**H-F bond is polar covalent**, Pb-F bond is ionic! Despite all of this, the name for the HF compound follows the conventions for naming an ionic compound!

**H-F bond is polar covalent**, Pb-F bond is ionic! Despite all of this, the name for the HF compound follows the conventions for naming an ionic compound!

Of the 4 different types of chemical bonds, **covalent bonds are known to be the strongest and the bonds formed via Van der Waals forces are known to be the weakest**. The ranking is: Covalent bond > ionic bond > hydrogen bond > Van der Waals forces.

The issue with biochemistry is that **it tends to involve a lot of memorization**. This is almost necessary! The sheer complexity of biological systems, metabolic pathways, enzyme design, etc. make the field almost impossible to navigate without a certain biochemical vocabulary stored away in your brain.

So the answer is: **Yes, if you have the necessary other talents, even average intelligence will allow you to get an PhD**.

A power triangle **has four parts: P, Q, S and θ**. The three elements which make up power in an AC circuit can be represented graphically by the three sides of a right-angled triangle, in much the same way as the previous impedance triangle.

1 Definition. In solid-state chemistry, the **nonstoichiometric compound** represents a uniform physical phase in which unit cell parameters vary with their composition in a continuous manner, and free energy is a function of composition and temperature of the system.

**Things you should never say in a job interview**

- Negativity about a previous employer or job.
- "I don't know."
- Discussions about benefits, vacation and pay.
- "It's on my resume."
- Unprofessional language.
- "I don't have any questions."
- Asking what the company does.
- Overly prepared answers or cliches.

Algebra is **the branch of math that uses variables as the missing pieces of information**. A variable is a letter that stands for a specific number. So, in algebra, we solve problems by finding the missing information represented by the variable.

Definition of static pressure

: **the force per unit area that is exerted by a fluid upon a surface at rest relative to the fluid**.

principal. • **the amount of money borrowed or invested,** **on which interest is calculated**.

Required ratio = 60 : 90 = **2 : 3**.

At the most it can be equal to m. If m itself is the least positive such that am=e, then we will have O(a)=m. Since **1 is the identity element, its order is 1**. Hence the order of -1 is 2.

Computer science is **the study of computers and computing as well as their theoretical and practical applications**. Computer science applies the principles of mathematics, engineering, and logic to a plethora of functions, including algorithm formulation, software and hardware development, and artificial intelligence.

The focal length of a lens system is defined as **the distance from the lens center to a point where parallel rays are focused on the optical axis** (often termed the principal focal point).

**The try-catch is the simplest method of handling exceptions**. Put the code you want to run in the try block, and any Java exceptions that the code throws are caught by one or more catch blocks. This method will catch any type of Java exceptions that get thrown. This is the simplest mechanism for handling exceptions.

An error is something you have done which is considered to be incorrect or wrong, or which should not have been done. Type of error - : There are three types of error: **syntax errors, logical errors and run-time errors**. (Logical errors are also called semantic errors).

**Concepts are based on our experiences.** **Concepts can be based on real phenomena and are a generalized idea of something of meaning**. Examples of concepts include common demographic measures: Income, Age, Eduction Level, Number of SIblings.

The symbol dydx. means **the derivative of y with respect to x**. If y=f(x) is a function of x, then the symbol is defined as dydx=limh→0f(x+h)−f(x)h. and this is is (again) called the derivative of y or the derivative of f. Note that it again is a function of x in this case.

The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants **synthesize their own food through the process of photosynthesis** and thus are called the producers.

**To help you get started, here are 5 important Excel functions you should learn today.**

- The SUM Function. The sum function is the most used function when it comes to computing data on Excel.
- The TEXT Function.
- The VLOOKUP Function.
- The AVERAGE Function.
- The CONCATENATE Function.
