How many moles of Ga are there in 80.3 grams of Ga ? moles

Chemistry
1 answer:
Elenna [48]3 years ago
5 0
Okay so I think to approach this problem you would do some sort of unit conversion and I think it would look like this:

80.3g x 1mol
————. = about 1.15
69.723g of Ga

Ethanol is a common laboratory solvent and has a density of 0.789 g/ml. What is the mass, in grams, of 125 ml of ethanol?
olga55 [171]

The density of a material is its unique property by which a unknown material can be identified and also the impurity (if present) in a material can be concluded. Mathematically the density can be expressed as-\frac{mass}{volume}. Thus from the mathematical expression we can say that the density is the mass per unit volume of a material. Here the density of ethanol is given 0.789 g/mL. Thus the weight of the 1 mL ethanol is 0.789g. Thus the weight of the 125 mL of ethanol will be (125×0.789) = 98.625 g.

What is the only part of an atom that cannot change (either protons, neutrons, or electrons)?
d1i1m1o1n [39]
The number of protons never changes in an atom. More electrons means a negative charge and fewer means a positive charge. Once an atom has an electrical charge it is called an ion. In an ion the atomic number and atomic mass do not change from the original.

1. Consider the reaction: N2 (g) + O2 (g)  2NO (g) + Cl2 (g) A reaction mixture at 400 C has the following composition: [NO] =
Olegator [25]

Answer:

The reaction is not at the equilibrium, we have more products than reactants.

Explanation:

Step 1: Data given

Temperature = 400 °C

When Q=K, this means the system is at equilibrium. There will not be a shift to either the left or the right.

When Q<K,it means we have more reactants than products. The system will, as reaction, make more products, this will cause the equilibrium to move to the right.

When Q>K,it means we have more products than reactants. The system will, as reaction, make less products and more reactants, this will cause the equilibrium to move to the left.

[NO] = 0.01 M

[N2] = 0.001 M

[O2] = 0.001 M

Kc = 0.0156

Step 2: The balanced equation

N2 (g) + O2 (g) ⇆ 2NO (g) + Cl2 (g)

Step 3: Calculate Q

Q = [NO]²/[N2][O2]

Q = 0.01²/(0.01*0.001)

Q = 10

Q>>Kc

This means we have more products than reactants. The system will, as reaction, make less products and more reactants, this will cause the equilibrium to move to the left.

The reaction is not at the equilibrium, we have more products than reactants.
