Answer:
A.
Explanation:
Radiation moves heat through electromagnetic waves which is equivalent to empty space.
The particles can move around each other because they do not have as strong bonds as solids do.
Answer:
Molar mass of monoprotic acid is 1145g/mol.
Explanation:
The reaction of a monoprotic acid (HX) with NaOH is:
HX + NaOH → H₂O + NaX
That means 1 mole of acid reacts with 1 mole of NaOH
If the neutralization of the acid spent 20.27mL of a 0.1578 M NaOH solution. Moles of NaOH are:
0.02027L × (0.1578mol / L) = <em>3.199x10⁻³ moles</em> NaOH ≡ moles HX.
As mass of the sample is 3.664g, molar mass of the acid is:
3.664g / 3.199x10⁻³ moles =<em> 1145g/mol</em>
Answer: it measures temperature
Explanation:
2.4368 MILOGRAMS is burned
