Answer:
We produce 2.0 moles of KCl when we have 2.00 moles K and and excess Cl2
Explanation:
Step 1: Data given
Number of moles K = 2.00 moles
Cl2 is in excess, so K is the limiting reactant
Step 2: The balanced equation
2K + Cl2 → 2KCl
Step 3: Calculate moles KCl
For 2 moles K we need 1 mol Cl2 to produce 2 moles KCl
We produce 2.0 moles of KCl when we have 2.00 moles K and and excess Cl2
Answer:
I don't know 100% but im pretty sure its electrons, if im wrong im really sorry let me know in the comments ill change it
explanation
the nucleus has more weight but its more compact but the electrons are spread apart circling the nucleus and therefor take up more space
The mass that the aerogel insulation added to the aircraft, with respect to glass, is 8.8 × 10³ g.
The density of the aerogel is 0.00011 lb/in³. We will convert it to g/cm³ using the following conversion factors:
If the maximum space for insulation in the spacecraft's hull was 2921 cm³, the mass that would occupy the aerogel with a density of 0.0030 g/cm³ is:
Glass is about 1000 times denser than aerogel. That is,
If the maximum space for insulation in the spacecraft's hull was 2921 cm³, the mass that would occupy the glass with a density of 3.0 g/cm³ is:
The mass that would add the aerogel with respect to the glass is:
The mass that the aerogel insulation added to the aircraft, with respect to glass, is 8.8 × 10³ g.

Gas.
Solid is the slowest; it stays together, so the molecules don't move much.
Liquid is the middle; it stays together for the most part, but it can move.
Gas is the fastest; they can move all over the place!
