Answer:
<em>Molecules of different gases with the same mass and temperature always have the same average kinetic energy - E.</em>
Answer:
<u>49 moles of atoms</u>
Explanation:
There are 7 individual atoms in each molecule of H2SO4: (2 hydrogens + 1 sulfur + 4 oxygens).
Therefore, if 7 moles are decomposed, there would be 7 times that amount of individual atoms:
7 x 7 = 49 moles of atoms
Answer:
V = 3.1 L
Explanation:
Given data:
Molarity of solution = 0.37 M
Mass of LiF = 29.53 g
Volume of solution = ?
Solution:
Number of moles of LiF:
Number of moles = mass/molar mass
Number of moles = 29.53 g/ 25.94g/mol
Number of moles = 1.14 mol
Volume:
Molarity = number of moles of solute / Volume in L
0.37 M = 1.14 mol / V
V = 1.14 mol / 0.37 M
V = 3.1 L (M = mol/L)
Answer:
<h2>The sequence is; b, e, a, d, c
</h2>
Explanation:
1. In a decomposition reaction; One reactant is broken down into two or more than two products is called decomposition.
2. A combustion reaction; A fuel is combined with oxygen to produce carbon dioxide and water, this reaction is called combustion reaction.
3. A synthesis reaction; it occurs when two or more reactants combine to form one product is known as synthesis reaction.
4. Double Replacement Reaction; Two compounds react to form two different compounds is known as double Replacement Reaction.
5. A single replacement reaction; occurs when a compound reacts with an element to form a new compound , this reaction is called as single replacement reaction.
