S + 6 HNO3 → H2SO4 + 6 NO2 + 2 H2O

Chemistry
1 answer:
mote1985 [20]2 years ago
4 0

Answer:

0.9grams

Explanation:

IF based on stoichiometry HNO3 to H2O is 6:2

Use 9 grams to find the moles of HNO3

9 grams/63g/mol=0.143 moles of HNO3

HNO3:H2O

6:2

0.143*2/6=0.048

H2O moles is 0.048moles

Mass of water =0.048moles*18g/mol=0.864g

To the nearest tenth=0.9grams.

What is the majority of a solution that contains 0.55 mole of HCl in water to make 1.50 L HCl solution?
PSYCHO15rus [73]

Answer:

0.367M

Explanation:

Molarity refers to the molar concentration of a solution. It can be calculated using the formula below:

Molarity = n/V

Where;

n = number of moles (mol)

V = volume (L)

According to the given information in this question;

n = 0.55 mole

V = 1.50 L

Molarity = 0.55/1.50

Molarity = 0.367M

Cierto elemento presenta dos isótopos cuyos números de masa suman 110 y cuyos números de neutrones suman 58 ¿Cuál es el número a
Anettt [7]

Answer:

El número atómico de cada uno de los átomos es 26

Explanation:

El número de masa es la suma de las masas del protón y el neutrón de un átomo.

El número atómico es el número de protones en el átomo.

Los parámetros dados son;

La suma del número másico de ambos átomos = 110

La suma de los neutrones = 58

Por lo tanto, sea el número de protones y neutrones en un isótopo = P₁ y N₁ y el número de protones y neutrones en el otro isótopo = P₂ y N₂

Tenemos;

 P₁ + N₁ + P₂ + N₂ = 110

N₁ + N₂ = 58

Por lo tanto;

P₁ + P₂ = 110 - (N₁ + N₂)

P₁ + P₂ = 110 - 58 = 52

Dado que los isótopos son del mismo elemento, sus protones serán iguales, por lo tanto;

P₁ = P₂

P₁ + P₂ = P₁ + P₁ = 2 × P₁

P₁ + P₂ = 52

2 × P₁ = 52

P₁ = 52/2 = 26 = P₂

El número atómico de ambos átomos es el número de protones en el átomo que es 26.

El número atómico del elemento del átomo es 26
