Answer:
where are the statements??
Explanation:
Answer:
The answer is true
Explanation:
Products in chemical reactions are rearranged during the reaction, the atoms end up in different combinations in the products. This makes the product new substances that are chemically different than the reactants
Answer:
Sodium iodide NaI
Magnesium chloride MgCl₂
Explanation:
Silicon dioxide SiO₂ it is not soluble in water, so it can not be recrystallized from water, it is a white solid and the boiling point is 2230 °C. This one is not the unknown solid.
Sodium iodide NaI it is soluble in water, it has a white color and the boiling point is 1304 °C
. This can be the unknown solid.
Magnesium chloride MgCl₂ is soluble in water, it have a white color and the boiling point is 1,412 °C
. This can be the unknown solid.
Phosphorus tribromide PBr₃ is will start a hydrolysis reaction in water, it is a colorless liquid and it has a boiling point of 173 °C. This one is not the unknown solid.
Answer:
H20
water (the chemical symbol, as used in non-specific contacts. 8 equals hydrogen equals oxygen and two elements in hydrogen therefore is known as H2O .
H202
hydrogen peroxide equals hydrogen peroxide is the chemical compound with formula h202. And it's your form, it is very pale blue liquid, slightly more vicious than water. It is used as an oxidizer, bleaching agent, and antiseptic .
Co=
carbon monoxide, carbon monoxide is colorless, odorless, and tasteless flammable gas that is slightly less dense than air. Formula equals Co
