Answer:
The first one is the answer
Explanation:
The reason is because the term 'solvent' can be defined as a substance that has the ability to dissolve a given solute to form a solution with it. An example is water because it can disolve most things, hence why its called the 'universal solvent'.

Describe what you know about this chemical formula: 4CO2
Answers
Answer:i hope im not too late
Explanation:
4CO2 also known as 4CO2 is a chemical compound occurring as an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. It also helps trap earths heat inside the earth so i doesnt escape back to outer space.
yourwelcome goodluck ill peel my eyes out if need help again- an 8th grader :p
Carbon dioxide is formed by the covalent bonding of carbon and two oxygen atoms. Thus it is a having the formula CO₂. 4CO₂ means 4 moles of carbon dioxide.
What is carbon dioxide?Carbon dioxide is an inorganic gas formed by the covalent bonding of carbon and oxygen. The valency of carbon is four and the valency of oxygen is two. Thus carbon shares its electrons two to each oxygen.
Each oxygen in turn shares its two electrons with carbon. Thus both the atoms attains stability. Carbon dioxide is a nonpolar compound with the formula CO₂. Thus one mole of carbon is represented as CO₂.
One mole of CO₂ weighs 44 g. Hence, the molar mass of carbon dioxide is 44 g/mol. As any other compounds one mole of carbon dioxide contains Avogadro number of atom or 6.022 ×10²³ CO₂ molecules.
4 CO₂ indicates 4 moles of CO₂ having 4 × 6.022 ×10²³ =24.08 ×10²³ molecules.

Answer:
Compounds are formed because of chemical bonding between two elements. Mixtures are formed when substances are physically mixed with one another. Compounds are basically of three kinds: Ionic, metallic and covalent.
Explanation:
I hope this helps! :)
Answer:
Elements are substances that are made up of only one type of atom. They cannot be broken down into anything simpler.
When two (or more) elements are chemically joined together they form compounds.
A mixture contains two or more substances that are not chemically joined together and can be separated.

Identify/describe how the process of physical weathering breaks down materials at the Earth's surface (by the following change agents: water movement, freezing, abrasion/pressure, exfoliation. plant growth, and animals).
Explain the role of each factor in chemical weathering (water, acid, and air).
Answers
Answer:
Exfoliation: When temperature of rocks rapidly changes that can expand or crack rocks.
Freeze-Thaw: when water gets into a crack, and it freezes ; the crack gets wider
Plant Growth: this is when a seed falls into a crack in a rock, and breaks apart the rock with its roots.
Animals: small animals like moles and mice can burrow into a rock and crack it open

The temperature of a 100 mL sample of pure water is 25°C. This is a measure of--
F the amount of chemical energy stored in the water molecules.
G the amount of heat released when water molecules react
H the average kinetic energy of the water molecules
J the total potential energy of the water molecules
Answers
The temperature of a substance is a measure of the average kinetic energy of the molecules in the substance. Hence, option H is correct.
What is average kinetic energy?The average kinetic energy of all the molecules is assumed to be directly proportional to the absolute temperature of the gas.
Temperature measures the average kinetic energy of the particles in a substance.
Thermal energy measures the total kinetic energy of the particles in a substance.
The greater the motion of particles the higher a substance's temperature and thermal energy.
The kinetic energy of a moving molecule, like that of any moving object, is the energy associated with its motion.
Hence, option H is correct.

When you have a pot of water on the stove, heat is transferred to the water. Describe the behavior of the water molecules and how temperature is affected.
Answers
Answer:
The water molecules are faster in their movement, and the temperature of the water and the molecules are increasing.
Explanation:
Answer: Temperature causes water molecules to move more quickly.
Explanation: Because each individual molecule has more energy as it gets hotter If you get water hot enough, the molecules move so much that the hydrogen bonds that hold them together start to break and the water becomes a gas, water vapor.

A.The formula is a molecule but not a compound
B.There are 18 molecules in this formula
C.There are 2 molecules in this formula

Your answer is C (I think I'm not absolutely sure)
Explanation:
There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. The correct option is option C.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Covalent compounds are formed by covalent bond and ionic compounds are formed by ionic bond. Covalent bond is formed by sharing of electron and ionic bond are formed by complete transfer of electron. Ionic bonds are stronger than covalent bonds.
