Answer:Metallic bonding As you can see, an electron is freely moving from one atom to another. As one metal atom loses an electron and becomes a positively charge ion, it immediately accepts one from another to become a neutral atom. This back and forth losing and gaining of electrons among atoms of the metal allow metals to easily conduct electricity.

Answer: 10^-11
Explanation:
to find the concentration of H+ ions given the ph, we use the formula 10^(-pH).
so 10^-11
Answer: 2.744 x 1025 molecules
Answer:
The law of conservation of mass states that mass is neither created nor destroyed but the mass of the system must remain constant over time. The total number of atoms in the reactants is equal to the total number of atoms in the product. Therefore, this chemical equation shows that energy is conserved and demonstrates the law of conservation of mass.
Well insulated houses use less energy to keep them warm. This means that less carbon dioxide, a greenhouse gas, is released into the atmosphere from burning of fossil fuels (coal, oil and gas) in our power stations and central heating boilers. Global warming is occurring because large volumes of greenhouse gases – including carbon dioxide – are accumulating in the Earth’s atmosphere. This causes the planet’s average air and ocean temperatures to increase and sea levels to rise, resulting in increasingly severe weather conditions. This effect is called climate change and it’s already happening. By improving the insulation of your home, you will be playing your part in reducing the effect of global warming.
