Answer:

Polar covalent bond

Explanation:

When the electronegativity difference between two elements A and X is 0.8, the bond AX formed will most likely be a polar covalent bond.

A polar covalent bond is one whose electronegativity difference is between 0.5 and 2.1.

In such a bond type, we have heteronuclear species with one of the species having a higher electronegativity value.

Answer:

The correct answer is D)high specific heat

Explanation:

The specific heat indicates the amount of heat required to raise the temperature of a substance in 1 unit of temperature. The specific heat of water is around 4.18 J/g.°C. That means that 1 gram of water is able to retain a high amount of heat (4.18 J) when the temperature is raised to 1°C. Compared with other substances, this specific heat capacity is higher. Thus, water is a good choice for use in a heat exchanger.

C? i think, the rest just isnt right. i wouldve thought there was an answer that would say "it provides us with more organisms" but the closest one to that is C

Answer:

D

Explanation:

the more genetic variation in a population the better their chances are to survive

Answer:

is there a all of above if not then a i would say

Explanation:

Answer:

- the 2 in this formula is called the subscript. It refers only to the  element preceding it. In this case the F (fluorine).  

- in some chemical formulas it is necessary to use parentheses. The  subscript outside the parentheses refers to all the elements inside  the parentheses. In this example there are: one Al (aluminum), three  N (nitrogen), and nine O (oxygen).

- the 3 in this formula is called the coefficient. It refers to each  element that follows. In this case there would be 3 Ba (barium) and 3  F2 (a total of 6 fluorine).

Explanation:

Answer:

A. the right side

Explanation:

Taking into account the definition of covalent bond, the correct answer is option A.) right side of the periodic table contain atoms that form covalent bonds.

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.

In other words, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule. Atoms share pairs of electrons from their valence shell to achieve the stability of the molecule formed. The tendency of the elements to reach a stable configuration is known as the octet rule.

Finally, since the nonmetallic elements are found on the right side of the periodic table, the correct answer is option A.) right side of the periodic table contain atoms that form covalent bonds.

Sedimentary rocks

Explanation:

Sedimentary rocks are made of bits and pieces of rocks that have been eroded away, shells, and the remains of dead plants and animals. As larger rocks are exposed to the elements on Earth such as rain, wind, freezing, thawing, and plant roots growing, they are slowly worn away.

The formula contains : C. 1 nitrogen atom, 4 hydrogen atoms, and 1 chlorine atom

Given

NH₄Cl compound

Required

The number of atoms

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.

A molecular formula is composed of two or more elements formed of the same or different types.

A subscript indicating the number of atoms forming a molecule

So for NH₄Cl , there are 3 different elements, N, H and Cl, and the number is shown from the subscript

Answer:

because you might have a too much bigger than explosion if you add more baking soda or vinegar

Explanation:

You use the same amount of baking soda and the same amount of liquid for each combination for the explosion.

We know that,

When you use the same amount of baking soda and the same amount of liquid for each combination then be get the explosion.

Baking soda and liquid are base and acid so they react chemically.

Here, the given liquid is vinegar

If you will increase the amount of baking soda and if you will increase the amount of liquid then no reaction

So, you use the same amount of baking soda and the same amount of liquid for each combination for the explosion.

because Phloem tissue consists of a group of specialized cells. Sieve tubes are elongated tubular conducting channels of phloem through which food is transported. The contents of phloem can move in the upward as well as in the downward direction. Therefore, they form two-way traffic in plants.

Answer:

Phloem

Explanation:

Xylem transports water by action of trandpiriation pull, capillary action and root pressure. Phloem consists of sieve tubes and companion cells. The phloem is made of tubes and cells basically.

The molecular formula C₅H₁₀O₅ and The scaling factor =5

Given

Molar mass = 150 g/mol

The empirical formula = CH₂O

Required

The scaling factor

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula

n = the scaling factor

(CH₂O)ₙ=150 g/mol

(12+2+16)ₙ=150

(30)ₙ=150

n=5

The molecular formula : C₅H₁₀O₅

The % Oxygen in the compound Cobalt V Carbonate : 57.42%

Given

Compound Cobalt V Carbonate- Co₂(CO₃)₅

Required

% composition of Oxygen

Solution

Number of Oxygen in Co₂(CO₃)₅ = 3 x 5 = 15

Molar mass of Cobalt V Carbonate- Co₂(CO₃)₅ :

=2.Ar Co + 5.Ar C+15. Ar O

=2.59 + 5.12 + 15.16

= 118+60+240

=418 g/mol

% Oxygen = (15.Ar O / MW Co₂(CO₃)₅) x 100%

% Oxygen = (240/418) x 1005

% Oxygen = 57.42
