<h2>Let us solve for it </h2>

Explanation:

Magnesium oxide

  • It is MgO  
  • Its molecular mass is : 24 +16=40 g
  • When MgO decomposes it forms = 3.54 g of oxygen gas  
  • when 40 g of MgO decomposes it forms = 16g of oxygen  
  • or we can say that :
  • 16g of oxygen is produced when 40 g of MgO is decomposed .
  • 1g of oxygen will be formed from =40/16g of MgO  
  • 3.54 g of oxygen will be formed = 40/16 x 3.54 =8.85g of MgO

What environment will produce the largest crystal sizes?
VMariaS [17]
  • The pressure should be low as low pressure can melt the crystals easier way
  • According to Gay lussac's law pressure is directly proportional to temperature so temperature should be also low as it's general any thing need to be cooled down inorder to get crystallised
  • Now for amount of dissolved solids the solution should be super saturated like magma .It denotes that the particles present as solute must be greater than the solubility.
  • Cooling time also should be long inorder to give time to crystallization

What term best defines the process that occurs when nuclei combine to produce a nucleus with more mass?
bekas [8.4K]
I just answered your other question and wrote all the definitions of the terms. I would say this is probably refering to Fusion because you are fusing together more nuclei into one nucleus. Fusion= bringing separate things into one entity.
