Help me pleaseee

telo118 [61]

Answer: 11.25 moles of $O_2$ will be required to completely react with 2.25 moles of $C_3H_8$ .

Explanation:

The balanced chemical equation is:

$C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)$

According to stoichiometry :

1 mole of $C_3H_8$ require = 5 moles of $O_2$

Thus 2.25 moles of $C_3H_8$ will require= $\frac{5}{1}\times 2.25=11.25moles$ of $O_2$

Thus 11.25 moles of $O_2$ will be required to completely react with 2.25 moles of $C_3H_8$ .

Highlight the examples of radiation in the passage

BartSMP [9]

Answer:

Heating of the liquid water in a microwave.

Explanation:

Radiation is a form of heat transfer process that does not require a material medium rather it travels through space or vacuum in the form of electromagnetic waves or radiation. Heat transfer by radiation occurs in the form of microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. Some common examples of heat transfer by radiation is the warming of the Earth by the Sun, the warmth one experiences while sitting by the campfire, or the heating up of foods in a microwave.

Black bodies or surfaces are good absorbers as well as emitters of radiation. On the other shiny or white surfaces are poor radiators of heat.

From the above discussion on radiation, it can be seen that when the chemist takes the liquid and heats it in a microwave, the heat absorbed by the liquid to change to gaseous state is transferred through radiation.

HELP I TOTALLY FORGOT HOW TO DO THIS AND ITS DUE TOMORROW!! SOMEONE PLEASE HELP ME !

astraxan [27]

I would suggest you to use this instead.
Just place the known substance for example O2 Oxygen as they are asking you, and see where the diagram takes you.
So the answer would be 2 because you’d look at the coefficients of the balanced equation up there. H2O
I hope that was helpful, if you have more questions please ask!
