How cemistry used in agricultura?
we get fertilizers.
Can you name me 2 producers?
the 2 producer is hydroation and cemistry
What are learnt in applied chemistry and chemical engineering?
Chemical engineering deals with applying cemistry and the laws of engineering to the design and operation of commercial scale chemical production and processing facilities.
Is mdma hard to make?
yes and no, you could do it if you had the knowlege. and by that i mean you have at least a college level knowledge of cemistry. with all that said you would also have to get your hands on the equipment and cemicals which are all on the dea watch list and most are illegal. even if you did get your hands on them the dea would know and be at your door. saying this though there are many of people out there who make it most in the Netherlands though.
Bad effect of physical and chemical change on the environment?
Examples of physical changes: transformation of clouds (water as gas) in rain (water as liquid), transformation of rain (liquid) in snow or ice (solids), etc. Examples of chemical changes: formation of smogs, acid rains, water bodies pollution, etc.
Should a seventh grade girl date a ninth grade boy?
It is generally not recommended for a seventh grade girl to date a ninth grade boy due to the difference in maturity levels and life experiences. The age gap at this stage of development can lead to power imbalances and potential risks for the younger individual. It's important for individuals to date within their own age group to ensure healthy and appropriate relationships.
Is ester flammable?
An ester is mostly identifiable by a strong smelling, fruity aroma - so called aromatic esters like, in example, nitrobenzole, the simpliest ester made of benzole (CH6) and conzentrated nitric acid (ca. 68%) which has a strong smell like marzipan. They are the base of most artifical aromatics, esp. orange or strawberry. Always made from an alcohol (alcan, alcene or alcine like Glyzerin) and an anorganic acid. A very spezial case is the well-known high explosive mostly just called "Nitroglycerine", which is in reality no nitrate, but an ester, exactely a glycerine-nitric-acid-ester or, also named as glycerinetrinitrate. The difference to a nitrate is the fact, that at nitrates the Hydrogen-Atoms H+ at the-carbon(ring) are substitutet by NO3+ -groups; at an ester they are substitutet by O-NO3-Groups because they are normally not just surroundet by the alcohol-typical OH-komplexes instead of the pure H-Atoms of pure CxHy-complexes. Glycerin, as example, is a 3-based Alcohol (not C6H5OH like a simple alcohol, but a C6 H3 OH3 -Alcohol, a 3-based Alkine like we in germany say (alkanes (1 OH), alkenes (2 OH), alkines (3 OH) ). in that case, just the Oxygen-bounded H-Atoms will be substituated by the NH3 Nitrogroups, which gives the Molekules an extra Oxygen-Atom between the Carbon-ring and the NH3+ nitrate-Ion, which is correctly not called a Nitrate but an Ester - for his reason the mostly-used trivialname "Nitroglycerine" isn't really correct, it's Glycerine-trinitrate you want to be exactely. The extra-Oxygen-Atom makes the difference between an Ester and a Nitrate, Sulfate and so on. Btw: the here seen C6-molecule is in the well-known shape of the (in cemistry very important) so-called Benzol-Ring (-Molecule), naturally Benzol has the well-known ringshape with an Hydrogen-atom at every 60°-angle (C6 H6) (which is very toxik and highly flammable).
