How many moles of neon (Ne) gas have a volume of 4.5L and a pressure of 2.1 atm at 302 K
Montano1993 [528]

Answer:

0.3811 mol.

Explanation:

  • To calculate the no. of moles of a gas, we can use the general law of ideal gas: <em>PV = nRT</em>.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

∵ P = 2.1 atm, V = 4.5 L, T = 302 K, R = 0.0821 L.atm/mol.K.

<em>∴ n = PV/RT </em>= (2.1 atm)(4.5 L)/(0.0821 L.atm/mol.K)(302.0 K) = <em>0.3811 mol.</em>

Which molecule, when added to a solution, would give the solution the highest pH
kondor19780726 [428]

Potassium Hydroxide (KOH) when added to the solution would give the highest pH

Explanation:

Bases or Alkali are associated with high pH while Acidic substances are represented by lower pH value.

In the given option

HCl- is a strong acid hence would have pH less than 7

H2SO4- also an acid with a pH less than 7

KOH- base with a pH higher than 7

H20-neutral compound with pH as 7

KOH is a very strong base and dissociates in aqueous solution to give it's corresponding metallic ion and hydroxyl ions (OH-) which are characteristic property of any base.

Neutralization is a process that occurs whenever an acid reacts with a base in the mole ratios specified by the balanced equatio
labwork [276]
The factors that can determine the outcome of a "neutralization reaction" include:
__________________________________________________________
1) temperature; 

2) concentration (of the solution); 

3) type of acid used;

4) type of alkali used;

5) type of reaction; 
     (e.g. whether the reaction is "endothermic" or "exothermic");
