Answer:

I would say proton and electron are the two most important subatomic particles in an atom

Explanation:

The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.

How does liquid turn into gas? (Question for my sister)
kodGreya [7K]
If you were to take water (like many other materials) and break it up into almost the smallest things you could, you’d get molecules. If the molecules are stuck together really tightly in a regular pattern, then they’re called a solid. The solid form of water is ice. This actually makes a lot of sense, because it certainly does seem like all the little parts of a solid (like ice) are stuck together very tightly.

When you heat something up, it makes the molecules move faster. If you heat up a typical solid, it melts and becomes a liquid. In a liquid (like water), the molecules are still stuck together, but they can move around some. What actually happens is that the molecules are still sort of sticking together, but they’re constantly breaking apart and sticking to different molecules. This also makes sense when you think about water. Water sort of sticks together, but it breaks apart /really/ easily.

If you heat a liquid like water up even more (like if you put it in a pot on the stove), then the molecules will move around so fast that they can’t even hold on to each other at all. When this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam). The process of gas molecules leaving the liquid to go into the gas is called "evaporation." The opposite process is called "condensation."

The total mass of the __________________ and __________________ in an atom is the atomic mass.
Eddi Din [679]

Answer:

protons, neutrons

Explanation:

There are three subatomic particles in all atoms: protons, neutrons and electrons. Of these three, only protons and neutrons are considered to have enough mass to contribute to overall atomic mass of the element.

When a 0.680 g sample of olive oil is burned in a calorimeter, the heat released increases the temperature of 370 g of water fro
Lena [83]

Answer:

the energy value of the olive oil kJ/g = 36.880 KJ/g

Explanation:

we can calculate energy gained by the water which generated by the reaction from this formula :

Q = mc∆t

where:

m is the mass of water= 370 g

c specific heat of water = 4.184 J/g·°C  

∆t is the change or difference in temperature in °C = 38.9 - 22.7 = 16.2 °C

by substitution:

Q = 370g * 4.184 J/g.°C* 16.2°C

   = 25078.896 Joule

the energy value of the olive oil = Q / mass of olive oil

                                                     = 25078.896 Joule/ 0.68 g

                                                     =36880 J/g

                                                      = 36880 / 1000 = 36.880 KJ/g
