<span>Answer: yes, when you balance a chemical reaction, you are making sure that the law of conservation of matter is obeyed.
</span>
<span /><span /><span>
Justification:
</span><span />
<span>1) When you balance a chemical reaction, you add the coefficients to make the number of atoms of each element in the left side of the equation (reactants) equal to number of atoms of the same elements in the right side (products).
</span><span />
<span>2) Since, each atom has a unique atomic mass associated, it results, necessarily, that the mass of the atoms of the reactants is equal to the mass of the atoms of the products</span>.
Answer:
molar mass is 158g and the mass of 5moles is 790g
Explanation:
this is becasuse i added the atomic mass of each of the elements in the compound and also taking note of their subscript.the i multiply the molarmass by 5 for 5moles of the compound
3 MgCl₂ + 1 Na₃P = 1 Mg₃P₂ + 6 NaCl<span>
Mg</span>₃Cl₂ = <span>Magnesium Phosphide
</span>
NaCl = Sodium <span>chloride
hope this helps!</span>
3.1 is not the same as 2.97
Answer:
This cannot be determined without knowing the actual mass of the objects.
Explanation:
its like trying to compare the letter A and letter B
