False
The stirring allows fresh solvent molecules to continually be in contact with the solute. If it is not stirred, then the water right at the surface of the solute becomes saturated with dissolved sugar molecules, meaning that it is more difficult for additional solute to dissolve.
Answer:
Image result for Which hydrogen is an unsaturated hydrocarbon ?
Alkenes have the general formula CnH2n, and are examples of unsaturated hydrocarbons. The presence of a double bond compound's structure causes there to be two fewer hydrogen atoms in the molecule than there are in an alkane with the same number of carbon atoms.

Your answer: Yes! Light is the fastest thing in the world!. Its even proved in the modern physics. Even if the light going through an empty space, its velocity will be constant and steady.

Answer:
O Bromine
Explanation:
The element that will attract electrons in a chemical bond is Bromine.
An element that attracts electrons in chemical bonds is said to be an electronegative element.
Such an element have a relative tendency to attract valence electrons in a chemical bond.
- The most electronegative group on the periodic table is that of the halogens.
- Halogens are a special class of electronegative elements.
- They need just one electron to complete their octet, hence the reason for their electronegativity.
- Metals are electropositive and are not ready to attract electrons. They prefer reactions where they can lose electrons.
