I will solve this question assuming the reaction equation look like this:
<span>MnO2 + 4 HCl ---> MnCl2 + Cl2 + 2 H2O.
</span>
For every one molecule of MnO2 used, there will be one molecule of Cl2 formed. If the molecular mass of MnO2 is 87g/mol and molecular mass of Cl2 is <span> 73.0 g/mol, the mass of MnO2 needed would be:
Cl mass/Cl molecular mass * MnO2 molecular mass=
25g/ (73g/mol) * (87g/mol) * 1/1= 29.8 grams</span>
Use formula: Initial Pressure x Initial Volume/Initial temperature = Final pressure x Final Volume/Final Temperature => 17.15L
Answer:
The response can be defined as follows:

ATP is a hydrolysis energy-saving money of the cell. It is used to support the cell's endothermic processes.

Question∵
Compared to visible light, an electromagnetic wave that has a longer wavelength will also have?
Answer:
Hi, There! -Randp12- My Name Is jay I'm here to help! :)
<u><em>The correct answer is lower frequency.</em></u>
Explanation:
Information to Support My Answer :D
it is visible that wavelength and frequency follow inverse relation. For increase in wavelength, the value of frequency decreases and vice-versa.
Therefore for higher wavelength, the electromagnetic wave will also have lower frequency.
Hope this helps!

Answer:
Oxidation: A process in which an atom loses an electron and therefore increases its oxidation number. ... So oxidation reactions need not involve oxygen. This redox reaction is actually the sum of two separate half-reactions (a reduction half-reaction and an oxidation half-reaction).
