Answer: molecules of
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mole of contains = molecules
0.128 mole of contains = molecules
Thus there are molecules of
Answer:
1. How many electrons does hydrogen need in order to have a full shell of valence electrons?...two
2. How do valence electrons impact the type of bonds an atom makes?...An atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs.
3.Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use “–” to represent a single bond and “=” to represent a double bond.)...O=C=O
4. Methane’s chemical formula is CH4. Is there a bond between any of the hydrogen atoms? Why or why not?...No, there is not because carbon needs four bonds, so it bonds with each hydrogen atom; hydrogen only forms one bond.
5. In hydrogen peroxide (H2O2), which option best shows how the atoms are ordered?...H-O-O-H

<h2>Answer:</h2>
<em>Given data:</em>
1 kilogram = 1,000 grams
How many kilograms 1,830 grams?
<em>Solution:</em>
1000 grams = 1 kilogram
1 gram = 1/1000 kilograms
1,830 grams = 1/1000 * 1830 = 1.830 kilogram
<em> Hence 1,830 grams = 1.830 kilogram</em>
