Answer:
A
Explanation: this is because 1. the particles were HELD together. after the particles are released, they move with their own forces in opposite direction as such, they move in their respective directions.
2. when we consider the electrostatic force of attraction, oppositely charged particles would attract when the depletion boundaries are exceeded as such they tend to move in the direction of the force with the greatest magnitude
As the
Sodium Ion contains +ve charge so it will interact with the
Oxygen atoms of water molecules. As Oxygen contains partial negative charge it will form intermolecular interaction with sodium Metal. The hydrogen atoms of water will point away from Sodium Ion due to repulsion. The best representation of interaction between Sodium ion (Na⁺) and water molecules is shown below,
Answer:
2HCr2O7(aq) + Ca(OH)2(aq) --> 2H2O(l) + Ca(Cr2O7)2
Explanation:
A neutralization reaction produces water and a salt. Since Ca(OH)2 has two hydroxides, two water molecules are produced, which means you also need two molecules of the acid. Having two molecules of the acid also ensures that you have two dichromates on both sides.
Answer:
Increasing the temperature of a system will increase the rate of a reaction. More particles are moving faster, and have more energy, increasing the overall rate of reaction.
