What is the ability for a substance to flow

Answers

The ability for a substance to flow is fluidity.

Which substances show flowing?

Only liquid and gaseous substances have the ability to flow from one point to other as they have weak intermolecular force in it.

Fluidity is the quantity which gives idea about the ability of that substance to flow. At normal conditions at room temperature, any substance has the tendency to distort its shape in order to flow or take the shape of the container it is enclosed in.

Hence the ability for a substance to flow is fluidity.

The empirical formula = the molecular formula = C₁₀H₂₀O

Further explanation

Given

m =  0.15 g menthol

V = 0.0337 L

T = 150 +273 = 423 K

P = 100.2 kPa =0.99 atm

Required

molar mass

The molecular formula

Solution

Ideal gas law :

PV=nRT

n=PV/RT

n=0.99 x 0.0337/0.082 x 423

n=9.6 x 10⁻⁴

n =  mass/Molar mass

Molar mass = mass/n

Molar mass = 0.15/9.6 x 10⁻⁴

Molar mass = 156.25 g/mol

The empirical formula of Menthol : C₁₀H₂₀O

(The empirical formula)n= molecular formula

(C₁₀H₂₀O)n=156.25

(12.011.10+1,007.20+15,999)n=156.25

Given the following reaction, how many liters of H2 gas are needed to form 35.5 grams of NH3?

N2 + 3H2 -> 2NH3

Answers

Answer:

170.4L

Explanation:

The reaction equation is given as:

        N₂  +   3H₂  →    2NH₃  

Mass of NH₃    =  35.5g

Problem:

How many liters of H₂ are needed to produce 35.5g of NH₃  

Solution:

To solve this problem, let us find the number of moles of NH₃;

           Number of moles  = [tex]\frac{mass}{molar mass}[/tex]

Molar mass of NH₃   = 14 + 3(1)  = 17g/mol

 So;

            Number of moles  = [tex]\frac{35.5}{17}[/tex]  = 5.07mole

From the balanced reaction equation:

               2 mole of NH₃   will be produced from 3 mole of H₂  

               5.07mole of NH₃ will produce  [tex]\frac{5.07 x 3}{2}[/tex]   = 7.61mole of H₂

At STP;

       1 mole of gas will occupy 22.4L

     7.61 mole of H₂ will occupy 7.61 x 22.4  = 170.4L

What number of cations is present in 1.17g of sodium chloride ?

Answers

Answer:

1.2 × 10^22 atoms.

Explanation:

Firstly, cations refers to the positively charged atom in the ionic compound, which is Na+.

Given the mass of NaCl as 1.17g, the number of moles of NaCl can be calculated this:

Molar mass of NaCl = 23 + 35.5

= 58.5g/mol

Mole = mass/molar mass

Mole = 1.17/58.5

Mole = 0.02moles

Using Avagadro's number, 6.022 × 10^23 atoms of Na+ are in 1 mole of NaCl.

In 0.02 moles of NaCl, there are 0.02 × 6.022 × 10^23 of Na+

0.1204 × 10^23 atoms

1.2 × 10^22 atoms of Na+ (cation)

B. It is greater than the original piece
C. It is less than the original piece
D. It cannot be measured
PLEASE HELP!! THANK YOU

Answers

Answer:

A. It's the same as the original piece

Explanation:

The piece of matter is the same as that of the original piece.

When the mass of the two new pieces are combined, it the same as the single and whole one.

Mass is the amount of matter contained within a substance.

When the whole is broken into two and there is no mass loss, the mass is retained when they are brought together again. In most cases mass is always conserved even physical changes.
