Answer:
a
Explanation:
it is an electrolyte because of its strong polar chemical bond
Answer:
The molecules absorb heat and acquire more kinetic energy.
Explanation:
In a solid, the solids only vibrate about their mean positions but do not translate. When energy is supplied to the molecule in the form of heat, the molecules vibrate faster. Eventually, they acquire sufficient energy to leave their mean positions and translate. Hence the solid crystal collapses.
When ice is heated, water molecules acquire sufficient kinetic energy to translate. The intermolecular bonds are gradually broken in the solid framework as heat is absorbed. The heat required for this is known as the latent heat of fusion.
The temperature remains constant until phase transition is over, then temperature rise resumes.
Answer:
"a chemical reaction in which acid and a base react quantitatively with each other"
Explanation:
The balanced reaction would be as follows:
<span>3NaOH + H3PO4 --> Na3PO4 + 3H20
We are given the concentration and the amount of the reactants to be used. We use these values for the calculations as follows:
</span><span>How many mL of .225 M NaOH will react with 4.568g H3PO4?
4.568 g (1 mol / 98 g) ( 3 mol NaOH / 1 mol H3PO4 ) ( 1 L / .225 mol NaOH ) = 0.621 L or 621 mL of .225 NaOH</span>
Answer:
The unbalanced chemical equation of propane combustion is
C₃H₈ (g) + O₂ (g) → CO₂(g) + H₂O(g)
Explanation:
Combustion is a type of chemical reaction in which there is the release of energy in the form of heat. This means that this reaction can be called exothermic.
When propane reacts with oxygen present in the air, it releases a high amount of heat. If the reaction is fully completed, the products are carbon dioxide and water vapor.
