Write a letter to your friend describing your feelings after you left the school
fredd [130]
Dear friend,
How are you doing? I finally switched to my new school and it's been so hard adjusting. But I know I have a new chance at making new friends and memories. Also, I can learn new things, like interacting with new people and how to keep my anxiety low. I really miss us hanging out and how much we'd laugh and get in trouble at class. But i really hope to see you soon & that it hasn't gone terribly wrong for you since i left.
your friend,
name

How many grams of calcium carbonate were used if you drew the periodic table on the sidewalk using
german

Based on the data provided, there are 25 g of calcium carbonate in 1.505 × 10^23 atoms.

<h3>What is the moles of calcium carbonate in 1.505 × 10^23 atoms of calcium carbonate?</h3>

The mole of a substance can be calculated as follows:

  • Moles of substance = number of particles/6.02 × 10^23

Moles of calcium carbonate = 1.505 × 10^23/6.02 × 10^23

Moles of calcium carbonate = 0.25 moles

The mass of calcium carbonate in 0.25 moles is calculated as follows:

  • mass = moles × molar mass

molar mass of a calcium carbonate = 100 g/mol

mass of calcium carbonate = 0.25 × 100 = 25 g.

Therefore, there are 25 g of calcium carbonate in 1.505 × 10^23 atoms.
