Why are poisons used less today than they were in the past? What factors influenced this change.
Answer:
Poisons are used less today than they were in the past because forensic scientists can easily detect many substances and toxins during an autopsy.
The main factor that influenced this change is advancements in forensic toxicology knowledge and technology.
good luck, i hope this helps :)
Explanation:
Today poisons are used less because forensic scientists now have much more equipment and have an easier time at identifying poisons like arsenic, which were not so easy to find in the past. The main factor influencing this change is the new technology and knowledge that was unavailable in the past.

Explain why hydrocarbons are present in so many different compounds.
Answer:
Many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. We use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil.
What two physical properties depend on the sample size of a substance? Give examples for
each.
Answer:
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present.

What is the source of substances that are not natural resources
Answer:
A nonrenewable resource is a substance that is being used up more quickly than it can replace itself. Its supply is finite. Most fossil fuels, minerals, and metal ores are nonrenewable resources. Renewable resources such as solar and wind power and water are unlimited in supply.

How many moles are in a 4.5g of Sulfur?
Answer:
~0.14
Explanation:
There are roughly ~0.14 moles in 4.5g of Sulfur. 1 mol = 32.06 g of Sulfur, so we just find the ratio and then multiply.
Answer:
[tex]\boxed {\boxed {\sf About \ 0.14 \ mol \ S }}[/tex]
Explanation:
To convert from grams to moles we must use the molar mass. This can be found on the Periodic Table.
Sulfur (S); 32.07 g/molWe can use this number as a ratio or fraction.
[tex]\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]
Multiply by the given number of grams: 4.5
[tex]4.5 \ g \ S *\frac{ 32.07 \ g \ S }{1 \ mol \ S }[/tex]
Flip the fraction so the grams of sulfur cancel.
[tex]4.5 \ g \ S *\frac{1 \ mol \ S }{32.07 \ g \ S}[/tex]
[tex]4.5 *\frac{1 \ mol \ S }{32.07 }[/tex]
[tex]\frac{4.5 \ mol \ S }{32.07 }[/tex]
[tex]0.140318054 \ mol \ S[/tex]
The original measurement of grams had 2 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place.
The 0 in the thousandth place tells us to leave the 4.
[tex]0.14 \ mol \ S[/tex]
There is about 0.14 moles of sulfur in 4.5 grams.
When kci dissolved in ethanol what is the intermolecular attraction between k+ ions and ethanol molecules
Answer:
ion-dipole interaction
Explanation:
Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.
The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.
When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.

Calculate the molarity for a solution containing 0.34 moles of NaNO3 dissolved in 0.5 liter of
water.
Answer:
0.68 mol/L
Explanation:
M=m/l
m is moles and l is liters
Since they gave us the values in the correct units, all we have to do it plug it in
M=0.34 mol/0.5 liters
M=0.68
A gas at 127 celsius and 10.0 L expands to 20.0 L. What is the new
temperature in kelvin? (You must convert to Kelvin before calculating
this problem
Answer:
T₂ = 800 K
Explanation:
Given that,
Initial temperature of the gas, T₁ = 127°C = 400 K
Initial volume, V₁ = 10 L
Final volume, V₂ = 20 L
We need to find the new temperature.
The volume of a gas is directly proportional to its Kelvin temperature.
Let T₂ is the new temperature. So,
[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K[/tex]
So, the new temperature of the gas is 800 K.

What is the molecular formula for C5H7 if its molar mass is 536 g/mol?
Answer:
(C5H7)8
Explanation:
It's empirical formula is given as; C5H7
Molar mass of carbon(C) = 12 g/mol
Molar mass of hydrogen(H) = 1 g/mol
We are told that it's molar mass is 536 g/mol.
To find the molecular formula;
Molecular formula = n × empirical formula
Thus;
n = 536/((12 × 5) + (1 × 7))
n = 8
Thus;
Molecular formula = (C5H7)8
The products of a neutralization reaction are an acid and a base. (i need to rewrite the statement and make it true.)
Explanation:
neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form water.
In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

if there is 4 protons, 2 electrons, 5 neutrons what is the iconic charge and what element is this ?
Answer:
Be^2+
Explanation:
The atomic number indicates the number of protons so the element is Be (beryllium)
So now we know that a neutral atom contains four electrons but there are 2 so that means two electrons were taken away, making it positive. It would be a 2+ charge.
