<span>The Helium gas will expand and rise into the surrounding the air as it is less dense and lighter air. Depending on the amount of helium and the size of the room the Helium could displace the breathable mix in the space and become a danger to health.</span>
Answer:
C. 3 Li
Explanation:
Nitrogen has 7 electrons, which you can find on a periodic table. Let's figure out what its valence is, or how many electrons are in its outer shell!
We know that the first shell is filled with 2 electrons. Then the next shell is filled when it has 8 electrons, but we've only got 7 - 2 = 5 electrons left.
So nitrogen N has 5 valence electrons. That means it wants to bind with something that can offer it <u>3 electrons to share.</u>
A. 2 Ca atoms have 2 * 2 = 4 valence electrons.
B. 1 H atom has 1 valence electron.
C. 3 Li atoms have 3 valence electrons. <em>This could be our winner! Check D anyways.</em>
D. 2 C atoms have 4 * 2 = 8 valence electrons.
So the only one that works is C. 3 Li atoms.
Answer is: <span>a. c6h14 and c10h20.
This pair will </span>most likely form a homogeneous solution because they are both nonpolar substances and "li<span>ke dissolves like".
Other pairs will not form homogeneous solution because nonpolar substances have low solubility in polar or ionic substances (for example LiBr is ionic and C</span>₅H₁₂ is nonpolar).
Answer:
To produce 1 mole of N2O required 1 mole of NH4NO3 . Hence, 60 grams of NH4NO3 are required to produce 33.0 g N2O

According to Avogadro's law, the two gases will have equal number of molecules.
<h3>Avogadro's law </h3>
From the question, we are to determine how the two gases would compare according to Avogadro's law
First, we will state the Avogadro's law
<em>Avogadro's law</em> states that "equal volume of all gases at the <u>same temperature and pressure</u> contain the same number of molecules"
Now, from the given information
We have 2 liters of hydrogen gas and 2 liters of oxygen gas at the <u>same temperature and pressure</u>
According to Avogadro's law, gases that are equal in volume and are at the same temperature and pressure will have equal number of molecules.
Hence, according to Avogadro's law, the two gases will have equal number of molecules.
