Can someone help me out on this ♡​

Answer:

Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."

Answer:

since it has lower mass. the force acting on it results in larger acceleration.

Answer:

Explanation:

Iodine test is used to determine the presence of starch in food items. If iodine is added to any food item and it causes the food item to turn to a blue-black color

mark brainiest please

Answer:

I think he was right but not explaining

Explanation:

I think it is C cause.... the volume of a material is the amount of matter that matterial can hold. it should the the amount of space the whole material takes up.

so C is the answer.

pls make this the brainliest.

not because it is, but because I asked.

Answer:

If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas.

Answer:

Mass is a measure of the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance.

Answer:  The SI system is easier and more consistent.  If the Klingons in the next galaxy know the definitions of metric, they can replicate the measures on their own planet.  With English, they'd need to grab a yardstick the next time they did a crop circle.

Explanation:  I'll use "SI" for the International System of Units.  There are several key benefits;

Answer:

Mass= volume x density

Explanation:

Multiply the density by the volume.

Answer:

[tex]3x - 12 = 0 \\ 3x = 12 \\ x = 12 \div 3 \\ x = 4 \\ thank \: you[/tex]

Answer:x=4

Explanation:

3x-12+12=0+12

3x=12

3x/3=12/3

x=4

nail polish remover float

Answer:

it will float on water

explanation:

Geekette hypothesized that since it floated on the water, like ice does, it must be less dense. ... According to Ken Johnsen, who lists his expertise in chemistry, the components of nail polish indeed make it less dense than water

Answer:

Im not sure if they're all right but i hope this helps <3

Explanation:

nonliving:

- it doesn't need to consume energy to survive

- its not able to regulate its temperature

- they replicate by invading living cells

- living things have cells whereas viruses do not

- they aren't made of living cells

- they don't produce waste products

- they don't grow

living:

- they can adapt to their environment

- living things have different levels of organization and so do viruses

- viruses can infect other viruses. If a virus can get sick it should be considered a living thing.

Answer:

When boiling a substance, the particles obtain more kinetic and potential energy from the heat being delivered. The kinetic energy means that the particles starts moving more intensely, and the potential energy means that the particles start to move away further from each other, which means the substance expands in volume.

Explanation:

When a liquid is heated, the particles gain energy and begin to move faster and faster, expanding the liquid. As the liquid warms, the most energetic particles at the surface escape as vapor from the surface.

A particle is a small localized object to which several physical or chemical properties, such as volume, density, or mass, can be assigned in the physical sciences.

Atoms are small units of matter that contain a number of particles known as subatomic particles. The term particle, on the other hand, refers to any small object.

As a result, the primary distinction between atoms and particles is that atoms are small units composed of multiple particles, whereas particles are minute portions of matter.

When a fluid is subjected to heat, the particles acquire energy and start moving extremely fast, causing the liquid to expand.

The much more energetic particles at the exterior getaway as vapor phase from the surface as the liquid warms.

Thus, the arrangement and movement of the particles gets disturbed when a substance is boiled, and it gets escaped as vapor.

Explanation:

Answer:

Fixed Volume

Explanation:

Solids have a fixed shape and occupy a fixed volume.Because the particles in liquids are very close together barely further apart than in solids, liquids do not easily compress, so their volume is fixed. Gases can also flow, so occupy the shape of their whole container. They do not have a fixed shape.

Isotones are nuclides that have the same neutron number but a different proton number. Therefore the answer is  C. boron and carbon.

Explanation:

They have the same number of neutrons but different number of protons.

They both contain 7 neutrons

Answer:

First of all, Energy is released when water molecules bond.

Explanation:

When a bond is formed its stability increases from their respective atoms.  So energy is released but when we are breaking a bond we are changing a compound to a lower energy state to higher energy state it's stability decreases and requires a bit of extra energy higher stability of bond higher energy required to break it…

Explanation:

Answer:  1 g H2 gas

Explanation:  

8g O2 = 0.25 moles

1g H2 = 0.50 moles [I assume you mean H2, not H.  If it is H, then moles = 1.0 moles H

7g N2 = 0.25 moles

1.5 g He = 0.43 moles

===============

The moles above are based on molecules.  All but He are multiplied by 2 to give the number of atoms.  If H2 is correct, it has the greatest number of atoms.  (Not if it is just H).
