Answer:
<h2>Density = 3.9 g/ mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 43 g
volume = 11.1 mL
Substitute the values into the above formula and solve for the density
That's
We have the final answer as
Density = 3.9 g/ mL to one decimal place
Hope this helps you
Lithium - Malleable, soft, and shiny
Lead - Opaque solid with higher density
Fluorine - Highly reactive gas
Krypton - Nonreactive gas

There are actually three: One oxygen atom and two hydrogen atoms.
<h3>
Answer:</h3>
Electrolytes: NaBr, H3PO4, NaOH and NH3
Non-electrolyte: C6H12O6
<h3>
Explanation:</h3>
- An electrolyte is a good conductor of electric current while non electrolyte are poor conductors of electric current.
- Electrolytes conduct while in aqueous or molten form and can be decomposed by passing electric current through them.
- Electrolytes conduct electric current due to the presence of mobile ions.
- Non-electrolytes do not ionize while in aqueous form and thus do not conduct electric current.
- Examples of electrolytes in this case are, NaBr, H3PO4, NaOH and NH3
- Examples of Non-electrolytes in this case are C6H12O6
Answer:
to form a metamorphic rock, rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which transforms the existing rock into a new type of rock, changing the minerals’ composition in the process. Any of these three factors, or a combination of them, can lead to a metamorphic rock being formed.
