Consider the following intermediate chemical equations.
3 equations. 1: upper C solid plus upper o subscript 2 gas right arrow upper C upper O subscript 2 gas Delta H 1 equals negative 393.5 kilojoules. 2: 2 upper C upper O gas plus upper O subscript 2 gas right arrow 2 upper C upper O subscript 2 gas Delta H 2 equals negative 566.0 kilojoules. 3: 2 upper H subscript 2 upper o gas right arrow 2 upper H subscript 2 gas plus upper O subscript 2 gas delta H 3 equals 483.6 kilojoules.
The overall chemical equation is Upper C (s) plus upper H subscript 2 upper O (g) right arrow upper C upper o (g) plus upper H subscript 2 (g).. To calculate the final enthalpy of the overall chemical equation, which step must occur?
Reverse the first equation, and change the sign of the enthalpy. Then, add.
Reverse the second equation, and change the sign of the enthalpy. Then, add.
Multiply the first equation by three, and triple the enthalpy. Then, add.
Divide the third equation by two, and double the enthalpy. Then, add.
Answer:
Hess's law:
First reaction:
Ca (s) + CO₂ (g) + ½O₂ (g) → CaCO₃ (s) ΔH₁ = -812.8 kJ
Second reaction:
2Ca (s) + O₂ (g) → 2CaO (s) ΔH₂ = -1269 kJ
Overall reaction:
CaO (s) + CO₂ (g) → CaCO₃ (s) ΔH = ?
According to the Hess law of constant heat summation, the enthalpy of the overall reaction is the sum of the enthalpy of both reactions but this will not give the enthalpy of the overall reaction in this case. The enthalpy of the overall reaction is rather obtained by halving the enthalpy of the second intermediate reaction and reversing its sign before taking the sum as shown below;
Enthalpy of Intermediate reaction 1 + ½(- Enthalpy of Intermediate reaction 2) = Enthalpy of Overall reaction

What are the two ways by which rock series are derived
The rock series can be classified into two major classes which include igneous rocks and sedimentary rocks.
What are Igneous rocks?Igneous rocks represent a specific series of rocks generated when magma cools to form solid rocks.
Conversely, sedimentary rocks form due to the deposition of different materials (e.g., due to precipitation).
In conclusion, the rock series can be classified into two major classes which include igneous rocks and sedimentary rocks.

Why do large-scale convection currents occur in the atmosphere?
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

Which description is true about the transformation shown?
It is a dilation because the transformation is isometric.
It is a dilation because the transformation is not isometric.
It is a stretch because the transformation is isometric.
It is a stretch because the transformation is not isometric.
Answer:
the answer is b
Explanation:
i just did the test on edge
It is a dilation because the transformation is not isometric is the description is true about the transformation shown. Hence, option B is correct.
Exercising or doing a series of exercises that include putting opposite muscles under tension to the point where there is little muscle shortening but a large increase in muscle tone.
An isometric exercise, to put it simply, involves contracting muscles without making them move. Instead, you adopt and stick with a single position. For instance, when completing a plank or a wall sit, the muscles are moving but not actively changing lengths.
Isotonic implies "same tension," but isometric means "same length," because the weight on your muscles remains constant. It's also critical to be aware that different exercises can be performed isometrically.
Thus, option B is correct.
