The solution can be evaporated such that only 10mL of the solution remains in that way, we can have a solution of pH 12.00.
What is pH?The pH refers to the degree of acidity or alkalinity of solution. We can obtain the concentration of each solution from the pH as follows;
At pH = 13;
[OH^-] = Antilog (-13) = 1 * 10^-13 M
At pH 12
[OH^-] = Antilog (-12) = 1 * 10^-12 M
Using the formula;
C1V1 =C2V2
1 * 10^-13 M * 100 mL = 1 * 10^-12 M * VmL
VmL = 1 * 10^-13 M * 100 mL/1 * 10^-12 M
VmL = 10mL
The solution can be evaporated such that only 10mL of the solution remains in that way, we can have a solution of pH 12.00.

A book has a mass of 400g the surface of the book in contact
Answer:
The pressure exerted on the table due to the book is 200 N/m².
Explanation:
The pressure exerted on the table due to the book is 200 N/m².
The given parameters;
mass of the book, m = 400 g = 0.4 kg
dimension of the table, = 0.10m x 0.20 m.
gravitational field strength g = 10 N/kg.
The area of the table is calculated as follows;
A = 0.1 x 0.2 = 0.02 m²
The pressure exerted on the table due to the book is calculated as follows; where;
F is the force of the book due to its weight
Thus, the pressure exerted on the table due to the book is 200 N/m².

Explanation:
if those fossil fules get in the air it bad gib brainiest
"Reusing, reducing, or recycling" could decrease the amount of fossil fuels used as it lowers global warming/litter.
Why are 3R's used?Reduce is referred to the lowering use of the substance, resources, or any other items. Reuse refers to the repeated benefit or a resource, item, or any substance.Recycling is the process of collecting and processing the materials again to avoid it throwing them in the trash.
The 3R's are the reduce, reuse, and recycle the waste or products. Reduce is referred to diminish the use of certain products or resources, reuse is to repeated use of items, and recycle is to mold and develop into a new item.
Throwing antifreeze can become ilegal because it gets heavy metals such as lead, cadmium and chromium that make it hazardous waste, which should not be thrown in public areas.

The volume of the assumed shape is 235.5 cm³
How to calculate the volume of a geometric shape?The question is incomplete as the dimensions or the figure is not given
So, I will provide a general solution
Assume the shape is a cylinder, with the following parameters:
Radius, r = 5 cm
Height, h = 3 cm
The volume is:
V = π r² h
This gives
V = (3.14) (5 cm)² (3 cm)
Evaluate the product
V = 235.5 cm³

Multiplication as a method of elimination is used to eliminate an unknown in a system of equations by multiplying one of the equations by a constant.
What is the Gauss method?It is the method of eliminating unknowns that transforms a linear system into a triangular system, so that it is possible to solve the problem with retroactive resolution. Like for example:
2x+3y=143x-4y=4A) The first step is to solve equation 2 to find the variable x.
3x=4y+4x=4y/3+4/3B) The second step is to include the variable x found in equation 1.
2x(4y/3+4/3)+3y=14
17y/3=34/3
17y=34
C) The third step is to solve equation 1 to find the variable y.
17y=34y=2D)Now that we've found the value of y, we can solve equation 1 to find the value of x.
x=4/3x(2)+4/3=4Therefore, if the value of x is 4 and the value of y is 2, the solution of this exercise, using the Gauss method is (4;2).
