What is the new fil what is the new volume win the piston is depressed increase the pressure by 25 50
Answer:
C ; Use enough cations and anions so that the total charge is zero
in a stable ionic compound, in order for you to get the formula, you need the positive and negative ions on one side to cancel out the compound, it becomes neutral, by being 0.
i hope that made sense :/
The answer to your question is D. Sound waves travel faster in more dense material, and the more dense the material the louder the sound is.
Answer:
Heat required to melt 26.0 g of ice at its melting point is 8.66 kJ.
Explanation:
Number of moles of water in 26 g of water: 26× 
moles
=1.44 moles
The enthalpy change for melting ice is called the entlaphy of fusion. Its value is 6.02 kj/mol.
we have relation as:
q = n × ΔH
where:
q = heat
n = moles
Δ
H = enthalpy
So calculating we get,
q= 1.44*6.02 kJ
q= 8.66 kJ
We require 8.66 kJ of energy to melt 26g of ice.
Answer:
1
Explanation:
Pyridine is a six membered hetrocyclic aromatic compound. Oxidation of the pyridine ring occurs at position-1.
Just like benzene, pyridine is stable towards mild oxidizing agents, however, pyridine is oxidized by peracetic acid to yield pyridine N-oxide.
