7 0

Answer:

elements and compounds can only be liquids or solids, but mixtures can be solids, liquids or gases

Explanation:

Element: A substance that is made up of only one type of atom. Compound: A substance that is made up of more than one type of atom bonded together. Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.

Which of the following lists the elements in order of increasing malleability?
Juliette [100K]

The answer would be (B) Sb, Sn, Se.

The periodic table may look like a confusing checkerboard of elements, but they are categorized in more ways than you may know.

For malleability, we look for metals. Metals/metallic elements have characteristics like electrical conductivity, <u>malleability</u>, ductility, and other physical characteristics like luster. The more an element is metallic, the more of these characteristics it will have.

So to answer this question, you simply have to see what kind of elements these are:

Sb, 51 (Antimony): <em>Metalloid</em>

Sn, 50 (Tin): <em>Transition Metal</em>

Se, 34 (Selenium): <em>Non-Metal</em>

Therefore, Antimony will have more metal characteristics than the rest, putting it at the top. Selenium is a non-metal, so that goes at the bottom, and Tin will be second.

What is the pH of a solution with a concentration of 4.7 × 10-4 molar H3O+?
wlad13 [49]
The pH of a liquid substance is calculated through the equation,
                                       pH = -log[H3O+]
Substituting the given concentration of the hydronium ion to the equation above,
                                        pH = -log[4.7x10^-4 M]
The value of pH is equal to 3.33. Thus, the pH of the solution is approximately 3.33.
