A technical machinist is asked to build a cubical steel tank that will hold 195 L of water. Calculate in meters the smallest pos
1 answer:
Answer:
The smallest possible inside length of the tank is m.
Explanation:
As we know that
Thus, volume of liter tank is also equal to
cubic meter
The volume of a cube is equal to , where, x is the length of the side of the cube
With the give condition,
Solving the above equation, we get -
The smallest possible inside length of the tank is m.

Hello!
In this case, since the percent water is computed by dividing the amount of water by the total mass of the hydrate; we infer we first need the molar mass of water and that of the hydrate as shown below:
Thus, the percent water is:
So we plug in to obtain:

Answer: The given statement is TRUE.
Explanation:
An equilibrium reaction is one in which rate of forward reaction is equal to the rate of backward reaction.
Equilibrium constant is defined as the ratio of the product of the concentration of products to the product of the concentration of reactants each raised to their stochiometric coefficient.
For example for the given equilibrium reaction;
Thus the given statement that in calculating the equilibrium constant for a reaction, the coefficients of the chemical equation are used as exponents for the factors in the equilibrium expression is True.
