percent yield is the ratio of actual yield to theoretical yield. It is computed by dividing the experimental yield by the theoretical yield and multiplying the result by 100 percent. If the actual and theoretical yields are equal, the percent yield is one hundred percent.

To express the efficiency of a reaction, use the following formula: percent yield

= (actual yield/theoretical yield) x 100

= (6.26 g/ 18.81 g) x 100

= 33.280 g

Hence the correct answer is 33.280 g.

If 25.5g of sodium thiosulphate was dissolved in 40g of distilled water at 25°C,
I). Calculate the solubility of the solute in mol/dm^3
II). Calculate the solubility in g/dm^3

Answers

Answer:

Formula: Na2S2O3

we get solubility.

Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

Solution given:

mass of sodium thiosulphate [m1]=25.5g

mass of water [m2]=40g

at temperature [t]=25°C

we have

solubility in g/dm^3 :[tex] \frac{solute in gram}{solvent in gram} *100[/tex]

=[tex] \frac{25.5}{40}*100 [/tex]=63.75g /litre=63.75g/dm³

solubility in g/dm^3 :63.75g/dm³

Lewis acid-base concept have the following characteristics except? Option A. Have a great day .

The Lewis acid -base concepts states that acid are electron acceptors and bases are electron donors. Hence, this concept is based on the donation and acceptance of electron pair. Thus, option C is correct.

What is Lewis acid -base concept ?

According to Lewis concept of acids and bases acids are substances tends to accepts electrons and bases are electron donors. Therefore, Lewis acids are electron deficient or electrophiles.

Similarly Lewis bases are electron rich or nucleophiles. For example BF₃ is a Lewis acid and NH₃ is a Lewis base. Hence,  BF₃ can accept electron from the lone pair of nitrogen from the Lewis base NH₃. and forms the acid-base pair NH₃ - BF₃.

Lewis acid- base concepts thus states the donation and acceptance of an electron pair. Hence, option C is correct.
