Answer:
The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll, while the products are glucose (sugar), oxygen and water.
Answer:
false
Explanation:
matter is anything that has mass and takes up space
this includes subatomic particles,
atoms (whcih are made of subatomic particles)
elements (whcih consis of atoms)
molecules (which are made of atoms)
compounds (which are made of molecules)
mixtures (homogeneous and heterogeneous)
and even
black holes
cheemistry is the study of the composition, properties, structure and energetic reactions of matter
Answer:
Explanation:
The compound 
is .
The reaction included are:
(because bromine is less reactive than chlorine)
But , because of hexane the solution get dilute and its color changes to orange.
Now, NaI is added and we know Br is more reactive than I.
Therefore it replace it.
Reaction: 
Purple color develop due to formation of Iodine.
In an aqueous solution of lithium chloride (LiCl), the ions present in solution are lithium cations (Li+) and chloride anions (Cl-), and the water molecules (H2O).
Lithium chloride is an ionic salt, and therefore, fully dissociates or ionizes upon dissolution in water. From the chemical formula of lithium chloride, we can say that 1 lithium ion (positively-charged) only needs 1 chloride ion (negatively charged) to form the salt. Thus, upon dissociation of 1 molecule of LiCl, only 1 lithium ion, and 1 chloride ion form.
Water is a molecule formed by covalent bonds and <u>generally</u>, does not dissociate to form ions. However, if we consider the very minor contribution of the dissociation of water, hydroxide (OH-) ions and hydronium (H3O+) ions will also be present. However for water, very few molecules, only 1 in 550 million, are dissociated at any given time. Thus, we can consider the presence of the OH- and H3O+ ions to be negligible and just identify the molecular undissociated form of water to be present.
