Answer:

Explanation:

I can't see the supposed chemical equations, but I'm guessing it's like every other chemical equations.

Now, the 2 added to the front of HCl is just to balance the chemical equation. It is specifying the amount of moles of HCl that is used in the particular reaction.

Essentially, the chemical equation is saying that 2 moles of HCl is reacting with however many moles of the other reactant to give the product you're seeing.

ValentinkaMS [17]

1)They are very reliable because they are almost always accurate.All science in the courtroom has to be verified in order to be used in the court to prove that their tests are accurate and reliable and can be used as an evidence in court. Reliability is measured by how much your machines have been validated ,if a forensic scientist in a court say the evidence is true but did not have a proper reliability , than people can question how true this test can actually be. Hard science is consisted of chemistry,biology and physics are the most reliable evidence.

2)The reliability of the analytical science in the courtroom is growing. This is because of the fact that analytical science involves comparison between the characteristics and features of the suspected specimens with those obtained from the criminals or victims.

On Monday, Travis took his four-wheeler to Reppart's Equipment & Service for repair because the steering was not working pro
kumpel [21]

Answer:

The service repair company advised Travis of the issues with the steering problems.  He disregarded the notice and decided to drive the four wheeler before fixing the issue.  Therefore, Travis assumed all responsibility after knowingly driving the four wheeler after being told of its issues.  The people who he hit and caused damaged or injury to would clearly  have a case against him.  Perhaps even if he wasn't aware of the problems and caused damage to their persons or property, he would still be at fault. However, in that situation, he would likely be able to go after the service repair shop showing negligence on their part for failure to disclose this information.
