A student lifts a bag from the floor to his or her shoulder 1.2m above the floor, using a force of 50N. How much work does the student do on the bag ?

Answers

The formula for work is force x distance, and it is measured in joules, so the answer would be:

1.2m x 50N = 60J

60 J work does the student do on the bag.

The formula for work is as follows:-

[tex]W=F\times d[/tex]....(1)

Here, F is the force, and d is the distance moved in the direction of force.

Substitute 50 N for force and 1.2 m for distance in the equation (1) as follows:-

[tex]W=50\ N\times 1.2\ m\\\\=60\ Nm\\\\=60\ Joule[/tex]

Hence, the value of work is 60 J.

what is an oxidation reaction? ​

Answers

Definition:A reaction when an atom or compound loses one or more electrons.

It is a reaction is a type of chemical reaction that involves a transfer of electrons between two species.

Oxidation is gain of oxygen

For Example:

Fe + O2 —(H2O)—> Fe2O3

Look at the unbalanced reaction below for the combustion of hydrogen gas. What needs to be done to balance the reaction? _ H2 + _O2 LaTeX: \longrightarrow⟶ _H2O

Answers

Answer:

The given equation H2 + O2 => H2O is not balanced as the oxygen atom on the right side do not have the same number of atoms as of the left side.

In a balanced equation, the number of atoms on both sides are equal. So in this case, we are required to change the coefficient in front of H2O, in order to make oxygen atom balance, for that we need to change the coefficient of H2 as well.

It means to make the given equation balance we need to change the coefficient in front of H2 and H2O.

Balance equation: 2H2 + O2 => 2H2O

Compare which element would have larger first ionization energy: an alkali metal in Period 2 or an alkali metal in Period 4?

AW: I think it would be alkali metal on period 2

Answers

Answer:

An alkali metal present in period 2 have larger first ionization energy.

Explanation:

Ionization energy:

The amount of energy required to remove the electron from the atom is called ionization energy.

Trend along period:

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.

Trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.  Thus alkali metal present in period 2 have larger ionization energy because of more nuclear attraction as compared to the alkali metal present in period 4.

A car accelerates from 0 to 72 km/hour in 6.0 seconds. What is the car's acceleration?

Answers

The car's acceleration is 12 km/second^2

The acceleration of the car is equal to 3.33 m/s² with a velocity of 72 Km/hr.

What is acceleration?

Acceleration can be demonstrated as the rate of change of velocity over time. The acceleration can be explained as vector quantity due to both magnitude and direction. Acceleration is defined as the 2nd derivative of the position of the object w.r.t. time.

According to Newton's 2nd law of motion, the force exerted is equal to the mass times of acceleration of an object.

a = F/m

or, a = dv/dt

Given, the final velocity of the car, v = 72 Km/hr

v = 72 × 1000/3600 m/s

v = 20 m/s

The time is taken by car to travel, t = 20 s

The acceleration of the car, a = (20 - 0)/(6 - 0)

a =  3.33 m/s²

Therefore, the acceleration of the car is 3.33 m/s².

Use the periodic table to determine which statement below is true of the element Bromine (Br).

•Bromine will lose 7 valence electrons to become a negative ion.
•Bromine will lose 7 valence electrons to become a positive ion.
•Bromine will gain 1 valence electron to become a negative ion.
•Bromine will gain 1 valence electron to become a positive ion.

Answers

Answer:

The correct option is;

Bromine will gain 1 valence electron to become a negative ion

Explanation:

Bromine can be found in period 4 in group 17 of the periodic table and is an halogen

The electron configuration of bromine can be presented as follows;

Electronic configuration 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁵

Therefore, an atom of bromine has 2 + 5 or 7 electrons in its outermost shell, which makes it have one less electron to complete a full octet structure and therefore, bromine has a strong affinity for electron to complete its octet structure and it is thus a strong oxidizing agent.

When bromine enters into a chemical reaction and gains the one valence electron it becomes a negatively charged ion.
