What is the charge that a nitrogen ion will form and explain

Chemistry
1 answer:
vesna_86 [32]3 years ago
5 0

Answer:

A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−. The symbol for the ion is N3−, and it is called a nitride ion.

Covert 1.57 x 10^14 nm= ___m
LekaFEV [45]

Answer:

1.57 x 10⁷m

Explanation:

Given quantity is;

          1.57 x 10¹⁴nm

Now;

            1 nm  = 10⁻⁹

So, let us convert this given quantity;

         1 nm          =             10⁻⁹

  1.57 x 10¹⁴nm  will give 1.57 x 10¹⁴ x 10⁻⁹  = 1.57 x 10⁷m

How do tectonic plates move at convergent subduction boundaries? Insert a drawing with the arrows that show the movement
boyakko [2]

Answer:

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt.

What is the weight in grams of 3.36 x 10^23 molecules of copper sulfate
Llana [10]

Answer:

m=89.0g

Explanation:

Hello!

In this case, since we are given the formula units (molecules) of copper sulfate, it is possible to compute the moles of this compound via the Avogadro's number:

n=3.36x10^{23}molecules*\frac{1mol}{6.022x10^{23}molecules}\\\\n=0.558mol

Now, given the molar mass of copper sulfate which is 159.60 g/mol, the required mass in grams turns out:

m=0.558mol*\frac{159.60g}{1mol}\\\\m=89.0g

Best regards!
