<h3><u>Answer;</u></h3>
Surface fire
<h3><u>Explanation;</u></h3>
- <u>Surface fires are type of forest fires that may burn primarily as a surface fire,</u> spreading along the ground as the surface litter and undergrowth on the forest floor and is engulfed by the spreading flames.
- They are the easiest fires to put out and cause the least damage to the forest. Surface fires create the least amount of destruction.
- <em><u>These fires protects the forest by releasing the nutrients that would otherwise decompose slowly, having little benefit to the ecosystem.</u></em>
- <em><u>Additionally, these fires allow more open spaces for new and different kinds of vegetation to grow and receive sunlight.</u></em>
Answer:
B
Explanation:
The mechanism of this process: the electrolytic cell converts the electrical energy to chemical energy, using external energy source.
Answer:
Explanation:
Hello.
In this case, given the chemical reaction, we can compute the grams of oxygen by using the 98.2 g of water via the 2:1 mole ratio between them, the molar mass of water that is 18.02 g/mol, the molar mass of gaseous oxygen that is 32.00 g/mol and the following stoichiometric procedure relating the given information:
In which the result is displayed with three significant figures because the given mass of water 98.2 g, has three significant figures too.
Best regards!
Answer: 1.284M NH3
Explanation: (12.23 grams)/(17.0 gramms/mole) = 0.7191 moles
Dissolved in 560.0 ml (=0.5600L)
(0.7191 moles)/(0.560L) = 1.284M (4 sig figs)
