Answer:
These particles were considered so small that they were unable to be cut
Answer:
A. H3O+/OH−
Explanation:
A conjugate acid-base pair are a pair of molecules that differ in 1 H⁺
A. The conjugate pair of H₃O⁺ = H₂O not OH⁻
B. The conjugate pair of NH₄⁺ is NH₃
C. The conjugate pair of C₂H₃O₂⁻ is HC₂H₃O₂
D. The conjugate pair of H₂SO₃ is HSO₃⁻
That means right option, that is not a conjugate acid-base pair, is:
<h3>A. H3O+/OH−
</h3>
We have that the total enthalpy of the reaction changes with the quantity of the reactants and it is proportional to them. Also, the reverse of a reaction has the opposite enthalpy. Hence, since we need to multiply by 2, the reactants are double and thus the value of the enthalpy is 2 as big. Also, since we are using the inverse reaction, we must also invert the sign. Thus, for this reaction we must use the value H=572 kJ.
Answer:The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound.
