Answer:
The answer is
<h2>6.1 cm³</h2>
Explanation:
To find the volume in cm³ we must first find the volume of the rock .
To find the volume of the rock , subtract the initial volume of water from the final volume of the water when the rock was dropped in it
That's
volume = final volume of water - initial volume of water
volume of rock = 47.6 mL - 41.5 mL
= 6.1 mL
Next we use the conversion
<h3>1 mL = 1 cm³</h3>
If 1 mL = 1 cm³
Then 6.1 mL = 6.1 cm³
Hope this helps you
Answer:
The volume of feedstock needed to mantain an organic load rate of 2 kgVS/day is 0.055 m3/day of feedstock.
The HRT is 20.6 days.
Explanation:
First, we calculate how many kg is 1 m3 of feedstock. We know the density, so we can calculate the mass:
If the VS are 6% in weight,
The volume per day needed to feed 2 kg of VS/day is:
The HRT depends on the volume of the tank and the flow. Its equation is
Ionic compounds are formed by the bonding of non-metals to metals. Because inonic bonds involve electon transfer, the result is a mixture of ions; positive and negative, following the laws of electrostatics, like charges attract. These ions then form a giant structure (lattice) of ionic bonds and it is because of this that ionic compounds are solids (unless dissolved in water) and have extremely high melting and boling temparatures. In additions, beucase of the fixed placement of ions (charged particles) in a lattice, in the solid state ionic compounds don't conduct electricity very well but if dissolved in water (aqueous solution) the ions are free to move and carry a current.
It is important to make sure the solvent is level and not at an angle so you do not get an angled solvent front.
