This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

I looked this up but hope it helps!

What is the volume in mL of a cube with each side 80mm long ?

dem82 [27]

<h3>Answer:</h3>

512 mL

<h3>Explanation:</h3>

We are given;

A cube with a side 80 mm long or 8 cm long

We are required to calculate the volume;

Volume refers to the amount of space an object occupies.
To calculate the volume of a cube we get the cube of its side;

That is, volume of the cube = l³

Therefore;

Volume = (8 cm)³

= 512 cm³

But; 1 cm³ = 1 mL

Therefore, the volume of the cube in mL is 512 mL

The value of the equilibrium constant for a reaction is 2.65 x 10-6 at 35° Calculate the value of LaTeX: \DeltaΔG°rxn.

stealth61 [152]

Answer:

The answer is "33.95 $\bold{ \frac{kj}{mol}}\\$ ".

Explanation:

Formula:

$\bigtriangleup G_0= -R \times T l_n \times K_{eq}\\$

where

$K_{eq} = \text{equilibrium constant}\\$

Given value:

$T =35^{\circ} C\\$

convert temperature celsius (°C) to Kelvin (K):

$= (273+45) \ kelvin \\\\= 318 \ Kelvin \\\\= 318 \ K$

$R = 8.314 \ \ \frac{J}{ mol \cdot K}$

$\bigtriangleup G_0= -(8.314 ) \times 31.8 \times l_n (2.65\times 10^{-6})\\$

$=-(8.314 ) \times 31.8T l_n \times (2.65\times 10^{-6})\\\\$

After solving the value it will give:

= 33.95 $\bold{ \frac{kj}{mol}}\\$
