Alpha decay involves the loss of an alpha particle, aka a helium nucleus. This results in the mass number of the original element decreasing by 4 and the atomic number decreasing by 2. Assuming 23942u is uranium (92), the resulting element's atomic number is 90, making it thorium.
The building blocks of protein are amino acids.
Amino acids are a class of organic compounds that contain at least one amino group, -NH2, and carboxyl group, -COOH.
Alpha amino acids , RCH(NH2)COOH, are the building blocks from which proteins are constructed.
The NH group of one amino acid and the COOH group of the other amino acid are joined together and a peptide bond -CONH- is formed between the two amino acids and the product is called a dipeptide.
Answer:
Explanation:
True or false 4 questions help please!
Most mixtures are not physical changes.
True
False FALSE when I add solid NaCl salt to water I no longer have a solid salt, I have a solution of sodium and chlorid ions in liquid water. this is physical change
Chemical Changes do not create a new substance.
True
False FALSE 0ne of the proofs that you have a chemical change is the presence of a new substance
Fire is an example of a Chemical Change.
True TRUE fire is oxygen reacting wiIh mattter to form new compounds
False
Explosions are not chemical changes.
It depends on the explosion if I blow up a balloon until it POPS!! that is physical chame. If I light a firecracker and it explodes, that is a chemical change of oxygen reacting with hot gunpowder
A change in color and odor are both examples of chemical changi
I would rewrite the question as
A change in color and odor both INDICATE a chemical change
and that is
True TRUE
False
F
True Fire is an example of a Chemical Change.
True
False
Explosions are not chemical changes.
True
False
