Answer:

solids

Explanation:

Solid is A substance with definite volume and shape. Solids do not flow and therefore do not conform to the shape of their containers. Liquid - A substance with definite volume but without definite shape

Answer:B-Solids

Explanation:

the products are:

CaCO3 Calcium Carbonate

CO2 carbon dioxide

NaCI Sodium chloride

H2O​ Water

Answer: 1, magnesium & mg

2, two energy shells

Explanation:

Answer:

100/20 = 5

Explanation:

3)6 electrons and neon

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

The electron configuration Oxygen (atomic number = 8) :

1s²2s²2p⁴

Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon

₁₀Ne = 1s² 2s² 2p⁶

Answer: it’s the chemicals between the biological

Explanation:

The productivity of photosynthesis affect the productivity of cellular respiration by providing energy.

Photosynthesis is a process where plants prepare their food in the presence of sunlight.

Photosynthesis process chemically illustrated as :

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

From the above it is clear that carbohydrate is produced in the photosynthesis process and this carbohydrate provide energy to the plant for the completion of another chemical process. So, for the cellular respiration plants use this energy.

Hence, the productivity of photosynthesis directly affect the productivity of cellular respiration.

Answer:

The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber

Explanation:

A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.

Number of feed = 555 pounds

Feed cost = $237.21

The main composition of algebraic expressions are:  

• 1. phrases/terms  

• 2. variable  

• 3. constants  

• 4. arithmetic operations  

• 5. coefficients  

• 6. exponent  

Initial weight = 82 pounds

Goal weight = 267 pounds

The difference in weight that must be achieved :

[tex]\tt 267-82=185~pounds[/tex]

The pig will gain 1 pound for every 3 pounds of feed⇒ 1 pound weight=3 pounds of feed

The amount of feed must be given:

[tex]\tt 185~pounds~weight\times 3~pounds~feed=555~pounds~of~feed[/tex]

Feed costs $21.37 per 50 pound bag, so for 555 pounds :

[tex]\tt (555~pounds\div 50)\times \$21.37=\$237.21[/tex]

Answer: Explanation:

Answer:

In the first law, an object will not change its motion unless a force acts on it

In the second law, the force on an object is equal to its mass times its acceleration

In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer:

Boiling water- When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion. ... ice melting - Ice melts because heat moves to the ice from the air.

Answer:

rainfall/water

Explanation:

The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.

Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.

I would give the person I care about the most all my love, time, attention, and respect. It's the only thing that I can give to anyone.

Explanation:

Answer:

I would give it to my mom.

Explanation:

I would give her a lot tbh, but something not too crazy... would be a really nice/pretty necklace or some sort of jewelry.

i would give her a lot, because she deserves so much, she shouldn't have been through the things that she did. And I love her a lot! soo... yeah!

Have a nice day! ( ﾟдﾟ)つ Bye

And make sure that she is, and some other people are always happy, because they deserve so much better

Answer:

So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.

The best answer is

A) The atoms in the mineral get rearranged

Explanation:

A radioactive decay is occurring by the emission of charged particles such alpha or beta to form a new stable atom with changes mass number and atomic number.

Heavy unstable radioactive elements undergo nuclear decay by which they form a stable isotope or new atom with changed atomic number. There are two types of nuclear decays mainly. They are alpha decay and beta decay.

During alpha decay isotopes with higher mass number undergo alpha emission and forming a new species with mass number reduced by 4 units and atomic number reduced by 2 units.

In the case of beta- decay, electrons are emitted from the atom and then forming a new atom with atomic number increased by one unit. For an electron capture process, an electron is captured to the atom forming an element with atomic number reduced by one.

Answer:

When oil and lye are combined and heated, the result is soap. This chemical reaction is called saponification. Without lye, saponification isn’t possible, so lye is necessary to create soap.

Answer:

water, H20

Explanation:

From the given choices, only water has two unshared or lone pairs of electrons in its central atom.

The formula of water is:

              H₂O

H is hydrogen with 1 electron

O is oxygen with 8 electrons and 6 valence electrons

To form the covalent bond, the 6 valence electrons are involved. Two out of the 6 bonds with the two oxygen.

The remaining 4 gives the two lone pairs.

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

Answer:

Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon. ... The carbon-14 method was developed by the American physicist Willard F. Libby about 1946.

Explanation:

Electron is negatively charged particle. When building electric circuits electron flow along the path. so, option C is correct.

Electrons are fundamental to many physical processes, including gravity, electromagnetic interactions, weak interactions, electricity, magnetism, chemistry, and thermal conductivity.

The outer shells of atoms in the common items you encounter are made up of matter particles called electrons.

A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound). One of the three main types of particles within an atom is an electron that is bonded to it.

The other two are protons and neutrons. The nucleus of an atom is made up of electrons, protons, and neutrons together.

Thus, Option C is correct.
