Solve if an element has a charge of 2+, how many more protons does it have than electrons? protons

1 answer:

8 0

To determine how many protons are present, simply know or use the following equation

X = number of protons
Y = number of electrons
Z = formal charge of the element

X - Y = Z = 0 for a neutral atom

X - Y = 2

Then to solve for x

X = Y + 2.

This means that we would need an additional 2 more protons than electrons.

Which compound contains a radical

slamgirl [31]

The compound that contains a radical is called NaOH.

Explanation:

Radical, also called Free Radical, in chemistry, a fragment that contains at trivial one unpaired electron. Most molecules include even numbers of electrons, and the covalent chemical bonds including the atoms commonly within a molecule normally consist of pairs of electrons jointly shared by the atoms combined by the bond.

It is known that the kinetics of recrystallization for some alloy obey the Avrami equation andthat the value of n in the exponen

Paul [167]

Answer:

rate of recrystallization = 4.99 × 10⁻³ min⁻¹

Explanation:

For Avrami equation:

$y = 1-e ^{(-kt^n)} \\ \\ e^{(-kt^n)} = 1-y\\ \\ -kt^n = In(1-y) \\ \\ k = \dfrac{-In(1-y)}{t^n}$
