Since rusting is a chemical change, the chain changed its composition as a result of oxidation of iron to hydrated iron(iii) oxide

Chemical changes are changes which occur as a result of chemical reactions which occur in substances resulting in the production of new substances.

An example of a chemical change is rusting of iron.

Rusting of iron occurs as a result of the oxidation of iron when exposed to air and water.

The picture shows rusting of iron.

Therefore, the chain changed its composition as a result of oxidation of iron to hydrated iron(iii) oxide.

Answer:

Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.

Explanation:

Electron Affinity:

electron affinity is the ability of an atom to accept an electron. Unlike electronegativity, electron affinity is a quantitative measurement of the energy change that occurs when an electron is added to a neutral gas atom. The more negative the electron affinity value, the higher an atom's affinity for electrons.

Electron affinity generally decreases down a group of elements because each atom is larger than the atom above it (this is the atomic radius trend, discussed below). This means that an added electron is further away from the atom's nucleus compared with its position in the smaller atom. With a larger distance between the negatively-charged electron and the positively-charged nucleus, the force of attraction is relatively weaker. Therefore, electron affinity decreases. Moving from left to right across a period, atoms become smaller as the forces of attraction become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period.

Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius.

Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.

Take the given weight (784.616g) and divide it by the atomic weight of H2SO4.

The atomic mass can be found under the element symbol on the periodic table. You must add the atomic mass for each element in H2SO4 to get the total. The total atomic mass for H2SO4 will be about 98g.

Then divide the weight by this number.

784.616g/98g = 8.006 moles

Therefore, there is approximately 8 moles.

The second statement

Explanation:

Because it can't be broken by physical means

A compound is a pure substance because  its molecule cannot be broken down into simpler particles by physical means. Therefore, option B is correct.

A kind of matter with a predictable chemical composition and physical properties is referred to as a chemical substance. According to certain references, chemical substances cannot be physically divided into their component parts.

A pure material has a predictable chemical make-up. A material is the same everywhere it is sampled. The safest pure examples for chemistry homework are elements and compounds. Gold, silver, helium, sodium chloride, and pure water are a few examples.

Water only includes one kind of molecule, making it a pure substance. Only molecules made up of one oxygen atom joined covalently to two hydrogen atoms can be found in pure water.

Thus, option B is correct.

Answer:

The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.
