The correct answer is "halogens." Fluorine, chlorine, bromine, and iodine are part of a family called halogens. In the periodic table, it is the column that is beside, left of the noble gases. <span>The name 'halogen' means 'salt-producing'.</span>
Answer:
11.5moles of oxygen gas
Explanation:
The reaction equation is shown below;
C₂H₆O + 3O₂ → 2CO₂ + 3H₂O
We were given 11.5moles of H₂O produced;
Since the equation is balanced;
3 mole of oxygen gas was used to produce 3 mole of water
11.5 moles of water will be produced = 11.5moles of oxygen gas
Answer:
0.20 moles of Pb(CH3COO)4
Explanation:
89g Pb(CH3COO)4 x 1 mol Pb(CH3COO)4 / 443.376 g Pb(CH3COO)4
= 0.20 moles of Pb(CH3COO)4
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
