Elements in group 17 want to lose seven valence electrons and elements in group 1 want to gain seven valence electrons to become stable ions.

Answers

Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups. hope it helped

Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. Chloroplasts help turn sunlight into food that can be used by the cell, a process known as photosynthesis

Someone help with this ions and isotopes worksheet?

Answers

Isotopes are atoms of the same element that have different numbers of neutrons. Protons are positively-charged particles found in the nucleus of an atom.

Electrons are negatively-charged particles found in the outer shell of an atom. The charge on an element is determined by the number of protons and electrons present in the atom.

a.) Li+:  number of protons = 3

Number of electrons = 2

charge of Li+ = +1

b.) Be2+: number of protons = 4

Number of electrons = 2

charge of Be2+ = 2+

c.) C4+: number of protons = 8

Number of electrons = 4

charge of C4+ = 4+

d.) O2-: number of protons = 8

Number of electrons = 10

charge of O2- = -2

e.) N3-: number of protons = 7

Number of electrons = 10

charge of N3- = -3

f.) C4- : number of protons = 4

Number of electrons = 4

charge of C4- = -4

g.) 14C6: The mass number = 14

Atomic number = 6

Number of neutrons = 8

h.) 18O8:  The mass number = 18

Atomic number = 8

Number of neutrons = 10

When we drink water, it is absorbed into our blood through the digestive tract. If the concentration of water in body cells is low, cells must get water from the blood. What process allows water to enter body cells from the blood?

Answers

Answer:

Osmosis

Explanation:

Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.

Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.

Answers

Answer:

The Outer-most Electron shell contains the valence electrons.

Bonus Info:

Valence Electrons are used by atoms to make ionic bonds.

Answer:

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.12 g/mol

Answers

Answer:

C4H8O4

Explanation:

Let (CH20)x

C=1*12.01=12.01     (12.01, 1.01, 16.00 Avg mass of elements)

H=2*1.01=2.01

O=1*16.00=16.00

12.01 + 2.01 + 16.00 = 30.03

120.12/30,03=4

==> (CH2O)4 = C4H8O4

The molecular formula of the molecule that has an empirical formula of [tex]CH_2O[/tex] is equal to [tex]C_4H_8O_4[/tex].

Given the following data:

Empirical formula = [tex]CH_2O[/tex]Molar mass = 120.12 g/mol.

Scientific data:

Molar mass of oxygen = 16 g/mol.Molar mass of hydrogen = 1 g/mol.Molar mass of carbon = 12 g/mol.

To determine the molecular formula of the molecule that has an empirical formula of [tex]CH_2O[/tex]:

First of all, we would find the molar mass of [tex]CH_2O[/tex]:

[tex]CH_2O =12 +(1\times2)+16\\\\CH_2O =30\;g/mol[/tex]

For molecular formula:

[tex](CH_2O)n = 120.12\\\\30n = 120.12\\\\n=\frac{120.12}{30}[/tex]

n = 4.0

[tex](CH_2O)_4 = C_4H_8O_4[/tex]

c. accelerate in the direction of the smallest force.
D. resist any change in movement.

Answers

C I think maybe I aM right or 1

Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will: A. move to the left.

Given the following data:

Upward force = 50 Newton.Downward force = 50 Newton.Rightward force = 30 Newton.Leftward force = 40 Newton.

A net force can be defined as the vector sum of all the forces acting on an object.

Hence, net force is the sum of all forces acting simultaneously on an object.

To determine the direction in which the ball would move if the four forces shown are applied at the same time:

For the downward and upward force:

[tex]Net\;force = 50-50\\\\Net\;force = 0\;Newton[/tex]

For the rightward and leftward force:

[tex]Net\;force = 40-30\\\\Net\;force = 10\;Newton[/tex]

Since the rightward force is greater than the leftward force by a magnitude of 10 Newton, the ball will move to the left.
