There are a couple of ways to determine if a reaction is exothermic or endothermic. Endothermic meaning that heat is added to the reaction to make the reactants interact and exothermic meaning heat...

First, we should recognize that the formula (H2SO4) is not hydrochloric acid. The root "chlor" in "hydochloric acid" denotes the presence of chlorine, which is not present in H2SO4. Hydrochloric...

The cell theory is an explanation of what cells are and why they exist. The three main parts are: 1) All living things are made of cells and their products, 2) New cells are created by old cells...

It's important for scientists to know the properties of matter because all things are made up of matter. Each type of matter has different physical characteristics and scientists need to know and...

The ranking of the given items from largest to smallest is as follows: Organism > Cell > Nucleus > Chromosome > Gene > DNA DNA is a molecule that can be thought of as the blueprint...

Some individuals do in fact bruise easily, they may have an ascorbic acid(Vitamin C) deficiency or some coagulopathy. Perhaps they are taking a blood thinner medication like Coumadin, ASA, or...

One reason for sudden hair and nail growth could be due to an improvement in your overall health. There are many vitamin deficiencies that can cause your hair and nails to grow slowly. Sometimes...

There are two paramount differences between art and science. The first is that art is subjective while science is objective. The second is that art expresses knowledge, most often in the form of...

From smallest to largest: nucleotide, gene, chromosome, genome. Nucleotides are the smallest building blocks of DNA. There are four nucleotides (A, G, T, C) which arrange in pairs to form the long...

Advantages: Bar charts are pretty easy to interpret, and there's a very clear relationship between size and value that allows easy comparison. They're simple to make and most people have experience...

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel...

A material can be a poor conductor of heat, electricity, or both. A poor conductor means that the substance will not easily conduct heat or electricity (or both) as easily as a conductor. For...

Alternatively we can use the conversion of gravitational potential energy (maximum at top of swing with minimum kinetic energy because it is momentarily motionless) to kinetic energy at the bottom...

The golgi apparatus contains vesicles and folded membranes and is involved in cellular transport. It is a packaging organelle. The golgi apparatus packages proteins into vesicles inside of the cell...

Non-reducing sugars do not have the aldehyde group and so they cannot reduce copper sulphate like reducing sugars would do when tested with the Benedict’s reagent. To test for non-reducing sugar,...

The four types of consumers in ecology are herbivores, carnivores, omnivores, and decomposers. Herbivores are consumers who only eat vegetables, plants, grass, or some type of vegetation. An...

Dialect is a special form of speaking belonging to a group. Register is a linguistic term used to describe changing how one talks based on the situation. I will be using To Kill a Mockingbird by...

The reactivities of elements can be predicted by periodic trends (patterns within the Periodic Table.) Let's start with periodic trends. An element's reactivity is its tendency to lose or gain...

According to the biologists Gerald and Teresa Audesirk, all members of the animal kingdom have six characteristics in common. They are as follows: All animals are made up of cells that do not have...

The process that happens to both potato slices is called osmosis, which is a diffusion of water across the semipermeable membrane the potato slice cells possess. The water will either go into the...

A number of body systems are used when we are running. These systems include the nervous system, skeletal system, muscular system, respiratory system and the circulatory system. When we decide to...

Mg reacts with HCl according to this equation: `Mg_((s)) + 2 HCl_(aq) -> MgCl_2_(aq) + H_2_(g)` If this reaction takes place under standard conditions the enthalpy change (∆Hº) can be...

The reliability of an experiment is the consistency of the results. The degree of reliability is shown by the closeness of agreement of data for several repetitions of the experiment. Reliability...

The empirical formula of a chemical compound is CH2O. The molar mass of carbon is 12, the molar mass of hydrogen is 1 and the molar mass of oxygen is 16. The empirical formula of a compound is the...

Precipitation, in the simplest terms, is the process by which water, contained in the clouds, falls down under the influence of gravity. There are several forms of precipitation, including rain,...

Parallel circuits are used in homes because the loads can be operated independently of each other. That means that you can have an electrical item turned on and running without needing to have all...

It's important to distinguish between temperature and climate (there seems to be some confusion in the wording of the question). There are six kinds of climate but the main factors that affect (or...

Sexual reproduction, something that is more familiar to humans as it is how humans replicate, requires two parents (or gene sources) contributing genetic information to an offspring that will be...

There are many advantages to classification, both in science and "out" of it. Classification allows us to see relationships between things that may not be obvious when looking at them as a whole....

When humans breathe in air, most of the time it is through the nose, though we can also breathe in through our mouths. Assuming air comes in through the nose, the correct order is: Nasal cavity....

Data structure, in simplest terms, is data organization for its efficient use. Data structures can be of various types, depending on the application. For example, databases use different data...

A buffer is a solution that resists changes in pH when small amounts of H+ or OH- are added. This system acts as a buffer because the ammonia reacts with acid and the ammonium ion reacts with...

While consulting a veternarian is probably the wisest step to take, there is some general information that is available to you from different sources. One of the basic considerations is the breed...

Let's reason our way through this.Organelles are the substructures (such as mitochondria and chloroplasts) inside cells that perform particular functions. They are therefore smaller than...
