Incomplete question. However, I provided a specific example of stewardship of the atmosphere.
Explanation:
First, note that the term stewardship refers to the belief that humans are obligated to take care and look after our environment (which includes the atmosphere.
An example of this is: deciding to change our mode of transportation: What this entails is that we may decide to switch to riding a bicycle to places rather than going by car. By so doing you will be reducing the number of greenhouse gases emitted into the environment as bicycles do not emit harmful gases when used.

Examine the layers of rock. Identify and explain which layer contains the youngest fossils.
Earth layers with fossiles in each labeled top to bottom A to D.
Answer:
Layer A is the youngest
Explanation:
It is at the top, it has all of the dinosaur bones which got buried after earth got hit with an asteroid and they went extinct. Layer D started it and all of these years dirt, soil, and fossils have been gathering making each layer before older and older.

The number of electrons in the first three energy levels for four neutral elements is shown in the table. The element with the highest ionization energy is-
Answer:
The correct option is;
Element 2
Explanation:
The ionization energy is the energy required to eject an electron from a gaseous ion or atom
The ionization energy increases across the period and increases up the group
The elements with the highest ionization energy are those that have the complete octet structure in their outermost shell, which are the noble gases
Therefore, given that element 2, which has the complete octet structure in the outermost shell, then it is an element of the noble gases which have the highest ionization energy in a period, and therefore has the highest ionization energy.
On the periodic table, the element with 10 electrons is Neon, with ionization energy of 2080.68 kJ/mol which is the second highest after helium, that has only 2 electrons.
The relative formula mass (M) of a Group 2 metal carbonate is 197
Relative atomic masses (Ar): C = 12
O = 16
Calculate the relative atomic mass (Ar) of the Group 2 metal in the metal carbonate
Name the Group 2 metal.
The relative atomic mass (Ar) : 137 and the element : Ba
Further explanationThe naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)
This nomenclature includes the naming of ion compounds, covalent compounds, and polyatomic
The molar mass of a compound is given by the sum of the relative atomic mass of Ar
M AxBy = (x.Ar A + y. Ar B)
Group 2 metals have a +2 charge : M²⁺
So the compound of metal carbonate : MCO₃
Ar C = 12, O = 16
M MCO₃ = (1.Ar M + 1. Ar C+ 3. Ar O)
[tex]\tt 197=1. Ar~M+1.12+3.16\\\\197=Ar~M+12+48\\\\Ar~M=137[/tex]
The element with relative atomic masses 137 is Ba
So the compound : BaCO₃

A snicker bar has 300. Kcal, how many Joules of energy does it contain?
Answer:
1255200J
Explanation:
1 cal = 4.184 J
1kcal = 4184 J
thus, 300 kcal= 4184 × 300
= 1255200J
= 1255.2 kJ
= 1.2552 MJ
The distinctive odor of vinegar is due to acetic acid, HC₂H₃O₂, which reacts with sodium hydroxide. If a 3.45 mL sample of vinegar needs 42.5 mL of 0.115 M NaOH to be neutralized, how many grams of acetic acid are in a 1.00 L bottle of this vinegar?
Answer:
Explanation:
CH₃COOH + NaOH = CH₃COONa + H₂O .
42.5 mL of .115 M of NaOH will contain .0425 x .115 moles of NaOH
= 48.875 x 10⁻⁴ moles NaOH
It will react with same number of moles of acetic acid
So number of moles of acetic acid in 3.45 mL = 48.875 x 10⁻⁴
number of moles of acetic acid in 1000 mL = 48.875 x 10⁻⁴ x 10³ / 3.45 moles
= 1.4167 moles
= 1.4167 x 60 gram
= 85 grams .
So 85 grams of acetic acid will be contained in one litre of acetic acid.

How many days will pass between a new moon and a full moon?
Answer:
30
Explanation:
im smart
Answer:
The longest duration between full moon to new moon (or new moon to full moon) lasts about 15 days and 14.5 hours, while the shortest duration between full moon to new moon (or new moon to full moon) lasts only about 13 days and 22.5 hours. New Moon appears higher on summer solstice than on winter solstice.

How does a cold trap catch pollutants in smog?
Answer:
A temperature inversion occurs when air near the ground is relatively cool, and there is a layer of warmer air above it. That upper layer of warm air keeps the cooler air from rising, and traps all of the pollution in the cooler, lower layer.

6. What is one way a star with much more mass than the sun can end up?
white dwarf
red giant
neutron star
red dwarf
Answer:
neutron star
Explanation:
A massive star (More massive than the star) will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different

pure sodium and chlorine are extremely dangerous, but when combined the result in substance that we use every day. How do you think the properties of sodium and chlorine change when they are combined to make sodium chloride?
Answer:
Explanation:
chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.
The properties of sodium and chlorine change when they are combined to make sodium chloride should be explained below.
Information regarding chlorine:chlorine comprises of 7 valence electrons while on other hand, sodium has 1. A full valence electron shell contains the 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive.
