Rust on weathered rocks is caused by _____.saltation
oxidation
hydrolysis
abrasion

Answers

Answer 1

Answer: Rust on weathered rocks is caused by the process of oxidation. Oxidation is a process of chemical weathering that occurs when oxygen combines with minerals in rocks. rust occurs when oxygen combines with iron in rocks to form the reddish brown iron oxide.

Answer 2

Answer:

Answer: The correct answer is oxidation.

Explanation:

Rust is a reddish-brown colored compound which is formed by the oxidation of Iron to form ferric oxide. The formula for this chemical compound is $Fe-2O_3$

Oxidation is defined as the reaction in which addition of oxygen takes place.

The reaction for the formation of rust is given by the equation, we get:

$4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)$

By Stoichiometry,

4 moles of iron metal reacts with 3 moles of oxygen gas to form 2 moles of ferric oxide.

Hence, the correct answer is oxidation.

What causes water molecules to be attracted to each other? A. Polar covalent bonds inside each water molecule
B. Hydrogen bonds inside each water molecule
C. Ionic bonds between water molecules
D. Nonpolar covalent bonds between water molecules

Answers

Answer:

Both polar covalent bonds inside each water molecule and hydrogen bonds inside each water molecule are liable for attraction between water molecules.

Explanation:

Water is a polar protic molecule.
Due to large difference in electronegativity between oxygen and hydrogen atom, two O-H bonds in water molecule are polar.
Due to the presence of polar covalent bonds in water molecule, water molecules attract each other through oppositely polarized ends.
In water molecules, H atom is attached with highly electronegative oxygen atom. Hence hydrogen bonding interaction arises between water molecules.
So, both option (A) and (B) are correct

This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.

How are elliptical galaxies different from spiral galaxies?a. They contain older stars and less gas and dust.
b. They contain younger stars and more gas and dust.
c. They are bigger than spiral galaxies.
d. They are smaller than spiral galaxies.

Answers

Answer:

A. They contain older stars and less gas and dust.

Explanation:

There are three types of galaxies:

elliptical galaxies
spiral galaxies
lenticular galaxies

Elliptical galaxies are galaxies shaped like an ellipse, while spiral galaxies consist of a flat, rotating disk that contains stars, gas, and dust, and a central concentration of stars called the bulge.

The difference between elliptical and spiral galaxies is in the amount of gas and dust they contain. Spiral galaxies contain large amounts of gas and dust, which means that new stars are born very often. This makes them brighter than relatively dim elliptical galaxies, which contain less gas and dust. This is why fewer new and brighter stars are born in elliptical galaxies, leaving them with older, dimmer stars.
