Answer:
The density of the metal is 0.561 g/mL
Explanation:
The computation of the density of the metal is shown below;
As we know that
The Density of the metal is
where,
Mass = 4.9g
Change in volume = 6.9 mL
Now place these values to the above formula
So, the density of the metal is
= 0.561 g/mL
Hence, the density of the metal is 0.561 g/mL
We simply applied the above formula so that the correct density could arrive
A should be the answer because the more you test an experiment the more data you have to rely on changing the experiment would cause you to have different outcomes making the results different and unreliable so B, C, and D is not going to be the answer Hope this helps
2 H₂ + O₂ → 2 H₂O
Al₂O₃ + 6 HCl → 2 AlCl₃ + 3 H₂O
CH₄ + 2 O₂ → CO₂ + 2 H₂O
Explanation:
To balance the chemical equations the number and type of atoms entering the reaction have to be equal to the number an type of atoms leaving the reactions. To do this we add coefficients (usually integer numbers) before each substance.
So we have the following balanced chemical reactions:
2 H₂ + O₂ → 2 H₂O
Al₂O₃ + 6 HCl → 2 AlCl₃ + 3 H₂O
CH₄ + 2 O₂ → CO₂ + 2 H₂O

Hydrocarbons that lack π bond are called saturated hydrocarbons or alkanes
<h3>Hydrocarbons</h3>
- Hydrocarbon is an organic compound consisting of hydrogen and carbon.
- Hydrocarbons is an examples of 14 group hydrides.
- Hydrocarbons are colorless and hydrophobic.
- Their odors are usually like gasoline or lighter fluid.
- In oil and gas industry, the hydrocarbon in term, combines petroleum and natural gas they are the two naturally occurring phases of hydrocarbon.
<h3>Alkanes</h3>
- Alkanes also konwn as parafins
- They are called as saturated hydrocarbons
- Alkanes contain hydrogen and carbons arranged in tree structure
- Alkanes have two main sources petroleum and natural gas.
Therefore, Hydrocarbons that lack π bond are called saturated hydrocarbons
