I think the correct answer from the choices listed above is option C. The mass of an ice cube is the total amount of water in the ice cube. Ice is the solid form of water. Hope this answers the question. Have a nice day. Feel free to ask more questions.

The right option is; c. total amount of water in the ice cube

Mass is an attribute of a physical body and a measure of the amount of matter present in an object. Mass is mainly measured in grams or kilograms.

The mass of an ice cube is the total amount of water in the ice cube. Ice is the solid form of water. For example, two pounds of ice cube will make two pounds of water after melting because its mass does not change. When in the ice form, the water molecules will spread apart and occupy more space or volume.

In the reaction, 3Cu + 2Al3+ → 3Cu2+ + 2Al, which substance is being oxidized?

Wittaler [7]

In this reaction, Copper is the element being oxidized because it is losing electrons. It starts with a neutral charge (0) and ends up with a 6+ charge. Because its charge is increasing, it is being oxidized (losing electrons).

When the volume of a gas is

Montano1993 [528]

Answer:

$\boxed {\boxed {\sf 232.9 \textdegree C}}$

Explanation:

This question asks us to find the temperature change given a volume change. We will use Charles's Law, which states the volume of a gas is directly proportional to the temperature. The formula is:

$\frac {V_1}{T_1}= \frac{V_2}{T_2}$

The volume of the gas starts at 250 milliliters and the temperature is 137 °C.

$\frac{250 \ mL}{137 \textdegree C}= \frac{V_2}{T_2}$

The volume of the gas is increased to 425 milliliters, but the temperature is unknown.

$\frac{250 \ mL}{137 \textdegree C}= \frac{425 \ mL}{T_2}$

We are solving for the new temperature, so we must isolate the variable T₂. First, cross multiply. Multiply the first numerator and second denominator, then multiply the first denominator and second numerator.

$250 \ mL * T_2 = 137 \textdegree C * 425 \ mL$
