Hi,
That’s FALSE. An intensive physical property is one that is independent of the size of the sample. Mass, on the other hand, is an extensive physical property, because it is dependent on the size of the sample.

Answer:

False

Explanation:

Physical properties of matter can be broadly classified into two categories:

-Intensive property

-Extensive property

Intensive properties are independent of the size or mass of matter i.e. they do not change as 'quantity' of matter changes. This includes: density, temperature, pressure etc

Extensive properties, in contrast are mass dependent and change as the amount of matter changes. Some examples include: mass, volume etc

The statement that mass is an intensive physical property because it is dependent on the size of the sample is False, instead mass is an extensive property.

In experiment 1, how many moles of benzoic acid are present? how many moles of sodium bicarbonate are contained in 1 ml of a 10%

nexus9112 [7]

First, let us calculate the moles of solute or sodium bicarbonate is in the 1 ml solution.

moles = 1 mL * (1 g / 9 mL) = 0.11 moles

The molar mass of sodium bicarbonate is 84 g/mol, therefore the mass is:

mass = 0.11 moles * 84 g/mol

mass = 9.33 g

Ammonia (NH3) is one of the most common chemicals produced in the united states. it is used to make fertilizer and other product

Greeley [361]

Answer:

a) N2 is the limiting reactant

b) 1215.9 grams NH3

c) 2283.6 grams H2

Explanation:

Step 1: Data given

Mass of N2 = 1000 grams

Molar mass N2 = 28 g/mol

Mass of H2 = 2500 grams

Molar mass H2 = 2.02 g/mol

Step 2: The balanced equation

N2(g) +3H2(g) → 2NH3(g)

Step 3: Calculate moles N2

Moles N2 = mass N2 / molar mass N2

Moles N2 = 1000 grams / 28.0 g/mol

Moles N2 = 35.7 moles

Step 4: Calculate moles H2

Moles H2 = 2500 grams / 2.02 g/mol

Moles H2 = 1237.6 moles

Step 5: Calculate limiting reactant

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

N2 is the limiting reactant. There will be consumed 35.7 moles.

H2 is in excess. There will react 3*35.7 = 107.1 moles

There will remain 1237.6 - 107.1= 1130.5 moles H2

This is 1130.5 * 2.2 = 2283.6 grams H2

Step 6: Calculate moles NH3

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

For 35.7 moles N2 we'll have 2*35.7 = 71.4 moles NH3

Step 7: Calculate mass NH3

Mass NH3 = moles NH3 * molar mass NH3

Mass NH3 = 71.4 moles * 17.03 g/mol

Mass NH3 = 1215.9 grams NH3

THANK REAL HARD...... DO YOU THINK A TREE AND A BUSH IS THE SAME THING??????/ THE BOTH DO THE SAME THING SO ARE THEY THE SAME TH

kramer

Well, trees are over 20 feet tall and have trunks that are like in 2 inches and 4.5 feet about the ground. Bushes are smaller than the trees and usually have smaller, woody, bark leafs.

Well im gonna say it would be the same,but not in size.

Hope this helps
