Answer:

The answer is : His analysis of the composition is not correct.

Explanation:

The answer is actually an asteroid (if there was that option), so that marks out A and D. Also he used the word crater correctly so that marks out C, so the answer must be B: His analysis of the composition is not correct.

I really hope this helps!

Answer:

He actually found a meteoroid.

Explanation:

  • When an Asteroid that is enter the planet in the atmosphere and there in the space planets debris.
  • The streak of light seen in atmosphere when the meteoroid burns up on its way through the atmosphere is a meteor.
  • The meteoroid which lands up on the surface of the planet is known as meteorite.
  • So, when a scientist found a piece of stone in a crater, He actually found a meteoroid.

A formic acid buffer solution contains 0. 20 m h c o o h hcooh and 0. 24 m h c o o − hcoox−. the pka of formic acid is 3. 75. wh
irina1246 [14]

A buffer solution contains an equivalent amount of acid and base. The pH of the solution with an acid dissociation constant (pKa) value of 3.75 is 3.82.

<h3>What is pH?</h3>

The amount of hydrogen or the proton ion in the solution is expressed by the pH. It is given by the sum of pKa and the log of the concentration of acid and bases.

Given,

Concentration of salt [HCOO⁻] = 0.24 M

Concentration of acid [HCOOH] = 0.20 M

The acid dissociation constant (pKa) = 3.75

pH is calculated from the Hendersons equation as,

pH = pKa + log [salt] ÷ [acid]

pH = 3.75 + log [0.24] ÷ [0.20]

= 3.75 + log (1.2)

= 3.75 + 0.079

= 3.82

Therefore, 3.82 is the pH of the buffer.

When 85 L of gas at 1.376 atm has its pressure changed to 0.154 atm, what is the new volume?
igor_vitrenko [27]

Answer:

<h2>759.48 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{85 \times 1.376}{0.154}  =  \frac{116.96}{0.154}  \\  = 759.480519...

We have the final answer as

<h3>759.48 L</h3>

Hope this helps you
