Answer:

l = 0

Explanation:

Second quantum number, also known as angular momentum quantum number (l), represents the shape of an orbital. Several quantum numbers and their corresponding orbital shapes are worth remembering:

l = 0, this is an s-shaped orbital;
l = 1, this is a p-shaped orbital;
l = 2, this is a d-shaped orbital;
l = 3, this is a f-shaped orbital

Notice that the angular momentum quantum number might be identified solely from the letter. Since we're considering a $2s$ orbital, this means we're dealing with an s orbital. As defined above, s-shaped orbital would have an l value of l = 0.

The pressure of a fixed mass of gas is increased from 100 kPa to 600 kPa at a constant temperature. The new volume of the gas is

Dima020 [189]

Answer: The new volume of the gas is smaller.

Explanation:

Volume and pressure are inversely proportional (as one goes up, one goes down). So as you increase the pressure, you decrease the volume.

Why does a negatively charged rod force a stream of water away from the rod?

Zinaida [17]

Answer:

The negatively charged rod will force a stream of water away from the rod because of the "attractive force. "

Explanation:

As we know that water molecules have been randomly arranged. So when a negatively charged rod is put near the stream of water, the molecules present in the water start rotating, unless the positive side will be close to the negative side of the rod. Which results in the generation of the attraction force. Hence, the stream of the water forces away the negatively charged rod. When the water molecules have polarized molecules in it the effect will be stronger than the dust.

A chemist prepares a solution of sodium chloride(NaCl) by measuring out 25.4g of sodium chloride into a 100ml volumetric flask a

labwork [276]

Answer: 4 molL-1

Explanation:

Detailed solution is shown in the image attached. The number of moles of NaCl is first obtained. Since the molarity must be in units of molL-1, the volume is divided by 1000 and the formula stated in the solution is applied and the answer is given to one significant figure.
