I will give brainliest. 1. A spiderweb and a Kevlar jacket have some obvious differences. Which property is similar between the

web and the jacket?
- surface area
- thickness, expressed as a number of atoms
- overall strength
- arrangement of atoms in molecules
2. Assuming silk from spiderwebs could be made just as strong as Kevlar, why would a company still choose to use Kevlar in producing bulletproof fabrics?
- A much larger amount of silk might be needed to produce the same effect.
- Spiderweb silk would likely be rejected by the body.
- The cost might be higher for producing spiderweb silk.
- Spiderweb silk likely involves more chemicals.
3. Which microscopic detail affects the strength of different forms of silk?
- Different silk strands are made with different types of atoms.
- Different types of silk are in long strands or in other very different arrangements.
- Different silk strands have different combinations of amino acids.
- Different types of silk do not have the same strength if they come from different sources.
4. Which type silk is the strongest?
- nonbiodegradable
- minor ampullate
- major ampullate
- biodegradable
5. Which natural source has been bioengineered to make silk proteins?
- mulberry leaves
- goat milk
- goat hair
- mulberry bark

How many moles of sulfur dioxide are in 2.26x10^33 sulfur dioxide molecules?
Alexus [3.1K]

Answer:moles = no. of molecules / Avogadro's number

          = 2.26 x 10^33 / 6.022 x 10^23

          = 3752906011

Round to significant figures which is 3 = 3.75 x 10^9 mol

Explanation:

The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro's number

a- If an Lithium (atomic number 3) atom has a -2 charge, how many electrons does it have? b- Why do you do it this way? c- Is th
Darina [25.2K]

Answer:

5

Explanation:

A lithium atom with an atomic number of 3 and a charge of -2 will have a total number of electrons.

The atomic number is the number of protons in an atom. For a neutral atom that has not gained or lost electrons, the atomic number is the same as the number of electrons.

   neutral atom: atomic number of electrons

For neutral atom of lithium, we will have 3 electrons

Now, lithium with a charge of -2 has gained two more electrons to the original 3 this now makes it 5.

ii.

It is an anion because it is negatively charged.

Negatively charged particles are called anion.
