Don't use the brakes too hard when u stop. That can cause the biker to fall forward.
Give me a thanks if it helps!!
Answer:
The unknown metal could be calcium or magnesium.
Explanation:
Displacement of a metal from its chemical reaction is shown by the reaction known as single displacement reaction. The reactivity of metal is determined by the reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the reactivity series.
Metal B is more reactive than metal A.
The metal which easily displaced aluminium will lie above in the series but that same element cannot displace sodium, so it will lie below in the series.
Hence, from the series, we conclude that the unknown metal could be calcium or magnesium.

<h3>Evidence and Fact finding</h3>
The crime that Mr. Fraser describes is drive-by killing.
The police select their suspect by the act of showing pictures to one of the teenagers and thereafter they the suspect out, the suspect the saw that shoot the father.
The fact was that there was no evidence since they did not find the gun and the car used in the crime was not identified. Even the suspect vehicle (shooter) was not identified also.
The approximate figure is about 252 out of 367 cases of wrongful conviction have been identified. That is 69% of DNA exonerations. Others about 250-285 cases.
The National Registry of Exonerations has stated that about 450 non-DNA-based exonerations where there was eyewitness misidentification. That is about 3 quarters have eye witness testimonies.
Reconstructive memory is simply known as the act of remembering that involves the reproduction of an experience or event that is known to be partially stored in memory before.
Fraser challenged the judge to go out and inspect the crime scene themselves.
The outcome of the challenge was that the judge thereby granted the retrial for Francisco Carrillo and thus released him so he can prepare his defense before the prosecution day.
Mr. Fraser suggested that people learn to be more effective with how they handle things or situations so as to get the right evidence and also that people be more cautious about how true some eyewitness testimonies may be.

Explanation:
Hello, let's observe the given data first. The data says The conc of magnesium chloride solution is 0.117 mol/L that means in one litre solution 0.117 mole MgCl2 are present. but we have to find the moles of magnesium chloride, magnesium ions & chloride ions in 16.4 mL solution.
Now 16.4 ml solution contains 1.91× 10-³ magnesium chloride.
Before finding the amount of ions in solution let's have a look at dissociation of magnesium chloride.
<em>One mole of Magnesium chloride produces 1 mole of magnesium & 2 mole of chloride ions.</em>
Hence 1.91× 10-³ moles of magnesium chloride will produce 1.91 × 10-³ moles of magnesium ion & 3.82 × 10-³ moles of chloride ions.
