Q = 1.161 J/kg of heat is required to melt 99.9 g of solid acetic acid (HCH,CO2). Q = mL(Latent heat is the energy emitted or absorbed by a body while changing it state ). (Latent heat is the energy released or absorbed by a body while changing it state ).

<h3>How to fix?</h3>

Apply the equation Q = mL where:

Energy is Q. (J)

m = Mass (g)

L = Acetic acid's latent heat of fusion 192(J/g) = J/g

Q is equal to 0.099 kg times 11.73 kj/mol.

Q = 1.161J/kg.

<h3>What is latent heat, and what varieties are there?</h3>

Latent heat is the amount of energy that a substance experiencing a change in state, such as ice turning into water or water turning into steam, can absorb or release while maintaining a constant temperature and pressure. Types: The material exists in three states: solid, liquid, and gaseous.

<h3>What does "sensible heat" mean?</h3>

Heat that can actually be felt is considered to be sensible heat. Instead of the phase shifting, energy is what causes the temperature to vary as it moves from one system to another. For instance, it warms the water instead of melting the ice.

If a projectile flies 387 meters north in 8.5 seconds, what is its velocity?
Eddi Din [679]
Ok so velocity is speed but includes direction. The formula for both speed velocity is distance over time. so the equation is 387 over 8.5. That equals 45.5294117647 which can be rounded to 46.

How much eneregy is released when 10.0 g of methanol is burned?
MAVERICK [17]
Well the first thing you need to know is how much energy that 1g methanol release which is fixed value

Methanol CHOH is 17000 j/g
so the energy released when 10.0g of methanol is burned
=10x 17000
=170000 j

Metallic bonds are responsible for many properties of metals such as conductivity true or false?.
Alex17521 [72]

It is true that metallic bonds are responsible for many properties of metals such as conductivity.

Metallic bond is a type of chemical bond.

Metallic bond is formed between electrons and positively charged metal ions.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.

Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

Metallic bond increace electrical and thermal conductivity.
