Describe how you would prepare 350 ml of 0.100 m c12h22o11 starting with 3.00l of 1.50 m c12h22o11

To prepare 350 mL of 0.100 M solution from a 1.50 M solution, we simply have to use the formula:

M1 V1 = M2 V2

So from the formula, we will know how much volume of the 1.50 M we actually need.

 

1.50 M * V1 = 0.100 M * 350 mL

V1 = 23.33 mL

 

So we need 23.33 mL of the 1.50 M solution. We dilute it with water to a volume of 350 mL. So water needed is:

350 mL – 23.33 mL = 326.67 mL water

 

 

Steps:

1. Take 23.33 mL of 1.50 M solution

<span>2. Add 326.67 mL of water to make 350 mL of 0.100 M solution</span>

You begin pouring sodium chloride into a glass of water. For a long time, the sodium chloride just dissolves in the water, but s
Gennadij [26K]

Answer:

  • Option D:<u><em> The water is saturated</em></u>

Explanation:

Solubility is the term used to designate the maximum amount of a solute that can be dissolved in a given amount of solvent, at a given temperature and pressure.

At start, you begin with pure water in the glass. This water is a pure substance, not a solution.

When <em>you begin pouring sodium chloride into the glass of water,</em> a solution, i.e. a homogenous mixture of solute and solvent, is formed.

This solution, at first, is diuted, which means that it contanins just few grams (matter) of the solute dissolved.

As, more sodium chloride is dissolved, the solution becomes more concentrated but is unsaturated. At some point, the water cannot dissolve more sodium chloride, because it has reached the maximum amount that can contain at that temperature and pressure. Then, the solution is saturated.

You can tell that the water is saturated, ie it contaiins the maximum amount of sodium chloride that can be dissolved, by that amount of water, at the given temperature, because from that point, you will note that <em>as you pour more sodium chloride, it begins to pile up at the bottom of the glass</em>. Hence, the true statement is the letter D: <u><em>the water is saturated.</em></u>

The table above shows the number of protons in an Adam of four different elements according to the periodic table which of these
Maurinko [17]

Answer:

<u>The correct answer is X</u>

<u />

Explanation:

First have some idea about : Valency , Metals and non- metals.

Valency : It is the combining capacity of elements . The elements combine to other elements to gain stability . They always try to complete their octet(8 electrons in the outermost shell)

For Example : Na has 11 electron

Its electronic configuration is : 2 ,8 ,1 (2+8+1 = 11)

First shell contain maximum = 2 electron

2nd shell = maximum 8 electron

3 shell = maximum 18 electron

When it remove 1 electron from outermost shell , it is left with 2 ,8 configuration. Now , its outer most shell has 8 electron . so it get stable and show +1 valency.

When the element looses electron , it get positive charge

When the element gain electron it get negative charge

Metals: those element which show +1 , +2 , +3 valency are considered as metals

Non- metals = Those metals which show the valency of -1 , -2 ,-3 are considered as Non- Metals.

Questions:

1. T = 7 proton

Electronic configuration = 2 , 5

It gains (-ve charge) 3 electron to achieve complete octet(5+3 = 8) = -3 valency

It is non- metal

2. Q=15

Its electronic configuration = 2 ,8 , 5

It gains (-ve charge) 3 electron to achieve complete octet(5+3 = 8) = -3 valency

It is non- metal

3.X = 12

Its electronic configuration = 2 ,8 , 2

It loses (+ve charge) 2 electron to achieve complete octet( 2 , 8) = + 2 valency

It is  metal

4.Z = 17

Its electronic configuration = 2 ,8 , 7

It gains (-ve charge) 1 electron to achieve complete octet(7+1 = 8) = -1 valency

It is non- metal

<u>There is only one metal = X</u>

How many moles of bromine atoms are in 2.60 × 102 grams of bromine? 1. 0.0152 mol 2. 79.9 mol 3. 10.5 mol 4. 3.25 mol 5. 2.29 mo
Lera25 [3.4K]
Moles  =mass/ molar  mass  of  the  bromine  atom
the  molar  mass of  bromine  atom  is  79.904g/mol
mass=2.60  x10^2
therefore  the  moles  of  bromine  atom=
2.60  x10^2g/ 79.904g/mol  =3.25gmoles(answer  4)
