Answer:

Kinetic energy increases.

Explanation:

Kinetic energy is energy you get from moving. The equation for KE depends on mass as well as velocity. If you increase one of these factors, KE will increase too.

Answer:

Solute=the substance which a solvent dissolve to produce homogeneous mixture

Solvent= the substance in which a solute dissolve to produce homogeneous mixture

Explanation:

solvent: The liquid in which a solute is dissolved to form a solution.

solute: The component in a solution, dissolved in the solvent.

Answer:

No.

Explanation:

No, one mole of peas do not fit inside a house because one mole is equals to 6.022 × 10²³ units which is a very large value. mole only use for atoms, ions and molecules etc due to very small size but mole is not used for big sized materials such as peas and other vegetables etc. So that's why we can conclude that one mole of peas did not fit inside a house.

Answer:

B: 2 moles

Explanation:

that my answer I got i think its correct

Answer:

Plants, bacteria, and algae

Explanation: Plants are known to gather food from the sun, algae is a type of plant, and bacteria gather food from the sun while they are in the air.

Answer:

590 g CaCl₂

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

5.3 mol CaCl₂

Step 2: Identify Conversions

Molar Mass of Ca - 40.08 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of CaCl₂ - 40.08 + 2(35.45) = 110.98 g/mol

Step 3: Convert

[tex]5.3 \ mol \ CaCl_2(\frac{110.98 \ g \ CaCl_2}{1 \ mol \ CaCl_2} )[/tex] = 588.194 g CaCl₂

Step 4: Check

We are given 2 sig figs. Follow sig fig rules and round.

588.194 g CaCl₂ ≈ 590 g CaCl₂

Answer:

The halogenation of propane discloses an interesting feature of these reactions. All the hydrogens in a complex alkane do not exhibit equal reactivity. For example, propane has eight hydrogens, six of them being structurally equivalent primary, and the other two being secondary

Answer:

Explanation:

Those are the answers in order, BUT the Goldstein and Rutherford ones are confusing me because Rutherford discovered protons and the nuclear atom. Through my research I also noticed that Goldstein contributed to the discovery of the protons made Rutherford, so I listed him as the one who discovered the proton.

I hope this helps! Have a wonderful night! :D

Answer:

did you have options, cause if you did chose something alond the lines of

Explanation:

A real gas is a gas that does not behave as an ideal gas due to interactions between gas molecules. A real gas is also known as a nonideal gas because the behavior of a real gas in only approximated by the ideal gas law.

Answer:could it be kilo

Explanation:it looks like it has the least letters

Answer:

Elastic potential energy is energy stored as a result of applying a force to deform an elastic object. The energy is stored until the force is removed and the object springs back to its original shape, doing work in the process. The deformation could involve compressing, stretching, or twisting the object.

Answer:

answer c aka it is cheaper than other elements

Answer:

because it's cheap and not hard to purify

Answer:

the atoms of the original substances gain, lose and even share their very own electrons. write the symbols of the elements that form the compound. Write down the valency, and lastly go over valencies. This is all I got so far. I hope this helps

Explanation:

Answer:

Nonmetal

Explanation:

A substance in the chart is a nonmetal because nonmetals are not water soluble, they are poor conductors of heat and electricity and they do not have high melting points like metals.

Explanation:

Chlorine is an element in group 7 on the periodic table.

  It is the second element in this group of halogens

 The element has a total of 17 electrons:

Ground state configuration  = 1s² 2s² 2p⁶ 3s² 3p⁵

Valence electrons are the outermost shell electrons;

  From the configuration: 3s² 3p⁵ is the valence shell

           Number of electrons  = 2 + 5  = 7

Answer:

Remember, chemical reactions follow the law of conservation of mass. Chemical equations show this conservation, or equality, in terms of atoms. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms

Explanation:

Answer:

Yes

Explanation:

i think so as there are 2 h on the left

Answer:

The main difference between the heat of formation and heat of reaction is that heat of formation is the amount of energy either absorbed or released during the formation of a compound whereas heat of reaction is the amount of energy either absorbed or released during any chemical reaction.

I am not sure why your teacher isn't asking for the layers, but here is the list of layers;

A -(topsoil) Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.

E - (eluviated) - Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.

B - (subsoil) Rich in minerals that leached (moved down) from the A or E horizons and accumulated here.

C - (parent material) The deposit at Earth’s surface from which the soil developed.

R - (bedrock) A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.

Answer:

formula units

Explanation:

[tex]$KClO_3$[/tex]  is  potassium chlorate. It is an ionic compound containing potassium, chlorine and oxygen. The ion in potassium chlorate are held together by the ionic bonds in the lattice structure.

A representative particle may be defined as the smallest unit for which the substance exists in its natural form. For most of the elements, atom is the representative particle. Molecule is the representative particle for diatoms and molecular compounds. But for ionic compounds such as  [tex]$KClO_3$[/tex] , NaCl, etc. . the representative particle is its formula units.
