Answer:

Deep cold water has a high density and warm, shallow water has a low density.

Explanation:

Because when it is cold, water shrinks together it acts as a factor for it to have a high density and it's deep which also acts as a factor because to deeper something is near the Earth's core the more pressure it has leads to high density as well because gravity is stronger near the Earth's core. When water is warm it has a low density which is the first factor and because it is shallow it is far from the earth's core it has a lower density and pressure.

The smallest particle of an element which is indivisible and takes part is chemical reaction as a whole without division is called an atom.

Explanation:

i think the answer is....b

The diagram that represents single replacement reaction is:

b.

This reaction is also known as displacement reaction. It is a reaction in which one element is substituted for another element in a compound. When a replacement reaction occurs, a new aqueous compound and a different pure element will be generated as products. For example:

[tex]2HCl(aq)+Zn(s)--->ZnCl_2(aq)+H_2(g)[/tex]

Thus, option b is correct.

Answer:

d

Explanation:

because it’s moving the most spots to the left

The acidity or alkalinity of a solution depends upon its hydronium ion concentration and hydroxide ion concentration. Here among the given solutions, the solution D has the highest pH. The correct option is D.

The pH of a solution is defined as the negative logarithm to the base 10 of the value of the hydronium ion concentration in moles per litre. The pH scale is introduced by the scientist Sorensen. It is more easy to express the concentration of H₃O⁺ using this method.

The equation used to calculate the pH of the solution is given as:

pH = -log[H₃O⁺]

For 0.1 M

pH = -log[0.1] = 1

For 0.01 M

pH = -log[0.01] = 2

For 0.001 M

pH =  -log[0.001] = 3

For 0.0001 M

pH =  -log[0.0001] = 4

So solution D has the highest pH which is 4.

Thus the correct option is D.

Answer: N2F4

Explanation:(NF2)x2 = N2F2

The compound X has a molar mass of 104.01·gmol−1 and the following composition: element mass % nitrogen 26.93% fluorine 73.07%, then the molecular formula of X is N2F4.

Molecular formula is defined as a chemical formula that give the total number of atoms of each elements in each molecule of a substance.

It can also be defined as a phrase that specifies the number of atoms of each element in a complex molecule.

It represents the actual number of each atom in a molecules.

It tells us which atoms and how many of each types of atoms are present in a molecule.

NF2 x 2 = N2F4

Thus, the compound X has a molar mass of 104.01·gmol−1 and the following composition: element mass % nitrogen 26.93% fluorine 73.07%, then the molecular formula of X is N2F4.

Answer:

A. Offspring are genetically identical to the parent.

That's the answer. I hope it helps!

The statement which describes asexual reproduction but not sexual

reproduction is A. Offspring are genetically identical to the parent.

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.

The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent.

An Asexual reproduction means that the parent organism will simply split into two child organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA.

Therefore the child and the parent organism will contain exactly the same genetic material - the correct answer is A.

Answer:

Flow rate is how fast a fluid moves. The flow rate can depend on several factors. These factors are the type of fluid that you are using, the force that is pushing on a fluid, the size of the pipe the fluid flows from and the type of surface the fluid flows over. Viscosity is the resistance of a fluid to flow.

Explanation:

The best lewis structure for [tex]Cl_2[/tex] is in option 2.

Na or sodium is the cation in the reactant.

Cl or chlorine is the anion in the reactant side.

NaCl is the product of the reaction.

Lewis Structure is a very simplified representation of the valence shell electrons in a molecule.  It is used to show how the electrons are arranged around individual atoms in a molecule.  Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.

Chlorine is a group VIIA element in the periodic table and contains seven electrons in its last shell.  

Valence electrons are given by chlorine atoms = [tex]7\times2=14[/tex]

Total valence electrons = 14

So, each of Cl is surrounded by three pairs of dots, connected by a single line. So, the best lewis structure for [tex]Cl_2[/tex] is in option 2.

Actually Welcome to the Concept of the Lens and Ray Optics.

We must understand the Concept that,

1.) When a beam of parallel light pass through a Convex lens, all the rays get deviated and converges to a special point at the axis that is a Focus.

2.) When a beam of light passes through the Concave lens,the light beams diverge from one another forming a virtual focus in the primary side of lens,

Hence the above given diagram beam rays are diverging, it is a CONCAVE LENS
