Information would you need to know about the H₂O₂ solution is through stoichiometry experiment
The ideal gas constant R can be found experimentally by determining the number of moles of gas that occupies a particular measured volume at a known pressure and temprature and the H₂O₂ is a chemical compound used un various chemical reactions and is slightly viscous than water and the experiment by decomposition of hydrogen peroxide and using the ideal gas law rearrangement equation we can calculate the value of r and we will need the information such as concentration, volume and moles of H₂O₂ to determine its stoichiometry

Answer: The balanced equation is 
.
Explanation:
The given reaction equation is as follows.
Number of atoms present on reactant side are as follows.
- Li = 1
- H = 1
= 1
Number of atoms present on product side are as follows.
- Li = 1
- H = 2
- = 1
To balance this equation, multiply Li by 2 and 
by 2 on reactant side. Also, multiply 
by 2 on product side.
Hence, the equation can be rewritten as follows.
Now, number of atoms present on reactant side are as follows.
- Li = 2
- H = 2
- = 2
Number of atoms present on product side are as follows.
- Li = 2
- H = 2
- = 2
As there are same number of atoms on both reactant and product side. Hence, the equation is now balanced.
Thus, we can conclude that the balanced equation is .
Answer:
north pole, south pole, and magnetic field
Explanation:
the earth basically has a giant bar magnet inside it( the axis). Earth has a north pole, a south pole, and a magnetic field which are the same things that a bar magnet has.
When the neutrons and electrons are the same. For example, sodium (Na) has an atomic mass of 11, meaning it has 11 protons and 11 electrons etc.
Answer:
Q = 1252.82kJ
Explanation:
Mass = 179g
Initial temperature (T1) = 25°C = (25+273.15)K = 298.15K
Final temperature (T2) = 82.70°C = (82.70 + 273.15)K = 335.85K
Specific heat capacity (c) = 121.3J/g.K
Heat energy (Q) = mc∇T
M = mass of the substance
Q = heat energy
c = specific heat capacity of the substance
∇T = change in temperature of the substance = T2 - T1
Q = mc∇T
Q = 179 × 121.3 × (355.85 - 298.15)
Q = 21712.7 × 57.7
Q = 1,252,822.79
Q = 1252.82kJ
The heat energy required to heat 179g of acetic acid from 25°C to 82.70°C is 1252.82kJ
