Write the equation for the reaction and balance it. In this case the equation is: 2NaOH + H2SO4 → Na2SO4 + 2H2O
Convert the given amount to moles. Molarity, “M” is moles per liter. The given amount is 25 ml of 1.2 M H2SO4. Since Molarity uses Liters, the volume must be converted from ml to L.
Use the mole ratio in this case 2 moles of NaOH to ! mole of H2SO4
Convert the moles to the required units. In this case the required units are grams. The formula weight in grams er mole.
25 ml H2SO4 * 1L/1000 ml * 1.2 Moles/L * 2 moles NaOH/1 mole H2SO4 * 40 g NaOH/ 1 Mole NaOH
Perform these calculations and you have the answer! Timothy, When doing homework, the answer is NOT the important thing, the METHOD is! These 4 steps, combined with required changes in units will sove ANY stoichiometric problem easily.
Answer:
Water
Explanation:
one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Water is a tasteless, odorless liquid at ambient temperature and pressure. Which is known to be crystal blue.
Answer:
-100 K
Explanation:
<em>Kinetic energy is related to temperature.</em> The molecules in water will move faster in warmer temperatures than in colder ones.
100 K is equal to -279.67°F (-173.15°C). So 100 K would have the lowest average kinetic energy.
D) Chlorine, Cl. Hope that helped
Answer is: CaCl₂(s), calcium chloride.
Calcium cations and chlorine anions have a crystal structure in this solid inorganic salt. Ions have <span>the ordered arrangement.</span><span>
Ethane (C</span>₂H₆) is gas, g is chemistry
abbreviations or physical state symbol for gas, gases do not have a crystal structure.
Methanol (CH₃OH) is liquid, l is chemistry abbreviations or physical state symbol for liquids, it do not have a crystal structure.
Calcium iodide is dissolved in water, aqueous solution
(aq) do not have a crystal structure.
