Question 4 (higher question)

Chemistry
1 answer:
Jet001 [13]3 years ago
8 0

Answer:

Explanation:

Describe means you should recall facts, events or processes accurately. You might need to give an account of what something looked like, or what happened.

Explain means you need to make something clear, or state the reasons for something happening.  

Compare means you need to describe similarities and differences between things. If you are asked to compare X and Y, write down something about X and something about Y, and give a comparison. Do not just write about X only or Y only.

Evaluate means you must use information supplied, or your own knowledge, to consider the evidence for and against or to identify strengths and weaknesses. You must then complete your answer with a conclusion, stating which is better and why, for example.

Why Basalt and gabbro are denser than granite and<br> obsidian?
Maksim231197 [3]

Answer:

What do you think causes some rock types to have higher densities than others? (Assuming there are no air pockets in the rock, the types of minerals will determine the density. Granite contains lots of quartz and feldspar - both fairly light minerals, whereas basalt and gabbro are made of heavier minerals.)

A lab director asks two students, Lydia and Damien, to each select a bottle of a concentrated weak base. When they reach the cab
algol13

Lydia and Damien should select the bottle of weak base with high molarity(M)

<h3>Further explanation</h3>

According to Arrhenius, Base is a compound which in water releases OH- ions

Electrolytes (acids or bases) with a small degree of ionization are classified as weak electrolytes

If two students, Lydia and Damien, select each bottle of a concentrated weak base, then a guide can be chosen to choose some of the solutions available in the lab :

  • Base compounds are usually known from their names ending in hydroxide suffixes such as NaOH, sodium hydroxide
  • The weak base will be partially ionized in water because the ionization degree is close to 0 or less than 1
  • If there is a Kb value (base ionization constant), then this shows the strength of the base. The greater the value of Kb, the greater the base strength
  • If there are some weak bases, then Lydia and Damien choose the highest concentration, usually indicated by the value of Molarity (M)

Because no choice solution is included, the weak base example is:

Ammonia (NH₃)

Aluminum hydroxide (Al (OH)₃)

Copper (II) hydroxide Cu (OH)₂

Mercury (II) hydroxide Hg (OH)₂
