A business that is owned and run by one person is a sole proprietorship.
Answer:
quartz (SiO2)n
Explanation:
Melting point is defined as the temperature or point at which the substances change its state from solid to liquid.
Quartz (SiO2)n has high melting point than O2 because Quartz (SiO2)n is found in the form of hard, crystalline mineral that is made up of silicon and oxygen atoms having strong covalent bonds between all the atoms. So, a lot of energy is required to break the bond between the atoms and it has a high melting point.
Hence, the correct answer is quartz (SiO2)n.
If anything you would use a protractor but that’s not a answer.... so I would pick whatever relates to a protractor
N₂H₄ :
N = - 2
H = + 1
2 * ( -2 ) + ( 1 * 4 ) = - 4 + 4 = 0
hope this helps!
Answer:
Na⁺ (aq) + OH⁺ (aq) + H⁺ (aq) + Cl⁻ (aq) → Na⁺ (aq) + Cl⁻ (aq) + H₂O (l)
General Formulas and Concepts:
<u>Atomic Structure</u>
<u>Aqueous Solutions</u>
- Solubility Rules
- States of matter
<u>Stoichiometry</u>
- Reaction RxN Prediction
- Balancing Reactions RxN
Explanation:
<u>Step 1: Define</u>
NaOH reacting w/ HCl
NaOH is soluble
HCl is soluble
[RxN] NaOH (aq) + HCl (aq) → NaCl (aq) + H₂O (l)
<u>Step 2: Total Ionic Equation</u>
<em>Break up soluble compounds into ionic form.</em>
[T.I.E] Na⁺ (aq) + OH⁺ (aq) + H⁺ (aq) + Cl⁻ (aq) → Na⁺ (aq) + Cl⁻ (aq) + H₂O (l)
