Answer:

The characteristics are as follows:

-It is microscopic.

-It contains three sub atomic particles namely: electrons, protons and neutrons.

-It is the smallest unit of any substance (except for living bodies since smallest unit of them is cell).

-When seen from microscope atoms appear to be blur, spheres.

-They form ions(by losing or gaining electrons) and molecules(by combining with itself or other atoms).

The first step in the process used to recover zinc metal from zinc sulfide ore is the reaction of zinc sulfide with oxygen gas t

Vikentia [17]

Answer : The mass of oxygen consumed in the reaction is 14.6 grams.

Explanation :

First we have to calculate the change in moles of oxygen.

Formula used :

$w=\Delta nRT$

or,

$\Delta n=\frac{w}{RT}$

where,

w = work done = 850.1 J

$\Delta n$ = change in moles of gas = ?

R = gas constant = 8.314 J/mol.K

T = temperature = 675 K

Now put all the given values in the above formula, we get:

$\Delta n=\frac{850.1J}{(8.314J/mol.K)\times (675K)}=0.152mol$

Now we have to calculate the mass of oxygen consumed.

The balanced chemical reaction is,

$2ZnS(s)+3O_2(g)\rightarrow 2ZnO(s)+2SO_2(g)$

Here, the volume changes of solids can be ignored.

From the balanced chemical reaction, we conclude that

The number of moles oxygen required for the complete reaction = 3

Change in mole of oxygen = 0.152 mol

Molar mass of $O_2$ = 32 g/mol

So,

The mass of oxygen consumed = 3 x 0.152 mol x 32 g/mol = 14.6 g

Therefore, the mass of oxygen consumed in the reaction is 14.6 grams.

How is the orbital configuration of neutral atoms related to the atoms chemical properties

timama [110]

Answer:

Explanation:

Chemical properties of atoms relies solely on the number of electrons they contain, more particularly, the valence or outermost electrons in the orbit round the nucleus of an atom.

A neutral atom is one that has not gained or lost electron or even shared electrons with any other atom.

On close examination of how electrons are distributed in the orbits of an atom, we can know if an atom will gain or lose electrons in a reaction. This is very important in determining the chemical properties of an atom.

What will happen when a tree fell in a river

beks73 [17]

It's depending on what size of the tree it is. For example, if the tree is large it will block most of the water that runs through. If the tree is small it shouldn't do as much besides block a little amount of water and it will probably go down stream.
This is based on my thinking
