Answer:
diamonds are carbon based and have a giant covalent structure
Explanation:
This is what gives diamonds its strength and rigidity.
Diamonds are different from graphite due to the way the atoms are arranged
Answer:
0.085 kg
Explanation:
1 g=0.001 kg OR 1 kg=1000 g
so 
=0.085 kg
The concentration of hydrogen ions in a solution is a measure of its acidity. So the correct option is (b) false.
When an Arrhenius acid is dissolved in water, hydrogen ions are produced:
H+(aq) + A- = HA + H2O (aq)
Here, H+ is the hydrogen cation, A- is the solvated anion, also known as the conjugate base, and HA is the non-dissociated acid. When an Arrhenius base is dissolved in water, hydroxide ions are produced:
BOH + H2O → B+(aq) + OH-(aq)
Is a material with at least one hydrogen atom that has the ability to split apart in an aqueous solution to produce an anion and an H + ion (a proton), creating an acidic solution. Bases are substances that, when dissolved in water, create hydroxide ions (OH) and a cation, resulting in a basic solution.

Answer:
Growing population
The worlds developing regions will see 1.2 billion people added, a 20.7% increase; while the population of developed countries will increase a mere 3.3% adding 41 million to the current 1.3 billion people.
Acetylsalicylic acid (ASA) or commonly known as aspirin is used as pain reliever, treatment for fever and inflammation. The type of bond that aspirin have is covalent bond. Covalent bond is when atoms share their electrons. Aspirin is made up of carbon, hydrogen and oxygen with a formula of C9H8O4.
