The answer is the first option. Enzyme and substrate bind using a lock-and-key mechanism. Enzymes act on a specific substrate and a substrate needs a specific enzyme, this is what is called a lock-and-key mechanism. Enzymes and substtates are like a key and a lock, one is for each other.

Lithium hydroxide reacts with hydrobromic acid(HBr) to produce lithium bromide and water. If you

sweet-ann [11.9K]

Answer:

3.00 moles of Lithium bromide will be produced

Explanation:

The reaction that takes place is:

LiOH + HBr → LiBr + H₂O

By looking at the reaction equation, we can see that the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr). Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.

Decide which element probably has a boiling point most and least similar to the boiling point of cesium.

natka813 [3]

Answer:

Take a look at the attachment below

Explanation:

Take a look at the periodic table. As you can see, Rubidium is the closest element to Cesium, and happens to have the closest boiling point to Cesium, with only a difference of about 30 degrees.

Respectively, you would think that fluorine should have the least similarity to Cesium with respect to it's boiling point, considering it is the farthest away from the element out of the 4 given. This is not an actual rule, there are no fixed trends of boiling points in the periodic table, there are some but overall the trends vary. However in this case fluorine does have the least similarity to Cesium with respect to it's boiling point, a difference of about 1,546.6 degrees.

Hope that helps!
