Answer:
6.2 g
Explanation:
<em>The mass of oxygen gas produced from 8.5 g CO2 would be </em><em>6.2 g</em><em>.</em>
First, let us look at the equation of the reaction:
From the equation, 6 moles of CO2 are required to produce 6 moles of O2.
<em>Recall that: </em><em>mole = mass/molar mass</em>
8.5 g of CO2 = 8.5/44.01 = 0.1931 mole of CO2
Since the ratio of CO2 to O2 is 1:1, 0.1931 moles of CO2 will produce 0.1931 moles of O2.
Hence, mass of oxygen produced = mole x molar mass
= 0.1931 x 32
= 6.2 g <em>to 2 significant digits.</em>
Assuming that the solution is simply an aqueous solution
so that it is purely made of NaClO4 (the solute) and water (the solvent), then
I believe the dissolved species would only be the ions of NaClO4, these are:
Na+
ClO4 -
Hi! My answer would be D, USA.
Explanation:
We are provided with 5 pieces of an address. They are as followed.
12 Riverdale Lane, Apartment A, San Jose, California, and USA.
Imagine each of the five parts of Beck's address represents Earth, the Milky Way, the moon, the solar system, or the universe, based on their sizes. Which of the following parts of Beck's address would represent the solar system?
If we have to plug in Earth, the Milky Way, the moon, the solar system, and the universe, (all based on size,) we would first start with what "Apartment A" would be in this scenario. Apartment A is the smallest piece we have to work with, and so is the moon. This leads me to believe that the Moon should be plugged into Apartment A. Now, 12 Riverdale Lane is most likely going to be the Earth, since it is the second smallest one on our list. San Jose would turn into the Sun, California represents the Milky Way, and USA represents the solar system.
I sincerely hope I helped!
Have a wonderful day :)

Well electrons are like electricity well it is partly if it went 3 sub levels the electrons would blow up some electricty<span />
