How can you tell if an element is a solid,liquid,gas or synthetic
Tanzania [10]

It all depends on how high or low an objects melting point is. and solid, liquid, and gases are states of matter, you have to play with the temperatures of objects.

But most of the elements on the periodic table are solid at room temperature except gases hydrogen, nitrogen, oxygen, fluorine and chlorine, the “noble” gases helium, neon, argon, xenon, krypton and radon, and the liquids bromine and mercury. The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements cesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.

The mostly red pic are the solids, the pic with only two highlighted squared are liquids, the pic with the row of squares are the gases, and the last pic (with dark background) are the synthetic elements


Hope this helps.

A solution with a pH of 6 has a ______ difference in H ion concentration than a solution with pH of 10.
sergij07 [2.7K]

Answer:

9.999x10^-7M

Explanation:

First, let us calculate the concentration of the hydrogen ion in both cases:

For pH 6:

pH = —Log [H+]

6 = —Log [H+]

—6 = Log [H+]

Take the anti-log of —6

[H+] = 1x10^-6M

For pH 10:

pH = —Log [H+]

10 = —Log [H+]

—10 = Log [H+]

Take the anti-log of —10

[H+] = 1x10^-10M

The difference between the [H+] of pH 6 and [H+] of pH 10 is given by:

1x10^-6 — 1x10^-10 = 9.999x10^-7M

In 1901, Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. Fe(s) + 2 NiO(OH)(s)
AveGali [126]

Ans: Moles of Fe(OH)2 produced is 5.35 moles.

Given reaction:

Fe(s) + 2NiO(OH) (s) + 2H2O(l) → Fe(OH)2(s) + 2Ni(OH)2(aq)

Based on the reaction stoichiometry:

1 mole of Fe reacts with 2 moles of NiO(OH) to produce 1 mole of Fe(OH)2

It is given that there are:

5.35 moles of Fe

7.65 moles of NiO(OH)

Here the limiting reagent is Fe

Therefore, number of moles of Fe(OH)2 produced is 5.35 moles.

What mass of sodium sulfate is needed to make 2.5 L of 2.0 M solution?
Serjik [45]
D) 710 g

Step by Step:
Multiply 2.5 L by 2.0 M to solve for moles
2 mol/L • 2.5 L= 5 mol

Find formula weight of sodium sulfate

Na2SO4-142.04 g/mol

Na- 2(22.99)=45.98
S-32.06
O-4(16)=64

Multiply miles by formula weight

5 mole • 142.04 g/mol=710.2 g
