How many moles of magnesium bromide are formed when 3.0 moles of magnesium reacts with 2.0 moles of bromine?
Mg+Br2 -> MgBr2
Answer:
Explanation:
Hello there, I think this is a limiting agent question.
When 3 moles of Mg is reacted with 2 moles of Br2, because of ratio, we just need 1.5 moles of Br2, so Mg is a limiting agent.
So 3 moles of Mg will make 3 moles of MgBr
Answer:
Use the given functions to set up and simplify
Mg+Br2→MgBr⋅2.
3=
2=
Mg+Br2→gBr⋅2=r2B+gM→MgBr⋅2

what is potential energy
Answer:
The energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
so simple question.
Answer:
Potential energy is stored energy that an object has because of its position.
Explanation:
Consider an example where a ball is thrown from a tall building. The point at which the ball is at its maximum height is said to have the maximum potential energy. As the ball gradually falls down, the potential energy decreases and turns into another form of energy, kinetic energy (energy in the form of motion). The ball at its peak position had stored energy, however, as soon as it begins moving, the stored energy will become less.
You can think of it this way where the ball has less and less distance to cover when falling downwards from the building. This shorter distance covered by the ball is proportional to the potential energy, so when the ball is about to hit the ground, the potential energy will be close to 0.

Differentiate between : Physical change and chemical change
Answer:
chemical change is a where a variation occurs when several reactants are combined or mixed together.
physical change is a process whereby you gain or lose energy as you cool or heat it.

Which phrase best describes a period on the periodic table?
a. elements that are in the same group
b. elements that have the same number of electrons
c. a column of elements
d. a row of elements
Answer:
d. a row of elements
Explanation:
Elements that are in the same group, have same number of electrons and make up a column in a periodic table.
[tex].[/tex]
The phrase which best describes a period on the periodic table is; a row of elements.
The elements in the periodic table are divided into rows and columns. The rows are called the periods while the columns are called the groups.
This means that a period is best described as a row of elements from the foregoing.
Therefore, the correct answer is option D: a row of elements.

Can pure water exist as a liquid at 110° C ? Why or why not?
According to forces of attraction and as boiling point is 100°C pure water cannot exist as a liquid at 110° C.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

The graph below shows the changes in the temperature of ice when it is heated from -20 °C to 100 °C.
Heat curve for ice. The graph shows the changes in the temperature of ice when it is heated from negative 20 degrees Celsius to 100 degrees Celsius. The label for the x-axis reads 'Addition of heat over time.' The label for the y-axis reads 'Temperature (degrees Celsius).' There are labels on the graph (from 'A' to 'E') that designate significant events while applying heat to the ice. Portion AB has a slight incline while increasing the heat from negative 20 degrees to 5 degrees; portion BC stays at 5 degrees for a while; portion CD steadily increases in temperature from 5 degrees to 100 degrees over a significant period of time; portion DE stays at 100 degrees for a while.

Which elements would react most easily with each other? (1 point)
an element with a high electronegativity and an element with a full shell of electrons
an element with a high electronegativity and an element with a single valence electron
an element with a high electronegativity and a second element with a high electronegativity
an element with a high electronegativity and an element with low reactivity
Answer: an element with a high electronegativity and an element with a single valence electron
is the correct answer
_______________________________________________________
Answer:
"Any element with a high electronegativity and an element with a single valence electron would react very easily on contact with each other."_______________________________________________________
"Why?"
For instance, fluorine is the most reactive non-metal element on the periodic table. Due to it's small size, as well as it's strong electronegativity, fluorine has a strong tendency to accept electrons from other atoms and ions. But when Fluorine comes in contact with Hydrogen (a single valence electron element), for instance, it immediately reacts, resulting in an explosion.
