Answer:

6 elements which are  carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus

Explanation:

Living organisms are made up of various unit of giant organic molecules that have been produced through life processes.

The bulk of elements that makes up living organisms are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus.

Carbon is almost present everywhere in living organisms. It's unique ability to form a key component lies on its bond formation capabilities. Carbon is found in nearly all organic molecules like carbohydrates, proteins, fats and oils, e.t.c

Hydrogen like carbon is key to life. It is light and making it form different bond types with carbon. It is one of the atoms that makes up water.

Nitrogen is usually found in proteins. They are unique elements that life cannot do without.

Oxygen is useful in respiration processes and it is the bedrock through which energy is released from glucose.

Sulfur is key to life.

Phosphorus in Adenosine Diphosphate is a good store of energy.

How many moles of CO2 are produced when 3.3 moles of C2H2 react
xxTIMURxx [149]
<span>To solve this exercise you need to know that to create CO₂ with C₂H₂ is necessary to have oxygen. So, the following balanced equation represents the reaction:
2C₂H₂(g) + 5O₂(g) → 4CO₂(g) + 2H₂O(g)

Notice that 2 moles of C₂H₂ form 4 moles of </span><span>CO₂, so if </span>3.3 moles of C₂H₂ react, how many moles of CO2 would be produced?
2 moles <span>of C₂H₂ -------</span>4 moles of <span>CO₂
3.3 </span><span>moles <span>of C₂H₂--------x moles of CO₂
x=6.6  </span></span><span>moles of CO₂ produced.</span>

What mass of silver chloride can be produced from 1.27L of a 0.156M solution of silver nitrate?
pentagon [3]

Answer:

m AgCl = 28.395 g

Explanation:

  • AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

∴ [AgNO3] = 0.156 mol/L

∴ V = 1.27L

⇒ mol AgNO3 = 0.156 mol/L * 1.27 L = 0.19812 mol AgNO3

mass AgCL:

⇒ m AgCl = 0.19812 mol AgNO3 * mol AgCl/molAgNO3 * 143.32gAgCl/molAgCl

⇒ m AgCl = 28.395 g

Determine the frequency of radiation whose wavelength is 7.67 x 10^-7 cm. Then, determine the amount of energy in the radiation.
dimulka [17.4K]

Answer:

They frequency = 3.9 * 10^16 Hz

The amount of energy E = 2.58 *10^-17 J

Explanation:

Step 1: Data given

wavelength is 7.67 * 10^-7 cm

Step 2: Calculate the frequency

f = c / λ

⇒ with  λ = the wavelength in nm = 7.67 nm

⇒ with c = the speed of light  = 3.00 * 10^8 m/s

⇒ f = the frequency = TO BE DETERMINED

f = (3.00 * 10^8 m/s) / 7.67 * 10^-9 m

f = 3.9 * 10 ^16 /s = 3.9 * 10^16 Hz

They frequency is 3.9 * 10^16 Hz

Step 3: Calculate the amount of energy

E  =  h *f

⇒ with E = the amount of energy (in joule)

⇒ h = Planck's constant =  6.626  *10^-34 J*s

⇒ with f = the frequency

E =  6.626  *10^-34 J*s * 3.9 * 10^16 Hz

E = 2.58 *10^-17 J
