Answer:
Solvent
Explanation:
Many people use the solute to describe the solid being dissolved and the solvent to describe the thing doing the dissolving, but really solvent means the part of the solution with a greater amount/concentration.
For example, if you have 1 gram of salt in 10 liters of water, the water is the solvent.

Answer:
2.881x10^23 atoms
Explanation:
From the studies of Avogadro's hypothesis, we discovered that 1mole of any substance contains 6.02x10^23 atoms.
Therefore 1mole of Fe contains 6.02x10^23 atoms.
Molar Mass of Fe = 56g/mol
56g of Fe contains 6.02x10^23 atoms.
Therefore, 26.8g of Fe will contain = (26.8x6.02x10^23) / 56 = 2.881x10^23 atoms
For H2O(l) at 100 ∘C, d=0.958gcm−3 and ΔvapH=40.7kJmol−1.
Exothermic
Explanation:
A chemical reaction that has ΔH of -2764Kj indicates that the reaction that took place was an exothermic reaction.
- The enthalpy changes accompanying a reaction causes heat changes.
- In an exothermic reaction, heat is usually liberated to the surroundings.
- The environment becomes hotter at the end of the reaction.
- It is assigned a negative value because the sum of the heat contents of products is less than that of reactants.
- A positive sign is for an endothermic reaction.
