Answer:

Sulfur is characterized as a non-metal because it is consistent with the 3 physical properties listed for nonmetals. It is a poor conductor of heat and electricity because the electrons are not free to move.

Calculate the decrease in temperarure when 2.00 L at 20.0 degrees celsius is compressed to 1.00 L.

Serga [27]

I suspect that the pressure of this change is constant therefore

The equation is used from the combined gas law. (When pressure is constant both P's will cancel out P/P = 1)
V/T = V/T
Initial Change

Initially we have 2L at 20 degress what temperature will be at 1L.

2/20 = 1/T
0.1 = 1/T
0.1T = 1
T = 1/0.1
T = 10 degress celsius.

Hope this helps if you won't be able to understand what is the combined gas law just tell me :).

What is the percent of SO2 in H2SO4?<br> Help Please

Yakvenalex [24]

The percent of SO₂ in H₂SO₄ : 65.3%

<h3>Further explanation </h3>

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements

%Mass A in AxBy =

$\tt \dfrac{x.Ar~A}{MW~A_xB_y}\times 100\%$

For SO₂ in H₂SO₄ :

MW SO₂ = 32 + 2.16=64 g/mol

MW H₂SO₄ =2.1+32+4.16=98 g/mol

The percent of SO₂ :

$\tt \dfrac{64}{98}\times 100\%=65.3\%$

How many grams are needed to form 33.6 L of carbon dioxide

pychu [463]

It depends of the temperature and the pressure. If temperature and pressure are standard 1 mol forms 22.4 liter. So 33.6 liters form 33.6/22.4 = 1.5 mols.

Now calculate the molar mass of carbon dioxide: 12 g/mol + 2x16 g/mol = 44 g/mol

The mass of the 1.5 mols is 1.5mol * 44 g/mol = 66 g.

What is the chemical formula of palladium (iv)sulfate

Margarita [4]

<u>Answer: </u>The chemical formula for Palladium(IV) sulfate is $Pd(SO_4)_2$

<u>Explanation:</u>

Palladium is the 46th element of the periodic table which has an oxidation state of +4 (because it is a metal and will form positive ion) and sulfate is the polyatomic ion having a charge of -2 with formula $(SO_4^{2-})$

So, to write the formula of the compound, we do criss cross method in which oxidation state of each element or ion is given to the other combining atom which results into the formation of a neutral compound.

The chemical formula of the compound is $Pd(SO_4)_2$

The image is given below.
