Answer:
Plants
Explanation:
Animals and decomposers do not go through the process of photosynthesis. Animals do not make their own food like plants do, and decomposers feed on matter that is decomposing. Hope this helped :)
Ik it's not magnesium because that was my first answer. The correct answer would be Sulfur. Sulfur is a non metal. All the other answers are good conductors of heat
Answer:
1.40 atm
Explanation:
To answer this question we can use<em> Gay-Lussac's law</em>, which states:
When volume and number of moles remain constant.
- T₁ = 23°C ⇒ 23+273.16 = 296.16 K
- T₂ = Boiling point of water = 100 °C ⇒ 100+273.16 = 373.16 K
We <u>put the known data in the equation and solve for P₂</u>:
- 1.11 atm * 373.16 K = P₂ * 296.16 K
Answer:
O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.
<span>Sodium carbonate (Na2CO3) reacts with acetic acid (CH3COOH) to form sodium acetate (NaCH3COO), carbon dioxide (CO2), and water (H2O). A chemist carries out this reaction in a bomb calorimeter. The reaction causes the temperature of a bomb calorimeter to decrease by 0.985 K. The calorimeter has a mass of 1.500 kg and a specific heat of 2.52 J/g K. What is the heat of reaction for this system? What equation should I use in this case? I've written down these notes: Steps: 1. Calculate the mass of the solution in total. 2. Convert mass to volume or vice versa if needed. 3. Calculate the temperature change of the solution. 4. Calculate the energy released by the reaction.</span>
