Answer : The volume of sphere is $2143.6cm^3$

Explanation :

To calculate the volume of sphere, we use the formula:

$V=\frac{4}{3}\pi r^3$ .....(1)

where,

r = radius of sphere

Given :

radius of sphere = 8 cm

Now put all the given values in the above formula (1), we get:

$V=\frac{4}{3}\times 3.14\times (8cm)^3$

$V=2143.6cm^3$

Hence, the volume of sphere is $2143.6cm^3$

When two atoms are bonded and have a large difference in electronegativity: HELP PLEASEEE

Fofino [41]

Answer:

Second option - The bond is very polar

Explanation:

Electronegativity of an basically refers to the degree at which an electron is able to attract electrons to itself.

There are different types of bonds between atoms, depending on the electronegativity of the atoms.

When there is a large difference in electronegativity, it pretty much means that one atom would draw electrons more than the other. When this happens, the bond is said to be polar because there is uneven distribution of the charges.

The second option is the correct answer in thus question.

-- A scientist combines 14 grams of potassium nitrate with an unknown amount of

igor_vitrenko [27]

Answer:

The unknown amount of potassium chloride is 13.6 grams.

Explanation:

The reaction of 14 grams of KNO₃ with KCl produces a total mass of 27.6 grams of the products.

The law of conservation of mass tells us that the total mass of the reactants must be the same that the total mass of the products. So, we can find the mass of KCl as follows:

$m_{r} = m_{p}$
