Answer:

hope this helps

Explanation:

Photosynthesis

Photosynthesis

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phos, "light", and sunthesis "putting together". In most cases, oxygen is also released as a waste product. Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Calculate the volume of oxygen at NTP obtained by decomposing 12.26g of KCLO3(at wt. K=39.1, Cl=35.5 and O = 16)​
Anuta_ua [19.1K]

Answer: 3.61 L

Explanation:

To calculate the moles, we use the equation:

moles=\frac{\text {given mass}}{\text {Molar mass}}

moles=\frac{12.26g}{122.6g/mol}=0.1moles

2KClO_3\rightarrow 2KCl+3O_2

2 moles of  KClO_3  produce = 3 moles of  O_2

0.1 moles of  KClO_3 produce = \frac{3}{2}\times 0.1=0.15 moles of    O_2

According to the ideal gas equation:'

PV=nRT

P = Pressure of the gas = 1 atm (NTP)

V= Volume of the gas = ?

T= Temperature of the gas = 20°C = (20+273) K = 293 K    (NTP)

R=  Value of gas constant in in kilopascals = 0.0821 Latm/K mol

1\times V=0.15\times 0.0821\times 293

V=3.61L

Thus volume of oxygen at NTP obtained by decomposing 12.26 g of  KClO_3 is 3.61 L

Describe the buffer capacity of the acetic acid buffer solution in relation to the addition of both concentrated and dilute acid
AysviL [449]

Answer:

The answer is in the explanation

Explanation:

Acetic acid, CH₃COOH, is a weak acid that will produce a buffer when its conjugate base, CH₃COO⁻, acetate ion, is added to the solution.

<em>That is because a buffer is the mixture of a weak acid and its conjugate base or vice versa.</em>

When an acid (HX) is added to the solution, the acetate ion will react producing acetic acid, thus:

CH₃COO⁻ + HX → CH₃COOH + X⁻

For this reason, the pH doesn't change abruptly because H⁺ ions are not produced.

Now, if a  base (BOH) is added to the buffer, CH₃COOH will react producing acetate ion and water, thus:

CH₃COOH + BOH → CH₃COO⁻ + H₂O + B⁺.

In the same way, there are not produced free OH⁻ and the pH doesn't change significantly.
