Answer: the effect of acid rain on water resources is that aquatic animals can be injured by the acid rain because of all the aluminum concentrations found in the water

Explanation:

Answer:

option C= O(g) → O+(g) + e-

Explanation:

Definition:

" The ionization energy is the energy required to remove the electron from outer most shell"

First ionization energy:

"It is the amount of energy required to remove the very first electron from valance shell"

it is represented in following equation;

X (g) → X+(g)  + e-

The physical state (g) must be written because ionization process occur  in gaseous phase. The ionization energy always measured in KJ/mol. The ionization energies are always positive because electrons are attracted towards the nucleus and  energy is always require to remove the electron and to overcome the hold of nucleus.

Periodic trend:

As we move down the group the ionization energies decreases with the increase of atomic number because atomic size increases and hold of nucleus or nucleus attraction on valance electron became weaker. that's way less energy is required to remove the electron.

As we move left to right in periodic table the ionization energy increase with increase of atomic number because atomic radius decreases and electrons are attracted towards the nucleus that's way more energy is required to remove the electron.

First ionization energy of oxygen:

O8 = 1s2 2s2 2p4      (1st ionization energy= I.E.= 1310 kJ/mol

The electron is remove from 2p subshell.

The reaction that represents the first ionization of O is c. O(g) → O⁺(g) + e⁻.

The first ionization of an atom is the removal of the most loosely bound electron of an isolated neutral gaseous atom.

Which reaction below represents the first ionization of O?

a. O(g) + e⁻ → O-(g)

NO. It is not an ionization because an electron is gained rather than lost.

b. O⁺(g) + e⁻ → O(g)

NO. It is not an ionization because an electron is gained rather than lost.

c. O(g) → O⁺(g) + e⁻

YES. It concords with the definition of first ionization.

d. O⁻(g) + e- → O²⁻(g)

NO. It is not an ionization because an electron is gained rather than lost.

e. O⁻(g) → O(g) + e⁻

NO. It does not start with a neutral atom.

The reaction that represents the first ionization of O is c. O(g) → O⁺(g) + e⁻.

Answer:

1/5

-1/5

11/5

-11/5

1

-1

11

-11

Step-by-step explanation:

The Rational Root Theorem states that if a polynomial equation with integer coefficients has a rational root, then that root must be of the form p/q, where p is a factor of the constant term (in this case, 11) and q is a factor of the leading coefficient (in this case, 5).

Using this information, we can determine that the potential rational roots of the polynomial f(x) = 5x³-7x+11 are all of the following:

1/5

-1/5

11/5

-11/5

1

-1

11

-11

Note that this list includes all possible rational roots of the polynomial, but not all of these roots will necessarily be actual roots. To determine which of these potential rational roots are actual roots, we would need to test them by plugging them into the polynomial and solving for x.

Answer:

B. He praises the advantages of being frozen in time.

Explanation:

The speaker praises the advantages of being frozen in time in the main topic of the passage.

"Ode on a Grecian Urn." Is a poem which was composed by a notable English Romantic Poet with the name John Keats.The poem was written in May 1819 and published in Annals of the Fine Arts for 1819.

There are several other "Great odes of 1819), which includes "ode of indolence", "ode to a Nightingale","ode of Melancholy", and lastly "ode of Psyche".

The poem "Ode on a Grecian Urn." Is divided into five stanzas of ten lines each.

We can say the main topic in "Ode on a Grecian Urn" is expressed in the following option:

B. He praises the advantages of being frozen in time.

"Ode on a Grecian Urn"

This poem develops the theme of the transiency of life and mortality. In this particular excerpt, the speaker mentions how the figures will be there forever when he says, "nor ever bid the Spring adieu" and "For ever piping songs for ever new."

The figures painted on the urn, unlike us, will never grow old and die. The speaker sees that as something good. They are forever frozen in time, singing, dancing, feeling happy.
