Answer:
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly colored gas.
Answer:
The limiting reactant is propene, 
.
Explanation:
Moles of nitrogen propene = 2 mol
Moles of oxygen = 10 mol
According to reaction, 2 moles of propene reacts with 9 moles of oxygen gas, then 2 moles of propene will react with:
According to the question, we have 10 moles of oxygen gas, which is more than 9 moles of oxygen gas. This indicates that propene is present in a limiting amount hence, it is a limiting reactant.
The limiting reactant is propene, hence the correct answer is the .
Answer:
Those in lightning are charged and those in water are not charged.
Explanation:
The particles in lightning differs from those in a water in that water molecules are neutral and those of lightning are charged.
Lightning is made up of charged ions or particles that have either lost or gained electrons.
Lightning is produced as a burst or discharge of charged particles that are imbalanced withing the clouds.
Water molecules are made up of hydrogen and oxygen atoms which forms molecules held together by strong intermolecular and interatomic bonds.
Due to the sharing of electrons that has made this bonding possible, there is a net charge balance which leads to a neutrality.
Water is electrostatically neutral and not charged.
The pair that results in the most effective buffer is .50 M Ha and .50 M A-.
<span>A </span>buffer's<span> capacity
is the pH range where it works as an </span>effective buffer, preventing large changes in pH upon addition of
