Describe the chemical reaction based on the chemical equation below. Also, explain whether the equation is balanced. NH3(g)+o2=NO(g)+H2O(I)

Answers

Answer:

2 moles of ammonia gas (NH₃) reacts with 5/2 moles of oxygen gas (O₂) to produce 2 moles of nitrogen monoxide gas (NO) and 3 moles of liquid water (H₂O)

Explanation:

The chemical equation is:

NH₃(g) + O₂(g)⇒ NO(g) + H₂O(I)

First, we have to distinguish which are reactants and which are products.

Reactants ⇒ left side: NH₃ (ammonia gas) and O₂ (oxygen gas)

Products ⇒ right side: NO (nitrogen monoxide) and H₂O (water)

Thus, ammonia gas reacts with oxygen gas to produce nitrogen monoxide gas and liquid water.

The reaction is not balanced, because it does not has the same number of atoms of each chemical element in both sides. To balance, we have to write a coefficient of 3 for H₂O, then a coefficient of 2 for NH₃ (to balance H atoms), then a coefficient of 2 for NO, and finally a coefficient of 5/2 for O₂ (to obtain 5 atoms of O in both sides):

2 NH₃(g) + 5/2 O₂(g)⇒ 2 NO(g) + 3 H₂O(I)

According to the balanced equation, 2 moles of ammonia gas (NH₃) reacts with 5/2 moles of oxygen gas (O₂) to produce 2 moles of nitrogen monoxide gas (NO) and 3 moles of liquid water (H₂O).

¡A que clasificación corresponden las sustancias que están formadas por un mismo tipo de átomos, es homogénea y no puede descomponerse por medios químicos?

Answers

Answer:

Elementos.

Explicación:

Los elementos son las sustancias puras que están formadas por el mismo tipo de átomos, es homogéneo y no se puede descomponer por medios químicos. El elemento tiene el mismo tipo de átomos que son similares en tamaño y forma. Es un tipo de materia pura que tiene solo un tipo de átomos y no se puede descomponer más porque no está hecha de dos sustancias, es solo una sustancia, por eso no se puede descomponer por medios químicos.

La formula quimica de la molecula de agua H20 , si H = 1 gramos y O = 16 gramos . Cual es su composicion porcentual ? 88,88 % de O y 11,11 % de H 88,88 % de H Y 11,11% de O 80 % de O Y 20 % de H 90% de O Y 10 % de H

Answers

Answer:

88,88 % de O y 11,11 % de H

Explanation:

La composición porcentual se define como la masa que hay de cada mol de átomo en 100g. Las moles de agua en 100g son:

Masa molar agua:

2H = 2*1g/mol = 2g/mol

1O = 1*16g/mol = 16g/mol

Masa molar = 2 + 16 = 18g/mol

100g H2O * (1mol / 18g) = 5.556 moles H2O.

Moles de hidrógeno:

5.556 moles H2O * (2mol H / 1mol H2O) = 11.11 moles H

Moles Oxígeno = Moles H2O = 5.556 moles

La masa de hidrógeno es:

11.11mol * (1g/mol) 11.11g H

La masa de oxígeno es:

5.556 mol * (16g / 1mol) = 88.89g O

Así, el porcentaje de O es 88.89% y el de H es 11.11%. La opción correcta es:

88,88 % de O y 11,11 % de H

b. 3.022 x 1023 molecules S,

c. 4.302 x 10 molecules S

d. 8.203 x 10' molecules S2

Answers

Answer: There are [tex]2.032 \times 10^{25}[/tex] molecules [tex]S_{2}[/tex] gas are in 756.2 L.

Explanation:

It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of  moles present in 756.2 L are calculated as follows.

[tex]Mole = \frac{Volume}{22.4 L}\\= \frac{756.2 L}{22.4 L}\\= 33.76 mol[/tex]

According to mole concept, 1 mole of every substance contains [tex]6.022 \times 10^{23}[/tex] molecules.

Therefore, molecules of S present in 33.76 moles are calculated as follows.

[tex]1 mol = 6.022 \times 10^{23}\\33.76 mol = 33.76 \times 6.022 \times 10^{23}\\= 2.032 \times 10^{25}[/tex]

Thus, we can conclude that there are [tex]2.032 \times 10^{25}[/tex] molecules [tex]S_{2}[/tex] gas are in 756.2 L.

What is the mass percentage of copper in a 250 g sample of brass. Brass is made of copper and zinc and copper content of the sample is 150 g

What happens to the hydrogen ion (H+) concentration as an aqueous

A)decreases
B)increases
C)remains constant
D)cannot be determined

Answers

Answer:

Explanation:

It can be determined by measuring the Ph. D is incorrect.

C: is wrong because if you are making something acidic, you are increasing the H+

B: is the correct answer.

A: pH decreases. H+ increases which makes the Ph decrease. It is an oddity of the formula that makes this happen.

B) increases

Explanation: As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls

A population of Esherichia coli is given time to grow for eight generations. The final population is 1,996,800 cells. What was the initial population in cells?

Answers

Answer:

7800 cells

Explanation:

The number of Escherichia coli cells N after n generations is given by

N = 2ⁿ × N₀ where N₀ = initial population

Now making N₀ subject of the formula, we have

N₀ = N/2ⁿ

Since n = 8 and N = 1,996,800 cells, substituting the values of the variables into the equation, we have

N₀ = N/2ⁿ

N₀ = 1,996,800 cells/2⁸

N₀ = 1,996,800 cells/256

N₀ = 7800 cells

So, the initial population of Escherichia coli cells is 7800 cells.

The titration should be stopped when the solution in the flask changes color and the new color remains even when the solution is gently shaken. True False​

Answers

The above given statement is true.

What is solution?

A homogeneous mixture comprised of two or more components is referred to as a solution. Because they are consistently scattered at the molecular or ionic level, the components in a solution are evenly mixed and have a constant composition.

Until the reaction between the two solutions is complete, a solution of known concentration is gradually added to a solution of unknown concentration in a titration. The endpoint, or point at which the reaction is finished, is often identified by a color change that takes place after an indicator is added to the solution being titrated.

The reaction has achieved its endpoint when the solution in the flask changes color, and the new color persists even after the solution is gently shaken. At this time, the titration should be halted. By doing this, it is possible to precisely determine the concentration of the unknown solution and the volume of titrant added to the solution.
