Here is how i made slime when i had a buisiness.

Add glue to a bowl.

13 pumps of foaming hand soap

a table spoon of cornstarch

coloring

borax

add everything but borax and stir! then slowly add borax and knead until it is at your desired texture :D

**Answer:**

15 people x 4 slices so you’ll need 60 pieces

60/12(the amount of slices per pizza) =5

You need 5 pizzas. $14.78 x 5 = 73.90.

**Explanation:**

the answer is that one 73.90 is rounded nearest cent : ) took me a while to get it

**Answer:**

Nonmetals

**Explanation:**

Nonmetals typically lacks the metallic bonding which allows substances to exhibit metallic properties that confers special properties on them.

- Metals are malleable and ductile
- They are also able to conduct electricity due to the sea of electrons present within their structure.
- Metals can be made into wire and drawn into sheets.

Nonmetals lacks these properties but metalloids are able to show some of the properties under certain and special conditions.

**Answer:**

The answer to your question is P2 = 2676.6 kPa

**Explanation:**

**Data**

Volume 1 = V1 = 12.8 L Volume 2 = V2 = 855 ml

Temperature 1 = T1 = -108°C Temperature 2 = 22°C

Pressure 1 = P1 = 100 kPa Pressure 2 = P2 = ?

**Process**

**- To solve this problem use the Combined gas law.**

P1V1/T1 = P2V2/T2

**-Solve for P2**

P2 = P1V1T2 / T1V2

**- Convert temperature to °K**

T1 = -108 + 273 = 165°K

T2 = 22 + 273 = 295°K

**- Convert volume 2 to liters**

1000 ml -------------------- 1 l

855 ml -------------------- x

x = (855 x 1) / 1000

x = 0.855 l

**-Substitution**

P2 = (12.8 x 100 x 295) / (165 x 0.855)

**-Simplification**

P2 = 377600 / 141.075

**-Result**

P2 = 2676.6 kPa
