How many moles of CO2 are in 210 liters at STP of the compound​

Chemistry
1 answer:
Zina [86]2 years ago
8 0

Answer:

9.4 mol CO₂

General Formulas and Concepts:

<u>Chemistry - Gas Laws</u>

  • Using Dimensional Analysis
  • STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Explanation:

<u>Step 1: Define</u>

210 L CO₂ at STP

<u>Step 2: Identify Conversions</u>

22.4 L = 1 mol at STP

<u>Step 3: Convert</u>

<u />210 \ L \ CO_2(\frac{1 \ mol \ CO_2}{22.4 \ L \ CO_2} ) = 9.375 mol CO₂

<u>Step 4: Check</u>

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

9.375 mol CO₂ ≈ 9.4 mol CO₂

Energy can be .................. From one form to another................. Can be burned to make heat or electricity.
nataly862011 [7]

Answer:

transferred

Energy

Explanation:

Energy is the ability to change the state of bringing about a work leading to movement or generating electromagnetic radiation. There are actually many forms of energy. So, kinetic energy is a form of energy related to the movement of a body. The combustion, in turn, retrieves the potential energy chemical contained in fuels. Solar panels capture light energy to transform it into electrical energy.

A student has a 2.123 g sample of a hydrated salt. she heats it to drive off all the water. after heating to constant mass, the
morpeh [17]
The mass of hydrated salt - 2.123 g
mass of anhydrous salt - 1.861 g
mass that has been reduced is the mass of water that has been heated and lost from the compound thereby making the salt anhydrous.
therefore mass of water lost - 2.123 - 1.861 = 0.262 g
number of moles of water lost - 0.262 g / 18 g/mol = 0.0146 mol 
number of moles of salt - 1.861 g / 380.6 g/mol = 0.00490 mol 
molar ratio of moles of water to moles of salt 
molar ratio = 0.146 mol / 0.00490 mol = 2.98 rounded off to 3
for every 1 mol of salt there are 3 moles of water
therefore empirical formula - Cu₃(PO₄)₂.3H₂O

Which isotope has the greatest number of protons?
tino4ka555 [31]

Answer:

The isotope with the greatest number of protons is:

  • <u>option D:  Pu-239, with 94 protons</u>

Explanation:

The number of <em>protons</em> is the atomic number and is a unique number for each type of element.

You can tell the number of protons searching the element in a periodic table and reading its atomic number.

Thus, this is how you tell the number of protons or each isotope

Sample       Chemical symbol  Element       atomic number   # of protons

A Pa-238       Pa                         protactinium         91                        91

B U-240         U                          uranium                 92                       92

C Np-238       Np                        neptunium            93                       93

D Pu-239        Pu                        plutonium              94                       94
