Explanation:

answer key

The molarity of the NaOH solution has been 0.0865 M.

The neutralization reaction of the Phosphoric acid and NaOH results in the formation of sodium phosphate and water.

The balanced chemical equation can be given as;

[tex]\rm H_3PO_4\;+\;3\;NaOH\;\rightarrow\;Na_3PO_4\;+\;3\;H_2O[/tex]

Thus for the neutralization of 1 mole of Phosphoric acid, 3 moles of NaOH has been used.

The moles of phosphoric acid in 0.100 grams sample:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

Moles of phosphoric acid = [tex]\rm \dfrac{0.100}{99}[/tex]

Moles of phosphoric acid = 0.001 mol

For the neutralization of 0.001 moles of NaOH:

1-mole Phosphoric acid = 3 moles NaOH

0.001-mole Phosphoric acid =0.003 moles of NaOH.

The molarity of the NaOH solution:

Molarity = [tex]\rm \dfrac{moles}{Volume\;(L)}[/tex]

Molarity of NaOH = [tex]\rm \dfrac{0.003}{0.035}[/tex]

Molarity of NaOH = 0.0865 M

The molarity of the NaOH solution has been 0.0865 M.

The grams of solute are required.

The mass of solute is 3.5 g

c =  Molarity = 0.1 M

M = Molar mass = 350 g/mol

V = Volume of solution = 100 mL = 0.1 L

n = Number of moles

m = Mass of solute

Molarity is given by

[tex]c=\dfrac{n}{V}\\\Rightarrow n=cV\\\Rightarrow n=0.1\times 0.1\\\Rightarrow n=0.01\ \text{moles}[/tex]

Molar mass is given by

[tex]M=\dfrac{m}{n}\\\Rightarrow m=Mn\\\Rightarrow m=350\times 0.01\\\Rightarrow m=3.5\ \text{g}[/tex]

The mass of solute is 3.5 g

Answer:

verical rays

Explanation:

The rays result in shorter days are the vertical rays.

Vertical rays are another name for direct rays. Rays that are straight overhead are referred to as vertical. Because the Earth is spherical, not all the Sun's rays hit it directly or vertically.

Vertical rays lose less heat because they cover a shorter distance. Slanted rays cover more ground and dissipate more heat. Sun's vertical rays fall between the Tropics of Cancer and Capricorn, along its migratory belt.

The length of a day is determined by the Earth's rotation around its axis, which has been accelerating during the past several decades. Our days have been becoming shorter due to this tendency.

Thus, vertical rays are responsible for shorter days.

The mass of PbI2 produced from a trace amount of 630mL of 0.268M KI solution is 39.2 g.

The equation of the reaction is; 2KI(aq)+Pb(NO3)2(aq) → PbI2(s) + 2KNO3(aq)​

From the question, number of moles of KI = 630/1000 L × 0.268M = 0.169 moles

Now;

2 moles of KI is required to precipitate 1 mole of PbI2

0.169 moles of KI is required to precipitate 0.169 moles × 1 mole/2 moles

= 0.085 moles

Mass of PbI2 = Number of moles of PbI2 × Molar mass

Mass of PbI2 = 0.085 moles × 461.01 g/mol

Mass of PbI2 = 39.2 g

Solve any question of Thermodynamics with:-

The specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

The specific heat capacity of the substance is calculated as follows;

Q = mcΔФ

where;

c = Q/mΔФ

c = (270) / (4.2 x 25)

c = 2.57 J/g⁰C

Thus, the specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

May I assume "ethanol acid is just ethanol (it has one slightly acidic H atom).  If so, the molar mass is 46.02 g/mole.

Explanation:

We have 30 cm^3 [30 ml] of 1.0 M (1 mole/liter)  [1 dm³ = 1 liter].

That is 1 mole/liter.  30 ml would contain (0.030 liter)*(1 mole/1 liter) = 0.03 moles.

The list which includes only bulk properties of matter is: C. boiling point, surface tension, vapor pressure.

What is matter?

Matter can be defined as anything that has mass and can occupy space.

Thus, any physical object or substance that is found on planet Earth is typically composed of matter.

The three (3) states of matter:

Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;

A bulk property of matter refers to the property that affects matter as a whole and they are listed as follows:
