A reaction occurs in a calorimeter, resulting in the starting and final temperatures shown below. What can you say about the rea
Pavlova-9 [17]

Answer:

The reaction is exothermic and ΔH is negative

Explanation:

An exothermic reaction is a chemical reaction that releases energy in the form of heat. It is the opposite of an endothermic reaction in which energy is absorbed. It is expressed in a general thermochemical equation: reactants → products + energy.

We can know that a reaction is exothermic by observing the calorimeter to know if there is an increase in temperature. Remember that an exothermic reaction leads to evolution of heat. This is observed physically as a rise in temperature.

The calorimeter initially read 21.0 and finally read 38.8 at the end of the reaction. This implies that heat was given out in the process. The reaction is exothermic and ∆H is negative.

Is an example of the carbon cycle occurring slowly?(1 point)
o-na [289]

Decomposition is a part of the carbon cycle that occurs slowly hence  movement of carbon dioxide into the atmosphere when bacteria decomposes dead matter is a slow part of the carbon cycle.

<h3>What is the carbon cycle?</h3>

The carbon cycle is part of the biogeochemical cycles that exist in nature. It refers to the movement of carbon in the ecosystem. The carbon cycle cuts across the air, the land and the water bodies.

The process in the carbon cycle that occurs slowly among the options is the movement of carbon dioxide into the atmosphere when bacteria decomposes dead matter.

Put the steps in process of photosythensis order
arlik [135]

Answer:

Step 1- CO2 and H2O enter the leaf.

Step 2-  Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

Step 3- The electrons move down to enzymes.

Step 4-Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

Step 6-The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

Step 7-calvin cycle. The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.

Hope this helps : D
