What is a chemical property of carbon?

The reason carbon can make long chains is because it has four open valence electron spots, so it can bind with four other elements all at the same time. Carbon combines with oxygen to form carbon monoxide or carbon dioxide, for example. Carbon dioxide is what humans breathe out during respiration. If the amount of oxygen in the room is limited or used up, it turns to carbon monoxide, which is toxic.\nCarbon creates more compounds than every other element combined. There are several million different carbon compounds currently known to science. The element is required in organic chemistry, but ..

What is the conjugate base of HNO3?

In most cases, the acid molecule that remains after losing a hydrogen ion is an acid's conjugate base. In this example, that conjugate base is the nitrate. To conjugate an acid, it is necessary to place it in water to create a chemical reaction with the H2O molecules. HNO3 is an acid, and it releases a proton into the water as a result of the chemical reaction. This results in the creation of the nitrate conjugate base and a hydronium (H3O+) acid base.

What is the function of the vacuolar membrane?

The membrane of the vacuole is referred to as the tonoplast. This membrane is unique among other cellular membranes due to its incredible flexibility. When the vacuole contains only a small amount of fluid, the membrane is small enough to contain this fluid without empty space. When the cell begins to take on water, however, the membrane is able to stretch rapidly to accommodate so much fluid that this single organelle can then take up 95 percent of the cell by volume. During this process, the tonoplast does not lose its integrity or its ability to continue functioning as an active membrane, a..

How does energy change from one form to another?

Except in a very few circumstances, such as in a superconductor, all energetic interactions produce some sort of resistance. Air is slightly resistant to the passage of light as well as the motion of objects in it. Only a few materials under very specific conditions do not offer some resistance to electrical currents. In all such cases, this property is called resistance, since these objects and substances mean that more energy must be emitted at one location than energy of the same type is received any distance away from the source. The amount of decrease is equivalent to the resistance of th..

Why does scratching a chalkboard make you cringe?

In 1986, three scientists at Northwestern University broke down the sound of a garden tool scraping a chalkboard. They removed certain high, middle or low frequencies and played them back to test subjects who rated their adverse reactions. To the scientists' surprise, people cringed most at the middle frequency sounds and not at the high frequency sounds as they hypothesized.One of the key takeaways from this 1986 study was that the middle frequency sounds were very similar to primate distress calls in the wild. The scientists' theory was that this is an evolutionary condition. Other..

What family does antimony belong to?

The atomic number of antimony is 51, and its atomic weight is 121.760 atomic mass units. Its electron configuration is [Kr] 4d10 5s2 5p3 or 2, 8, 18, 18, 5 electrons per shell.\nPure antimony is quite soft; and, it reacts with oxygen when it is heated. At room temperature, antimony is a shiny gray solid, which melts at 1167.13 degrees Fahrenheit. Antimony is found naturally in the form of a sulphide compound, called stibnite.

What does space smell like?

Polycyclic aromatic hydrocarbons are on Earth too, appearing in coal, oil and many foods. For training purposes, NASA attempts to recreate the smell of space, concentrating on the smell of the moon, with the aid of fragrance maker Omega Ingredients. Astronauts describe the scent as having a spent gunpowder smell. Space further away from stars, outside the galaxy has a wider array of smells, including sugar and sulfur.

Can a human live on Jupiter?

In addition to the harsh conditions, the atmosphere on Jupiter contains very little, if any, oxygen, which is a key component to human survival. The atmosphere is likely hundreds of miles thick, and the planet has no real surface. As the immense pressure acts on the gases toward to the interior of the planet, the atmosphere probably transitions to an environment of liquid hydrogen.

What is a small tear of the interstitial distal supraspinatus tendon?

The supraspinatus muscle runs from the supraspinatous fossa of the top of the shoulderblade to the very top of the upper arm, according to Gray's Anatomy. The distal supraspinatus tendon is the muscle's farthest attachment to this portion of the upper arm. The supraspinatus helps to raise the arm at the shoulder. According to the AAOS, a rotator cuff injury can be painful when lifting the arm out to the side.

What are some examples of cold blooded animals?

Cold blooded animals maintain their body temperature by seeking environments that match the temperature they require. The term "cold blooded" is inaccurate; these animals are now called ectotherms, which means they regulate their body heat by absorbing or releasing heat into their surroundings. They do this using a variety of bodily mechanisms. Fish can sense the water temperature around them and swim to a depth that suits their body temperature. Lizards bask in the sun to increase their body temperature and move in to the shade when they get too hot. Animals in desert regions need to avoid ov..
