Draw a physical model that shows the reaction of zinc metal and hydrochloric acid (hydrogen chloride).
Zinc + Hydrochloric Acid Zinc Chloride and Hydrogen Gas
Zn + 2HCI - ZnCl2 + H2
“Be sure to label your model to clearly show how you are representing the atoms, how they are rearranged and
that mass is conserved in the reaction.”
If anyone could maybe send me a drawing it’ll be so appreciated! God bless you all :)

A car accelerates from 20 m/s to 40 m/s in 4 seconds. What is the car’s acceleration?
Answer:
40 - 20 = 20
20/4 = 5m/s
The difference in velocity divided by the rate = acceleration.

Step 2: Identify Conversions
Avogadro's Number
[PT] Molar Mass of Ca - 40.08 g/mol
[PT] Molar Mass of C - 12.01 g/mol
[PT] Molar Mass of O - 16.00 g/mol
Molar Mass of CaCO₃ - 40.08 + 12.01 + 3(16.00) = 100.09 g/mol

a. Identify the type of reaction shown:
Li + CaCl2 ---> LiCl + Ca
Answer:
single-replacement reactions
Explanation:
A single-replacement reaction is defined as a chemical reaction in which one strong element replace the other weak element.
The given chemical equation Li + CaCl2 ---> LiCl + Ca is an example of single-replacement reactions in which Lithium (Li) is stronger than Calcium (Ca) and replaces calcium to form bond with Chloride.
Hence, the correct answer is "single-replacement reactions".
If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many gits are equal to 5gews?
Answer:
500 hits
Explanation:
If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?
Solution:
Given that:
20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz
10 webs = 1 futz; hence:
1 web = 1 web * 1 futz / 10 webs = 0.1 futz
1 web = 0.1 futz
1 futz = 2 geese; hence:
0.1 futz = 0.1 futz * 2 geese / 1 futz
0.1 futz = 0.2 geese
Therefore, 1 web = 0.1 futz = 0.2 geese
1 web = 0.2 geese
This means that 20 hits = 1 web = 0.2 geese
20 hits = 0.2 geese
5 geese = 5 geese * 20 hits / 0.2 geese
5 geese = 500 hits

Limonene is an oil from oranges and lemons. Click on all the carbon
atoms its structures that have a trigonal planar molecular geometry.
Answer:
See explanation
Explanation:
Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.
There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.
Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

Convert 0.6330 mol of Na3PO4 to grams. Show the unit analysis by inserting the correct components into their unit- factor slots.
(see picture)
Answer:
No of moles = mass in gram / molar mass
Mass in gram = no of moles× molar mass
Mass in gram = 0.6330× 163.94
103.77 gram
