F=m x a
F=force.
m=mass
a=acceleration
Data:
m=1.5 Kg
a=6 m/s²
F=1.5 kg x 6 m/s²=9 Newtons.
answer: the force will be 9 Newtons.
Answer:
I took the test it's C.The volume will increase.
Explanation:
Since the pressure went down from 2 atm to 1 atm, the volume will go up! They are inversely related.
Answer:
A. 3A + 2D → 2C + F
B. B is an intermediate
C. rate = k[A]³
D. rate = k`[D]²
Explanation:
Part A
The overall reaction is the sum of all the elementary steps:
3A→B+C
+
B+2D→C+F
<u> </u>
3A + 2D → 2C + F
Part B
A reaction intermediate is one that participates in the elementary steps, but it is not a product. Notice B is produced in the first step and consumed in the second, therefore it is an intermediate species.
Part C
The rate law is the product of the reaction constant, k, times the concentration of the reactants raised to the power of their coefficients in the balanced reaction assuming that it is the slow step in the reaction mechanism.
rate = k[A]³
Part D
Again as in part C:
rate = k [D]² ( B is not included since as we saw it is an intermediate )
Answer:
Le Chatelier's principle, also called Chatelier's principle or "The Equilibrium Law", is a principle of chemistry used to predict the effect of a change in conditions on chemical equilibria.

Answer:
5) A full s subshell is able to shield a newly filled p subshell from the nucleus, making the first electron in a p subshell easy to remove.
Explanation:
Ionization energy reffered to the measurement of the readiness of an atom to lose an electron.
While First ionization energy is defined as the energy required to remove the foremost electron that are held so loosely within the gas phase.
The number of electron in atom proportional to the size of the atom or element.when there are bigger number of electron then their would large size of atom. The ionization energy required to remove primary electron from it's outermost shell decrease as the atom size increase.
Repulsion of Electron to electron takes place when there is repelance between the electrons within the same sub-level. There is shielding effect when inner electrons shield the outer electrons from been pulled off the nuclear charge.
Therefore, a full ss subshell is ready to shield a newly filled p subshell from the nucleus, making the primary electron in an exceedingly p subshell easy to get rid of.
because there is high shielding effect byan s-subshell compare to the p,d, and f sub-shell order, and it is easy to remove new electron within p-sublevel because it is held loosely
