Why is it useful to model systems that use energy?

Chemistry
1 answer:
Airida [17]3 years ago
7 0

Answer:

Energy modelling can be described as a system to make simulations or computerized models of systems which use energy. This makes it easier to analyze and access such systems which use energy. By this approach, there are lesser chances for the energy to be wasted and fewer chances for any energy-related experiments to go wrong. As such kind of experiments can be dangerous hence it is essential that models be made first.

How many grams of water do you need to weigh if a reaction requires 5 moles of h2o
rewona [7]

One mole of water weighs 18 grams. H₂O is composed of 2H= 2 and 1 0=16 adding gives you 18. number of moles= mass/ Relative Molecular Mass

Therefore, mass= Relative Molecular Mass×number of moles

                           = 18×5 moles

                           = 90 grams

Determine the molarity of 1.2 mol KCl in 1.1 L of a solution?
victus00 [196]

Answer:

1.1 M

General Formulas and Concepts:

  • Molarity = moles of solute / liters of solution

Explanation:

<u>Step 1: Define variables</u>

1.2 mol KCL

1.1 L of solution

M = unknown

<u>Step 2: Solve for Molarity</u>

  1. Substitute:                    M = 1.2 mol/1.1 L
  2. Evaluate:                       M = 1.09091

<u>Step 3: Check</u>

<em>We are given 2 sig figs. Follow sig fig rules.</em>

1.09091 M ≈ 1.1 M
