How many moles of SO2 are required to produce 0.45 mole CS2?
Kaylis [27]

Answer: The moles of carbon needed will be, 13.8 moles

Explanation: Moles of  = 5.52 mole

Now we have to calculate to moles of carbon.

The given balanced chemical reaction is,

From the balanced chemical reaction, we conclude that

As, 2 mole of  react to give 5 moles of carbon

So, 5.52 mole of  react to give  moles of carbon

Therefore, the moles of carbon needed will be, 13.8 moles

svet-max [94.6K]

Answer:

Explanation:

The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleaned from the third postulate in Dalton's series. Magnesium oxide decomposes into magnesium and oxygen. If 4.03 g of magnesium oxide decomposes to form 2.43 g of magnesium, what mass of oxygen gas is also released in the reaction

The word say magnesium oxide decomposes to magnesium and oxygen

the chemical symbols say

MgO-----------> Mg + O2  (since natural oxygen is diatomic)

the balanced  equation says

2MgO-------------->2Mg + O2

4.03 gm----------> 2.43 + ?0 gms

tour high school Algebra I class says

? = 4.03 -2.43 =1.60

your chemical analytcal lab says %mO in MgO = 16/40.3 = 39.7%

your calculator says

39.7/100 X 4.03 = 1.60

all of these prove the law of conservation of mass

The term "conservation of energy" means that the total amount of energy in a system isolated from the rest of the universe remai
il63 [147K]

Answer:

True

Explanation:

<u>The first law of thermodynamics</u> establishes a relationship between the internal energy of the system and the energy that it exchanges with the environment in the form of heat or work.

The first law of thermodynamics determines that the internal energy of a system increases when heat is transferred or work is done on it.

Like all the principles of thermodynamics, the first principle is based on systems in equilibrium.

On the other hand, it is likely that you have heard more than once that energy is neither created nor destroyed, only transformed. It is the general principle of energy conservation. Well, the first law of thermodynamics is the application to thermal processes of this principle.

The universe as a whole could be considered an isolated system, and therefore its total energy remains constant.
