I’m thinking that it is probably Antacid tablet’s neutralize stomach acid. Since it would be expected for a purple thing to be purple in all states of matter that’s not weird at all, the helium one just seems like a throw in like why is that a chemical property, water freezing at it’s freezing point is normal, the only one left is the tablet one.

What volume, in milliliters, of a 0.997 M KOH solution is needed to neutralize 30.0 mL of 0.0400 M HCl?
deff fn [24]

Answer:

1.2 mL

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated:

HCl + KOH —> KCl + H₂O

From the balanced equation,

Mole ratio of the acid, HCl (nₐ) = 1

Mole ratio of base, KOH (n₆) = 1

Finally, we shall determine the volume of the base, KOH needed to neutralize the acid, HCl as follow:

Molarity of base, KOH (M₆) = 0.997 M

Volume of acid, HCl (Vₐ) = 30 mL

Molarity of acid, HCl (Mₐ) = 0.0400 M

Volume of base, KOH (V₆) =?

MₐVₐ / M₆V₆ = nₐ/n₆

0.04 × 30 / 0.997 × V₆ = 1/1

1.2 / 0.997 × V₆ = 1

Cross multiply

0.997 × V₆ = 1.2

Divide both side by 0.997

V₆ = 1.2 / 0.997

V₆ = 1.2 mL

Thus, the volume of the base, KOH needed to neutralize the acid is 1.2 mL.

you are riding in a train that is traveling at a speed of 120km/h how long will it take to travel 950km
muminat

The time take for the train to travel 950 Km is 7.92 h

<h3>What is speed? </h3>

Speed is the distance travelled per unit. Mathematically, it can be expressed as:

Speed = distance / time

With the above formula, we can determine the time. Details below:

<h3>How to determine the time</h3>

The time taken for the train t travel 950 Km can be obtained as follow:

  • Speed = 120 Km/h
  • Distance = 950 Km
  • Time =?

Speed = distance / time

120= 950 / time

Cross multiply

120 × time = 950

Divide both side by 120

Time = 950 / 120

Time = 7.92 h

Given a stock solution of 0.128 m bromide, solve for the bromide concentration obtained by diluting a 450 µl aliquot to the mark
Vikki [24]

Hey there!

Stock solution:

Concentracion bromide = 0.128 M

initial solution in volumetric flask =  450 µl

So , moles of bromide present:

450  µl in liters :

1 µl  =   = 1*10⁻⁶ liters

450 * ( 1*10⁻⁶ )  = 0.00045

0.128 * 0.00045 =>  57.6 * 10⁻⁶ moles

Now volume final is 25 mL , in liters : 0.025 L ou 25*10⁻³

so  new  bromide concentration:

57.6*10⁻⁶ / 25*10⁻³=> 2.304*10⁻³ M
