Looking for evidence entails careful study. The answers to the question is below;

<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.

How many grams of nh3 can be produced from 4.08 mol of n2 and excess h2. express your answer numerically in grams?

Lunna [17]

The reaction of N2 and H2 to generate NH3 is as follows:N2 + 3H2 ⇒2NH3

Since H2 is in excess amount in this reaction, the determine factor is N2. The ratio of N2 and product NH3 is 1:2. Therefore, 4.08 moles of N2 can generate 4.08*2 = 8.16 mole of NH3.

Grams of NH3 = moles of NH3 * molar mass of NH3 = 8.16 mole * 17 g/mole = 139 g.

139 grams of nh3 can be produced from 4.08 mol of n2 and excess h2.

A catalyst lowers the activation energy for both the forward and the reverse reactions in an equilibrium system, so it has no ef

rosijanka [135]

Answer:

True.

Explanation:

Catalyst increases the rate of the reaction without affecting the equilibrium position.

Catalyst increases the rate via lowering the activation energy of the reaction.

This can occur via passing the reaction in alternative pathway (changing the mechanism).

The activation energy is the difference in potential energies between the reactants and transition state (for the forward reaction) and it is the difference in potential energies between the products and transition state (for the reverse reaction).

in the presence of a catalyst, the activation energy is lowered by lowering the energy of the transition state, which is the rate-determining step, catalysts reduce the required energy of activation to allow a reaction to proceed and, in the case of a reversible reaction, reach equilibrium more rapidly.

with adding a catalyst, both the forward and reverse reaction rates will speed up equally, which allowing the system to reach equilibrium faster.

What happens when you combine Bleach And Ammonia?<br> best answer will get brainly

Nataliya [291]

Answer:

It can be very dangerous and possibly deadly to mix bleach and ammonia.

Explanation:

When you combine these two household cleaners they release toxic chloramine gas. If you are exposed to chloramine gas it may cause irritation in your eyes, nose, throat, and lungs. It can even lead to coma and death in higher concentrations.

when 45 grams of copper (ii) carbonate are decomposed with heat how many grams of carbon dioxide will be produced

Maksim231197 [3]

Answer:

16.02 g

Explanation:

the balanced equation for the decomposition of CuCO₃ is as follows

CuCO₃ --> CuO + CO₂

molar ratio of CuCO₃ to CO₂ is 1:1

number of CuCO₃ moles decomposed - 45 g / 123.5 g/mol = 0.364 mol

according to the molar ratio

1 mol of CuCO₃ decomposes to form 1 mol of CO₂

therefore 0.364 mol of CuCO₃ decomposes to form 0.364 mol of CO₂

number of CO₂ moles produced - 0.364 mol

therefore mass of CO₂ produced - 0.364 mol x 44 g/mol = 16.02 g

16.02 g of CO₂ produced
