Explanation: The process wherein the enzymes change their shape is called as induced fit. It is the precision aligning of enzymes essential for catalytic activity which is caused by the binding of the substrate as enzymes possess active sites. Hence, as the substrate approaches the enzymes, the enzyme alters its shape.

a compound is found to contain 31.1% sulfur and 68.9% chlorine determine the empirical formula for the sulfur and chlorine sampl

ollegr [7]

Answer:

Empirical formula = S₁Cl₂ = SCl₂

Explanation:

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound.

This compound contains 31.1% sulfur and 68.9% chlorine.

That is 100g of the compound contains 31.1 g of sulfur and 68.9 g of chlorine.

Convert the mass of each element to moles using the molar mass from the periodic table.

Moles of Sulfur = $\frac{31.1}{32.065 } \\$

= 0.9699

Moles of Chlorine= $\frac{68.9}{35.453 } \\$

= 1.9434

Divide each mole value by the smallest number of moles calculated.

Units of sulfur = $\frac{0.9699}{0.9699} \\$

= 1

Units of Chlorine = $\frac{1.9434}{0.9699} \\$

= 2

Empirical formula = S₁Cl₂ = SCl₂

Based upon the valence electrons as taken from the periodic table, the formula for rubidium (Rb) chloride (Cl) is:

kati45 [8]

Rubidium (Rb) is in group 1, so it has a valence charge of +1.
Chlorine (Cl) is in group 17 or the halogens, so it has a valence charge of -1.

Since both elements have the same valence charges, just of opposite signs, this means that only 1 atom of each element is needed to create a stable bond. The formula for rubidium chloride will be RbCl.

in order to dilute 1.0L of a 6.00M solution of sodium hydroxide to 0.500M concentration, how much water (in mL) must you add?

quester [9]

Another M1V1=M2V2
V1=1.0L 
M1=6.00M 
M2=0.500M 
V2=?? 
(6.00M)(1.0L)=(0.500M)V2 
Solve for V2 you get 12L or 12000mL
