Which compound is an acidic oxide?
Aaluminium oxide
carbon dioxide
copper(II) oxide
magnesium oxide
Answer:
Carbon dioxide
Explanation:
Metal oxides are basic and Non metal.oxides are acidic.
Al, Be, Zn,Sn ,Pb oxides are amphoteric so they show both acidic and basic properties.
From the above answers Al, Cu and Mg are metals so their oxides are acidic while Carbon is a non metal.so CO2 is an acidic oxide

Explanation:
Distinguish between the first, second, and third ionization energies of an atom. b. How do the values of successive ionization energies compare
Answer:
The third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.) And 2nd ionization energy is higher than 1st ionization energy, 3rd is higher than 2nd, and so forth.

What is fitness?Fitness is defined as to be able to go about one's everyday activities without difficulty, without getting exhausted, and with enough energy to spare for leisure. Body composition, flexibility, muscular strength, muscular endurance, and cardiorespiratory endurance are the five facets of physical fitness. Physical activity can strengthen your bones and muscles, help you maintain a healthy weight, increase your ability to carry out daily tasks, and improve your cognitive health.
Exercise is defined as a bodily action that maintains or improves physical health and wellness overall. Exercise science is a field that investigates movement as well as the corresponding functional reactions and adaptations.
Thus, the result he hope for he should be happy with himself after following a strict diet and exercise routine.

Answer:
O-H
Explanation:
It is polar covalent bond, because the hydrogen atom has electronegativity about 2.6, and the oxygen atom, electronegativity about 3.6. When the difference in electronegativity of the atoms is between 0.4 and 1.7, the result is a polar covalent bond.
How do weak intermolecular bond strengths affect the melting and boiling point of a substance?
The melting point is lower, but the boiling point is higher.
Both the melting point and boiling point are lower.
The melting point is higher, but the boiling point is lower.
Both the melting point and boiling point are higher.
Considering the definition of intermolecular bond, the correct answer is second option: Both the melting point and boiling point are lower.
The molecules of covalent compounds can be held together through electrostatic interactions known as "intermolecular forces", which are characterized by holding more than one molecule together. Therefore, they are related to chemical bonds, which have the goal of making molecules stick together or separate.
In other words, intermolecular forces or bonds are those interactions that hold molecules together. These are electrostatic forces.
The presence of these forces explains, for example, the properties of solids and liquids.
They differ from intramolecular forces, because of these, they correspond to interactions that hold the atoms in a molecule together. In general, intermolecular forces are much weaker than intramolecular forces.
On the other side, the melting point is the temperature at which a substance goes from solid to liquid at a given pressure. Similarly, the boiling point is the temperature at which the substance passes from a liquid to a gaseous state.
Finally, the more intense the intermolecular forces, the higher the melting point and the boiling point of a substance because these are the forces that must be overcome to separate them.
In summary, the correct answer is second option: Both the melting point and boiling point are lower.

What are the similarities and differences between living on Earth versus living in space?
find 5 points for each section
Answer:
Differences
• Space is everything in the universe beyond the top of Earth's atmosphere - The moon, Stars, Milky way, etc.
• In space, no one can hear you scream. This is because there is no air in space, i.e, it's vacuum.
• Earth is a planet on solar system. It is the only planet where life exists!!
• Earth is also called "blue sky" cause it has 75% water.
Similarities
•They need oxygen for survival: Man, animals in earth and space need oxygen for survival.
•Water is also need to stay alive.
•Food is very paramount to both man, animal s and organisms.
•Shelter, we all ned a place to lay our head in other to be safe.
•Air everywhere in the atmosphere.
•Water, air, food and shelter are available on earth but their availability differs in space.
•Astronaut need to bring everything one need in space with him or her from Earth. They often recycle the things they bring.

The atmospheric conditions in earth and space is entirely different. Therefore the living in earth and space will be far different on many aspects such as adaptations, habits etc.
What are aliens?The living things that are believed to be exists in out of earth is called aliens. Some studies shows that there is a possibility to find exotic species living in space.
The study which deals with aliens is called exo-biology. The atmosphere thus, the presence gases, temperature, pressure, etc. will be different for space from that in the earth.
Hence, aliens may need not the presence of oxygen for living as well as the atmospheric conditions that maintains living in earth will not be there in space.
However, any living irrespective of earth or space need water and some kind of food to survive. Thus the presence of water in some planets opens the way to study the presence of livings there.

5) When rain falls to the earth, it just doesn't sit there. Instead, the rain water starts moving. Some of the precipitation seeps into the ground to replenishing groundwater. However, most of
it flows downhill as runoff. Runoff is important in filling rivers and lakes, but it also changes the landscape by erosion and can be a powerful mover. Flowing water is a powerful force,
capable of moving boulders and carving out canyons. Runoff has an impact on streams and rivers, but it also has an impact on the ocean system. What can you infer about the impact of
runoff on Ocean life? Choose ALL that apply.
A) Runoff drops a lot of sediment in the ocean, decreasing salinity.
B) Runoff builds up the coastline, depositing sediment, disrupting habitats of marine wildlife.
Runoff can lead to overgrowth of algae that can cause oxygen deprivation and create a dead zone.
D) Runoff carries pollutants into the ocean, causing illness and death of vulnerable marine populations.
) Runoff can carry bacteria, viruses and other pathogens from pet and livestock waste that can harm shellfish and other marine organisms.
Answer: Rain evaporates and this same process happens over and over again.

How much heat is absorbed when 25 g of water increases by 45 K?
4709.25 joules of heat are absorbed when 25 grams of water increases temperature by 45 K.
Let suppose that temperature change experienced by water is entirely sensible. Then, we can estimated the heat absorbed by the water sample ([tex]Q[/tex]), in joules, through this expression:
[tex]Q = m\cdot c \cdot \Delta T[/tex] (1)
Where:
[tex]m[/tex] - Mass of the water sample, in grams.[tex]c[/tex] - Specific heat of water, in joules per kilogram-Kelvin.[tex]\Delta T[/tex] - Temperature change, in Kelvin.If we know that [tex]m = 25\,g[/tex], [tex]c = 4.186\,\frac{J}{g\cdot K}[/tex] and [tex]\Delta T = 45\,K[/tex], then the heat absorbed by the water sample is:
[tex]Q = (25\,g)\cdot \left(4.186\,\frac{J}{g\cdot K} \right)\cdot (45\,K)[/tex]
[tex]Q = 4709.25\,J[/tex]
4709.25 joules of heat are absorbed when 25 grams of water increases temperature by 45 K.

I am sure its correct you can trust me becuase I took the test.
Answer:
The speed of the wave decreases.
