Answer:
Density
Explanation:
The density of an irregularly shaped object can be obtained by weighing it and then drooped int a graduated cylinder; observing the change in volume.
The density is the calculated as;
Density = Mass / Change in volume
where;
Change in volume = Final Volume - Initial Volume
Answer:
Because we need to dispense 4.7 mL, the volume reading in the pipet is the 5.3 mL line.
Explanation:
First we use C₁V₁=C₂V₂ in order to <u>calculate the required volume of concentrated HCl</u> (V₁):
12.85 M * V₁ = 0.600 M * 100 mL
V₁ = 4.7 mL
<u>So we need to dispense 4.7 mL of the concentrated HCl solution</u>. The mark in the pipet that would contain that volume would be 10.0 - 4.7 = 5.3 mL
Since water consists of hydrogen and oxygen, you would need to "disintegrate" it into its smaller parts. This means that in order to create hydrogen and oxygen from water, you would need to perform B. decomposition.
Well, you would need to know how to properly name these chemical compounds and elemental compounds, specifically ionic compounds.
1. H2 + I2 -> 2HI - Synthesis
2. 2Li + 2HCl -> 2LiCl + H2 - SR - Single replacement
3. Na2CO3 -> Na2O + CO2 - Decomposition
4. 2HgO -> 2Hg + O2 - Decomposition
5. Mg(OH)2 -> MgO + H2O - Decomposition
6. Cu + Cl2 -> CuCl2 - Synthesis
7. Ca(ClO3)2 -> CaCl2 + 3O2 - Decomposition.
8. 2Li + 2H2O -> 2LiOH + H2 - Single Replacement Reaction.
