Which of these statements is incorrect regarding an atom of the element scandium?

Chemistry
1 answer:
Dovator [93]3 years ago
7 0

The answer is C.

Scandium has 24 neutrons, not 21.

Scandium is a metal that is silvery in color. When exposed to air, it tends to tarnish.  It burns quite easily and will react  with water. Scandium was discovered by Lars Fredrik Nilson in the year 1879 in the country of Sweden and its name is from the Latin word Scandia, meaning Scandinavian.

Other properties of Scandium include:

Melting point: 1539.0 °C

Boiling point: 2832.0 °C

Density: 2.989 grams/cm³

Normal phase: Solid

Family: Transition metals 

Period:  4

1. A gas has a volume of 45 L at a pressure of 140 kPa. What is the volume when
pishuonlain [190]

Answer:

The new volume of the gas is 21 L.

Explanation:

Volume of a gas is inversely proportional to its pressure at constant temperature such that,

V\propto \dfrac{1}{P}

or

P_1V_1=P_2V_2

We have,

V_1=45\ L\\\\P_1=140\ kPa \\\\P_2=300\ kPa

It is required to find V₂. Using above law or Boyle's law such that :

V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{140\times 45}{300}\\\\V_2=21\ L

So, the new volume of the gas is 21 L.

Benzene would react_____________.
Vlada [557]

Answer: Benzene is less reactive than methylbenzoate and more reactive than Nitrobenzene

Explanation:

This is because the methyl group on the benzene ring is an electron donating group leading to the activation of the ring and subsequently leading to more canonical resonance structure at the intermediate stage of the reaction enhancing the faster reactivity

However for the Nitrobenzene the nitro group is an electron withdrawing group leading to a slower activation and less resonance canonical structure at the reaction intermediate leading to a slower reaction than the reaction of benzene without the nitro group
