Answer:

The correct answer is 2.33g of H_{2}O, A

Explanation:

We can use basic stoich to get this question.

To start, lets convert our grams to moles in order to use our equation. 5.38g of O_{2} = (\frac{5.38}{2*15.999}) moles = 0.168136 moles.

We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of O_{2} to moles of H_{2}O. This gets us 0.129335 moles of H_{2}O.

Now lets convert to grams of H_{2}O by multiplying by the molar mass of H_{2}O. .129335*(1.008*2+15.999) = 2.32997g of H_{2}O

What would happen if the earth magnetic field flips? <br><br> plz help
Mumz [18]

The end of the world as we know it could come in any number of ways, depending on who you ask. Some people believe global cataclysm will occur when Earth's magnetic poles reverse. When north goes south, they say, the continents will lurch in one direction or the other, triggering massive earthquakes, rapid climate change and species extinctions.

 

The most dramatic changes that occur when the poles reverse is a very large decrease of the total field intensity,

Earth's magnetic field takes between 1,000 and 10,000 years to reverse, and in the process, it greatly diminishes before it re-aligns. It's not a sudden flip, but a slow process, during which the field strength becomes weak, very probably the field becomes more complex and might show more than two poles for a while, and then builds up in strength and [aligns] in the opposite direction.

For the oxidation of glucose C6 H12 O6 + 602 -- 6H2O + 6C02, How many moles of oxygen will it take to consume 3.9 moles of gluco
Mamont248 [21]

Answer:

The answer to your question is 23.4 moles of Glucose

Explanation:

Data

moles of Oxygen = ?

moles of glucose = 3.9

-Balanced chemical reaction

           1C₆H₁₂O₆  +  6O₂   ⇒   6H₂O  +  6CO₂

Process

1.- To solve this problem, use the coefficient of the balanced chemical equation, and use proportions and cross multiplication.

           1 mol of C₆H₁₂O₆ -------------------- 6 moles of O₂

    3.9 moles of C₆H₁₂O₆ ------------------   x

                                  x = (3.9 x 6 ) / 1

                                  x = 23.4 moles

2.- Conclusion

3.9 moles of glucose consume 23.4 moles of oxygen

Sodium has an atomic number of 11 and has a net charge of 0. When sodium combines with chlorine, it has a net charge of +1. Why?
lana [24]
Sodium has an atomic number 11, it means there are 11 electrons in sodium atom and has a net charge zero what when it combines with chlorine it loses one electron and get charge of +1. when and atom loses an electron it gets positive charge and when atom gains electron it gets negative charge. chlorine makes an anion and sodium makes cation and they are oppositely charged so they react with each other.

Anybody good at chemistry that is willing to help?? If you could that'd be greatly appreciated!
serious [3.7K]

Answer:

The least similar to a real gas found in the environment would be B.

Explanation:

Standard Ambient Temperature/Pressure (SATP) is at 298.15K and 101.3kPa. It describes standard conditions and is often used for measuring gas density and volume using the Ideal Gas Law. The values least similar to theses ones would be the least similar in the gases in the environment.
