The reaction that would take place if hot tungsten was
surrounded by air is that it would react to the oxygen in air to form non
conducting tungsten oxide and burns out instantly.
Answer:
A
Explanation:
With chemical reactions, there are various factors that affect the rate of the reaction. One of these is temperature.
When you raise the temperature, the reaction will move faster. Why? Temperature is directly correlated with the kinetic energy (basically, the energy that makes the particles move). Higher temperatures mean higher kinetic energies. Particles with higher kinetic energies move faster, which makes them more likely to collide. When collisions occur more frequently, the reaction follows through more quickly.
Thus, when Julissa warms the solutions, she will see that bubbling and white solid formation (the products of the reaction) occus faster. So, the answer is A.
Hope this helps!
Hello Mate!Well, there are
many definitions and descriptions of isolated systems, and
here are some of them:
1.
It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.
2.
It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.
I Hope my answer has come to your Help. Thank you for posting your question here in

We hope to answer more of your questions and inquiries soon.
Have a nice day ahead! :)

Taking into account the definition of molarity, the molarity of solution of sodium sulfate is 0.0732
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity is expressed in units
.
<h3>Molarity of solution of sodium sulfate.</h3>
In this case, you have:
- number of moles of sodium sulfate=
(being 142 g/mole the molar mass of sodiums sulfate) - volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:

Solving:
Molarity= 0.0732 
Finally, the molarity of solution of sodium sulfate is 0.0732
.
