Chemistry
1 answer:
likoan [24]3 years ago
8 0

Answer:

Freezing point = 1.25

Explanation:

If  we increase the concentration of the solution, the concentration of H+ does not change.

Convert 2.5% in to decimal

2.5%  = 2.5 ÷100

        = 0.025

The freezing point = 0.025 × 50

                               = 1.25

The table shows the specific heat of four substances. The substances are exposed to the Sun for the same length of time. Arrange
Kazeer [188]

Answer: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. Therefore, a high value of specific heat would mean that more heat is needed in order for the temperature to increase. The correct answer would be water since it has the highest specific heat of the choices given.

A particle that has the electron configuration 1s²2s²2p³ would:
notka56 [123]

Answer:

Have 2 filled orbitals and 3 partially filled orbitals.

Explanation:

Hello there!

In this case, according to the given information of the electron configuration for that particle; it is possible for us to infer it has 5 valence electrons, as the electrons on its outermost shell (2). Moreover, we undertand this particle needs three bonds, does not have neither the electron configuration of a noble gas which ends by p⁶ nor that of an alkali earth metal as it ends by s².

Therefore, we infer the correct answer is Have 2 filled orbitals and 3 partially filled orbitals because according to the Hund's rule, the s orbital is fulfilled and the p orbital has 1 electron orbital fulfilled and two partially filled orbitals.

Regards!
