Describe how evaporation and condensation work together to create earth's water cycle
Answers
Answer: when water is evaporated from the earth whether that be from bodies of water or plants, when it goes up higher, the temperature drops, causing the water droplets to condense, which means form water. This creates clouds and when the clouds get too big and full, precipitation (rain) happens and the rain falls to the earth. This cycle is then repeated.

What is the electron configuration for helium (He)?
A. 1s1
B. 1s2
C. 1s22s1
D. 1s22s2
Answers
Answer :
B. 1s2
this is your answer....
The electronic configuration is the system of the electron distribution in the shells of the atom. The electronic configuration for He is 1s² as it is a noble gas. Thus, option B is correct.
What is electronic configuration?The electronic configuration is the depiction of the electrons in the orbital level of the atoms around the nucleus. The electrons are distributed in the four orbitals namely, s, p, d, and f.
The orbitals have different sub-levels and can accommodate a different number of electrons. The electronic configuration of helium atom with atomic number 2 can be written as, 1s².
The s orbital can accommodate only two electrons in them and helium having only two electrons gets completely filled. Helium being the inert gas has the most stable configuration.
Therefore, 1s² is the electronic configuration of He.

Answer fast! All transition metals have _______ valence electrons.
Answers
Answer:
2 Answers. Most transition metals have 2 valence electrons. Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). Most transition metals have an electron configuration that is ns2(n−1)d , so those ns2 electrons are the valence electrons.

How are beta particles similar to alpha particles?
Answers
The beta particles are similar to alpha particles in the way that they both are used in the treatment of cancer.
What are the types of radioactive particles?Alpha particles, beta particles, and gamma rays are the three most frequent forms of radiation.
Two protons and two neutrons are joined together to form the alpha particle, which is positively charged.When a neutron becomes a proton and a high-energy electron, it generates a beta particle. The proton remains in the nucleus, but the electron is released as a beta particle from the atom.Similarity between beta and alpha particle is that they both are used in the treatment of cancer.
Hence both particles are used in the treatment of cancer.

The answer is
817.6 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume of silicon = 350 cm³
density = 2.336 g/cm³
It's mass is
mass = 350 × 2.336
We have the final answer as
817.6 gHope this helps you

Lewis structure depicts the shared and the nonshared valence electron in the molecule. The diagram made by student A is correct. Thus, option A is correct.
What is Lewis dot structure?Lewis dot structure is the representation of the lone pairs of electrons or the unshared valence electron pair of the atom or the molecule. They also represent the shared bonds between the same or different atoms.
The structure follows the octet rule and represents the shared, lost, or gained electron as the dot above or at the side of the atom. In a water molecule oxygen has 6 electrons in the outer shell and hydrogen has one each.
The hydrogen is in bonds with the oxygen atom that shares the electron between them to complete their octet. Two pairs of electrons on oxygen are non- shared and are represented as lewis dots above the oxygen atom.
Therefore, only student A correctly drew the lewis structure.

A metal block with a temperature of 30°C is placed inside a bowl of water with a temperature of 45°C. Which of the following will occur when the metal block is placed inside the Bowl water?
Answers
Answer: The water will cool down
Explanation:
Both the water and the metal block will reach Thermal equilibrium which is a state where neither of them will be transferring energy (heat) to the other because they are now of the same temperature.
For instance, if you put a cold can in water to warm it up, the water will keep reducing in temperature while the cold can increases in temperature until both the can and the water have the same temperature.
The same logic applies here. The metal block is cooler than the water so the water will cool down and the metal block will get more heat until both of them achieve a temperature somewhere between the temperatures that both the water and the block started off with.

All of the following are ways energy is transferred EXCEPT ______.
use of batteries
movement of waves
movement of objects
movement of heat
Answers
Answer:
use of batteries
Explanation:
while im not 100% on this, I know the energy transferred between objects is heat and all three of the other answers cause heat or movement of objects and batteries do not.
Energy can be transformed from one form to the other and can tranfered from one medium to the other. All the given are ways through which energy is transferred except the movement of objects.
What is energy conservation?Energy can neither be created nor be destroyed. Thus total energy of a system will be conserved. However, energy can be transformed from one form to the other.
For example in batteries the chemical energy is converted into electrical energy where, the energy is transferred to different electrical components.
Similarly, the electrical energy is converting to mechanical energy and we make the devices working. When an object stays at rest the energy stored in it is called potential energy.
The energy generated by virtue of motion of a body is called kinetic energy. Therefore, movement of an object results in the transformation of potential energy into kinetic energy. But here the energy is not transferred to any other thing.
Movement of heat is the transfer of thermal energy.Movement of waves is the transfer of energy. Thus option C is correct.
