Consider the following reaction: 2 NO(g) + 5 H2(g) → 2 NH3(g) + 2 H2O(g) Which set of solution maps would be needed to calculate

Leto [7]

Answer : The correct option is, (I) $gNO\rightarrow molNO\rightarrow molNH_3\rightarrow gNH_3$

Solution : Given,

Mass of NO = 45.8 g

Mass of $H_2$ = 12.4 g

Molar mass of NO = 30 g/mole

Molar mass of $H_2$ = 2 g/mole

Molar mass of $NH_3$ = 17 g/mole

First we have to calculate the moles of NO and $O_2$ .

$\text{ Moles of }NO=\frac{\text{ Mass of }NO}{\text{ Molar mass of }NO}=\frac{45.8g}{30g/mole}=1.53moles$

$\text{ Moles of }H_2=\frac{\text{ Mass of }H_2}{\text{ Molar mass of }H_2}=\frac{12.4g}{2g/mole}=6.20moles$

Now we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

$2NO(g)+5H_2(g)\rightarrow 2NH_3(g)+2H_2O(g)$

From the balanced reaction we conclude that

As, 2 mole of $NO$ react with 5 mole of $H_2$

So, 1.53 moles of $NO$ react with $\frac{1.53}{2}\times 5=3.82$ moles of $H_2$

From this we conclude that, $H_2$ is an excess reagent because the given moles are greater than the required moles and $NO$ is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of $NH_3$

From the reaction, we conclude that

As, 2 mole of $NO$ react to give 2 mole of $NH_3$

So, 1.53 mole of $NO$ react to give 1.53 mole of $NH_3$

Now we have to calculate the mass of $NH_3$

$\text{ Mass of }NH_3=\text{ Moles of }NH_3\times \text{ Molar mass of }NH_3$

$\text{ Mass of }NH_3=(1.53moles)\times (17g/mole)=26.0g$

Therefore, the maximum mass of $NH_3$ produced 26.0 grams.

The compound, nah2po4, is present in many baking powders. what is its name? sodium phosphate sodium bephosphate sodium dihydroge

AlladinOne [14]

The compound NaH2PO4 name is

sodium dihydrogen phosphate

Explanation
This name is arrived at by using the IUPAC rules of naming compound

1. the metal (sodium)is named first followed by the ligand ( hydrogen and phosphate)

Ligand are molecules that are attached to the metal center.

2. ligand are named using alphabetical order(for our case h for hydrogen come before p for phosphate hence hydrogen is named first)

3. Prefix di is used since hydrogen are two

hence the name of the compound is Sodium dihydrogen phosphate

What happens when energy is released during atomic fission

Vesnalui [34]

Nuclear energy is called the energy obtained by the transformation of atomic nuclei, so small and heavy clusters of particles inside the atom. Nuclear energy can be produced in two ways, by cleavage or synthesis of nuclei. Heavy nuclei of radioactive elements such as uranium or plutonium, can be split into two nuclei. By splitting are released from the nucleus of neutrons that collide with other nuclei causing them to split and subsequent emission of neutrons. This is called a chain reaction. The condition calls self-sustaining nuclear reaction is slowing down neutrons. For this purpose, a special substance, called moderator. The neutrons collide with the molecules of the moderator precipitate heating speed while the moderator. The resulting heat heats the water so that a couple who drives a turbine generating electricity. Another way of producing nuclear energy is nuclear fusion, in which nuclei combine to light elements. So far, fusion, however, failed to carry out so that it can be applied to the economy as a source of energy.

The principal that states that an object at rest will stay at rest and that an object in motion will stay in motion is the law o

Bogdan [553]

Answer: Newton's first law

Explanation: The idea that objects only change their velocity due to a force is encapsulated in Newton's first law. Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.
