Answer:
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
I’m not too sure I hope someone answers for you
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
If the formula for density=m/v, you can manipulate this formula to the the mass. After manipulation, you get the equation for mass to be: m=density * volume. With density and volume given, we can find the mass.
mass= (8.9) * 6 = 53.4grams
Answer:
correct substrate to bind the active site of the enzyme.
Explanation:
For an enzyme to catalyze a chemical reaction it is very essential for the correct substrate to bind the active site of the enzyme.
The Active site consists of two parts
1.Binding site
2. Catalytic site
The binding site consists of amino acid residues that bind to the correct substrate while the catalytic site has the amino acids that lead to the catalysis.
The active site's shape is such that only the right substratum easily binds to it and thus the catalytic reaction occurs.
