Molecular crystals does iodine, dry ice (CO2) , ice and plastic form. It is becuase<span> is that all four are made of nonmetal elements.Which implies any compounds are made up of molecule.</span>
Answer:
hmmmm
Explanation: Balance the reaction of KOH + H3PO4 = K3PO4 + H2O using this chemical equation balancer!
Hello there!
<span> Use Avogadro's number, 1 mol = 6.02 x 10^23 atoms.
</span>Convert atoms to moles and you get:
<span>9.97x10^(-15) moles Co
</span>
Hope This Helps You!
Good Luck :)
Answer:
a. 58.5 g/mol
b. 0.1 mol
Explanation:
a.
The molar mass of Na is 23.0 g/mol. The molar mass of Cl is 35.5 g/mol. The molar mass of NaCl is:
M(Na) + M(Cl) = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol
b. A healthy adult should eat no more than 6 g of salt in one day. The moles corresponding to 6 g of NaCl are:
6 g × (1 mol/58.5 g) = 0.1 mol
Answer:
The products of an endothermic reaction are less chemically stable.
Explanation:
They required an input of energy to create so naturally they are at a higher energy state.
