The possible reactants could be sodium thiosulfate and silver nitrate, forming a yellow precipitate of silver sulfide. Another possibility is mixing potassium chromate and lead(II) nitrate, forming a yellow precipitate of lead chromate.

No. Some detergents contain bleach, which can pull the color out of some clothes. If a detergent contains bleach it must say so on the label, so if it does not say bleach on the label it is most likely color-safe. Many labels now specifically say that they are "color-safe" for "all colors", so look for those words.

Yes, it is possible for two parents with hazel green eyes and blue eyes to have a brown-eyed baby. Eye color is determined by multiple genes, so there is a chance that the combination of genes from both parents could result in a child with brown eyes.

Fast colors are dyes or pigments that are resistant to fading when exposed to different conditions such as sunlight, washing, or dry-cleaning. These colors maintain their intensity and brightness over time, making them durable and long-lasting. Fast colors are commonly used in textiles, paints, inks, and other products where color stability is important.

there are 7 colours in a rainbow

Red, orange, green, Yellow, indago, Blue and violet

thanks!!

Isaac Newton used a triangular prism to separate white light into its spectrum of colors. When white light passes through the prism, the different wavelengths of light are refracted by different angles, causing them to spread out and create the rainbow of colors.

... reflected, and perceived by passersby.

The fill color icon is used to change the color of the background or fill of an object, shape, or text in a document, spreadsheet, or graphic design program. It allows you to customize the appearance of your content to make it more visually appealing or to highlight important information.

Red algae are red because of the presence of the pigment phycoerythrin; this pigment reflects red light and absorbs blue light. Because blue light penetrates water to a greater depth than light of longer wavelengths, these pigments allow red algae to photosynthesize and live at somewhat greater depths than most other "algae". Some rhodophytes have very little phycoerythrin, and may appear green or bluish from the chlorophyll and other pigments present in them.

I believe that this is true and this needs to be corrected if it is not. White light is the effect of the combination of ALL frequencies of visible light, it is not the combination of a few specific frequencies of light. You can come close to producing white light even using rather crude means, by taking a child's construction paper colored red orange yellow green and blue and arranging roughly equally sized wedges of them onto a spinning disk. But actual white light is ALL frequencies blended together. It is roughly analogous to static or 'white noise', which gets its name from the concept.

A prism, for example, will not break sunlight into extremely discrete narrow bands of color, but will give an even spread of light varying in color from red to dark blue.

Cattails have brown seed heads and stalks, while their leaves are green.

basicly you should be able to put a light brown dye over it and it should be the color you want because your hair color depends on all the colors in it. if you have black hair it also has brown red and blond in it, brown also has red and blond, red is just that and blond & blond is just that. so you can just go from red to brown you shouldn't need to do anything else but if you wanted to go from blond to brown you would have to use a red base other wise you wont have the red to make the brown

It might be possible to ferment the sugars in sodas. Generally to make alcohol, you need yeast, sugars and time. Grape juice is fermented to give wine. Most fruit and vegetables can be fermented but the fructose syrup inside the soda would not be enough to get much alcohol.

Onyx is a natural stone and cannot be dyed like fabric. Instead, it is often treated with heat or chemicals to enhance or alter its color. However, the process can be complex and may require professional expertise to achieve the desired results.

ROY G BIV is associated with visible light, which refers to the light that is visible to the human eye and contains all the colors of the rainbow in the electromagnetic spectrum.

Kate Bosworth has a condition called heterochromia, which causes her to have one blue eye and one brown eye. This is a rare genetic trait that results in a person having two different colored eyes.

There had to be blue eyes within your genealogy. You need two recessive genes to produce blue eyes. Still, the bottom line is, it is very possible. There are individuals in my family that have blue eyes with parents that have brown eyes.

Litmus paper: red color in acidic solutions and blue color in basic solutions.
Phenolphthalein: no color in acidic solutions.

There are two things going on here. The first thing is that if you look at most "black light" bulbs when they're on you'll see they're not actually black, they're purple. When you shine a purple light on a white object, it looks purple. This is the dull purple color that some white objects have under black light. Many white articles of clothing, though, shine a fairly bright purple (in many cases it's more of a bluish color). Underwear is particularly good at this (which may be either embarrassing or exactly the effect you were going for, depending on your personal sense of fashion). In this case, what's happening is: laundering. Many fabrics yellow slightly over time, making them appear dingy. To counteract this, detergent (and sometimes bleach) manufacturers include "whiteners" in their formula. These work not by removing the yellow, but by adding blue... a fluorescent compound is included which raises the intensity in the blue region of the spectrum, and when you mix blue light with yellow light you get what your eye perceives as white. Under "black light" these fluorescent compounds go nuts, and since the visible light level is pretty low, the blue light they emit can be clearly seen, in many cases even if there's another layer of clothing on top of the white ones.

The answer is red.

ummm.. yes, at the long wavelength end, heading for infra-red.

The red litmus paper dipped into household ammonia will turn blue. This is because ammonia is a base and reacts with the acidic red litmus paper, causing it to change color to blue.
