molar mass Mg = 24 g/mol ; MgF2 = 62 g/mol
<span>Mg + 2 NaF = MgF2 + 2 Na
</span>
24 g Mg ------------ 62 g MgF2
5.50 g Mg ---------- ( mass MgF2)
mass MgF2 = 5.50 x 62 / 24
mass mgF2 = 341 / 24
= 14.208 g of MgF2
hoope this helps!
Around a transform boundary between two plates that slide past each other.
Each atom has a few isotopes, which are atoms with the same amount of protons, but more or less neutrons. This doesn't affect the atom greatly, because neutrons have no charge. The main differneve between isotopes is the weight. Neutrons have the most mass out of protons, electrons, and neutrons, so isotopes with more neutrons would be heavier.
If two atoms are isotopes of the same element, the atoms must have the same amount of protons.
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.
Answer:
THE INITIAL VOLUME OF THE STOCK SOLUTION IS 0.0392 L OR 39.2 mL
Explanation:
To calculate the volume of a solution before dilution, we make use of the dilution formula;
C1 V1 = C2 V2
C1 = the concentration of the stock solution = 15 M
V 1 = the volume of stock solution = ?
C2 = concentartion of final solution = 2.35 M
V2 = volume of final solution = 250 mL = 250/ 1000 = 0.25 L
Rearranging the formula, we obtain;
V1 = C2V2 / C1
V 1 = 2.35 * 0.25 / 15
V1 = 0.5875 / 15
V1 = 0.0392 L
the initial volume of the stock solution is 0.0392 L or 39.2 mL
