D
Explanation:
total mass should be equal on both sides
it's a double do displacement reaction
HCl + NaOH --> NaCl + H2O
Answer:
The 3rd Law
Explanation:
The rockets burns fuel, pushing down onto the ground which then creates equal force pushing it up.
Answer is: <span> </span>ΔG for <span>methylamine is 18.85 kJ/mol.
</span>ΔG = R·T·lnK.
ΔG is Gibbs energy.
<span>T is the temperature on the Kelvin scale.
R is </span><span>ideal gas constant.
R = 8.314 J/mol</span>·K.
T = 25°C = 293.15 K.
Kb = 0.00044.
ΔG = - 8.314 J/mol·K · 293.15 K · ln(0.00044).
ΔG = 18836.85 J = 18.84 kJ.
Answer:
Molecular compounds consist of two or more nonmetals. The nonmetals that make up a molecular compound are held together by covalent/molecular bonds. Covalent bonds is known as the "sharing" of valence electrons between two or more chemical species. Valence electrons are shared so that the atoms of the compound can become stable, much like how ionic bonds transfer valence electrons between atoms to achieve stability.
<span>c. The molecules are closer together as a gas than they do as a liquid.</span>
