Answer:

physical change is what the answer above is saying for anybody who is confused

Explanation:

a physical change has to do with appearance while chemical change has to do with composition. melting the sugar does not change the fact its just sugar therefore not changing the composition.

Answer:

Hola Amigo! Here's Ur Answer :D

Explanation:

The chemical reaction we are most familiar with is that of melting: sugar decomposes at a temperature ranging between 184 and 186°C. This is a very recent discovery we owe to a team of researchers in Illinois. Basically, when we heat sucrose gently, this produces a phenomenon known as “ apparent melting ”.

Happy to Help! :D

What is the volume of an object that has a mass of 3.5 grams and has a density of 2.50 g/mL? Include units and proper sig figs l

jolli1 [7]

1.4mL

Explanation:

Given parameters:

Mass of object = 3.5g

density = 2.5g/mL

Unknown:

Volume of the object = ?

Solution:

Density is the mass per unit volume of a body. It is an intensive property that is the same for the same substances.

Density = $\frac{mass}{volume}$

since the volume is unknown; we make it the subject of the formula;

Volume = $\frac{mass}{density}$

Volume = $\frac{3.5}{2.5}$

Volume of the object = 1.4mL

Al añadir 1g de urea a 100 ml de agua a 20ºC, la presión de vapor pasa de 17,54 mmHg a 17,49 mmHg. Determina la masa molecular d

never [62]

Answer: Los estudios teóricos y experimentales han permitido establecer, que los líquidos poseen propiedades físicas características. Entre ellas cabe mencionar: la densidad, la propiedad de ebullir, congelar y evaporar, la viscosidad y la capacidad de conducir la corriente eléctrica, etc. Cada líquido presenta valores característicos (es decir, constantes) para cada una de estas propiedades. Cuando un soluto y un solvente dan origen a una solución, la presencia del soluto determina una modificación de estas propiedades con relación a su estado normal en forma aislada, es decir, líquido puro. Estas modificaciones se conocen como PROPIEDADES DE UNA SOLUCIÓN.
