What is the mass of a sample of iron that has had 300.0 j applied to it and heats up from 20.0 degrees Celsius to 40.0 degrees C
yuradex [85]

Answer:

The mass of a sample of iron that has had 300 J applied to it and heats up from 20 degrees Celsius to 40 degrees Celsius is 32.61 grams.

Explanation:

Calorimetry is the measurement and calculation of the measurement of heat changes exchanged by a body or a system produced in physical and chemical processes.

The sensible heat of a body is the amount of heat received or transferred by a body to produce a change in temperature but without a change in physical state.

The sensible heat in a constant pressure is calculated by:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, constituted by a substance of specific heat c, and where ΔT is the temperature variation (ΔT=Tfinal - Tinitial)

In this case:

  • Q= 300 J
  • c= 0.46 \frac{J}{g*C}
  • m= ?
  • Tfinal= 40 C
  • Tinitial= 20 C

Replacing:

300 J= 0.46 \frac{J}{g*C} * m* (40 - 20) C

Solving:

300 J= 0.46 \frac{J}{g*C} * m* 20 C

m=\frac{300 J}{0.46 \frac{J}{g*C} * 20 C}

m= 32.61 g

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()bao
just olya [345]

Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.

Given chemical reaction is:

BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄

Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.

Hence the required coefficients is 1.

How do you tell if an element is a solid, liquid or gas (ex. Na2S)
svetoff [14.1K]
Solids have a definite shape, and a definite volume.
Liquids have a definite volume, but have no definite shape.
Gas have neither a definite volume nor a definite shape.

Hope this helps!
