Answer:
1 mole of each element have same number of particles. i.e. 6.02×10^23
Explanation:
So both have same atoms
Answer:
17.83M
Explanation:
Given parameters:
Mass of KCO₂ = 1.5kg
Volume of water = 850mL
Unknown:
Molarity of solution = ?
Solution:
Molarity is defined as the number of moles per unit volume. It is the number of moles of solute in a given volume of solution.
Molarity = 
Number of moles of solute = 
Molar mass of KCO₂ = 39 + 12 + 3(16) = 99g/mol
Number of moles = 
= 15.15moles
850mL : gives 0.85L
Molarity = 
= 17.83M
Answer:
The answer to your question is letter d. Sr(ClO₃)₂
Explanation:
Data
Reactants HClO₃ and Sr(OH)₂
This is a neutralization reaction because the reactants are a base (Sr(OH)₂) and an acid (HClO₃).
The products in a neutralization reaction are always water and a salt.
Balanced chemical reaction
Sr(OH)₂ + HClO₃ ⇒ H₂O + Sr(ClO₃)₂
The mass of GeCl4 that would be formed will be 1.51 g
<h3>Stoichiometric calculations</h3>
From the balanced equation of the reaction:
Ge (s) + 2Cl2 (g) →GeCl4
The mole ratio of Ge and Cl2 is 1:2.
Mole of 1.0 g Ge: 1/72.64
= 0.01377 mole
Mole of 1.0 g Cl2 = 1/71
= 0.01408 mole
Thus, Cl2 is limiting.
Mole ratio of Cl2 and GeCl4 = 2:1
Equivalent mole of GeCl4 = 0.01408/2
= 0.0070 mole
Mass of 0.0070 mole GeCl4 = 0.0070 x 214.4
= 1.51 g

Option A. Exothermic reactions RELEASE energy, so the potential energy of the products will be less than the energy of the reactants.
