You can infer that the size of sugar particles that are dissolved in a mixture of sugar and water are very small since you cannot see the sugar particles. Sugar is an organic compound which is held by covalent bonding. When we dissolve sugar in water, it does not ionizes or dissociates rather it stays as a sugar molecule dissolved in the solvent which is water. These particles are very which is impossible to be seen by the naked eye. Dissolution involves the solute particles and solvent particles interacting and attracting each other forming a solution. Sugar molecules are attracted to water since it is a polar molecule.
Answer:
Na
Explanation:
because sodium has 1 electrons so it loses it to be stable and so have positive charge of 1
The answer is A. 2 electrons will go in 1s orbital, 2 more electrons will go in 2s orbital. because the last 5 electrons will go in the 2p orbital but you only want the s orbitals
Answer:
B) Heat is given off.
Explanation:
When heat is given off, a chemical change must have occurred and such a reaction is termed an exothermic reaction.
A chemical change is one in which;
- the process is not easily reversible
- leads to the production of new kinds of matter
- involves change in mass
- requires a considerable amount of energy.
Most chemical reactions are accompanied by heat changes.
