The color of an opaque object is the same as the light that is
a) transmitted b) absorbed c) reflected d) all of these

reflected

A material is opaque when it does not allow light to pass through itself.

In other words:

When light illuminates an opaque object, no ray passes through it, as most of the light is reflected or absorbed by the object.

In this context, the main characteristic of this type of objects is that the color of the material depends on the light it absorbs. It means that depending on its chemical composition they can absorb certain wavelengths (colors) and reflect others.

Therefore, the color we see in an object is the light it reflects. For example, if we see a red table, this means that when light iluminates it, this table absorbed all the visible wavelengths, except the red, which is the light that is reflected and perceived by our eyes.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

d) physical means can be used to separate the components of air.
