What is depicted as the yellow arrows in the following image? (Using a scientific vocabulary word we learned in class and provide its definition) Which makes a bigger current- faster moving electrons or slower moving electrons?
Answers
Answer:
Electric Current
Explanation:
The yellow arrows in the following image depict electric current. Electric current is defined as the continuous flow of electrons in an electric circuit. Electrons present in the conducting material which move from one to another atom randomly from the negative terminal through the connecting wires and back to the positive terminal.
Faster moving electrons make a bigger current because faster moving electrons collide more with each other that generates more heat which results into a higher current.
Hence, The yellow arrows in the following image depict electric current and Faster moving electrons make a bigger current.
The yellow arrow in the diagram shows the flow of electrons.
Current is defined as the flow of electrons in a circuit. The yellow arrows represents the direction of the flow of electrons in the circuit. The battery provides the potential difference that drives the flow of electrons through the wire.
Since current has to do with the movement of electrons in a circuit, the faster the movement of the electrons, the bigger the current.

If you have 2.0 moles of sodium chloride (NaCl), what is its mass in grams?
Answers
Answer:
117g
Explanation:
Given parameters:
Number of moles = 2moles
Unknown:
Mass of NaCl = ?
Solution:
To solve the problem, we need to use the expression below;
Mass of NaCl = number of moles x molar mass
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
So;
Insert the parameters and solve;
Mass of NaCl = 2 x 58.5 = 117g

0.45 g of hydrated sodium carbonate crystals were heated until 3.87 of anhydrous power remained.
How many moles of water are there in one mole of hydrated salt?
Answers
Formula of hydrated sodium carbonate : Na₂CO₃.10H₂O, so moles of water in one mole of hydrated salt = 10
Further explanationHydrate is a compound that binds water (H₂O), usually in the form of crystals/ solids
If these compounds are dissolved in water or heated, the hydrates can decompose:
Example: X.YH₂O (s) → X (aq) + YH₂O (l)
The formula for the hydrated compound contains: YH2O
The mole ratio shows the ratio of the coefficients of the hydrate compound
10.45 hydrated sodium carbonate(Na₂CO₃.xH₂O) were heated until 3.87 of 3.87of anhydrous (Na₂CO₃) remained, so
mass H₂O released :
[tex]\tt 10.45-3.87=6.58~g[/tex]
mass Na₂CO₃ = 3.87 g
mol ratio Na₂CO₃(MW= g/mol) : H₂O(MW=18 g/mol) =
[tex]\tt \dfrac{3.87}{105,9888}\div \dfrac{6.58}{18}=0.0365\div 0.3655=1\div 10[/tex]
1. Kaleigh notices when she goes to the beach that sometimes the water rises as high as the pier. At other times of the day, the water barely covers the pillars under the pier. These differences in water level are primarily due to the gravitational influence of which of the following?
a. The Earth’s revolution b. The Moon c. asteroids d. comets
Answers
Tides are due to the gravitational forces of the Moon and the Sun. The tide is high when the moon or the sun or both are on the side of the sea and vice versa.
The effect of tides due to the moon is much greater than that of the sun, because the moon is much closer to the earth.

When temperture changes matter undergo this. that is shift one form to another
Answers
Answer:All matter can move from one state to another. It may require extreme temperatures or extreme pressures, but it can be done. Sometimes a substance doesn't want to change states. You have to use all of your tricks when that happens. To create a solid, you might have to decrease the temperature by a huge amount and then add pressure. For example, oxygen (O2) will solidify at -361.8 degrees Fahrenheit (-218.8 degrees Celsius) at standard pressure. However, it will freeze at warmer temperatures when the pressure is increased.
Some of you know about liquid nitrogen (N2). It is nitrogen from the atmosphere in a liquid form and it has to be super cold to stay a liquid. What if you wanted to turn it into a solid but couldn't make it cold enough to solidify? You could increase the pressure in a sealed chamber. Eventually you would reach a point where the liquid became a solid. If you have liquid water (H2O) at room temperature and you wanted water vapor (gas), you could use a combination of high temperatures or low pressures to solve your problem.
Points of Change
Phase Changes: Pressure and temperature define the state of matter for water.Phase changes happen when you reach certain special points. Sometimes a liquid wants to become a solid. Scientists use something called a freezing point or melting point to measure the temperature at which a liquid turns into a solid. There are physical effects that can change the melting point. Pressure is one of those effects. When the pressure surrounding a substance increases, the freezing point and other special points also go up. It is easier to keep things solid when they are under greater pressure.
Generally, solids are more dense than liquids because their molecules are closer together. The freezing process compacts the molecules into a smaller space.
There are always exceptions in science. Water is special on many levels. It has more space between its molecules when it is frozen. The molecules organize in a specific arrangement that takes up more space than when they are all loosey-goosey in the liquid state. Because the same number of molecules take up more space, solid water is less dense than liquid water. There are many other types of molecular organizations in solid water than we can talk about here.

A group of tourists were on an outing when they noticed that precipitation began to fall. The air temperature was 32 degree Fahrenheit. What type of precipitation did they most likely see?
Answers
Answer:
The correct answer is - rain.
Explanation:
At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.
At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.
Thus, the precipitation is in the form of rain.

0 kgm/s
12.5 kgm/s^2
Answers
Answer:
0 kgm/s
Explanation:
The momentum of Bob while resting at the river is 0 kgm/s.
This is because the momentum of any object at rest is 0.
Momentum is the quantity of motion a body contains. It is mathematically expressed as;
Momentum = m x v
m is the mass
v is the velocity
So at rest, the velocity of a body is 0m/s and therefore, the momentum is O

A tank containing oxygen, carbon dioxide, and nitrogen gases has a total pressure of 6.7
atm. If the O2 has a pressure of 3.0 atm and the carbon dioxide has a pressure of 1.2
what is the partial pressure of the nitrogen gas?
Answers
Answer:
P(N₂) = 2.5 atm
Explanation:
Given data:
Total pressure of gasses = 6.7 atm
Partial pressure of O₂ = 3.0 atm
Partial pressure of CO₂ = 1.2 atm
Partial pressure of N₂ = ?
Solution;
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(O₂) + P(CO₂) + P(N₂)
6.7 atm = 3.0 atm + 1.2 atm + P(N₂)
6.7 atm = 4.2 atm + P(N₂)
P(N₂) = 6.7 atm - 4.2 atm
P(N₂) = 2.5 atm
