The problem you have written you almost have it solved.  Take the moles that you have calculated and multiply that by the molecular weight to get the grams.

The STP problem:
use the moles you calculated along with 1 atm for Pressure, and 273 for the temperature and plug into the PV = nRT equation.  (also use 0.0821 for R)

From there you can solve for the volume

Hope this helps!

Why is corn considered a material resource and an energy resource?
MakcuM [25]

Answer:

This is because Corn is grown on land and has important values to man .These values include as a source of food for man and animals. It is also used as raw materials for the production of certain goods such as flour etc.

It is an energy resource because fermentation of corn gives rise to ethanol fuel which is used as a source of power to run machines and other equipment.

What is the empirical formula of a compound containing carbon, hydrogen, and oxygen in the ratio 14:42:84?
Alexxandr [17]
<h3>Answer:</h3>

D. CH₃O₆

<h3>Explanation:</h3>
  • We are given the ratio of carbon, hydrogen and oxygen in a compound as 14: 42 : 84

We are supposed to determine the empirical formula of the compound;

  • We need to know what is an empirical formula;
  • An empirical formula of a compound is a formula that shows the simplest whole number ratio of elements in a compound.

In this case;

The ratio of C : H : O is 14 : 42 : 84

  • Note, this is not the simplest ratio.

But we can simplify further to get the simplest whole number ratio;

  • Therefore, 14 : 42 : 84  is equal to 1 : 3 : 6
  • Thus, the simplest whole number ratio of C : H : O in the compound is 1 : 3 : 6
  • Therefore, the empirical formula of the compound is CH₃O₆

Draw the structure of the major organic product isolated from the reaction of 3-hexyne with hydrogen (1 mol), Lindlar palladium.
ohaa [14]

Answer:

See explanation and image attached

Explanation:

When 1 mole of hydrogen is added to 3-hexyne, the addition occurs on the same face or side of the triple bond to yield cis-2-hexene in the presence of lindlar catalyst which prevents further hydrogenation. This is known as syn addition.

The syn addition is achieved because the hydrogen molecule is first adsorbed on the surface of the palladium metal and is subsequently attached to the same face of the triple bond in 3-hexyne as shown in the image attached to this answer.

Describe the main difference between the Bohr model of the atom and the Rutherford model.
atroni [7]

Answer:

The main difference between the two models was about the location of the electron in an atom.

Explanation:

<u>Rutherford described that:</u>

  • The electrons were outside of the nucleus.
  • They were equal in number to the "positiveness" of the nucleus.
  • Also, He randomly placed the negative electrons outside the nucleus.

<u>Bohr improved the Rutherford model:</u>

  • Bohr placed the electrons in distinct energy levels.
  • Electrons only exist in fixed orbitals (shells) and not anywhere in between.
  • Each shell has a fixed energy
  • Rutherford explained the nucleus of an atom, while Bohr was more into the electrons and their energy levels.
