Answer from: chickennuggets0621

This is not a chemical change

Explanation:

The dark green solution mixed with the water, but the water is still water. There were no bubbles, smell, temperature change, or any other signs of a chemical change

Option (1).

Explanation:

Precipitation reaction may be defined as the chemical reaction in which an insoluble substance called precipitate forms at the end of the reaction. The ions are displaced twice during the precipitation reaction.

The mixing of two clear liquids forms a white substance. This substance is an insoluble precipitate that forms by the chemical combination of the reactants. The two reactants have undergone the chemical change that leads to the formation of the precipitate.

Answer from: Quest

If a hydrogen atom is neutral, it must also have one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

Answer from: Quest

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. $hbr$ completely dissociates to $h^+$ and $br-$ ions. a is incorrect because $h_2s$ does not fully ionize to $h^+$ and $hs^-$ ions and some remain as the compound $h_2s$ . c and d are incorrect because, $li_2o$ and $libr$ do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise, if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both $li_2o$ and $libr$ have a complete octet so can not accept any electrons which disqualifies them as acids.
