Answer:

An anion

Explanation:

An ion of flourine wife form an anion. What is an anion? An anion is a negatively charged atom.It occurs as a result of gain of electron by an atom to stabilize it's octet structure.

This is a common phenomenon for non metals and halogens are a good example of that which are strongly electronegative with electronic configuration of 2,7......

Which two types of cells are involved in fertilization?

$\sf\purple{D.\: egg\: cell;\: sperm \:cell}$ ✅

Gametes are an organism's reproductive cells. The female gametes are called ova or egg cells, and the male gametes are called sperm.
During fertilisation, the gametes (an egg and sperm) fuse to form a zygote.

Darya [45]

Answer:

0.382g

Explanation:

Step 1: Write the reduction half-reaction

Al³⁺(aq) + 3 e⁻ ⇒ Al(s)

Step 2: Calculate the mass of Al produced when a current of 100. A passes through the cell for 41.0 s

We will use the following relationships.

1 A = 1 C/s

1 mole of electrons has a charge of 96486 C (Faraday's constant)

1 mole of Al is produced when 3 moles of electrons pass through the cell.

The molar mass of Al is 26.98 g/mol.

The mass of Al produced is:

$41.0s \times \frac{100C}{s} \times \frac{1mole^{-} }{96486C} \times \frac{1molAl}{3mole^{-} } \times \frac{26.98gAl}{1molAl} = 0.382gAl$
