Answer:
rise in temperature and the effect it has on our global weather patterns
Answer:
ΔE = 150 J
Explanation:
From first law of thermodynamics, we know that;
ΔE = q + w
Where;
ΔE is change in internal energy
q is total amount of heat energy going in or coming out
w is total amount of work expended or received
From the question, the system receives 575 J of heat. Thus, q = +575 J
Also, we are told that the system delivered 425 J of work. Thus, w = -425 J since work was expended.
Thus;
ΔE = 575 + (-425)
ΔE = 575 - 425
ΔE = 150 J
Answer:
<h2>1.11 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question we have
![density = \frac{35.3}{31.7} \\ = 1.113564](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B35.3%7D%7B31.7%7D%20%20%5C%5C%20%20%3D%201.113564)
We have the final answer as
<h3>1.11 g/mL</h3>

Answer:
Tend to keep the product concetration <u>low</u> and therefore drive the reaction <u>righward</u>
Explanation:
The fact the products of a reaction are quickly consumed by the next one would tend to keep the product concetration low and therefore drive the reaction righward (to the products).
This happens because the system will not achive equilibrium between the reactants and the product, and will keep producing it util the system achives equilibrium or the reactants dry out.
