<span>A chemical equation is balanced by changing or adding C. numbers in front of molecules, which are called coefficients.
For example:
O2 + 2 H2 ---> 2 H2O (number 2 is added to both sides in order to balance the equation)</span>
Answer:
Explanation:
A bronsted lowry acid just means that it donates a proton.
An arrhenius acid dissolves in water to donate a proton
the only difference is that an arrhenius acid must dissolve in water but it still donates a proton so it is considered a bronsted lowry acid
Answer:
% of n-propyl chloride = 43.48 %
Explanation:
There are 2 secondary hydrogens and 6 primary hydrogens
The rate of abstraction of seondary hydrogen = 3.9 X rate of abstraction of primary hydrogen
probability of formation of isopropyl chloride = 3.9 X 1 (relative rate X relative number of secondary hydrogens)
Probability of formation of n-propyl chloride = 1 X 3 (relative rate X relative number of primary hydrogens)
Total probability = 3.9
% of n-propyl chloride = 3 X 100 / 6.9 = 43.48 %
A. Distillation. If the mixtures have different boiling points, the liquid with the lower boiling point will distill off first, followed by the other one.
“B. Filtration” is <em>incorrect</em>. Both liquids will pass through the filter paper.
“C. Sedimentation” is <em>incorrect </em>because it works only for a solid suspended in a liquid.
“D. Evaporation” is <em>incorrect</em>. Both liquids will pass into the atmosphere never to be seen again.
Exothermic releases energy(heat) from the system to the surrounding
endothermic takes energy (heat) from the surrounding to the system
