What is the molarity of a solution made by diluting 0.025L of 6.0 M HCl until
the final volume of the solution is 1.75 L?
Answer:
Explanation:
Use the dilution equation: M1V1 = M2V2
M1 = 6.0 M
V1 = 0.025 L
M2 = ?
V2 = 1.75 L
(6.0 M)(0.025 L) = M2(1.75 L)
Solve for M2 --> M2 = 0.086 M HCl
1. The chemical formula of caffeine is C8H10N4O2. Determine the percent composition of the molecule.
Show work please
Answer:
we find the mass for each element in one mole by multiplying the number of atoms in one molecule with the atomic mass
mC=8Ac=8*12=96g
mH=10AH=10*1=10g
mN=4AN=4*14=56g
mO=2AO=2*16=32g
by adding the masses together we find the molar mass of the molecule
M=mC+nH+mN+mO=96+10+56+32=194g/mole
we apply the rule of threes to find the percentage of each element
194g..96gC..10gH...56gN....32gO
100g....a...........b...........c.............d
a=(100*96)/194=49.48%C
b=(100*10)/194=5.19%H
c=(100*56)/194=28.85%N
d=(100*32)/194=16.48%O

You take a gas at 3 atm and increase the temperature from 120 K to 240 K. What is the final pressure?
A
6 atm
B
Not enough information
C
3 atm
D
1.5 atm
Answer:
A. 6atm
Explanation:
Using pressure law equation:
P1/T1 = P2/T2
Where;
P1 = initial pressure (atm)
T1 = initial temperature (K)
P2 = final pressure (atm)
T2 = final temperature (K)
According to this question;
P1 = 3 atm
P2 = ?
T1 = 120K
T2 = 240K
Using P1/T1 = P2/T2
3/120 = P2/240
Cross multiply
240 × 3 = P2 × 120
720 = 120P2
P2 = 720/120
P2 = 6atm
Is temperature and pressure directly proportional or inversely proportional?
A. Inversely proportional
B. Directly proportional

What happened during the fusion reaction shown?
Answer:
the answer to this question B. Two H nuclei that fused into one He necleus
Explanation:
Two hydrogen atoms fused to one helium molecule, hence option B is correct.
What is fusion?Fusion is defined as a process in which two or more atomic nuclei unite to create new atomic and subatomic particles. Heat, which is produced when two atoms fuse, is the key to generating energy. Similar to how nuclear fission produces energy, this heat can be utilized to warm water, produce steam, and turn turbines to produce electricity.
In the core of the Sun, hydrogen is being converted to helium. This phenomenon is known as nuclear fusion. Fusion is what powers both the sun and the stars. One example of this kind of reaction is when two hydrogen atoms combine to form a helium atom. During the process, a portion of the hydrogen's mass is converted into energy.
Thus, two hydrogen atoms fused to one helium molecule, hence option B is correct.

determine the velocity of a cart traveling at 135cm in 5.5s.
Answer: 0.245 m/s
Explanation:
So velocity = d/t or distance over time in this case m/s or meters per second. But BE CAREFUL you must remember to convert cm to m always so 135 cm= 1.35m and 1.35m/5.5s= 0.245m/s
Gas in a balloon occupies 3.3 liters. What volume will it occupy if the pressure is changed from 100 kPa to 90.0 kPa, if the temperature is held constant?
Answer:
3.7 L
Explanation:
Initial volume (V₁) = 3.3 L
Initial pressure (P₁) = 100 KPa
Final pressure (P₂) = 90 KPa
Final volume (V₂) =?
The final volume of the gas can be obtained by using the Boyle's law equation as follow:
P₁V₁ = P₂V₂
100 × 3.3 = 90 × V₂
330 = 90 × V₂
Divide both side by 90
V₂ = 330 / 90
V₂ = 3.7 L
Thus, the final volume of the gas is 3.7 L

Why does a DNA fingerprint require millions of copies of each DNA fragment
Answer:
Because it can identify a person.
A DNA fingerprint is a piece of DNA so distinct that it can prove a person's identity. These distinct areas can take on many different forms, but each form is unique to any one individual.
PCR allows the amplification of a single copy of DNA into millions of copies. However this technique requires that the DNA of interest already be of a known sequence in order to design primers that will specifically hybridize to the target DNA.
It is important as:
It's used as evidence in courts, to identify bodies, track down blood relatives, and to look for cures for disease.

What are resistors? please help
Answer:Resistor Basics
Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit.
They are passive components, meaning they only consume power (and can't generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines.
Resistor units
The electrical resistance of a resistor is measured in ohms. The symbol for an ohm is the greek capital-omega: Ω. The (somewhat roundabout) definition of 1Ω is the resistance between two points where 1 volt (1V) of applied potential energy will push 1 ampere (1A) of current.
As SI units go, larger or smaller values of ohms can be matched with a prefix like kilo-, mega-, or giga-, to make large values easier to read. It's very common to see resistors in the kilohm (kΩ) and megaohm (MΩ) range (much less common to see miliohm (mΩ) resistors). For example, a 4,700Ω resistor is equivalent to a 4.7kΩ resistor, and a 5,600,000Ω resistor can be written as 5,600kΩ or (more commonly as) 5.6MΩ.
Schematic symbol
All resistors have two terminals, one connection on each end of the resistor. When modeled on a schematic, a resistor will show up as one of these two symbols:
Resistor schematic symbols
Two common resistor schematic symbols. R1 is an American-style 1kΩ resistor, and R2 is an international-style 47kΩ resistor.
The terminals of the resistor are each of the lines extending from the squiggle (or rectangle). Those are what connect to the rest of the circuit.
The resistor circuit symbols are usually enhanced with both a resistance value and a name. The value, displayed in ohms, is obviously critical for both evaluating and actually constructing the circuit. The name of the resistor is usually an R preceding a number. Each resistor in a circuit should have a unique name/number. For example, here's a few resistors in action on a 555 timer circuit:
Answer: resistor is
Explanation:
A resistor controls the flow of the electrical current within a circuit. Resistors are made from materials like copper or carbon, which make it difficult for the electrical charges to flow through a circuit. The most common type of resistor is a carbon resistor, which is a general purpose resistor, best suited for lower-powered circuits.
