I can’t see the picture where’s it at
Answer: The pull of the moon's gravity on Earth's water causes tidal bulges to form on the side closest to the moon and farthest from the moon. In the place where there are tidal bulges, high tide occurs along coastline.
Explanation:
In a endothermic reaction energy from an outside source is continuously being added.
Water boils when the vapor pressure of the water equals the atmospheric pressure that's pressing down on it. Water boils at a lower temperature (more easily) at higher elevations (like on mountains), because:
- Atmospheric pressure is lower at higher elevation
- Easier for vapor pressure to equal this lower atmospheric pressure
Since the water boils at a lower temperature, it takes longer for the pasta to cook.
Answer and Explanation:
<em>Metallic bonding occurs between two or the same metals. In a metallic bonding structure, there is an electrostatic attraction between the positive metal ions leaving a sea of delocalised electrons. The sea of delocalised electrons allows metals to conduct electricity because the delocalised electrons are free to carry charge around the structure.</em>
<em>Pure metals are soft because there are layers of metal ions free to slide over each other as they are in a regular arrangement, pattern and size. </em>
<em>Alloys can be harder than pure metals because the different sizes of the atoms disturb the layers, stopping them from sliding over each other. Alloying a pure metal can let the metal become stronger and less reactive.</em>
