Both acids and bases produce a part of a water molecule. Bases dissociate hydroxide (–OH) ions and acids, hydrogen (H+) ions that when combined form water. Both are also very corrosive when they are strong enough that they fully dissociate in water.
Answer:
The new pressure is 40 atm
Explanation:
Step 1: Data given
Volume of the gas = 20.0 L
Pressure of the gas = 10.0 atm
The volume decreases to 5.0 L
Step 2: Calculate the new pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure of the gas = 10.0 atm
⇒with V1 = the initial volume of the gas = 20.0 L
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the decreased volume = 5.0 L
10.0 atm * 20.0 L = P2 * 5.0 L
P2 = 200 / 5.0
P2 = 40 atm
Since the volume is 4x smaller, the pressure is 4x more
The new pressure is 40 atm
Answer:
The data will be error free and more correct.
Explanation:
The data will show no error while testing the adsorptive properties of a new material if no centrifuge method is not used because there is no need for centrifuge method. For determining the adsorptive properties of a new material, we can measure the data after dissolving . Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface while on the other hand, Centrifugation is the process where a mixture is separated from one another through fast spinning. so for determining the adsorptive properties, no centrifugation process is required and we get the correct data without centrifugation.
Answer:
The difference in electronegativity between fluorine (4.0) and hydrogen (2.1) is quite high, so the shared electrons spend much more time in the vicinity of the fluorine atom. As a result, fluorine carries a partial negative charge in this molecule, whereas hydrogen carries a partial positive charge
