Answer:
<h3>The answer is 112.36 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 53 mL
density = 2.12 g/mL
We have
mass = 2.12 × 53
We have the final answer as
<h3>112.36 g</h3>
Hope this helps you

Answer:
Kindly check the explanation section.
Explanation:
When the Arsenic acid,H3AsO4 is put in water it dissociates to form or give out 1 proton, 2 protons or 3 protons that is 1H^+, 2H^+ and 3H^+. Check the equation showing the dissociation reactions as given below;
H3AsO4 ===========> H^+ + AsO4^-
H3AsO4 ===========> 2H^+ + AsO4^2-
H3AsO4 ===========> 3H^+ + AsO4^3-
Therefore, the total charge balance is given as:
[H^+] =[OH^-] + [ AsO4^-] + 2[ AsO4^2-] + 3[ AsO4^3-].
Kindly note that the [OH^-] is from water.
Method One of Three:
Identifying the Proper Waste Disposal Method
Read the material safety data sheet.
chemical products come with disposal instructions right on the label and following those instructions should be enough. Even for products without disposal instructions, you should still read the labels so you can be aware of the warnings and cautions concerning said products.
Items such as batteries and light bulbs have to be recycled at special recycling centers.
Never mix cleaning products together. If you only have a small amount of cleaning product left in each bottle, it may be tempting to mix them into one bottle for disposal. Different chemicals can react with each other to form very hazardous fumes and noxious gases.
Search the list of hazardous waste
In addition to the product label, you want to read the MSDS for industrial chemicals. The MSDS gives you important information about the chemical: its toxicity, reactivity, and disposal considerations.
Every chemical product you buy should come with an MSDS sheet. However, you can also use the online MSDS database to look up the MSDS for the specific formulation of the chemical you wish to dispose.[1]

Answer:
b. All rocks are made of minerals.
Explanation:
A rock is a mixture of two or more minerals. It does not usually have a specific shape. Granite consists of several different minerals.
A mineral has a specific composition in which the atoms occupy positions in a crystal lattice. Minerals like halite usually have a characteristic crystal shape.
Thus, all rocks are made of minerals, but minerals are not made of rocks.
