The three chemical properties of a penny

Penny ( Pennies: plural; refer to a number of individual coins)

A chemical property of a substance is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.

<h3>What is chemical property?</h3>

The chemical properties of a substance can be determined by performing experiments that use specific materials or processes with known characteristics.

The following are three chemical properties to consider when choosing an element to make coins:

Reactivity to water.

Reactivity to oxygen.

malleability.

It should malleable, ductile, and an extremely good conductor of both heat and electricity.

How many Liters of space will a 70.0g sample of CO2 occupy?

Tanzania [10]

Answer:

35.6 liters at STP

Explanation:

The molar mass of carbon dioxide is about 44.01 g/mol. The volume of a mole of ideal gas at STP is 22.4 L, so the volume of 70.0 g will be ...

(70.0g)/(44.01 g/mol)·(22.4 L/mol) ≈ 35.6 L

Which of these solids are most likely amorphous solids? Select all that apply. Rubber sugar plastic candle wax graphite glass.

Ostrovityanka [42]

The solids are characterized as amorphous and crystalline solids based on the arrangement of atoms. The solids that are amorphous are rubber, plastic, candle wax, and glass.

<h3>What are amorphous solids?</h3>

The solids have the arrangement of atoms in the lattice. The solids with an appropriate arrangement of atoms are crystalline solids. For example, sugar, graphite.

The solids with irregular arrangements of atoms in the lattice are amorphous solids. For example, glass, rubber.

Thus, the solids that are amorphous in nature are rubber, plastic, candle wax, and glass.

Why is Dalton credited with proposing the first atomic theory if Democritus was talking about atoms almost 2,200 years earlier?

german

Democritus *suggested* the existence of the atom, that everything was made up of tiny particles, but wasn't really able to get more specific than that. Dalton also theorized that everything was made up of indivisible particles, but went further basing his theory on actual scientific principles, such as the Law of Conservation of Mass and the Law of Constant Composition. He also said that atoms weren't created or destroyed in a chemical reaction, just rearranged. There's more to it than that, but basically, Dalton's theory was based more on science while Democritus' theory was too general to be useful in chemical situations.
