Question 8 What is the effective nuclear charge for a 2nd row electron in sulfur

Chemistry
1 answer:
miss Akunina [59]2 years ago
7 0

Answer:

The effective nuclear charge for a 2nd row electron in Sulfur is +8

Explanation:

Zeff = Z (# of protons) - S (# of shielded electrons)

Since there are 8 electrons in the first and second rows combined, there are 8 shielding electrons.

The number of protons in Sulfur is 16.

Therefore,

Zeff = 16 - 8

Zeff = 8

(It's been awhile, so I am not 100% sure)

What is the volume of 40g of sugar given it’s listed density
lora16 [44]

Answer:

25.157 cm³

Explanation:

Data Given:

Mass of Sugar (m) = 40g

Density of sugar given in literature = 1.59 g/cm³

Volume of Sugar = ?

The formula will be used is

                              d = m/v ........................................... (1)

where

D is density

m is the mass

v is the volume

So

Rearrange the Equation (1)

                              d x v = m

                               v = m/ d         ................................................ (2)

put the given values in Equation  (2)

                       v = 40g / 1.59 g/cm³

                       v = 25.157 cm³

volume of 40 g of sugar = 25.157 cm³

A student places three ice cubes in a beaker and allows them to partially melt. if she measures the temperature of the water in
atroni [7]

She will most likely observe that the temperature does not change during melting because the heat absorbed is used to overcome intermolecular forces rather than to increase the kinetic energy of the particles if she measures the temperature of the water in the beaker.
