Answer:
4687.5 mL
Explanation:
Given that the density of the substance = 8.96 g/mL
Mass = 42.0 kg
The conversion of kg into g is shown below as:
1 kg = 1000 g
So, mass = 42.0 × 1000 g = 42000 g
Volume = ?
So, volume:
The volume of the 42.0 kg of the substance = 4687.5 mL
The reactant is dissolved in water
A gas and a liquid are produced
The H3O in a solution is 12.57.
<u>Explanation</u>:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.
pOH = -log[H3O]
pOH = -log(3.75x10^-2)
= 1.43
Now, pH = 14 - 1.43
= 12.57
The H3O in a solution is 12.57.
The nearest dollar would be 1 dollar because 3 is closer to 1 than to 5 or to 10 so therefor you would be rounding down.
Answer:
a. When one substance transfers electrons to another.
Explanation:
The redox reaction occurs when one substance oxides and other reduces. To oxide, the compound must lose electrons, and to reduce, it must gain electrons. So, when it's observed that electrons are being transferred, we can tell that a redox reaction is happening.
The oxygen is a good oxidation agent and intends to reduce, but the combustion reaction, for example, involves oxygen and it's not a redox reaction. The reaction between a metal and a nonmetal not necessarily will be a redox reaction.
