How many moles of O2 are required if 12 moles of CuFeS2 are consumed?

Answer:- 30 moles of oxygen are required if 12 moles of CuFeS_2 are consumed.

Solution:- The given balanced equation is:

2CuFeS_2+5O_2\rightarrow 2Cu+2FeO+4SO_2

From this balanced equation, there is 2:5 mol ratio between CuFeS_2 and O_2 .

We are asked to calculate the moles of O_2 required to react with 12 moles of CuFeS_2.

It's a mol to mol conversion and the set up for this would be as:

12 mol CuFeS_2(\frac{5 mol O_2}{2 mol CuFeS_2})

= 30 mol O_2

So, 30 moles of oxygen are required to react with 12 moles of CuFeS_2 .

Scientists use the theory of plate tectonics to understand the reasons volcanoes develop in
Firdavs [7]

Scientists use tectonics plates to understand the plates moving beneath the volcano.

<h3>What are tectonic plates?</h3>

According to the widely recognized scientific hypothesis known as plate tectonics, the Earth's lithosphere is made up of many sizable tectonic plates that have been steadily moving for nearly 3.4 billion years. Our globe would look drastically different if it weren't for plate tectonics. We have a stable climate, mineral and oil deposits, and oceans with a chemical balance that supports life thanks to the continuous recycling of the Earth's crust. Even now, every few hundred million years, it offers evolution a boost. The plates fit tightly against one another and sit on the heated, molten rock of the Earth's mantle like fragments of a broken shell. The plates move as a result of the heat produced by nuclear processes occurring inside the planet.

A sample of aluminum is placed in a 25-ml graduated cylinder containing 10.0 ml of water. the level of the water rises to 18.0 m
OLga [1]
To determine the mass of the sample, first find the volume difference after and before the aluminum was placed, the volume change is equal to the volume of the submerged object, in this case aluminum.

Then knowing volume of aluminum and the density of it, we can solve for the mass.

D = m/v

Dv = m

2.7 g/ml • 8 ml = 21.6 grams.

A child pushes a desk with a force of 15 N to the right. The desk accelerates to the right. Which of the following statements co
ratelena [41]

Answer:

The answer to your question is: number 1

Explanation:

Third law of Newton: says that for every action ,there is an equal and opposite reaction.

So, if the child is pushing an object to the right, it will recipe the same amount of force that he is exerting to the object but in opposite direction.

Number 2 and 3 are incorrect because, because the third law of Newton says "an equal and opposite reaction", not slightly more or less.

Number 4 is wrong, it is not in agreement with Newton's third law of motion.
