What is covalent bond?
Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.
Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.
Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

Why cathode rays have reducing effect
Answer:
Cathode rays consist mainly of electrons, they ionize substance, this leads to reduction. Any ions produced are collect by an ion trap in the tube therefore anything the beam of electrons hits is going to gain electrons.
During secondary active transport, the movement of one substance down its electrochemical gradient provides the force to move another substance up its electrochemical gradient. When both substances move in the same direction the mechanism is referred to as a(n)
Given what we know about the mechanisms surrounding the biological movement of substances, we can confirm that when two substances in a secondary active transport move in the same direction, it is called a symport.
A secondary active transport harnesses the electrochemical energy generated by its movement of one substance, to aid the movement of the other. These movements can be of two types, depending on the directions:
AntiportSymportAn antiport transport will move both substances in opposite directions, meaning one out of the cell and one into the cell. The transport described in the question is that of a symport, given that it moves both substances in the same direction.

when creating a calculated column in a pivottable, where does the calculated field appear?
Answer:
A calculated field will appear in the field list window, but will not take up space in the source data. In the example shown, a calculated field called "Unit Price" has been created with a formula that divides Sales by Quantity. The pivot table displays the calculated unit price for each product in the source data.
Explanation:
The PivotTable Field List contains calculated fields. Items from other fields that have been calculated display as items.
What are calculated fields?Calculated fields are defined as the fields whose values are determined by other fields' values and perhaps external sources. Data from other fields can be calculated using calculated fields. Calculating the sum of two fields is a simple example, but more complicated calculations, such averaging values from multiple tables or even gaining access to external data, are theoretically feasible.
PivotTable Field List is defined as the Areas part of the Field List allows you to organize the fields wherever you like. It features a field section where you select the fields you wish to display in your PivotTable. Using a pivot table is an interactive method for quickly summarizing enormous amounts of data.

Methods used to separate heterogeneous mixtures include the following: check all that apply. *
Decanting
Filtration
Sifting
Answer:
Filtration, Sifting and Decanting
Explanation:
Heterogenous mixtures can be seperated by filtration and sifting (Also known as sieving). Sifting is the process of parting a mixture using a sieve. Sifting is used to separate solid mixtures that contain molecules of varying sizes. Filtration is the process of separating a liquid from an insoluble solid. A common example is using a funnel and a coffee filiter to seperate the liquide from the insoluable solid. Although there are many other methods for filtration. You can also separate mixtures by decantation. Decantation is the process of separating a liquid from a solid/liquid by removing the liquid layer at the top from the layer of solid/liquid below.

renal calculi contain crystallized calcium, magnesium, and uric acid. explain why patients with hyperparathyroidism would be at risk for developing renal calculi.
Patients with hyperparathyroidism would be at risk for developing renal calculi because of high calcium levels excreted by the kidney.
Hyperparathyroidism occurs when there is over secretion of parathyroid hormone by the parathyroid glands.
The parathyroid hormone is responsible for the following in the body:
Release of calcium by bones into the bloodstream. Absorption of calcium from food by the intestines, and Conservation of calcium by the kidneys.Renal calculi are strong masses of stones deposited in the kidneys or urinary bladder.
When there is excess calcium in the blood due to hyperparathyroidism, the kidneys would be over burdened with the excretion of excess calcium.
That extra calcium in the kidney & the urine leads to kidney stone development ( renal calculi).
Therefore, patients with hyperparathyroidism would be at risk for developing renal calculi because of high calcium levels excreted by the kidney.

Answer:
Nonmetals and nonmetals tend to form covalent bonds.
or
P and S
Explanation:
discuss the solubility differences between the halogens and the halides in both hexane and water. be sure to define what a halogen and halide are to foundation your discussion.
Halides are ionic substances while halogens nonpolar substances. Hence, halides dissolves in water while halogens dissolve in hexane.
A halogen is an element in group seventeen. The name halogen means salt former. This name came about because many of the halogens form salts. Halides are salts formed by the halogens.
Halogens are diatomic covalent molecules. As such, they are nonpolar molecules and can only effectively interact with nonpolar solvents. Benzene is a nonpolar solvent hence it acts as an effective solvent for the halogens.
The halides are polar compounds hence they do not dissolve in nonpolar solvents such as hexane. Rather, halides dissolve in polar solvents such as water due to dipole - dipole interaction between the ions in the halide and the dipoles in water.

A chemistry teacher adds red food coloring to water and students observed the dye spreading out to fill the container. Is the teacher
demonstrating a physical or chemical change?
Answer:
its obviously a chemical change
Explanation: Facts
The addition of the food color in water only causes the change in the cor of water but no new substance is formed. Therefore, the teacher is restarting the physical change.
What is a physical change?A physical change can occur when the characteristics of the matter change but the identity does not. Physical changes are classified as: reversible and irreversible. For example, the melting of water is reversible in nature since the melted ice cube will be refrozen.
Physical change can be described as a kind of change where only physical properties of matter such as odor, color, solubility, etc. can change. During physical changes, there is no chemical bonds are broken or formed between atoms of the substance.
The chemical composition as well as the chemical nature of the substance remains unchanged during a physical change. The molecules of matter can rearrange without changing the internal composition of matter.
Therefore, adding food color to water is a physical change as no new substance formed.

Why do you think that you had to use a thin layer of onion skin, rather than a thick layer for the microscope?
When iodine reacts with starch, it produces a blue-black color. Starch is a white substance which plants use to store food. What structure did you see better because of the iodine? Why did you see this structure better?
From low power to high power, what structures became clearer in the unstained onion tissue?
From low power to high power, what structures became clearer in the stained onion tissue?
What is the shape of an onion cell?
Ques.1: Why do you think that you had to use a thin layer of onion skin, rather than a thick layer for the microscope?
Ans:- It is because, I the onion peel is thick layered, then it will be hard or impossible to see through the microscope.
Ques.2: When iodine reacts with starch, it produces a blue-black color. Starch is a white substance which plants use to store food. What structure did you see better because of the iodine? Why did you see this structure better?
Ans: Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil.
This makes a linear triiodide ion complex with is soluble that slips into the coil of the starch causing an intense blue-black color.
Due to this, we can see the structure better.
Ques.3: From low power to high power, what structures became clearer in the stained onion tissue?
Ans: From lower to higher power, we can see:-
-- Large, rectangular interlocking cells,
-- Clearly visible distinct cell walls surrounding the cells,
-- Dark stained nucleus,
-- Large vacuoles at the center,
-- Small granules may be observed inside the cells (within the cytoplasm)
