Which describes one feature of the image formed by a plane mirror? real image larger than the object upside down right side up.

svlad2 [7]

The feature of the image formed by a plane mirror is right side up.

The correct option is D.

<h3>What is an image formed by a plane mirror?</h3>

A plane mirror has a flat and reflective surface.

If a light strike on plane mirror, the angle of reflection is equal to the angle of incident.

A plane mirror's image is virtual, erect, and the same size as the item.

It gives the impression that the object and its image are equidistant from the mirror.

Thus, the correct option is D. right side up.

Drag each Moon phase to the correct location on the image.

ruslelena [56]

The correct order of the given moon phases starting with new moon is new Moon, waxing crescent Moon, first quarter Moon, waxing gibbous Moon, full Moon, waning gibbous Moon, last quarter Moon.

<h3>What are Moon phases?</h3>

This cycle has been divided into four primary Moon phases: New Moon, First Quarter, Full Moon, and Last Quarter. Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent are the four secondary phases.

The missing image of the question is attached at the last.

The correct order of the given moon phases starting with new moon is new Moon, waxing crescent Moon, first quarter Moon, waxing gibbous Moon, full Moon, waning gibbous Moon, last quarter Moon.

Thus, this way the lunar phases can be placed in the correct order.

The pKa for the side chain of histidine is 6.0. What is the ratio of the deprotonated imidazole side chain to the protonated sid

Solnce55 [7]

Answer:

When the pKa is 6.0, we can determine the fraction of protonated H is by:

pH = pKa + log [A]/[HA]

Where

A = Deprotonated imidazole side

HA = Protonated side

Given, pH = 5.0

5 = 6 + log [A]/[HA]

log [A]/[HA] = -1 (take antilog of both side)

[A]/[HA] = 0.1

The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 0.1

Given, pH = 7.5

7.5 = 6 + log [A]/[HA]

log [A]/[HA] = 1.5 (take antilog of both sides)

[A]/[HA] = 31.62

The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 31.62
