Both “blank” and “ blank” use electric current and coiled wires to produce strong magnetic fields.
Answer:
electromagnet
Explanation:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil.

which arrow represents water forming outside a cold water bottle left outside
Answer:
The phase transition that represent the the cooling of gaseous water to form liquid outside a bottle left outside which is a process known as is represented by the arrow 2
Explanation:
The different phase transitions that occur in mater are;
1) A phase transition from the solid phase to the liquid phase which occur by heating, represented by the arrow 2 and the process is known as melting
2) A phase transition from the liquid phase to the gaseous phase which occur by further heating the liquid, represented by the arrow 1 and the process is known as evaporation
3) A phase transition from the gaseous phase to the liquid phase which occur by cooling the hot gas, represented by the arrow 2 and is known as condensation
4) A phase transition from the liquid phase to the solid phase which occur by further cooling the liquid, represented by the arrow 5 and the process is known as freezing
5) A phase transition from the solid phase to the gaseous phase which occur by heating the cold solid, represented by the arrow 3 and the process is known as sublimation
6) A phase transition from the gaseous phase to the solid phase which occur by cooling the gas, represented by the arrow 6
Therefore, the phase transition that represent the the cooling of gaseous water to form liquid outside a bottle left outside is represented by the arrow 2

CHEMISTRY PLEASE HELP!! You have 45 grams of Carbon (C). How many moles of Carbon do you have? Use the drop down selections to help you fill in the table and solve the problem.
Answer:
3.75mole
Explanation:
Given parameters:
Mass of the carbon(C) = 45g
Unknown:
Number of moles of carbon = ?
Solution:
The number of moles of a substance can be found using;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of carbon = 12g/mol
Number of moles = [tex]\frac{45}{12}[/tex] = 3.75mole
A coastal area that once supported a thriving fishing industry is overfished. The number of species found living in the marine ecosystem decreases. Which of these activities is most likely to increase the natural biodiversity in the area?
Answer:
Building artificial reefs and limiting fishing activity
Explanation:
Building artificial reefs and limiting fishing activity Introducing non-native species to fill unoccupied habitats and banning fishing Building artificial reefs and increasing fishing activity Eliminating non-native species and encouraging fishing for large predatory fishThe only activity that can successfully increase the natural biodiversity of fishes in the area would be building artificial reefs and limiting fishing activities.
The building of artificial reefs would create several microhabitats for fishes to thrive while limiting fishing activities would ensure that the rate of thriving or multiplication of fishes far outweighs the rate fishes are being removed from the area. Both actions will work synergistically to increase the natural biodiversity of fishes in the area.
The introduction of non-native species can have a negative consequence for the area as non-native species have a history of reducing biodiversity by outcompeting the native species and becoming invasive.
Building artificial reefs and increasing fishing activities would be counterproductive. While artificial reefs can increase the thriving of fishes, increasing fishing activities would take away the gains of the artificial reefs.
Eliminating non-native species and encouraging fishing for large predatory fish will disrupt the ecological balance of the area and might have negative effects on biodiversity.
What makes viruses so dangerous but vaccines so important? i am struggling lol
Answer:
viruses can kill you vaccines can save your life.
Explanation:
Answer:
The effect of leaky vaccines on how disease spreads is explained by the “imperfect-vaccine hypothesis”. It holds that, without vaccination, a very virulent virus can get into a population and kill infected hosts (people or animals) very quickly – before they have a chance to spread it. This means that the virus will die out very quickly too, as all potential hosts will be dead or immune to it.

catalysts are molecules that lower the activation energy for a given reaction. what is the specific term used for biological catalysts?
Catalysts are molecules that lower the activation energy for a given reaction. The specific term used for biological catalysts is Enzymes.
What is catalyst?A catalyst is defined as a substance which increase the rate of the reaction chemical reaction, and lowers the pressure and temperature which are needed to start one, in such a way that it doesn't take participate in the reaction.
What is Activation energy?Activation energy is the minimum amount of energy which must be needed by the compounds foe the production in a chemical reaction. The activation energy of chemical reaction is mainly measured in joules per mole, kilocalories per mole or in kilojoules per mole.
What are Enzymes?Enzymes are the chemical catalysts which accelerate the chemical reactions at the physiological temperatures by decreasing their activation energy.
Thus, we concluded that the biological Catalysts that lower the activation energy for a given reaction is Enzymes.

What state (solid, liquid, gas) is mercury in at the boiling point of water, 100°C? Explain.
Mercury is in a liquid state
Mercury's melting point is somewhere around -34 Degrees Celcius. Thus it should be assumed it will be a liquid at this temperature. Not a gas however as mercury's boiling point is somewhere in the 600 Degree range
One mole of any substance contains 6.022 × 1023 representative particles (atoms, molecules, ions, or formula units). A sample of silver metal consists of 4.26 nanomoles. How many silver atoms does it contain?
Answer:
it contains 2.56 x 10^15.
Explanation:
given no. of moles = 4.26 x 10^-9 atoms
one mole has 6.022 x 10^23 atoms
so it contains 4.26 x 10^-9 x 6.022 x 10^23 atoms
(If we suppose silver's atomic weight as 108.)

+ C In this chemical reaction, how many grams of N2 must be consumed
to produce 265 grams of CaCN2? Express your answer to three significant
figures. The reaction requires grams of N2.
Your answer
I need help PLEAS
Answer:
Mass = 80.6 g
Explanation:
Given data:
Mass of N₂ consumed = ?
Mass of CaCN₂ formed = 265 g
Solution:
Chemical equation:
CaC₂ + N₂ → CaCN₂ + C
Number of moles of CaCN₂:
Number of moles = mass/molar mass
Number of moles = 265 g/ 92.11 g/mol
Number of moles = 2.88 mol
Now we will compare the moles of CaCN₂ and N₂.
CaCN₂ : N₂
1 : 1
2.88 : 2.88
Mass of N₂:
Mass = number of moles × molar mass
Mass = 2.88 mol × 28 g/mol
Mass = 80.6 g
