Do you know about the wallaby? The Wallaby is an animal that looks like a kangaroo. Though they have many similarities with the kangaroo, they are slightly different from the kangaroo. Most common way to distinguish the difference between the wallaby and kangaroo is their size. The Wallaby is much smaller than the kangaroo. Their heights are about 30 to 180 and they weight about 20kg. They can run up to 48kms per hour and live from 12 to 15 years. (Anonymous, no date) The Wallaby belongs in

many other factors (Fox). Temperature is one of the most important since the higher temperatures increase the rate of the reaction as well as accelerate the evaporation of the water the process generates (Myhrvold), meaning that this reaction is endothermic. The exact reactions are hard to control, which is why every batch of cookies turn out a little differently. The products of these reactions can also react with each other leading to even more diversified and complex taste and smells.

In this lab, Le Chatelier’s Principle was observed by shifting different equilibriums to the left or right in order to make the colors of the rainbow. The equilibrium shift could be identified by the colors of the solution. In the tray 5 experiment, the reactant was pink and the product was a dark blue color. After stressing the equilibrium, a pink color indicated that the equilibrium was shifted to the left, and a blue color indicated that the equilibrium was shifted to the right. The stresses

metal clump. After the reaction, zinc was still reusable and it produced a gas. One can predict that single replacement will occur because there is one element on its own. In station 4, Zn(C2H3O2)2 (aq) + 2Na Po4 (aq) Zn(Po4)2 + 2NaC2H3O2 (aq) is endothermic and is a double replacement. A double-replacement reaction involves two aqueous solutions the cation and anions stitch to form a new reaction. The zinc acetate and the sodium phosphate combine and the Zinc switches places with the sodium creating

is maintained in the body, but if an enzyme is lacking or has a shape that is not right due to a genetic mutation, it can lead to diseases within an organism. The equation for this reaction is 2H2O2→2H2O+O2. An endothermic reaction is one that needs to be supplied with heat. Endothermic reactions are like an opposite of an exothermic reaction. Instead

Introduction: This experiment is focused on heat of combustion using hydrocarbons as fuel. All three fuels produce combustion reactions which are exothermic. When bonds are formed or broken the most common form of energy released or taken in is heat energy. Heat of combustion is a way of measuring how much energy is output from a combustion reaction, the energy that is output is usually in the form of heat. Figure 1.

Name Chemistry 131L Lab #7 – Thermochemistry: Heat of Reaction Abstract The main objective of this experiment was to calculate the enthalpy of the reaction for the decomposition of hydrogen peroxide as well as measure the heat capacity in regard to the neutralization of a strong base and strong acid. Additionally, data was graphed in order to find the change in time relating to temperature vs. time. A calorimeter was made so that the temperatures of these reactions could be monitored and recorded

Lithium is a metal, so it would’ve had an endothermic reaction, and gained energy to perform electron affinity. This would be because, in a metal element, when an electron is added to the valence shell it would make an endothermic reaction so energy is needed to sustain that electron. (Harwood, 2016) Furthermore, there are only 2 shielding electrons in Lithium, this would mean Lithium

In this experiment, the heat neutralization of HCl-NaOH and HNO3-NaOH was determined. To obtain the more accurate data, two trials of each reaction were carried out. For the HCl-NaOH reaction, the heat neutralization was -53.699 KJ/mol for the first trial, -54.363 KJ/mol for the second trial and -54.031 KJ/mol for their average. The percent error calculated in this reaction was 4.74%. Moreover, for the HNO3-NaOH reaction, the heat of neutralization was -55.487 KJ/mole for the first trial, -53.445

(cold-blooded) crocodiles have very limited needs for food (they can survive several months without eating) while endothermic (warm-blooded) animals of similar size need much more food in order to sustain their faster metabolism. Therefore, under the circumstances of food chain disruption previously mentioned, non-avian dinosaurs died while some crocodiles survived. The survival of other endothermic animals, such as some birds and mammals, could be due, among other reasons, to their smaller needs for food
