Write procedural steps that allow you to demonstrate the sun's role in the water cycle using common material - for each explain what you are modeling and how the materials you have chosen represent nature.
Using the accepted value for the volume of 1 gram of water at the temperature of the room that you reported above, what is the accepted value for the density of water
Answer:
The sentences which are made by the given sentences are as :
Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
Explanation:
Here in the question it has been mentioned to form the sentences with the given one:
- Wind speeds are below 38 miles per hour, this feature represents the tropical depression.
- A tropical disturbance leads to an array of clouds which are disorganized also there are thunderstorms with no rotation or little rotation with it.
- When the winds are blowing at a speed of 38 and 74 miles per hour then it is called as a tropical disturbance.
- 74 miles per hour should be the blowing speed of storm in order to consider it to be a Hurricane.
- When the storm reaches a tropical storm stage it gets its name.
- All of the storms which get occurred from time to time, among them half or even all get converted into a Hurricane.
These are the sentences which are made by exploring the whole process and by which a storm becomes a Hurricane.
Answer:
120g
Explanation:
Step 1:
We'll begin by writing the balanced equation for the reaction.
Sn + 2HF —> SnF2 + H2
Step 2:
Determination of the number of mole HF needed to react with 3 moles of Sn.
From the balanced equation above,
1 mole of Sn and reacted with 2 moles of HF.
Therefore, 3 moles Sn will react with = 3 x 2 = 6 moles of HF.
Step 3:
Conversion of 6 moles of HF to grams.
Number of mole HF = 6 moles
Molar Mass of HF = 1 + 19 = 20g/mol
Mass of HF =..?
Mass = number of mole x molar Mass
Mass of HF = 6 x 20
Mass of HF = 120g
Therefore, 120g of HF is needed to react with 3 moles of Sn.

Answer:
pOH is 2.2
Explanation:
The pH scale goes from 0 to 14. As such, the pH and the pOH add up to 14. Subtract your pH from 14 to get your answer.
14 - 11.8 = 2.2
