Aluminum and copper because all of them have advantages and disadvantages over iron alloys.
Answer: MgAl2O4 or Spinel (gemstone)
Explanation:
Answer:
D. > 7
Explanation:
Benzoic acid, HX, is a weak acid that reacts with OH- as follows:
HX + OH- → X- + H2O
<em>Where X- is produced, the conjugate base of benzoic acid.</em>
As benzoic acid is a weak acid, benzoate ion is a strong base. A strong base has pH > 7. Right option is:
D. > 7
DNA replication must create two sets of chromosomes.
Explanation:
Mitosis is where the cell divides itself into two identical parts.
In order for the two cells to be identical, they need to have the same parts, which is where replication is important
If the cell didn't replicate its organelles, it would not be able to split itself since nothing would go into one of the halves
Replication is the duplication of those organelles so that the sister cells are the same, so making a copy of the nucleus and other organelles allows one of those parts to stay and one part to go into the new cell
Answer:copper(II) sulfate, CuSO4> 2-pentanol, C5H11OH> methane, CH4>propane, C3H8.
Explanation:
Solubility depends on the ability of solute to interact effectively with a solvent. If water is the solvent, it interacts effectively with ionic substances. copper II sulphate is ionic and will be the most soluble in water, 2-pentanol, will interact effectively with water via hydrogen bonding. Between methane and propane, methane will interact better with water since it has a shorter alkyl chain than propane
