The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.

Explanation:

As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.

Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.

Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.

Mercury Hg is less reactive than Hydrogen

A fluorine atom has 9 positive charge,9 negative charges and a mass of 19. Describe the structure of its atom.

Tanya [424]

The atomic structure of the atom contains 9 positively charged particles (protons) and 10 neutrally charged particles (neutrons) in the center of the atom in a clump called the nucleus. Those 9 negatively charged particles (electrons) are moving around outside of the nucleus.
There are 10 neutral charges, because the mass of 19 comes from the number of neutral charges plus the number of positive charges.
To calculate the number of neutral charges, subtract the positive charges from the mass (19 - 9), and you get the number of neutral charges (10).

How many half-lives would something have gone through if you had 75% daughter product and 25% parent?

levacccp [35]

Answer:

Two Half-lives

Explanation:

Let number of Parent nuclei Initially present be X,

Then, finally $\frac{X}{4}$ Parent nuclei Will remain with $\frac{3X}{4}$ daughter nuclei.
