Which of the following are also compounds? Select all that apply.
A.
H2O
B.
CuFeS2
C.
Cl
D.
Mg
E.
KCl
Water, copper ferrous sulphate and potassium chloride are the compounds. Therefore, option A, B and E are correct.
What are compounds ?A chemical compound is a substance that contains atoms from many chemical elements bonded together by chemical bonds. It is made up of numerous similar molecules. Therefore, a molecule made up of only one type of atom is not a compound.
When various atoms are linked or chemically bound together to form molecules, the result is a compound. Water is an example of a compound. Due to the chemical bonding of two hydrogen atoms and one oxygen atom, water is known chemically as H2O.
Substances that cannot be divided into less complex substances with differing properties are known as elements. The periodic table is an arrangement of elements according to their properties. A molecule is made up of two or more atoms. Compounds are molecules made up of more than one element.
Thus, option A, B and E are correct.

Tsunamis are huge waves that carry large amounts of energy across the ocean. They are often caused by underwater earthquakes. One a tsunami forms, the wave can travel hundreds of kilometers before reaching land. Are the water molecules that touch land the same ones that the earthquake initially moved? Why or why not?
Answer:
Some of them yes but some of them no.
Explanation:
When the tsunami moves across other bodies of water it initially gets bigger. When it is moving across the water it is picking up molecules as well as dropping them off. But the farther away the tsunami gets from the water the smaller it gets.
Some of the water on land may be initaited by earthquake or may be not.
What is tsunami?Tsunami is a natural disaster, which causes the large destroy of natural lands, forests, habitats of many living beings, etc.
As it is mention that tsunami is caused by the earthquake which is occured underwater and as a effect of this, waves of ocean can travel hundreds of miles before touching the land. So, it is not necessary the water molecules which touches the land after this disaster is always that ones which are initiated by the earthquake.
Because during the travelling process may be some water will again drop off in the ocean or some may get evaporate.
Hence, it may be the water initiated by the earthquake or may be not.

How are mixtures and solutions different?
1.Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.
2.Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.
3.Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.
4.Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.
Answer:
The answer is 4.

Which statements accurately describe parasite-host relationships? Check all that apply.
Parasites can live in or on their hosts.
Parasites benefit from their hosts.
Parasites are harmed by their hosts.
Parasites usually kill their hosts.
Hosts benefit from parasites.
Hosts are harmed by parasites.
Parasites can live in or on their hosts, they benefit themselves from their hosts and usually kill their hosts and hosts are harmed by parasites this is called parasitism.
What is Parasitism?A parasitism is a kind of symbiotic relationship in which two species lives in close association. In this association one species is benefited by harming the other species so as to derive nourishment and shelter. The species which causes harm is called as the parasite the species which is being harmed is called as host. In parasitism the parasitic as well as the host species evolve together. The parasite is adapted to live in the host body in adverse conditions too. Also the host is adapted to get rid from the parasite and attain a protection from the parasitic damage.
Therefore, first, second, fourth and sixth statements are correct.

what happens when a low air pressure seytem meets a high air pressure
Answer:
The temperature of the air drops to below freezing. 2. The air moves to the low pressure system, creating wind. 3.The precipitation is removed from the air. 4. The air starts blowing in an easterly direction.
Explanation:
Answer:
The slightly inward moving air in low pressure causes air to converge and since it can't move downward due to the surface, the air is forced upward, leading to condensation and precipitation as discussed earlier. The opposite occurs with high pressure.

Question 2 options:
only perpendicular to the motion of the wave.
both parallel and perpendicular to the wave.
only parallel to the motion of the wave.
Answer:
Explanation:
Waves are actually energy passing through the water, causing it to move in a circular motion. ... This phenomenon is a result of the wave's orbital motion being disturbed by the seafloor.
The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.
Will give brainly. The nucleus of an atom is made up of protons and neutrons. How does the number of these particles determine the property of the atom?
Answer:
proton and neutron
Explanation:
Protons and neutrons are found in the nucleus of an atom. They make up a majority of the mass of an atom. In fact, the mass number of an element is the sum of its protons and neutrons.
Answer:
Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is. The number of neutrons in a nucleus affects the mass of the atom but not its chemical properties. Thus, a nucleus with six protons and six neutrons will have the same chemical properties as a nucleus with six protons and eight neutrons, although the two masses will be different.
