Answer:
shift to restore equilibrium
Explanation:
Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.
Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.
Equilibrium is the state of a reversible reaction when:
• two opposing reactions occur at the same rate;
• the concentrations of reactants and products are constant

Name the following cycloalkane:
CH2CH2CH2CH3
A. butylcyclohexane
B. butylcyclopentane
C. propylcyclohexane
Answers
Answer:
The answer for this question is A. butylcyclohexane
Explanation:
Choose letter A
You welcome have a nice day.
Name of the given compound is butyl cyclohexane.
What are cyclo alkanes?Cyclo alkanes are those organic compounds in which alkanes are present in the cyclic form.
In the nomenclature of cyclo alkane, name of the substitute is put before the name of the main ring. In the given structure number of carbons in ring is 6 so that given cycloalkane is cyclohexane and butyl group is attached as substitute. So name of the given compound is butyl cyclohexane.
Butyl cyclopentane is wrong because 6 carbons are present in ring.Propylcyclohexane is also wrong because 4 carbons are attached in the ring.Hence name of the compound is butyl cyclohexane.

Question 16
A hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
What happens according to Newton’s first law of motion?
A) The puck does not lose any speed because ice is a very slippery surface.
B) The puck gradually slows down because mass makes objects slow down.
C) The puck gradually slows down because friction would be acting on it.
D) The puck does not lose any speed because once an object starts moving, the force of friction would no longer apply to it.
Answers
Answer:
C) The puck gradually slows down because friction would be acting on it.
Explanation:
It would be C because the puck would be scraping the ice and when it's scraping it slowly losses its speed because the ground is pushing it lightly

Fe2O3 (s) + 2 Al (s) ---> 3 Fe (l) + Al2O3 (s) Based on the thermite reaction, how much aluminum oxide (Al2O3) is formed from 8.0 grams of aluminum (Al)?
Answers
Answer:
15.3 g
Explanation:
Fe₂O₃ (s) + 2Al (s) → 3Fe (l) + Al₂O₃ (s)First we convert 8.0 grams of aluminum into moles, using its molar mass:
8.0 g Al ÷ 27 g/mol = 0.30 mol AlThen we convert 0.30 moles of aluminum into moles of aluminum oxide, using the stoichiometric coefficients:
0.30 mol Al * [tex]\frac{1molAl_2O_3}{2molAl}[/tex] = 0.15 mol Al₂O₃Finally we convert 0.15 moles of Al₂O₃ into grams, using its molar mass:
0.15 mol Al₂O₃ * 102 g/mol = 15.3 g Al₂O₃Which element would you predict to have the highest first ionization energy? Why?
a) neon or carbon
b) fluorine or francium
c) beryllium or strontium
d) iodine or fluorine

Answers
Answer:
0.04506 mol
Explanation:
For this problem, you need to convert grams to moles. To do this, you need the molar mass, which is given. Divide the mass by the molar mass to find the moles you have.
(5.001 g)/(110.98 g/mol) = 0.04506 mol
