Answer:

Explanation:

Beryllium especially, but Boron as well both exhibit metallic characteristics.

The outside ring of Beryllium contains 2 electrons. It would have to take on 6 electrons to have a ring of 8. The same statement can be made about Boron (except that it would need 5 electrons to make 8). It is easier for the atom to give up 2 or 3 than than to take on 5 or 6. It would not be easy to have a 5 or 6 minus charge on it.

#1. Which one of the following statements correctly defines active site? The active site is a site on the enzyme molecule where

deff fn [24]

Active sites in enzymes are where substrates bind. Once they bind, a catalytic reaction occurs as a complex between substrate and enzyme is formed. Enzymes are termed as biocatalysts or simply catalysts since they speed up the catalytic reaction. After the reaction, they simply revert back to their original form, after having adjusted to fit with substrate.

Activity: A Ferris wheel with a diameter of 60.0 m is moving at a speed of 2.09 m/s. What is the centripetal

GarryVolchara [31]

Answer:

Centripetal acceleration of the wheel is $0.145\ m/s^2$ .

Explanation:

We have,

Diameter of a Ferris wheel is 60 m

Radius of the wheel is 30 m

Speed of the wheel is 2.09 m/s

It is required to find the centripetal acceleration of the wheel. The formula of centripetal acceleration is given by :

$a=\dfrac{v^2}{r}\\\\a=\dfrac{(2.09)^2}{30}\\\\a=0.145\ m/s^2$

So, the centripetal acceleration of the wheel is $0.145\ m/s^2$ .

Answer:

Your hypothesis is incorrect because warm substances rise when in a colder environment. The correct hypothesis would be : "If the 2 chambers of water are poured side by side, the warmer water will float above the cooler layer because warm water rises and cold water sinks."
