How does energy from the sun affect temperatures on the Earth?

For the reaction C6H6 + ? O2 → ? CO2+? H2O , what is the maximum amount of CO2 which could be formed from 6.59 g of C6H6 and 6.6

Likurg_2 [28]

Answer: 3.52 grams

Explanation:

$2C_6H_6+15O_2\rightarrow 12CO_2+6H_2O$

Given moles:

moles of oxygen = 6.62

moles of $C_6H_6=\frac{\text {given mass}}{\text {molar mas}}=\frac{6.59g}{78g/mol}=0.08moles$

According to stoichiometry:

2 moles of benzene reacts with = 15 moles of oxygen

Thus 0.08 moles of benzene will react with = $\frac{15}{2}\times 0.08=0.6$ moles of oxygen

Thus benzene is the limiting reagent as it limits the formation of products and oxygen is the excess reagent.

As 2 moles of benzene produce = 12 moles of carbon dioxide

0.08 mole of benzene will produce = $\frac{12}{2}\times 0.08=0.48moles$ of carbon dioxide

Mass of carbon dioxide= $moles\times {\text {Molar mass}}=0.48\times 44=3.52g$

Thus 3.52 g of carbon dioxide are produced.

Which phrase is the best definition for the word common in environmental science?

andreev551 [17]

I believe that the best definition of the word common in environmental science is a typical resource. A typical resource is a resource that is not hard to find and is very common. The answer to the question will hence be A.
The answer could not be the other three choices because a shared resource is a resource that is used by more than one organism in the environment. A worthless resource is one that has no use in the environment while a rare resource is one that is hard to find.

nikdorinn [45]

Answer:

Explanation:

Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.

Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.

This reaction, just by definition is endothermic.

How do you determine the order of reactivity series?

Mademuasel [1]

The order of reactivity series is Most reactive metals are at the top while the least reactive metals are at the bottom.

A reaction series is a list of metals arranged in descending order of reactivity. The most reactive metals are on top and the least reactive metals are on the bottom. If there are any two metals in the column, the metal placed at the top of the column can displace the bottom metal from the brine.

The more reactive the metal the faster the reaction. Metals below hydrogen in the reaction sequence do not react with dilute acids. Platinum is placed below gold in the reaction sequence. The elements in the lower left corner of the periodic table are the most active metals in the sense that they are the most reactive.
