Answer:
Yes, Mass is conserved.
Explanation:
Every chemical reactions obey the law of conservation of mass. The law of conservation of mass states that in chemical reactions, mass is always constant.
Equation:
2Na + Cl₂ → 2NaCl
From the equation above, one can observe that the reaction started using 2 atoms of Na and it produced 2 atoms of the same element in NaCl. A molecule of Cl produced 2 atoms of Cl in the NaCl
Design a simple experiment to support your answer:
Aim: To demonstrate the law of conservation of mass
One Na atom weighs 23g
Two Na atom will weigh 2 x 23 = 46g
1 atom of Cl is 35.5g
1 molecule of Cl containing two atoms of Cl will weigh 2 x 35.5 = 71g
Total mass of reactants = mass of 2Na + 1Cl₂ = (46 + 71)g = 117g
On the product side, Mass of 1 NaCl = 23+ 35.5 = 58.5g
Two moles of NaCl will give 2 x 58.5g = 117g
Since the mass on both side is the same, one can say mass is conserved.
<span>the attraction to the positive end of a water molecule.hope this helps you</span>
Answer:
Al+3
Explanation:
Ion is a positively or negatively charged species. A neutral species does not carry any charge.
here only Al has +3 charge. So it is an ion.
Molar mass:
KOH = 56.0 g/mol
Number of moles of KOH :
5.93 / 36.5 => 0.1624 moles
<span>KOH + HCl = KCl + H₂O
</span>
1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?
moles HCl = 0.1624 x 1 / 1
= 0.1624 moles of HCl
V ( HCl ) = moles / molarity
V(HCl) = 0.1624 / 0.183
V (HCl) = 0.887 L x 1000 = 887 mL
hope this helps!
When all coefficients are multiplied by a single factor, The following actions are allowed while balancing a chemical equation: adding coefficients in front of reactant and product formulations.
<h3>How can chemical equations maintain balance?</h3>
Equal numbers and types of each atom appear on both sides of balanced chemical equations . Coefficients in a balanced equation must be the simplest whole number ratio. Chemical processes always retain mass.
<h3>What is a simple chemical equation?</h3>
A chemical equation is a symbol- and formula-based symbolic representation of a chemical reaction, with the reactant entities supplied on the left side and the product entities given on the right.
