Compared to a 0.1 M aqueous solution of NaCl, a 0.8 M aqueous solution of NaCl has a(1) higher boiling point and a higher freezing point
(2) higher boiling point and a lower freezing point
(3) lower boiling point and a higher freezing point
(4) lower boiling point and a lower freezing point

Answers

Answer 1
Answer: Answer 2, because when you add salt to something, it cools faster (ex. When you add salt to an ice chest so that it stays cold) and it takes longer to boil (ex. When you boil salt out of ocean water so that its safe to drink) therefore, the more NaCl in the solution, the more it will exibit these properties

What is scientific consensus?O a new scientific idea that was confirmed by the original researcher
an idea that has been changed due to new information
O a general agreement among scientists about a scientific idea
the understanding that knowledge in a particular area can be uncertain

Answers

The scientific consensus is a general agreement among scientists about a scientific idea. The correct option is C.

What is a scientific idea?

A scientific idea is the explanation or facts of science. It reveals the truth about the world. How the world works and the secrets of nature. It tells and gathers true information about the world.

The different aspects of life and the world are understood and studied by scientists. Different scientists work for different forms of life. The scientist's ideas change over the different evidence.

The generalized ideas of various scientists give and agree upon the different theories of the levels of science. The publication process and specialized field.

Thus, the correct option is C. a general agreement among scientists about a scientific idea.

    Enthalpy refers to the total energy of a system. Hope this helped!

Answer:   a. Enthalpy

Explanation:

If the reaction is at dynamic equilibrium at 500 K, which statement applies to the given chemical system?The forward and reverse reactions no longer occur.
The rates of the forward and reverse reactions are unequal.
The concentrations of the products and reactants do not change.
The forward reaction stops at 500 K.

Answers

The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.

A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.

If the reaction is at dynamic equilibrium at 500 K, the statement that applies to the given chemical system is The concentrations of the products and reactants do not change.

Which physical state of matter exhibits the greatest change in volume with changes or temperature or pressure?

Answers

It’s the gas physical state that shows the greatest change in volume and changes in temperature or pressure. Because gas is the matter that is composed of loose particles but can be compressed. Since gas contains loose molecules, the molecules can freely move in a certain object, so when physical change happens, it exhibit greatest change. Gas also follow the shape of its container and can expand in order to fill its container. It has no definite volume or shape.



Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).

Answers

Hello!

Determine the mass of 5.20 moles of C6H12 (gram-formula mass = 84.2 grams/mole).

We have the following data:

m (mass) = ? 

n (number of moles) = 5.20 moles

MM (Molar mass of C6H12) ≈ 84.2 g/mol

Now, let's find the mass, knowing that:

n = (m)/(MM)

5.20\:\:\diagup\!\!\!\!\!\!\!mol = (m)/(84.2\:g/\diagup\!\!\!\!\!\!\!mol)

m = 5.20*84.2

\boxed{\boxed{m = 437.84\:g}}\end{array}}\qquad\checkmark

_______________________

I Hope this helps, greetings ... Dexteright02! =)
Molar mass C₆H₁₂ = 84.2 g/mol

1 mole ---------- 84.2 g
5.20 moles ---- ?

Mass C₆H₁₂ = 5.20 * 84.2 / 1

Mass = 437.84 /1

= 437.84 g

hope this helps!

How to name alkane using iupac system

Answers

Naming an alkane through the IUPAC system is pretty simple
so all it is is (prefix for number of carbon) + ane
For the first four in this homologous series you have
 Meth- 1 carbon
 Eth- 2 carbons
 Pro- 3 carbons
 But- 4 Carbons
Onward you use the prefixes you know such as Pent, Hex, Hept, Oct, Non, Dec

So for an alkane with 3 Carbons it would be Propane, with 4 - Butane with 8- Octane etc.
