What are the properties of metal, nonmetal, and mellaloids
Alchen [17]
Metals: generally shiny, malleable, and hard. They are good conductors of electricity.

Non-metal: do not conduct heat or electricity very well. Are typically brittle and are not easily mold into shapes.

Metalloids: <span>share characteristics of both metals and non-metals and are also called semimetals. Metalloids are typically semi-conductors, which means that they both insulate and conduct electricity. This semi-conducting property makes Metalloids very useful as a computer chip material. </span>

Calculate the molarity of the solution if 80.0 g of Kool-Aid is dissolved in 1.0<br> L of solution.
Serga [27]

Answer:

.234 M

Explanation:

Molarity, or concentration, of a substance is simply found by dividing the amount of that substance in moles by its volume. Here, we are given the mass (in grams) of Kool-Aid, so we need to convert that to moles. To do this, we simply need the chemical formula of Kool-Aid, which I have found to be C12H22O11. The molar mass of C12H22O11, using the periodic table, is 342.296 g. Next, take this molar mass and divide the given mass of Kool-Aid by it. You then get about .234 mol Kool-Aid.

Lastly, divide this by the volume of 1.0 L. You get .234 M as your final molarity.

How many moles of NO2 are equivlent to 74.3 grams of NO2N=14.01/ o=16.00?
lesantik [10]

The molecular mass of HNO_2 is: 1·1 + 1·14.01 + 2·16 = 47.01 g/mol.


Now we can convert the mass into mol of HNO_2:


74.3\ g\ HNO_2\cdot \frac{1\ mol}{47\ g} = \bf 1,58\ mol\ HNO_2

jek_recluse [69]

Answer:

a. the covalent and ionic bonds that hold elements and compounds together are broken and new bonds are formed

Explanation:

A chemical reaction is a process by which one or more substances, called reactants, are transformed into other substances with different properties, called products.

In a chemical reaction, the covalent and ionic bonds between the atoms that make up the reactants are broken. Then, the atoms rearrange themselves in another way, forming new bonds and giving rise to one or more different substances from the initial ones.
