Answer:
- have high melting and boiling points
- are hard
- are good conductors of electricity when dissolved in water
Explanation:
Ionic compounds are compounds that are formed between a metal and non-metal with a significant electronegativity difference. The metals transfers their electrons to the non-metals and the electrostatic attraction of the ions brings about the bonding that forms the compound.
Ionic compounds are diverse in nature and form.
Here are some of their properties:
- They are usually hard solids with a high melting point or liquids with high boiling points
- They are soluble in water and non-soluble in non-polar solvents
- They are able to conduct electricity in molten form.
- They undergo very fast reaction in aqueous solutions.
Answer:
I believe it’s the mitochondria
Explanation:
Answer:
In chemistry, catenation is the bonding of atoms of the same element into a series, called a chain. A chain or a ring shape may be open if its ends are not bonded to each other, or closed if they are bonded in a ring
Explanation:
Answer: arrangement of constituent particles makes glass diff. from quartz. Glass-short range order of particles.
Quartz-Long range of particles.
If quartz is heated and cooled rapidly it can be converted to glass.
Mg3(PO4)2 - the molar mass would be 262g/mol, which is 100%
Atomic mass of Mg is 24, since we have 3Mg we multiply by 3 and get a mass of 72
262 : 100% = 72 : x%
x = 72*100 / 262
x = 27.5%
And do that for every element — get the molar mass of P and multiply by 2, use a ratio, and get the molar mass of O and multiply by 8 and use ratios :)
