Answer:
Denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure, and secondary structure which is present in their native state, by application of some
Explanation:
PV = nRT
Where:
P = pressure in atm = 700/760 = 0.9211atm
V = volume = 8.29L
R = gas constant, 0.08206 atm-L/mol-K
T = temperature in Kelvin = 200 + 273 = 473
n = numbers of moles = Mass/molar mass
mass of the compound = 30.5
we can rewrite the equation above as
PV = (Mass)/(Molar mass) * RT
Atoms emit light when electrons in a higher energy orbital drop to a lower energy orbital. The energy of the emitted photon matches the energy lost by the electron and that energy determines the colour (blue is higher energy than red, UV even higher than blue and so on).
I believe the answer is A) light; chemical
Answer:
HgBr₂.
Explanation:
- To determine the empirical formula of the mercury bromide that is produced, we should calculate the no. of moles of Hg (1.750 g) and Br (1.394 g) used to prepare the mercury bromide.
no. of moles of Hg = mass/atomic mass = (1.75 g)/(200.59 g/mol) = 0.00872 mol.
no. of moles of Br = mass/atomic mass = (1.394 g)/(79.904 g/mol) = 0.01744 mol.
- We divide by the lowest no. of moles (0.00872) to get the mole ratio:
The mole ratio of (Br: Hg) is: (2: 1).
<em>So, the empirical formula is: HgBr₂.</em>
