What causes water pollution?
Answers
Answer:
Good answer below, just adding on
Explanation:
Runoff of chemical products, animal waste, and especially human waste products such as different types of trash like scrap metals and plastic greatly increase water pollution. Additionally, oil leaks and spills can also lead to severe water pollution. As a general statement I'd say that human activities that are not monitored and are either directly dumped into water ways or are caught in run off cause water pollution.

Which vein carries oxygenated blood back into the heart?
Answers
Answer:
The veins that carry oxygenated bloof back into the heart are the pulmonary arteries.
Explanation:
Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
Answer:

How is a mixture such as a plate of pasta different from a mixture such as air
Answers
Answer:
Well there is a lot of differences between the two. Its called homogeneous and Heterogeneous mixtures. Homogeneous mixtures are all the substances are evenly distributed throughout the mixture (salt water, air, blood). Heterogeneous mixtures are the substances that are not evenly distributed (chocolate chip cookies, pizza, rocks). So Pasta with sauce and meatballs is heterogeneous and air is homogeneous

when salt dissolves into water does it change its state
Answers
Answer:
no it doesn't change back
fine here When you dissolve salt in water, the sodium chloride dissociates in Na + ions and Cl - ions, which may be written as a chemical equation : NaCl (s) → Na + (aq) + Cl - (aq) Therefore, dissolving salt in water is a chemical change. The reactant (sodium chloride, or NaCl) is different from the products (sodium cation and chlorine anion).

Explanation:
Choice: [A]: "the mass multiplied by the acceleration of an object."
refers to: "force". " F = m*a " . → Rule out: Choice: [A].
___________
Choice: [B]: "the force on an object divided by the mass of an object."
refers to: "acceleration". " F /m = a ". → Rule out: Choice: [B].

a major use of magnesium oxide is as a refractory material.
explain in terms of structure and bonding, why magnesium oxide has a very high melting point.
[ this is 4 marks, please provide a good answer ]
[ giving brainliest + thanks on profile ]
Answers
Sodium oxide has a high melting point because of the strength ofits bonds. Due to having strong bonds, they cannot be broken veryeasily. Magnesium chloride is ionic compound. There is a strong electrostatic force of attraction between 2 chloride atoms and 1 magnesium atom.
Because it retains its strength at very high temperatures. It is considered a refractory material with a melting point of 6500 degrees F. It is also very non-reactive with other materials that might be put into the furnace and is even used to make crucibles - containers used to melt other substances.
The strength of ionic bonds usually depends on two factors - ionic radius and charge. Mg+2
and O−2 have charges of +2 and -2 respectively. This is larger than the charges of other ions like Na+ or NO-3. Magnesium ions and oxygen ions also have small ionic radius. Magnesium is in period 3 so its ion is smaller than that of calcium or barium. Oxygen ion is smaller than sulfide and fluoride. The smaller the ionic radii, the smaller the bond length and the stronger the bond. Therefore the ionic bond between magnesium and oxygen is very strong.
