Please help! If a forensic chemist discovers evidence through examination which would prove a person guilty of a crime, why then might this person not be convicted?

Answers

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.

Answer:

The release of energy with the fusion of light elements is due to the interplay of two opposing forces: the nuclear force, which combines together protons and neutrons, and the Coulomb force, which causes protons to repel each other.

which element has the lowest atomic mass?

Answers

Answer:

Hydrogen

Explanation:

Hydrogen has only 1 proton and has an atomic mass of 1. It does not have neutrons. Helium and above have higher mass than Hydrogen.

According to the electronic configuration, element with lowest atomic mass is hydrogen.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

How long will a 25.00 g
sample of americium-241
toke to decay to form a 6.25
g sample of americium-241?

Answers

Answer:

Hope it helps.

Explanation:

It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131

Heavy unstable atoms will continuously emit radiation and will undergo nuclear decay to form stable products. 25 g of americium -241 will take 39 years to decay into its 6.25 g sample.

What is radioactive decay?

Heavy unstable nuclei undergo decay when they emit radiations of alpha, beta or gamma particles. After that they will form stable isotopes or other lighter nuclei after emitting these charged particles.

The time an unstable nuclei takes to decay into half of its initial amount is called half life time. The half life time of Americium -241 is 432 years. Thus half life time of 25 g of Am-241 is

= (25 × 432 )/241

= 44.81 years.

The decay constant k can be calculated as follows:

k = 0.693 /half life time

  = 0.693 /44.81 yrs

 = 0.015.

Now the time taken for the decay process is calculated by the following  equation:

t = 1/k log (25/6.25)

 = 1/0.015yr-1  log (25/6.25)

 = 39 years

Hence, 5 g of americium -241 will take 39 years to decay into its 6.25 g sample.

First we have to convert the kilometers to grams;

1 kilometer = 1,000 meters

This means we have;

55000 meters per hour

Converting hour to seconds;

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60 * 60 = 3600 seconds

We divide 55000 by 3600;

The mercury atoms in the plasma generate light very efficiently, but much of it is ultra-violet (UV), invisible to the eye and harmful to it (or rather, it would be, were it not absorbed by the glass).

The solution is to coat the inside of the tube with a glow-in-the-dark (fluorescent) paint, which absorbs the UV and re-emits its energy as visible light.

Identify the substance oxidized and the substance reduced in the following chemical equation:zn(s)+AgNO3(aq)=Zn(No3)2+2Ag(a)​

Answers

Answer:

Explanation:

zn is oxidized because its oxidation number is increased from zero in zn to +2 in zn(No3)2

Ag is reduced because its oxidation number is reduced from +1 in AgNo3 to zero in Ag

oxidation number of zn(s) is zero while the oxidation number of zn in zn(No3)2  is

zn(No3)2=x+(5*2)+(-2*6)=x+10-12=x-2

x-2+2=2

x=2

the oxidation of Ag in AgNo3

AgNo3=x+5+(3*-2)=x+5-6=x-1

x-1+1=1

x=1 while the oxidation number of Ag is zero

so zinc is oxidized and silver (Ag) is reduced

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) Round to the nearest Whole Number.

Answers

Answer:

The six-row combin harvests 285 bushels of corn per hour.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, you can apply the following formula:

a ⇒ b

c ⇒ x

So: [tex]x=\frac{a*b}{c}[/tex]

In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?

[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]

x=4.75

This is, a six row combin harvests 4.75 bushels of corn per min.

So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?

[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]

bushels of corn=  285

The six-row combin harvests 285 bushels of corn per hour.

2. What was the primary reason in the 1850's driving the curiosity of atoms?
1905-Einstein
1827-Brown

Answers

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.
