Why must chemical equations always balance?

It is sometimes easier to imagine the atoms that make up a chemical equation as something larger. For example, if one is making salad, he might start with a head of lettuce, a whole tomato and a carrot. He needs to chop these vegetables up to make the salad, but he has not actually made some of the vegetables disappear just because he cut them into smaller pieces. New vegetables have not been created, the components of the salad have just been mixed together. The same is true of chemical equations which begin with a certain amount of one element and end with the same amount, on the atomic leve..

What is the chemical formula for carbonated water?

Carbonated water is also known as club soda, sparkling water, fizzy water, soda water and seltzer. Carbonated water was first made by Joseph Priestly. He discovered a method of infusing water with carbon dioxide by suspending a bowl of water above a vat of fermenting beer.\nIn present times, carbonated water is created by injecting pressurized carbon dioxide into water. The most popular use of carbonated water is in beverages, although in the past, it was thought to have medicinal properties.

What is a concentrated solution?

An aqueous solution contains at least two substances: the solvent, water and a solute — the matter that will be dissolved in the water. The amount of solute that is dissolved in a solvent is the concentration. To keep track of the concentration, you can keep track of the mass. However, many find it easier to measure liquids using molarity, which is the number of moles of solute in a solution divided by the volume of the solution in liters.

What part of a plant produces food?

However, the leaves could not produce food without the rest of the plant. The roots draw up water and minerals, and the stem takes those two items to the leaves. The leaves need both the water and minerals to produce food.\nDuring the process of photosynthesis, plant cells trap sunlight in the leaves. Sunlight is electromagnetic energy. The plant combines the sunlight with the carbon dioxide using the chlorophyll in the cells to make the transformation. In the process, both glucose and oxygen are formed. The glucose is what the plant uses for food while the plant releases the oxygen. The fact ..

Why is DNA called a blueprint?

DNA is a double-helix stranded molecule stored in the nucleus of the cells of all living things. In the human body, which contains around 5 trillion cells, DNA is condensed around protein complexes called histones, to form structures known as chromosomes. Each individual human being contains 46 chromosomes grouped into pairs. A pair of sex chromosomes, or the X and Y chromosomes, determine a person's biological gender, whether the individual is a male or a female. All the other 22 pairs are referred to as autosomes.Chromosomes are composed of genes, which are the fundamental units of here..

How can you find pictures of kidneys?

The purpose of the kidneys is to filter blood and excrete waste products from protein metabolism and muscle contraction in the form of urine. This is accomplished within each kidney via approximately 1 million nephrons that separate urine from the blood. Urine is collected in the kidney pelvis that drains down the ureters and into the bladder.

Is the schefflera plant poisonous?

The effects of eating the plant's leaves or coming into contact with its sap don't last long for humans, but the plant is toxic to dogs and cats, according to the ASPCA. Some dogs and cats that eat schefflera vomit, drool or have problems swallowing. Other side effects include intense burning around the animal's lips, mouth and tongue. The ASPCA recommends calling the animal's veterinarian as soon as possible.

Which property of water is demonstrated when we sweat?

Sweat on the skin's surface utilizes body heat to transition into a gaseous state as it evaporates, producing a cooling effect. Water (sweat) absorbs 580 calories/gram of energy at regular skin temperature to produce the cooling effect of perspiration evaporation. Sweating on the skin usually begins at 37 degrees Celsius or 100.4 degrees Fahrenheit. At boiling point, water uses 540 cal/gm to evaporate.

What is the mass of the pancreas?

The pancreas, located behind the stomach, is an organ that produces various hormones related to digestion and blood sugar control. An enlarged pancreas can be an indication of acute or chronic pancreatitis pancreatic pseudocysts, or an abscess caused by bacterial infection secondary to a pseudocyst. An enlarged pancreas can also indicate a benign or malignant tumor growth. While an increase in mass of the organ can indicate pathology, a larger than average pancreas can be benign. Diagnostics such as MRI, CT, ultrasound and laboratory analysis of enzyme function can determine the cause of the e..
