Answer:Answer: (B) Archaebacteria
Explanation:
Explanation: Archaebacteria, like all prokaryotes, have no membrane bound organelles. This means that the archaebacteria are without nuclei, mitochondria, endoplasmic reticula, lysosomes, Golgi complexes, or chloroplasts. Because these organisms have no nucleus, the genetic material floats freely in the cytoplasm
Answer:
True
Explanation:
In a given molecule protons in the same chemical environment absorb at the same applied field strength; whereas protons with different chemical environments absorb at different applied field strengths.
A set of protons in the same chemical environment are said to be equivalent. Hence, the number of signals in the NMR spectrum tell us the number of sets of equivalent protons present in the molecule.
Splitting of a signal in a proton NMR spectrum tells us the number of chemically non-equivalent hydrogens in the immediate vicinity of the hydrogen giving the signal.
Answer:
received energy from water
Thank you for posting your question here at brainly. Below is the answer:
At 25 C and 1 atm pressure (the standard state): P is a solid, O2 is a gas, and Cl2 is a gas.
<span>P(s) + O2(g) + Cl2(g) ==> POCl3(l) </span>
<span>To make 1 mole of POCl3, we need to start with 1 mole of P, 1/2 mole of O2, and 3/2 mole of Cl2. </span>
<span>P(s) + 1/2O2(g) + 3/2Cl2(g) ==> POCl3(l) </span>
<span>NOTE: Some people write P as P4(s), in which case you would need 1/4 mole P4.</span>
