Answer:

10 g/cm3

Explanation:

The density is equal to mass/volume

so Mass is 80g

and volume is 2*3=8

so density=80/8=10g/cm3

Answer:

\boxed {\boxed {\sf 10 \ g/cm^3}}

Explanation:

We are asked to find the density of a cube. The density of a substance is its mass per unit volume. The formula for calculating density is:

\rho= \frac{m}{v}

We know the mass of the cube is 80 grams. We don't know the volume of the cube, but we can calculate it using the following formula.

  • v= s^3

The side length (s) of the cube is 2 centimeters. Substitute this value into the formula.

  • v= (2 \ cm)^3
  • v= (2 \ cm)* (2 \ cm)* ( 2 \ cm)
  • v= 8 \ cm^3

Now we know the mass and volume of the cube. We can substitute the values into the density formula.

  • m= 80 g
  • v= 8 cm³

\rho= \frac{80 \ g }{8 \ cm^3}

Divide.

\rho= 10 \ g/cm^3

The density of the cube is <u>10 grams per cubic centimeter.</u>

At equilibrium, a 1.0 L reaction vessel contains 2.3 mol of Mg(OH)₂ and 0.170 mol of OH⁻. What is the equilibrium concentration
Andru [333]

The value of X for this chemical reaction is 1.65 x 10⁻⁴

<u>Explanation:</u>

Mg (OH)₂(s) <==> Mg²⁺+(aq) + 2OH₋₁(aq)  

Kc= 1.80x10⁻¹¹

KC = [Mg²⁺][OH-]²

Let us assume

Put X = [Mg²⁺] and  2x = [OH-]

1.80x10-11 = (X) (2X)²

1.80x10-11 = 4X³

X³ = 4.5x10⁻¹²

On simplifying the equation we get,

X = 1.65 x 10⁻⁴

The value of X for this chemical reaction is 1.65 x 10⁻⁴

I'm not sure what the question is asking, but the process would be considered endothermic (it absorbs heat)

Please answerrrrrrrrrrrrrrrrrrrrrrrrr
nydimaria [60]

Answer: I'm in no way like an expert but I've heard water goes from an elevated area to a lower area. So it should be arrows that start at a more elevated to less elevated. Like white to brown, and orange to yellow, and stuff like that. I hope that helped? Anyway, have a lovely day!
