Which chemical formula represents a polyatomic ion?
Answers
Answer:CIO^-
Explanation: just took the quiz, and I got it right
Polyatomic ions describes ions which are posses more than one atom. Hence, the formula which represents a polyatomic atomic ion is [tex]SO_{4}^{2-} [/tex]
Sulphates contain both Sulphur and Oxygen atoms, hence, they contain two atoms, thus they are polyatomic. Sulphide are represented as [tex]S^{2-} [/tex] ; containing only Sulphur atom, hence, they are mono atomic. Chlorides are represented as [tex]Cl^{2-} [/tex] ; containing only chlorine atoms, hence, they are mono atomic. Nitrides are represented as [tex]N^{3-} [/tex] ; containing only Nitrogen atom, hence, they are also mono atomic.Therefore, sulphates are polyatomic as they contain more than one atom.

a pedometer treats walking 1 step as walking 2.5 feet. define a function named feet_to_steps that takes a float as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. then, write a main program that reads the number of feet walked as an input, calls function feet_to_steps() with the input as an argument, and outputs the number of steps.
Answers
The required program written in python 3 defines a function which converts the number of feets walked into steps and returns an integer value for the number of steps. The program goes thus :
def feet_to_steps(feet):
#initialize a function called feet_to_steps
num_steps = feet / 2.5
#divide the number of feets by 2.5 and assign the number of steps to the variable num_steps
return round(num_steps)
#return the rounded integer value of num_steps
your_feet = eval(input('Enter feets number of feets walked : '))
#prompts the user to input a float value for the number of feets
#A sample run of the program is given below and attached.
print(feet_to_steps(your_feet), ' steps')

a ball is thrown straight downward with a speed of 0.80 meters per second. what is the speed of the ball 0.60 seconds after it is released? [ignore air resistance.]
Answers
The speed of the ball 0.60 seconds after it is released is 6.8 m/s.
Newton's law of motion is given by:
v = u + gt
where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and t is the time.
Given that:
u = 0.8 m/s, g = 10 m/s², t = 0.6s. Hence:
v = 0.8 + 10(0.6)
v = 6.8 m/s
Therefore the speed of the ball 0.60 seconds after it is released is 6.8 m/s.

generally reduces the number of hurricanes formed in the atlantic ocean results in a more active tornado season can lead to crop damage and landslides in california
Answers
Based on meteorological information El Nino generally reduces the number of hurricanes formed in the Atlantic ocean.
This is because the impact of El Nino quells the Atlantic hurricane effect. This is done by raising the quantity of sinking motion and improving atmospheric resilience.On the other hand, La Nina results in a more active tornado season.
This is because the La Nina effect pushes the jet stream to move towards the north, and subsequently, this effect reduces around the Pacific side.Excessive rainfall can lead to crop damage and landslides in California.
This is because continuous rainfall at a certain level in California leads to erosion which can damage crops. Subsequently, continuous rainfall of about two weeks can turn erosion into landslides in California, particularly the southern side.Hence, in this case, it is considered that different climatic conditions affect the physical environment of humans.
