Explanation:
1) A balanced equation for the reaction.
2) The name of the soluble slat produced by reaction between magnesium and hydrochloric acid is magnesium chloride.
Magnesium chloride =
3)Yes, chemical change has been taking.
This is because rearrangement of atom is taking place which resulted in formation of hydrogen gas amd magnesium chloride.
4) Moles of hydrogen gas produced = 2 mole
According to reaction, 1 mole of hydrogen gas is obtained from 2 moles of HCl.
Then 2 moles of hydrogen gas will be obtained form:
of HCl
4 moles of acid has reacted.
Idk it’s making me answer a question in order to get help on my own
C12 is to 642 and stop will be a28 so 642+a28=1879ab
Answer:
see answer
Explanation:
DO the postulates of Daltons atomic theory explain the law of conservation of mass and the law of constant composition.
<h2>
Dalton's Atomic Theory Postulates
</h2>
1. Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed or divided any further.
2. All atoms of a single pure element are the same in size and mass
3. Atoms of different elements vary from each other in size and mass.
4. Compounds are produced through different simple whole-number combinations of atoms to produce molecules.
5. Anywhere a compound exists, it will have the same atoms in the same ratio.
6. A chemical reaction between compounds is a re-arrangement of atoms
The law of conservation of mass is shown in 2, 4. and 5.
The law of constant co,position is shown in 2, 4, 5, and 6
