Consider the following equation in chemical equilibrium.

What type(s) of bonding would be expected for each of the following materials: a. brass (a copper-zinc alloy), b. rubber, c. bar

Lady_Fox [76]

Explanation:

Brass (a copper-zinc alloy)-The brass bond is brittle because it is a metal alloy.

Rubber-Rubber bonding is covalent.

Barium sulfide (BaS) — Bonding is primarily ionic (but some covalent) depending on the respective Ba and S positions in the periodic table.

Solid xenon-Bonding is van der Waals in solid xenon, since xenon is a noble gas.

Bronze-Bonding is metallic in that it is an alloy with silver.

Nylon-The bonding in nylon is primarily covalent with some van der Waals Forces.

Aluminum phosphide (AlP)-Aluminum phosphide (AlP) bonding is covalent in principle but it also has some ionic character.

If E=mc^2,solve for both m and c. Also, if m=80 and c=0.40 what is the value of E?

Pie

Answer:

$m = \frac{E}{c^2}$

$c = \sqrt{\frac{E}{m} }$

$E = 12.8 J$

Explanation:

Part 1: Solving for m

We are given that:

E = mc²

To solve for m, we will need to isolate the m on one side of the equation

This means that we will simply divide both sides by c²

$m = \frac{E}{c^2}$

Part 2: Solving for c

We are given that:

E = mc²

To solve for c, we will need to isolate the m on one side of the equation

This means that first we will divide both sides by m and then take square root for both sides to get the value of c

$c^2 = \frac{E}{m}\\ \\ c=\sqrt{\frac{E}{m}}$

Part 3: Solving for E

We are given that:

m = 80 and c = 0.4

To get the value of E, we will simply substitute in the given equation:

E = mc²

E = (80) × (0.4)²

E = 12.8 J

Hope this helps :)
