Salsk061 [2.6K]2 years ago
7 0

Answer:

<h2>8.13 mL</h2>

Explanation:

The required volume can be found by using the formula for Boyle's law

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

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

From the question we have

V_2 =  \frac{6.5 \times 1.25}{1}  = 6.5 \times 1.25 \\  = 8.125

We have the final answer as

<h3>8.13 mL</h3>

Hope this helps you

How does a conjugate acid differ from its conjugate base?
inna [77]

The conjugate acid is differ from its conjugate base as, conjugate acid is formed by strong base whereas conjugate base is formed by strong acid.

conjugate base is differ from conjugate acids by the presence of the proton. The conjugate acid is formed when proton is added to the bases whereas conjugate bases is formed when proton is released by the acids.

Example of corrugate acids are given below.

NH_{3} → NH_{2} ^{-} +H^{+}

In the above example  NH_{2} ^{-} is conjugate acids.

How many of the following molecules are polar? Pcl5 cos xeo3 sebr2
klasskru [66]

Answer:

<em>Three (3) of the molecules are polar: </em>CoS,<em> </em>XeO_{3},<em> </em>SeBr_{2}<em>.</em>

Explanation:

Polar substances have their elements held together by a covalent bond that contain partially positive and negative charges, which results in a difference in the charges' electronegativity difference (usually ranging between 0.4 and 0.7).

  • PCl5 is <u>non-polar</u> with a symmetric geometry
  • CoS is <u>polar</u>
  • XeO3 is <u>polar</u>, with a trigonal pyramidal molecular geometric
  • SeBr2 is <u>polar</u> as the difference their electronegativity is about ).5

what is the molarity of an HCI solution if 25.0 ml of 0.185 M NaOH is required to neutralize 0.0200 L of HCI?​
butalik [34]

Answer:

Molarity of HCl solution = 0.25 M

Explanation:

Given data:

Volume of NaOH= V₁ = 25.0 mL (25/1000 = 0.025 L)

Molarity of NaOH solution=M₁ = 0.185 M

Volume of HCl solution = V₂ = 0.0200 L

Molarity of HCl solution =  M₂= ?

Solution:

M₁V₁   =  M₂V₂

0.185 M ×0.025 L =  M₂ × 0.0200 L

M₂  = 0.185 M ×0.025 L / 0.0200 L

M₂  = 0.005M.L /0.0200 L

M₂  =  0.25 M
