Explanation:

Prior preparation is required in a location at risk of natural disasters, this includes a communication system and infrastructure aimed at protecting and educating society. Technology is extremely important for the prevention of natural disasters, through forecasting and monitoring systems it is possible to map and analyze the possible risks and anticipate them with the necessary solutions, such as removing a population from a certain location with a risk of drilling.

It is necessary for the population to be aware, understand the alerts and signals issued in case of risk and follow the guidelines of the trained authorities, in this way it is possible to mitigate the effects of natural disasters.

jeyben [28]

Hello!

This is the chemical reaction for the Haber Process:

N₂(g) + 3H₂(g) → 2NH₃(g)

From the chemical coefficients in this reaction and the molar masses, we can write the following conversion factor to calculate the grams of nitrogen that are needed to produce 325 grams of ammonia:

$325gNH_3* \frac{1 mol}{17,031 g}* \frac{1 mol N_2}{2 moles NH_3}* \frac{28,0134 g N_2}{1 mol N_2}=267,29 g N_2$

So, there are 267,29 g of N₂ required to produce 325 grams of ammonia.

Have a nice day!

Burning 87.81 grams of hexane will release __ g of water.

olchik [2.2K]

<h3><u>Answer;</u></h3>

<u>= 128.772 g of water</u>

2C6H14 + 13 O2 → 6CO2 + 14 H2O

<h3><u>Explanation</u>;</h3>

1 mole of Hexane contains 86 g

Therefore;

87.91 grams of hexane will contain

= 87.91 g/86 g

= 1.022 moles

The balanced reaction for the combustion of Hexane is given by

2C6H14 + 13 O2 → 6CO2 + 14 H2O

Therefore; the mole ratio of C6H14 :H2O is

= 2 : 14

= 1: 7

therefore moles of water from 1.022 moles of Hexane will be;

= 1.022 ×7

= 7.154 moles

Mass of water will be;

= 7.154 moles× 18

<u>= 128.772 g of water</u>

Ptrpared a solution of sodium chloride (NaCl) by measuring out 49.Umol of sodium chloride into 150. ML. Volumetric flask and fil

ArbitrLikvidat [17]

Answer:

The answer to your question is below

Explanation:

Data

Substance = NaCl

moles of NaCl = 49

volume = 150 ml

Process

Molarity is a unit of concentration that makes a relation of the moles of a substance and the volume.

Molarity = moles / volume (L)

1.- Convert 150 ml to L

1000 ml ------------------ 1 L

150 ml ----------------- x

x = (150 x 1) / 1000

x = 0.15 L

2.- Substitution

Molarity = 49 / 0.15

Molarity = 326. 7

I have a doubt if the number of moles is 49 moles or 49μmoles
