An object with a height of 0.3 meter is placed at a distance of 0.4 meter from a concave spherical mirror. An image with a heigh
Sophie [7]

We can use the magnification equation for this problem.

Magnification equation:

<em>hi/h0 = di/d0</em>

Where in <em>hi </em>: image size, <em>h0</em> : object size, <em>di </em>: image distance, <em>d0 </em>: object distance from mirror

So plugging in the given variables we will have the corresponding equation

0.1 m / 0.3 m = <em>di / </em>0.4 m

<em>di</em> = 0.1333333m

The generated image of the object is located 0.13 meters or 13 cm away from the mirror

Question 3) A 1.00 L buffer solution is 0.250 M in HF and 0.250 M in LiF. Calculate the pH of the solution after the addition of
Masja [62]

The pH of the solution after adding 0.150 moles of solid LiF is 3.84

<u>Explanation:</u>

We have the chemical equation,

HF (aq)+NaOH(aq)->NaF(aq)+H2O

To find how many moles have been used in this

c= n/V=> n= c.V

nHF=0.250 M⋅1.5 L=0.375 moles HF

Simillarly

nF=0.250 M⋅1.5 L=0.375 moles F

nHF=0.375 moles - 0.250 moles=0.125 moles

nF=0.375 moles+0.250 moles=0.625 moles

[HF]=0.125 moles/1.5 L=0.0834 M

[F−]=0.625 moles/1.5 L=0.4167 M

To determine the problem using the Henderson - Hasselbalch equation

pH=pKa+log ([conjugate base/[weak acid])

Find the value of Ka

pKa=−log(Ka)

pH=−log(Ka) +log([F−]/[HF]

pH= -log(3.5 x 10 ^4)+log(0.4167 M/0.0834 M)

pH=-log(3.5 x 10 ^4)+log(4.996)

pH= -4.54+0.698

pH=-(-3.84)

pH=3.84

The pH of the solution after adding 0.150 moles of solid LiF is 3.84

Nitrogen-fixing bacteria live in protective nodules (bumps) on the roots of some plants. These bacteria are able to convert gase
Vsevolod [243]
I believe it is A because the plant is offering protection while the bacteria is converting it in to nitrogen that the plant can use!
