O Occurs in substances that have high melting points

Answer:

I think its epicenter

Explanation:

The epicenter is the point on the earth's surface vertically above the hypocenter, point in the crust where a seismic rupture begins.

Answer:

Covalent compounds have low forces of attraction between their molecules (i.e. one H2O molecule isn't as attracted to another H2O molecule than the oppositely charges ions are in an ionic compound). Little energy is needed to break their bonds, therefore they have low meting points. Hope this is what you are looking for!

Answer:

P = 1361.17 KPa

Explanation:

Given data:

Mass of sample = 3.0 mol

Pressure of sample = ?

Volume of gas = 5.0 L

Temperature of gas = 0°C

Solution:

Pressure of gas:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 8.31 KPa.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

0+273 = 273 K

by putting values,

P × 5.0 L = 3.0 mol × 8.31 KPa.L/ mol.K  × 273 K

P = 6805.89 KPa.L/ 5.0 L

P = 1361.17 KPa

Explanation:

Here, the actual yield of the reaction is given 5.9 gram. The theoretical yield obtained from the balanced equation is 23 g. Hence, the percent yield of gold is 25%.

The percent yield of a product in a reaction is the ratio of its actual yield to the theoretical yield multiplied by 100.  The theoretical yield is calculated from the balanced equation of the reaction.

The balanced equation for the given reaction is :

[tex]\rm 3 Mg + 2AuCl_{3} \rightarrow 2 Au + 3 MgCl_{2}[/tex]

The molar mass of Mg = 24 g/mol

mass of 3 moles of Mg = 72 g

mass of Au = 197.9 g/mol

mass of 2 moles of Au = 395.8 g

Hence, three moles or 72 g of Mg gives 395.8 g of Au. Thus, mass of Au that can be produced from 4.2 g of Mg is:

= (4.2 × 395.8)/72 = 23 g.

This is the theoretical yield of gold. Thus the percent yield can be calculated as follows:

percent yield = actual yield / theoretical yield × 100

                      = ( 5.9/23) × 100

                      = 25%.

Therefore, the percent yield of gold in this reaction is 25%.

Answer:

0.33%

Explanation:

So, from the question it is given that the mass of the hydrogen peroxide in percentage is = 3% that is to say there are 3.0grams of hydrogen peroxide in 100mL of water. Therefore, the number of moles of hydrogen peroxide = 3/ molar mass = 3/ 34.02 = 0.088 moles.

Also, the mass of hydrogen peroxide = number of moles × molar mass = 0.088 × 34.02 = 2.99grams. Hence, the percentage by mass = [2.99/100 mL 0f water] × 100 = 2.99%

Therefore, the error in percentage = [ (3 - 2.99)/3 ]% × 100 = 0.33%

The percent error in the calculation has been 0.34%.

The moles of Hydrogen peroxide in 3% solution has been:

3% solution = 3 grams in 100 ml.

The molecular mass of hydrogen peroxide = 34.02 g/mol

The moles of hydrogen peroxide can be given as:

1 mole = 34.02 g/mol

3 g/100 ml = 0.088 mol.

The moles of hydrogen peroxide has been 0.088 mol.

Mass of hydrogen peroxide in 0.088 mol has been:

Mass = Moles × molecular mass

Mass of hydrogen peroxide = 0.088 × 34.02

Mass of hydrogen peroxide = 2.99 grams.

% of hydrogen peroxide = 2.99%.

The error in the calculation can be given as:

Error = [tex]\rm \dfrac{Bottle\;-\;Experimental}{Bottle}\;\times\;100[/tex]

Error = [tex]\rm \dfrac{3-2.99}{3}\;\times\;100[/tex]

Error = 0.34%.

The percent error in the calculation has been 0.34%.

Given data:

Mass of Fe = 2.30 g

Moles of FeCl₃ produced = ?

Solution:

Chemical equation:

2Fe + 3Cl₂         →     2FeCl₃

Number of moles Fe:

Number of moles = mass/molar mass

Number of moles = 2.30 g/ 55.85 g/mol

Number of moles = 0.04 mol

now we will compare the moles of iron and iron chloride.

             Fe            :           FeCl₃

              2            :              2

            0.04        :           0.04

Thus, 0.04 moles of iron chloride are produced.

The number of moles that could be produced is 0.04 moles

Chemical equation:

2Fe + 3Cl₂         →     2FeCl₃

Number of moles Fe:

It should be

[tex]= mass\div molar mass\\ = 2.30 g\div 55.85 g/mol [/tex]
