Name the gas that naturally occurs in the air and screens out harmful rays from the sun?
Ozone (O3) forms from oxygen (O2) in the upper atmosphere and screens out most of the ultraviolet radiation from the Sun.
What life forms were in the proterozoic eon?
There were no life forms as we know them during the Proterozoic period. With oxygen just then being accumulated in the earth's atmosphere, it brought the first advanced single-celled eukaryotes and multi-cellular life forms.
What is rust and how does it form?
Rust forms when metals containing iron mix with the oxygen in the air or the water and create a compound named iron oxide. This compoumd has water molecules, so we call it a hydrated compound. Chemically and very simply speaking, iron atoms lose a few electrons to oxygen atoms. This process, where electrons are lost from atoms, is the oxidation process. When oxidation occurs it produces a chemical reaction that creates iron oxide
How was oxygen formed?
The first oxygen on earth was produced by a blue green bacteria called cyanobacteria. They had no used for it, it was just waste in their process of making glucose as food using sunlight (the glucose was then fermented when the energy was needed). The waste oxygen poisoned many life forms. Eventually some life forms evolved that could use oxygen and also protected themselves from its poisonous character.
Place the following events into the proper order?
Fertilization takes place, Zygote divides, Implantation occurs, Gastrulation begins, and Heart forms.
Generation of proton gradients across membranes occurs during what?
Generation of proton gradients across membranes occur during both photosynthesis and respiration. The reduction of oxygen which forms water occurs during respiration.Ê
Does reduction of oxygen that forms water occur in photosynthesis?
no, it's during respiration
What type of reaction occurs when iron mixes with oxygen?
it forms iron oxide, and it can/should form rust
What is the reduction of oxygen which forms water?
A reduction is when you add hydrogen to a molecule, so if you were to reduce oxygen twice, O then HO then H2O. Water would be formed.
What forms at the cathode during electrolysis of a metal compound?
reduction reaction.
What forms as an energy source when respiration occurs in the presence of oxygen?
ATP
Which stage of cellular respiration is water produced?
water is made during the electron transport chain (etc) phase.
What product forms when O2 is reduced?
During photosynthesis and cellular respiration, oxygen is converted to water.
What kind of change occurs when a compond is separated into its components?
A chemical change occurs because compound is two elements put together so when they are separated it forms a new substance.
What chemical reactions happen when you put iron in hot water?
oxidation occurs and rust forms on the piece of iron from the oxygen in the water
What is the chemical name of the product when copper reacts with gas in the air?
Copper reacts with the oxygen in the air in a process called oxidation. This occurs in several steps as seen in Kuba Jasinski’s answer. The reactions occur as the copper atoms give up some electrons (oxidation) to the oxygens (reduction) to create ionic compounds. This is a classic example of what is called a redox (reduction-oxidation) reaction.
What happens during anaerobic respiration?
Anaerobic respiration occurs in the absence of oxygen. It releases a small amount of energy and forms lactic acid in the process.
