Answer: Carbon can form single, double, and triple bonds is a characteristic of a typical carbon atom.Carbon is one of the most abundant and essential chemical elements on earth. Carbon has an atomic number of 6 and does not dissolve in water. Carbon is nonmetallic and tetravalent (has four valence electrons). Carbon atoms have the ability to form single, double, and triple covalent bonds with other atoms. Carbon atoms can bond together in various ways (allotropes) and they include graphite, diamond, and amorphous carbon.
Explanation:
Enzymes belong in the category of proteins
Answer: proteins
The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.
Explanation:
we can track climate patterns back to us on earth and the excessive use of fossil fuels and other gasses contribute to this - its basically proven that we are the reason climate change is a thing. climate will change by itself by us humans are causing this to be much faster than it should be
