Answer:
75603.86473 K
Explanation:
Given that:
The 1st excited electronic energy level of He atom = 3.13 × 10⁻¹⁸ J
The objective of this question is to estimate the temperature at which the ratio of the population will be 5.0 between the first excited state to the ground state.
The formula for estimating the ratio of population in 1st excited state to the ground state can be computed as:
From the above equation:
Δ E = energy difference = 3.13 × 10⁻¹⁸ J
k = Boltzmann constant = 1.38 × 10⁻²³ J/K
Thus:
T = 75603.86473 K
Answer: Minor side effects of macrolides are nausea, vomiting, diarrhea, and ringing or buzzing in the ears. Serious side effects, are allergic reaction and cholestatic hepatitis
For Sulfas the side effects are nausea, vomiting, diarrhea, and loss of appetite may occur. Serious side effects are severe allergic reaction, skin rashes, kidney, liver, or blood disorders.
Sp2 hybridization forms 1 sigma bond and 1 pi bond.
Answer:
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. ... The nucleus of an atom contains protons and neutrons
Explanation:
Microwaves are defined as electromagnetic radiations with a frequency ranging between 300 MHz to 300 GHz while the wavelength ranges from 1 mm to around 30 cm. The microwave radiation is commonly referred to as microwaves. They fall between the infrared radiation and radio waves in the electromagnetic spectrum. radio waves in the electromagnetic spectrum.
