What is a neutralization reaction and what does it produce?
A neutralization reaction is the reaction between an acid and a base to produce water and a salt. A salt is another name for an ionic compound and the specific salt produced depends on the acid and base involved. The product solution is neutral while the starting solutions are acidic and basic respectively.

Why does Aspirin help during a heart attack?
Platelets are cells that clump together and help to form blood clots. Aspirin keeps platelets from clumping together, thus helping to prevent or reduce blood clots. During a heart attack. Blood clots form in an already-narrowed artery and block the flow of oxygen-rich blood to the heart muscle.

What are the elements that make up living things?
The six most common elements in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. Atoms of these elements combine and form thousands of large molecules. These large molecules make up the structures of cells and carry out many processes essential to life.

Which gas is known as laughing gas?
Laughing gas is nitrous oxide, N2O (more properly called dinitrogen oxide). It is a colorless gas with a sweet odor and taste. Inhalation leads to disorientation, euphoria, numbness, loss of motor coordination, dizziness, and ultimately a loss of consciousness.

What makes red blood cells and white blood cells?
White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. All leukocytes are produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell.

Can pure water conduct electricity?
A solution conducts current when positive and negative ions are randomly dissolved in it. Pure water doesn't have enough ions but when you add HCl you add a strong electrolyte so, after the addition, solution can conduct electricity very well.

How long is a football goal post?
The goal posts must be 18 feet, 6 inches wide and the top face of the crossbar must be 10 feet above the ground. Vertical posts extend at least 30 feet above the crossbar. A ribbon 4 inches by 42 inches long is to be attached to the top of each post.

Do penguins have a tongue?
Penguins have very specialised tongues that are rarely seen since they don't extend out of the beak. Penguins tongues are covered with lots of little spiky spines that all point backward into the throat so that when a penguin catches a fish it is gripped by the spines and cannot escape.

How are comets and asteroids different?
Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago. Asteroids formed much closer to the Sun, where it was too warm for ices to remain solid.

Do evergreen trees lose their leaves?
Deciduous trees shed their leaves usually as an adaptation to a cold or dry season. Most tropical rainforest plants are evergreens, replacing their leaves gradually throughout the year as the leaves age and fall, whereas species growing in seasonally arid climates may be either evergreen or deciduous.

How do you get finger prints?
A person's fingerprints are formed when they are a tiny developing baby in their mother's womb. Pressure on the fingers from the baby touching, and their surroundings create what are called "friction ridges", the faint lines you see on your fingers and toes.

Where are bees not found?
They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients.

Do you weigh less at the equator?
If you weighed 100 pounds at the north pole on a spring scale, at the equator you would weigh 99.65 pounds, or 5.5 ounces less. Your mass, in grams, however would stay the same because 'grams' is a measure of the resistance of a body to being moved and has nothing to do with acceleration or gravity.

What makes a firefly glow?
Fireflies light up to attract a mate. To do this, the fireflies contain specialized cells in their abdomen that make light. The cells contain a chemical called luciferin and make an enzyme called luciferase. To make light, the luciferin combines with oxygen to form an inactive molecule called oxyluciferin.

Which planet rotates the fastest on its axis?
Jupiter is the fastest spinning planet in our Solar System rotating on average once in just under 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System.

What animal is called the ship of the desert?
Camels are the only animals that can carry heavy loads from place to place in the desert because they can go for long periods without eating or drinking water. A camel's hump doesn't carry water, as some believe. Instead the hump is filled with fat, which is a built-in food supply.
