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.
A child drops a ball from a bridge. The ball strikes the water under the bridge 2.0s later. What is the velocity of the ball when it hits the water
Answer:
20m/s
Explanation:
Given that :
Time, t = 2 seconds
Using the relation :
v = u + at
a = g is positive (downward)
V = final velocity
u = initial velocity = 0
v = u + gt
v = 0 + 10(2)
v = 20 m/s

1.) List the actual volume of titrant needed to produce a color change for Sample A and Sample B. Answer:
Volume of titrant needed to produce a color change for Sample A: ___ ml Volume of titrant needed to produce a color change for Sample B: ___ ml
2.) There are many aspects to the technique known as titration that are extremely important if results are to be accurate. In a traditional or authentic laboratory setting, these techniques are important and sometimes delicate. List two of the techniques used in this lab that provided you will the most accurate possible results. Describe why these techniques are important and how ignoring the techniques would affect the lab.
Answer:
Technique #1: …
Why technique is important: …
Technique #2: …
Why technique #2 is important: …
3.) The titration procedure you have just performed is similar to what is carried out by water-quality workers throughout the world. They use a kit to perform titration on location instead of in a laboratory. In real-life situations, workers collect water samples in a lake or stream. In lakes and streams calcium carbonate (CaCO3) causes alkalinity. Calcium carbonate acts as a buffer, a substance that serves to resist small changes in acidity or alkalinity in a solution. When acid rain enters lake water, it can be neutralized by the bases present and thus the lake does not become too acidic. Since the key ion is the hydroxide ion, the nature of the location doesn’t matter in this case. All over the world, right now, pollution workers are measuring calcium carbonate in lakes and streams.
If a worker studied two lakes and Lake X had a greater ppm (concentration in parts per million) of calcium carbonate than Lake Z, and both lakes are the exact same size, which of the two lakes would be able to withstand a greater amount of rain that is acidic? Explain your answer.

For the balanced equation shown below, how many moles of N2 will react with 0.3034 moles of Mg?
3 Mg + N2 Mg3N2
Round answer to 4 sig-figs.
Answer:
0.1011 moles of N₂
Explanation:
This is the reaction:
3 Mg + N₂ → Mg₃N₂
3 moles of magnesium can react to 1 mol of nitrogen in order to produce 1 mol of magnesium nitride.
We can solve this by a rule of three:
3 mol of Mg need 1 mol of N₂ for the reaction
Then, 0.3034 moles of Mg may react to (0.3034 . 1) / 3 = 0.1011 moles of nitrogen.

Which two statements describe what happens to the nuclei of atoms during a fusion reaction? O A. Large nuclei break apart into two or more smaller nuclei. O B. A small amount of mass in the nuclei that combine is converted to energy. O c. Each nucleus formed has fewer protons than each original nucleus had. O D. Nuclei with small masses combine to form nuclei with larger masses.
Answer:
D. Nuclei with small masses combine to form nuclei with larger masses.
B. A small amount of mass in the nuclei that combine is converted to energy
Explanation:
A nuclear fusion, in contrary to fission, is the process by which the nuclei of two atoms combine to form a much larger atom with a large nuclei. Likewise, during a fusion reaction, a large amount of energy is released from the small amount of mass in the nuclei (two) that combines.
According to this question, the following are true of a fusion reaction:
- Nuclei with small masses combine to form nuclei with larger masses.
- A small amount of mass in the nuclei that combine is converted to enormous energy.

In part A, when you added water to the sodium acetate in the flask, some of the chemical dissolved into the water. Would you call this solution unsaturated, saturated, or supersaturated? Give reasons for your answer.
Answer: The solution is a SATURATED solution.
Explanation:
Although most substances are soluble in water, some are more soluble than others,that is , their solubilities differ. SOLUBILITY is a means of comparing the extent to which different solutes can dissolve in a particular solvent at a definite temperature.
From the question above, when water was added to the sodium acetate in the flask, SOME of the chemical dissolved into the water, meaning that some remained undissolved. This is because a given volume of water can only dissolve a certain amount of chemical in it at room temperature. If more chemical is added to such a solution, the chemical will remain undissolved. Such a chemical solution is said to be a SATURATED SOLUTION.
A saturated solution of a solute at a particular temperature is on which contains as much solute as it can dissolve at that temperature in the presence of undissolved solute particles.
Unsaturated solution is a type of solution that dissolves all its solutes with no presence of undissolved solute.
Supersaturated solution is one which contains more of the solute than it can normally hold at that temperature. It is an unstable solution which crystallizes out when disturbed.

The percentage composition of acetic acid is found to be 39.9% C, 6.7% H, and 53.4% O. What is the empirical formula of acetic acid?
Answer:
CH₂O
Explanation:
From the question given above, the following data were obtained:
Carbon (C) = 39.9%
Hydrogen (H) = 6.7%
Oxygen (O) = 53.4%
Empirical formula =?
The empirical formula of acetic acid can be obtained as follow:
C = 39.9%
H = 6.7%
O = 53.4%
Divide by their molar mass
C = 39.9 / 12 = 3.3
H = 6.7 / 1 = 6.7
O = 53.4 / 16 = 3.3
Divide by the smallest
C = 3.3 / 3.3 = 1
H = 6.7 / 3.3 = 2
O = 3.3 / 3.3 = 1
The empirical formula => CH₂O
