If you have 600 g of c6h12o6 then how many grams of oxygen are there

1 answer:

7 0

so your ratio for the equation is 1 glucose + 6 oxygen = 6 carbon dioxide + 6 water

those ratios will all be in moles, and will all be based on the number of moles of your limiting reagent. We assume that you have unlimited oxygen, so glucose must be limiting. The molar mass for glucose is 180 grams (you can get more accurate if you need, this is just the number I am using).

100 g / 180 g/mol = 0.556 moles of glucose.
since we will need six times the moles of glucose in oxygen...
6 x .556 = 3.33 moles of O2
multiply by the molar mass of O2 for the mass of oxygen needed...
3.33 x 32 = 106.67 grams of O2
since you are forming six times the moles of glucose in CO2 and H2O, you are forming 3.33 moles of each of these compounds as well.

Positron emission = emission of a positron and a neutrino when a proton is convert into a neutron. The total number of particles in the nucleus doesn't change, -1 proton +1 neutron

It's a spontaneous reaction for some nucleus.

eg:

Positron = e+

Neutrino=ve

O-15 --> N-15 + e+ +ve

Electron capture= A nucleus absorb an electron while a proton is convert in a neutron and emit a neutrino. The total number of particles in the nucleus doesn't change, -1 proton +1 neutron

eg:

Al-26 +e- --> Mg-26 + ve

Electron capture and positron emission are two mechanisms to explain the decay of some unstable isotopes. Electron capture is usually observed when the energy difference between the initial and final state is low. Mainly because of the larger amount of kinetic energy need for the expulsion two particles with the positron emission mechanism.

The reaction of pyrrole with bromine forms predominantly __________. View Available Hint(s) The reaction of pyrrole with bromine

xenn [34]

Answer:

a) 2-bromopyrrole

Explanation:

Our options for this questions are:

a) 2-bromopyrrole

b) 2,3-dibromopyrrole

c) N-bromopyrrole

d) 3-bromopyrrole

To understand how the reaction works we have to start with the resonance structures. (Figure 1), on these structures, we will obtain a negative charge on carbon 2 in the pyrrole ring, therefore on this carbon we can generate an attack to an electrophile.

The second step is to check how the mechanism take place. An electrophile is generated by the $Br_2$ and $FeBr_3$ . This electrophile can be attacked by the negative charge on carbon 2 producing the 2-bromopyrrole. (See figure 2).
