The C-H bonds (in methane) break and so do the O-O bonds (in oxygen)
<span>The reaction is :</span>
CH4 +2O2 -> CO2 + 2H2O
Answer:
Transition states have partially formed bonds whereas intermediates have fully formed bonds.
Explanation:
According to Wikipedia, a transition state "is defined as the state corresponding to the highest potential energy along a reaction coordinate. It is easily seen as an energy maxima.
A reaction intermediate is defined as any unstable molecular entity formed as a result of interaction between reactants. This entity undergoes further chemical changes to yield the products of the chemical reaction. Intermediates occur at an energy minima in the reaction coordinate.
The bonds in a transition state are partially formed because a transition state often involves a simultaneous breaking and making of bonds while an intermediate contains fully formed chemical bonds
Answer:
Electrons get farther from the nucleus.
Explanation:
By going from the top to the bottom of a group, the atomic number increases. That would mean that:
- The number of orbitals increases, as there are more electrons.
- A higher atomic number implies an increasing number of neutrons.
- As there are more electrons, they get farther from the nucleus. The farther an electron is from the nucleus, the easier it is for the electron to be removed from the atom.
The molarity of the potassium hydroxide required to neutralize 60.0 mL of 0.0100 M H3PO4 is 0.02M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated using the following formula:
CaVa = CbVb
Where;
- Ca = concentration of acid
- Cb = concentration of base
- Va = volume of acid
- Vb = volume of base
60 × 0.0100 = 30 × Cb
0.6 = 30Cb
Cb = 0.6/30
Cb = 0.02M
Therefore, molarity of the potassium hydroxide required to neutralize 60.0 mL of 0.0100 M H3PO4 is 0.02M.

Answer:76 grams
Explanation:
Fe+H₂SO₄-->FeSO₄+H₂
For one mole of Fe we get 1 mole of feso4, therefore for 0.5 moles of Fe we get 0.5 moles of feso4.
The molar mass of feso4 is AFe+AS+4AO(A is atomic mass)
56+32+4*16=152grams/mole
Now, we need to multiply the number of moles by the molar mass to get the mass that reacts
152*0.5=76 grams
