What is the volume of a sample of ammonia gas (NH3) if it contains 0.23 moles?​

Chemistry
1 answer:
LekaFEV [45]2 years ago
8 0

The volume of a sample of ammonia gas : 5.152 L

<h3>Further explanation</h3>

Given

0.23 moles of ammonia

Required

The volume of a sample

Solution

Assumed on STP

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So for 0.23 moles :

= 0.23 x 22.4 L

= 5.152 L

Necesito ayuda 3.- Anota las características que correspondan a cada tipo de hibridación. Tipo de hibridación, Arreglo geométric
ololo11 [35]

Answer:

ver explicacion

Explanation:

Los orbitales híbridos se obtienen mediante una combinación de orbitales atómicos.

En un átomo de carbono con hibridación sp3, el átomo de carbono es tetraédrico con un ángulo de enlace de 109,5 grados. Se pueden unir cuatro enlaces simples al átomo de carbono. Se pueden unir un total de cuatro átomos al carbono. Se puede unir un total de cuatro átomos al carbono, lo que ocurre en alcanos como el metano

Para un átomo de carbono con hibridación sp2, hay dos enlaces dobles y dos enlaces simples unidos al átomo de carbono que tiene una geometría plana trigonal con un ángulo de enlace de 120 grados. Se pueden unir un total de dos átomos al carbono. Se pueden unir un total de dos átomos al carbono. Esto ocurre en alquenos como el eteno.

Un átomo de carbono con hibridación sp tiene un ángulo de enlace de 180 grados y tiene una geometría lineal con un enlace triple y un enlace sencillo. Solo se puede unir un átomo al carbono. Esto ocurre en alquinos como el etino.

The Bay of Fundy in Nova Scotia, Canada is reported to have the largest tides in the world with high tide and low tide occurring
topjm [15]

The rate in m/s is 5.2 * 10^-4 m/s.

<h3>What is the rate in m/s?</h3>

We know that the speed is given as the ratio of the distance covered to the time taken. In this case, we have been told that the rate at which the tide rises is 6.08 ft per hour. We would now need to convert the rate from  6.08 ft per hour to m/s.

Now;

We know that;

1 foot/hour = 8.5 * 10^-5 m/s

6.08 ft per hour = 6.08 ft per hour * 8.5 * 10^-5 m/s/1 foot/hour

= 5.2 * 10^-4 m/s

The combustion reaction of isopropyl alcohol is given below: C 3 H 7 O H ( l ) + 9 2 O 2 ( g ) → 3 C O 2 ( g ) + 4 H 2 O ( g ) T
jek_recluse [69]

Answer:

the heat of formation of isopropyl alcohol is -317.82 kJ/mol

Explanation:

The heat of combustion of isopropyl alcohol is given as follows;

C₃H₇OH (l) +(9/2)O₂ → 3CO₂(g) + 4H₂O (g)

The heat of combustion of CO₂ and H₂O are given as follows

C (s) + O₂ (g) → CO₂(g) = −393.50 kJ

H₂ (g) + 1/2·O₂(g)   →  H₂O (l) = −285.83 kJ

Therefore we have

3CO₂(g) + 4H₂O (g) → C₃H₇OH (l) +(9/2)O₂ which we can write as

3C (s) + 3O₂ (g) → 3CO₂(g) = −393.50 kJ × 3  =

4H₂ (g) + 2·O₂(g)   →  4H₂O (l) = −285.83 kJ × 4

3CO₂(g) + 4H₂O (g) → C₃H₇OH (l) +(9/2)O₂ = +2006 kJ/mol

-1180.5 - 1143.32 +2006 = -317.82 kJ/mol

Therefore, the heat of formation of isopropyl alcohol = -317.82 kJ/mol.

For the reaction 6 Li + N2 → 2 Li3N , what is the maximum amount of Li3N (34.8297 g/mol) which could be formed from 14.18 mol (6
Yuki888 [10]
Moles Li = 3.50 g / 6.941 g/mol= 0.504
the ratio between Li and N2 is 6 : 1
moles N2 required = 0.504 /6=0.0840
we have 3.50 g / 28.0134 g/mol=0.125 moles of N2 so N2 is in excess
the ratio between Li and Li3N is 6 : 2
moles Li3N = 0.504 x 2 /6=0.168
mass Li3N = 0.168 mol x 34.8297 g/mol=5.85 g
