One cause of acid rain is the burning of coal that contains a lot of?
Acid rain is a result of chemicals such as sulfur dioxide and nitrogen oxides, often contained in coal, mixing and reacting with the oxygen, hydrogen, and water in the air resulting in acid such as sulfuric acid and nitric acids. The result is the acids dissolved in the rain drops. This acid rain can have corrosive effect on plant and animal life as well as man made art and structures. Carbon Water
When excess fertilizer drains into a lake what may occur harming fish populations?
eutrophicationeutrophicationFertilizer in a lake helps algae grow. Up to a certain point, that is good. The algae turns carbon dioxide into oxygen and adds oxygen to the water. However, after that point, the algae covers the lake. Oxygen from the air can not get to deeper water. Dead algae falls to the bottom of the lake and decomposes. The process of decomposing uses up oxygen. The amount of oxygen in the lake drops below the point where fish can survive. Thus, over fertilization leads to a fish kill.
What is reduction of a metal oxide?
When a metal oxide (such as Copper oxide, CuO) is reduced, it is separated from its oxygen and usually becomes a solid metal again. It usually needs the help of an acid (such as hydrochloric acid or nitric acid) to make this happen. In combination with the oxygen (CuO), the metal has a positive charge (it is a cation). When it is reduced, it gains electrons from a more reactive metal (such as zinc) and its charge drops to 0. Copper is reduced from Cu+2 to Cu(s). The other metal is oxidized. The zinc, in this case, looses electrons and becomes Zn+2. Here is the balanced reaction. CuO(s) +2 HCl (aq) à CuCl2(aq) + H2O The acid strips the Copper from the Oxygen, but the charges are the same. CuCl2(aq) + Zn(s) à Cu(s) + ZnCl2(aq) The copper is reduced and the zinc is oxidized.
How much oxygen inside tornado?
Since the density of the air in a tornado is reduced by the pressure drop the overall concentration of oxygen is lower than it would normally be. Some estimates indicate that in the very largest tornadoes (which have the largest pressure drops) may have as little as 70% the normal amount of air and thus oxygen.
Why does rain come in drops?
Rain comes in drops because water droplets in clouds merge together to form larger drops due to gravity and air resistance. Eventually, these drops become heavy enough to fall to the ground as raindrops.
What does the blood drop off in the lungs?
it drops off co2 (carbon dioxide)
Where does blood drop off oxygen and pick up carbon dioxide?
Blood drops off oxygen and picks up carbon dioxide in the capillaries of tissues throughout the body. Oxygen is released from the red blood cells and diffuses into the tissues, while carbon dioxide produced by the cells enters the blood to be transported back to the lungs for removal.
What gas bubbles out when drops of hydrochloric acid are dropped on marble?
Carbon dioxide gas bubbles out when drops of hydrochloric acid are dropped on marble. This reaction occurs because the hydrochloric acid reacts with the calcium carbonate in the marble, producing carbon dioxide gas as a byproduct.
What is the process where blood picks up oxygen and drops off carbon dioxide called?
When red blood cells pick up oxygen they are said to become oxygenated. The process is oxygenation.
What happens to the carbon dioxide level during hyperventilation in fresh air?
CO2 drops during Hyperventillation
Why would a reptile population would decrease?
Two reasons. First, the general metabolic rate drops, which slows the resporatory rate and the need for oxygen. Second, cold water can dissolve more oxygen and carbon dioxide than warm water can, so respiration is more efficient.
Name 2 things that the blood drop off that the cells use to live?
Oxygen and nutrients are two things that the blood drops off to cells for them to live and function properly. Oxygen is essential for cellular respiration, while nutrients provide energy and building blocks for cellular processes.
What is reason for acid rain?
The rain becomes acidic because Carbon dioxide, Sulphur dioxide and Nitrogen dioxide dissolve in rain drops to form Carbonic acid, Sulphuric acid and Nitric acid.
How do you test for carbon dioxide with a splint?
collect gas from reaction with a test tube, then light spint and insert into the gas filled tube. if splint is extinguished immediately, then its CO2. but limewater test is more reliable
The process where blood moves throughout the body?
As blood moves through the body, the concentration of oxygen decreases as the concentration of carbon dioxide increases in the body and the concentration of glucose in the blood also decreased. This is because body cells require glucose and oxygen for respiration/to produce energy, whilst carbon dioxide is a waste product of repiration thus the amount of carbon dioxide will increase. As it moves past/through the intestines, the concentration of glucose, lipids and ions increase as the small intestines reabsorbs food. As blood moves through the kidneys, the concentration of urea drops significantly however the concentration of dissolved ions may differ depending on what the body needs to retain. As blood moves through the liver, amino acids -> ammonia -> urea.And as it enters the left side of the heart, it has low concentration of oxyden and high concentration of carbon dioxide. As it moves out from the left side of the heart, it is oxygenated and has less concentration of carbon dioxide.
How low can infant oxygen level go before brain damage occurs?
Brain damage can occur if an infant's oxygen level drops below 85-90%. Prolonged periods of low oxygen levels can lead to hypoxia, causing damage to the brain and other vital organs. It is important to monitor infants closely and seek immediate medical attention if there are any concerns about oxygen levels.
How is water made in a car engine?
Small amounts of water vapour can be produced as part of the combustion process. When the petrol / air mixture ignites in the combustion chamber of the cylinders, the waste by-products are carbon monoxide gas plus a small quantity of carbon DIoxide. The carbon dioxide sometimes reacts with left-over oxygen to produce water vapour, which can then condense into droplets in the exhaust system. This is why you can sometimes see occasional drops of water falling from the tailpipes of stationary vehicles that have their engines idling.
