An ultralight has and engine so it's heavier.
Sand is much heavier than grit. Sand should be used if you're trying to weigh something down.
Glass beads are heavier than plastic
No. You're an idiot
Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.
Beryllium density: 1,848 g/cm3 Bismuth density: 9,78 g/cm3
Lithium (Li) and Beryllium (Be) both have 2 electrons on their outer shell.
no
Group 2 carbonates, such as calcium carbonate, are thermally stable and decompose at high temperatures to form metal oxide and carbon dioxide. This decomposition reaction is an endothermic process that requires energy to break the carbonate bonds. The trend is observed that as you move down the group from lighter to heavier metals, the thermal stability of the carbonates increases.
All the alkali metals; the three heavier alkaline earth elements, calcium, strontium, and barium; and the white allotrope of phosphorus are all considered soft solids at room temperature.
Wood becomes heavier after getting burnt because the water content is reduced during the burning process, leaving behind mainly the carbon content in the form of ash, which is denser.
Magnesium oxide is heavier than magnesium because it contains an additional oxygen atom per molecule. This extra oxygen atom contributes to the overall molecular weight of magnesium oxide, making it heavier than pure magnesium.
Helium and metals (which basically means any element heavier than helium) are formed in the star's core.
A magnesium atom is about 24 times heavier than an oxygen atom. Magnesium has an atomic mass of approximately 24 atomic mass units (amu) while oxygen has an atomic mass of about 16 amu.
Yes, because it reacts with the oxygen in the air to form a new compound.
A carbon atom is about 12 times heavier than a hydrogen atom, while a calcium atom is about 40 times heavier than a hydrogen atom. Therefore, carbon atoms are 12 times heavier than hydrogen atoms, and calcium atoms are 40 times heavier than hydrogen atoms.
Helium is formed inside stars.The stars turn hydrogen into helium. Larger, older stars can create heavier elements. The formation is normally proton capture. But if helium fuses into beryllium-8, it is unstable. Only the "triple-alpha" process will add a third nucleus to form stable carbon-12, or a fourth to form oxygen-16. The formation of heavier elements from carbon (oxygen, neon, and magnesium) requires tremendous heat and pressure.
