Answer:

C A

Explanation:

The the number line that shows that two opposite numbers have a sum of 0 is 4 3 2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12. The correct option is B.

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in elementary mathematics.

Every point on a number line is assumed to be a real number, and every real number is assumed to be a point.

4 3 2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12

We can see from this number line that the inverse of each number is located at an equal distance from 0.

For example, the inverse of 3 is -3, which is the same distance from 0 as 3. Similarly, the inverse of -1 is 1, which is the same distance from 0 as -1.

Thus, the correct option is B.

Answer:

D. see which items stick to the magnet

Explanation:

To predict which items are magnetic, the students will have to test whether or not each item is attracted to the magnet. Only objects that are magnetic stick to a magnet, so all of the items that stick to the magnet should be magnetic.

Hopefully that's helpful! :)

Answer: The products will be copper and oxygen.

Explanation: Copper electorde is an active electrode so it constantly takes part in the electrolysis. Cathode is a pure copper negative electrode and anode is a impure copper positive electrode. So the copper present in the solution, along with the copper present in the anode will come off and go to the cathode. As a result, cathode gains copper. And the remaining impurities settle down in the bottom.

In the anode, oxygen will be given off because according to the order of discharge, if SO4 is present then the ions will stay in the solution and oxygen will be released. So at the end, solution of SO4 and H2O will be remaining while copper and oxygen is extracted.

The half equations are-

Cathode: Cu2+ + 2e- = Cu

Anode: Cu + 2e- = Cu2+

Something you might not know: The solution in electrolysis turns blue when copper goes to the cathode. So copper electrodes are also used in electroplating.

Answer:

Inside the Atom

Just like bricks are the building blocks of a home, atoms are the building blocks of matter. Matter is anything that has mass and takes up space (volume). All matter is made up of atoms. The atom has a nucleus, which contains particles of positive charge (protons) and particles of neutral charge (neutrons). Surrounding the nucleus of an atom are shells of electrons - small negatively charged particles. These shells are actually different energy levels and within the energy levels, the electrons orbit the nucleus of the atom.

Answer:

M=0.0297M

Explanation:

we know that molarity equals number of mole of solute over the volume of solution.

M=n/V but n=m/M

n=0.225g÷101g/mol =0.00223mol

M=0.00223mol/0.075l

M=0.0297M

Answer:

0.0297M

Explanation:

We will use the formula M= moles of solute/lites of solution.

First we need to figure out the Moles of the solute, to get this we first need the molar mass of KNO3 (potassimum nitrate).

The Molar Mass of potassimum nitrate is 101.103 g/mol
K - 1 x 39.09
N - 1 x 14.006
O - 3 x 15.999
KNO3 - 101.103 g/mol

Now we get the moles of the solute by doing.
0225g/ 101.103g/mol = 0.00223 mol

Put the answer into the orginal equation to get 0.00223mol / 0.045 L
Which equals to 0.0297M. This is also the correct amount of significant figures.

Answer:

A) HF (Hydrofluoric acid)

Explanation:

dw I gotchu. So first off there are three types of intermolecular forces of attraction: 1) London-Dispersion, 2) Dipole-Dipole, 3) Hydrogen-Bonding Attraction Forces. That is also ranked in increasing strength, with Hydrogen-Bonding Attraction Forces being the strongest. Every molecule has London-Dispersion forces present and all the diatomic molecules listed have dipole moments of a certain debye (or Coloumb-meter) value. Both are irrelevant here so dw about that. Lets look at the strongest attraction: the hydrogen-bonding one. Now, don't get confused bc all of these acids are bonded to H bc hydrogen-bonding attraction forces only occur when H is bonded to N, O, or F. So Process of Elimination, hydrofluoric acid (HF) has the strongest intermolecular forces of attraction.

Note: If you don't know what inter/intra molecular forces of attraction are, ill give u a quick summary. Intermolecular refers to electrostatic attractions between molecules while intramolecular refers to the actual bonds, single, double, or triple, binding the atoms together. Well there you have it, have a great day. :)

Answer:

meerkats

Explanation:

Answer:

We know the initial volume of the potassium nitrate solution is 1.0 mL and the initial concentration is 2.0 M, we also know that an unknown volume of water was added to the solution, which diluted our concentration down to a final value of 0.008 M. We are trying to find the final volume.

Here we can use this formula since the initial and final solutions are proportional. Before that let's define our variables.

[tex]M_1 = 2.0 M\\V_1 = \frac{1.0 mL}{1000} = 0.001 L\\M_2 = 0.008 M\\V_2 = \ ?[/tex]

[tex]M_{1}V_{1} =M_2 V_2\\[/tex]

[tex](2.0)(0.001) = (0.008)V_2\\\\\frac{(2.0)(0.001)}{0.008} = V_2\\\\V_2 = 0.25 L \ or \ (0.25 \ * \ 1000) = 250 \ mL[/tex]

Therefore you would have 0.25 L or 250 mL of your final solution.
