Which explains the change in ionization energy that occurs between removing the first and second electrons from an atom?
Answer:
"The strength of ionization decreases as the proportion including its protons to the excited electrons" is the right solution.
Explanation:
The ionizing procedure, the creation of ions through manipulating individual atoms or revolutionaries, or through decreasing or increasing charged particles in something other than gas by intense electrical fields.It should be the total removal of someone with an electron through an atomic nucleus rather than from molecules. The corresponding molecule has denominated an ion.This question seems incomplete. I believe the answer choices are as followed:
O The ionization energy decreases because the ratio of the protons to electrons increases.
O The ionization energy increases because the ratio of the protons to electrons increases.
O The ionization energy decreases because the ratio of the protons to electrons decreases.
O The ionization energy increases because the ratio of the protons to electrons decreases.
The answer to this is The ionization energy increases because the ratio of the protons to electrons increases. (2nd option).

Balance the chemical equations
Answer:
Explanation:
1). Ca(NO₃)₂ + KI → CaI + K(NO₃)₂
This equation is incorrect.
When Ca⁺⁺ reacts with I⁻, final product is CaI₂
And when K⁺ react with NO₃⁻, final product is KNO₃
Hence the equation will be,
Ca(NO₃)₂ + KI → CaI₂ + KNO₃
Now we have to balance this equation.
Ca(NO₃)₂ + 2KI → CaI₂ + KNO₃
↓
Ca(NO₃)₂ + 2KI → CaI₂ + 2KNO₃
2). Ca(NO₃)₂ + KOH → CaOH + K(NO₃)₂
This equation is incorrect,
Since the reaction of Ca⁺⁺ with OH⁻ gives the final product Ca(OH)₂
And final product of K⁺ and NO₃⁻ is KNO₃
Therefore, the equation will be,
Ca(NO₃)₂ + KOH → Ca(OH)₂ + KNO₃
Now we will balance this equation by changing the coefficients of the molecules until the number of atoms on both the sides become equal.
Ca(NO₃)₂ + KOH → Ca(OH)₂ + 2KNO₃
↓
Ca(NO₃)₂ + 2KOH → Ca(OH)₂ + 2KNO₃
3). Ca(NO₃)₂ + Na₂C₂O₄ → CaC₂O₄ + 2Na(NO₃)₂
This equation is incorrect,
Since the reaction of Na⁺ and NO₃⁻ gives the final product NaNO₃.
Therefore, the correct equation will be,
Ca(NO₃)₂ + Na₂C₂O₄ → CaC₂O₄ + 2NaNO₃
This equation is in the balanced form.
Which is one way that a short-term environmental change will most likely affect organisms within an ecosystem? A)It will lead to larger populations. B)It will lead to speciation. C)It will lead to adaptation. D)It will lead to forced migration.
Answer:
D)It will lead to forced migration.
Explanation:
Forced migration is an involuntary, sudden movement of organisms from one geographical location to another. This is often in response to short term environmental changes such as drought, famine, etc
When an ecosystem suddenly comes under stress due to these short term environmental changes, organisms may not be left with any other choice but to move or go to new locations in the quest for survival. The organisms may not have left the ecosystem in the absence of such short term ecological stress. This is what is meant by forced migration.

Two oxide of sulphur,A and B were analyzed and the results obtained showed that in oxide A,3.50g of sulphur combined with 6.00g of oxygen and in oxide B,2.80g of sulphur combined with 9.55g.Show that this result illustrate the law of multiple proportion
Answer:
See Explanaton
Explanation:
The law of multiple proportions states that when two same elements form more than a compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.
Oxide A
3.50g of sulphur combined with 6.00g of oxygen
Oxygen:Sulphur = 6 : 3.5
Oxide B
2.80g of sulphur combined with 9.55g
Oxygen : Sulphur = 9.55 : 2.8
Therefore:
The ratio of Oxygen to Sulphur in Oxides A and B is:
[tex]\dfrac{\text{Oxygen}}{\text{Sulphur}} \implies \dfrac{6}{3.5}:\dfrac{9.55}{2.8} = \dfrac{1.7}{1}:\dfrac{3.4}{1}=1:2[/tex]
Ratio of Oxygen=1:2
There is exactly twice in Oxide B as in Oxide A.
This result illustrates the law of multiple proportions.

A 75 lb (34 kg) boy falls out of a tree from a height of 10 ft (3 m). i. What is the kinetic energy of the boy when he hits the ground? Round your answer to the nearest joule. ii. What is the speed of the boy when he hits the ground? Round your answer to two significant figures. iii. Using the conversion factors of 1 m = 1.094 yd and 1 mi = 1760 yd, calculate the speed of the boy in miles per hour when he hits the ground.
Answer:
Kinetic energy of boy just before hitting the ground is [tex]\approx[/tex]1000 J.
Speed of boy just before hitting the ground is 7.67 m/s
or 17.16 mi/hr.
Explanation:
Given that:
Mass of boy = 75lb = 34 kg
Height, h = 10ft = 3m
To find:
Kinetic energy of boy when he hits the ground.
As per law of conservation of energy The potential energy gets converted to kinetic energy.
[tex]\therefore[/tex] Kinetic energy at the time boy hits the ground = Initial potential energy of the boy when he was at the Height 'h'
The formula for potential energy is given as:
[tex]PE = mgh[/tex]
Where m is the mass
g is the acceleration due to gravity, g = 9.8 [tex]m/s^2[/tex]
h is the height of object
Putting all the values:
PE = [tex]34 \times 9.8 \times 3 \approx 1000\ J[/tex]
Hence, Kinetic energy is [tex]\approx[/tex]1000 J.
Formula for Kinetic energy is:
[tex]KE = \dfrac{1}{2}mv^2[/tex]
where m is the mass and
v is the speed
Putting the values and finding v:
[tex]1000 = \dfrac{1}{2}\times 34 \times v^2\\\Rightarrow v^2 = 58.82\\\Rightarrow v = 7.67\ m/s[/tex]
Given that:
1 m = 1.094 yd and 1 mi = 1760 yd
[tex]\Rightarrow 1609\ m = 1\ mi[/tex]
Converting 7.67 m/s to miles/hour:
[tex]\dfrac{7.67 \times 3600}{1609}=17.16\ mi/h[/tex]
What was done to the linear parent function, f(x) = x, to get the function
g(x) = 1/6 x
Answer:
Vertically Shrunk by a factor of 1/6
Explanation:
Parent Formula: f(x) = a(bx - c) + d
a - vertical shrink/stretch and x-reflections
b - horizontal shrink/stretch and y-reflections
c - horizontal movement left/right
d - vertical movement up/down
Since we are only modifying a, we are dealing with vertical shrink/stretch:
Since a < 1 (1/6 < 1), we are dealing with a vertical shrink of 1/6.
Since a > 0 (1/6 > 0), we do not have a reflection over the x-axis.
