Answer;
A. atoms are indivisible.
Dalton incorporated the law of conversation of mass into his atomic theory by asserting that atoms are indivisible.
Explanation;
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
-According to Dalton; Elements are made of extremely small particles called atoms. Atoms of a given element are identical in size, mass and other properties; atoms of different elements differ in size, mass and other properties. Atoms cannot be subdivided, created or destroyed.
A.
H20 and OH are a conjugate acid-base pair.
Answer:
1,42M
Explanation:
Molar concentration is given in moles of solute per liter o solution. Assuming you have 100g of solution:
10g KCl × (1mol / 74,55g) = <em>0,134 moles of KCl</em>
As you have 100g of solution:
100g × (1mL / 1,06g) × (1L / 1000mL) = <em>0,0943L</em>
<em> </em>
That means molar concentration is:
0,134 moles of KCl / 0,0943L = <em>1,42M</em>
<em></em>
I hope it helps!
