Atoms cannot be created or destroyed by chemical reactions. They just have a some bonds rearranged is all.
The enzyme must attract substrates to its active state.
At the end of the reaction, products dissociate from the surface of the enzyme
Answer:HNO3 + NaOH → H2O + NaNO3
Explanation:
Answer:
4.17e+22 atoms of tin are present in the cube
Explanation:
We don't require the size of the cube. With the mass and the molar mass of tin = 118.7 amu we can find moles of Tin. As 1 mol = 6.022x10²³ atoms we can find the number of atoms:
<em>Moles Tin:</em>
8.21g * (1mol / 118.7g) = 0.0692 moles Tin
<em>Atoms Tin:</em>
0.0692 moles Tin * (6.022x10²³ atoms / mol) =
<h3>4.17e+22 atoms of tin are present in the cube</h3>
