Answer:

See explanation

Explanation:

FeCl3 +3 NaOH →3 NaCl + Fe(OH)3

One mole of ferric chloride reacts with three moles of sodium hydroxide to yield three moles of sodium chloride and one mole of ferric hydroxide. The reaction demonstrate the law of conservation of mass because the total mass of reactants equals the total masses of products formed.

b) neutralization reaction

c) lead is lower than zinc in the activity series of metals but calcium is higher than zinc hence zinc cannot displace calcium but it can displace lead.

d) the half life is 21 hours

e) it will take 320g grams 21 hours to remain 160g

It will take 160g 42 hours to remain 80g

It will take 80g 63 hours to remain 40g

It will take 40g 84 hours to remain 20g

It will take 20g 105 hours to remain 10g

It will take 10g 126 hours to remain 5g

It will take 5g 147 hours to remain 2.5g

What will be the volume occupied by 2.5 moles of nitrogen gas exerting 1.75 atm of pressure at 475K?
Marina86 [1]

Answer:

THE VOLUME OF THE NITROGEN GAS AT 2.5  MOLES , 1.75 ATM AND 475 K IS 55.64 L

Explanation:

Using the ideal gas equation

PV = nRT

P = 1.75 atm

n = 2.5 moles

T = 475 K

R = 0.082 L atm/mol K

V = unknown

Substituting the variables into the equation we have:

V = nRT / P

V = 2.5 * 0.082 * 475 / 1.75

V = 97.375 / 1.75

V = 55.64 L

The volume of the 2.5 moles of nitrogen gas exerted by 1.75 atm at 475 K is 55.64 L
