What is a beaker? can you also post a picture of what it ;looks like for me?

Answers

Answer 1

Answer: It's a piece of glassware used for handling liquids, usually in a laboratory,
although I use one as a coffee cup.

They have markings on the side, like a kitchen measuring cup, so you can
measure different amounts of liquid, and they have a lip for pouring.

They're also usually made of a special type of glass (borosilicate) so that
they won't crack when very hot liquids are poured in.

Here's a picture of a beaker with 200 milliliters of some blue stuff in it.

explain the difference of valence electron behavior between ionic bonds and covalent bonds. Give an example of each type of bond using the three main groups from the periodic table.

Answers

Ionic bonds are typically weak, non-directional primary bonds between atoms, where one cation donates its valence electrons to one or more anions. They often occur between a metal and a non-metal such as table salt (NaCl). Materials made from ionic bonds tend to be more ductile than covalent ones but are still more brittle than metallic bonded ones.
Covalent bonding is a strong type of primary bond that is highly directional as the atoms share their valence electrons. This makes the material less ductile. An example of this is carbon-carbon bonds in diamond.

4Fe + 3O2 → 2Fe2O3Iron combines with oxygen to form rust. Given the chemical reaction, how many grams of 4Fe + 3O2 would produce 10 g of rust?
A) 7 g
B) 10 g
C) 30 g
D) 70 g

Answers

Answer:

b) 10 g

Explanation:

Hi, the answer in simply: during a chemical reaction (that doesn't involve nuclear processes) the total mass involved is constant.

The total mass of the reactants equals the total mass of the products, althought the number of molecules may vary.

n(2Fe2O3)=10g/319.374amu=0.03mol

n(4Fe+3O2)=0.03 mol

m(4Fe+2O2)=Mn=319.374×0.03=9.58=10
