Answer:
The correct answer is option B.
Explanation:
Endothermic reactions are defined as the reactions in which energy of products is more than the energy of the reactants. In these reactions, energy is absorbed by the system.
The total enthalpy of the reaction 
comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of reactants is more than the energy of the products. In these reactions, energy is released by the system.
The total enthalpy of the reaction comes out to be negative.
On mixing of both solution we had observed that temperature of the resulting solution was lowered this is because the energy was absorbed during the chemical reaction.
Answer:
Some human activities that contribute to climate change would be fracking, driving vehicles, deforestation, and developing cities. Fracking releases methane and other greenhouses gases into the atmosphere. Driving vehicles, like cars or trains, also releases carbon dioxide into the atmosphere. Deforestation decreases the amount of oxygen being produced. Developing cities also contributes because it consumes almost 80% of the world's energy, as well as producing 60% of the greenhouse gases.
Carbohydrates, proteins, lipids, and Nucleic Acids.
Answer:
0.635 cm³
Explanation:
You divide the mass by the density of iron (7.87 g/cm³)
<em>D = m</em>/<em>V</em> Multiply both sides by V.
<em>DV = m</em> Divide both sides by D.
<em>V</em> = <em>m</em>/<em>D</em> Insert the values.
<em>V </em>= 5.00/7.87 Do the division.
<em>V</em> = 0.635 cm³
