False! The three states of matter are solid, liquid, and gas. We can not touch gas, so it can not be compressed.

White gold is an alloy that typically contains 45.0% by mass gold and the remainder is platinum. if 154 g of gold are available,

kvasek [131]

Percent by mass of platinum in white gold = 100% - 45% = 55%

We let x be the mass of the white which is 45% gold and 55% platinum.

Mass of gold in white gold = m x 0.45

where m is the total mass.

From the given above, we formulate the equation that would allow us to determine the mass of white gold.
154 = x (0.45)
x = 342.22 g

Then, we determine the amount of platinum.
mass of platinum = (342.22 g)(0.55)
mass of platinum = 188.22 grams

Thus, 188.22 grams of platinum is needed.

What does h20 mean on the periodic elements chart

Paladinen [302]

Answer:

The compound, H₂O, will not be found on the periodic table. This is because the periodic table only consists of individual elements. That being said, the elements found within H₂O are located on the periodic table. H₂O consists of hydrogen, denoted by the symbol "H", and oxygen, denoted by the symbol "O". The subscript (the 2) tells us that there are 2 hydrogen atoms located in the H₂O molecule.

Hydrogen is the first element listed on the periodic table and can be found in the top leftmost position. Oxygen is the eighth element on the periodic able and is located in the second row at the top right.

Fe(II) can be precipitated from a slightly basic (aq) solution by bubbling oxygen through the solution, which converts Fe(II) to

irina [24]

Answer:

0,051g of O₂ are consumed

Explanation:

The reaction of precipitation of Fe(II) is:

4Fe(OH)⁺(aq) + 4OH⁻(aq) + O₂(g) + 2H₂O(l) → 4Fe(OH)₃(s)

The moles of Fe(II) you have in 85ml of 0.075 M Fe(II) are:

0,085L×0,075M = 6,4x10⁻³ moles of Fe(II)

For the reaction, you require 4 moles of Fe(II) and 1 mol of O₂(g) to precipitate the iron. Thus, moles of O₂(g) you require are:

6,4x10⁻³ moles of Fe(II)× $\frac{1molO_2}{4molesFe(II)}$ = 1,6x10⁻³ moles of O₂(g)

These moles are:

1,6x10⁻³ moles of O₂(g)× $\frac{32g}{1mol}$ = 0,051g of O₂ are consumed

I hope it helps!

Dalton's Atomic Theory states A) that an atom is predominantly empty space. B) that matter is composed of small indestructible p

MrMuchimi

Answer:

1.B. That matter is composed of small indestructible particles.

2.A. Definite volume and definite shape.

3.B. An element

Explanation:

1.Dalton's atomic theory postulates:

1.It states that matter is composed of atoms that are indivisible and indestructible.

2.Atoms of an elements are identical .They have same size ,chemical properties and mass.

3.Atoms of one element are different from atoms of another elements.

4.Compounds are composed of atoms of more than one elements.The relative number of atoms of each element in a given compound is always same.

5.Atoms are not created or destroyed during chemical reaction.

Answer: B.That matter is composed of small indestructible particles.

2.Solid:It is that form of substance which have definite shape and definite volume.

Therefore, option A is true.

Answer:A. Definite volume and definite shape.

3.An element: it is a simpler substance .It cannot be broken into smaller substance by chemical reactions.

Therefore, option B is true.

Answer:B. An element
