eaving the proton to dissociate. The larger electronegative oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate. The smaller electropositive oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate. The larger electropositive oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate. Water does not ionize well.

Answer:

The larger electronegative oxygen atom strips the electron from one of its hydrogen atoms, leaving the proton to dissociate.

Explanation:

Water is a molecule composed of hydrogen and oxygen atoms that forms a covalent bond i.e. share electrons. However, due to the fact that the oxygen atom in a water molecule is more electronegative than the hydrogen molecule, it tends to draw electrons towards itself, leaving the hydrogen atom more positive. This causes the POLARITY of water.

To ionize means for the atoms of a compound to dissociate into electrically charged ions (positive and negative) in an aqeous solution. Water is able to ionize because the more electronegative oxygen atom draws the electron from one of its hydrogen atoms, leaving the proton (H+) to dissociate.

Ok we can use boyle’s law (stating that P is proportional to V) to make the equation (P1V1) =(P2V2).
once we’ve done this, we can plug in the numbers:
(800•500) = (200•V2)
and then we get that
V2= 2000 ml

hope this helps!! :)

A doctor's Order is 0.125 g of ampicillin. The liquid suspension on hand contains 250 mg/s. How many milliliters (mL) of the sus
Molodets [167]

Answer:

c) 2.5 mL

Explanation:

Solution

Doctors order = 0.125g

and

The liquid suspension concentration = 250 mg/5ml

= 0.250g/5ml

Or 0.05g/ml

Amount of ml of suspension required = 0.125g/(0.05g/ml) = 2.5ml

If 72.5 grams of calcium metal (Ca) react with 65.0 grams of oxygen gas (O2) in a synthesis reaction, how many grams of the exce
Natali5045456 [20]
2Ca + O2 = 2CaO
First, determine which is the excess reactant
72.5 g Ca (1 mol) =1.8089725036
(40.078 g)

65 g O2 (1 mol) =2.0313769611
(15.999g × 2)
Since the ratio of to O2 is 2:1 in the balanced reaction, divide Ca's molar mass by 2 to get 0.9044862518. this isn't necessary because Ca is already obviously the limiting reactant. therefore, O2 is the excess reactant.

Now do the stoichiometry
72.5 g Ca (1 mol Ca) (1 mol O2)
(40.078 g Ca)(2 mol Ca)(31.998g O2)

=0.0282669621 g of O2 left over
