Answer:
An elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electron.
Example:
The nucleus of a hydrogen atom or the H+ ion is an example of a proton. Regardless of the isotope, each atom of hydrogen has 1 proton; each helium atom contains 2 protons; each lithium atom contains 3 protons and so on.
Answer:
Chlorine, the gas, and ethanol, the alcohol do not react together in that form
Explanation:
Answer:
The percent of mass of GaBr₃ in the solid mixture is 30.2 %.
Explanation:
GaBr₃(aq) + 3 AgNO₃(aq) ⟶ 3 AgBr(s) + Ga(NO₃)₃(aq)
MW GaBr₃ = 309.4 g/mol
MW AgBr = 187.8 g/mol
187.8 g AgBr _______ 1 mol
0.368 g AgBr _______ x
x = 2.0 x 10⁻³ mol AgBr
1 mol GaBr₃ ____ 3 mol AgBr
y ____ 2.0 x 10⁻³ mol AgBr
y = 6.7 x 10⁻⁴ mol GaBr₃
1 mol GaBr₃ ____________ 309.4 g
6.7 x 10⁻⁴ mol GaBr₃ ______ w
w = 0.206 g GaBr₃
0.6813 g _____ 100%
0.206 g _____ z
z = 30.2 %

Please see the answer..hope its works
Explanation:
The NMR spectrometer will acquire data for the wrong chemical shift range and you will potentially have skewed data when opening spinworks-NMR spectrometer examines a specific 12 ppm range based on the expected solvent peak, and if a different solvent is used a different range may be examined
To explain further, If the user declares the wrong solvent, one of two things may happen. Firstly, the spectrometer may not be able to establish a deuterium lock and will report an error and not run the sample. Secondly, the spectrometer may be able to establish a lock despite the fact that the deuterium signal is off resonance. If the lock is established, the field strength will be set to a value appropriate to put the declared solvent signal on-resonance. When a proton NMR spectrum is collected, the chemical shift scale will be incorrect by an amount equal to the proton chemical shift difference between the true solvent and the declared solvent.
Answer:
According to Boyle's Law, an inverse relationship exists between pressure and volume. Boyle's Law holds true only if the number of molecules (n) and the temperature (T) are both constant.
