What are the disadvantages of driverless cars ? Check all that apply

vladimir1956 [14]

Computers don’t have the ability to see as much as we do and in Construction sites this can be very dangerous if your driverless car has not been properly updated in an area where there’s a lot of construction you can we put into harms way. The lanes may have changed and they will not have the data to be able to recognize this in time and you could get into a serious car crash.

Based on lewis structure analysis, what is the formal charge of the central atom in clf3

MArishka [77]

Formal Charge is calculated as, Lewis structure is attached below,

Formal Charge = [# of valence electrons] - [electrons in lone pairs + 1/2 the number of bonding electrons]

# of valence electrons of Cl = 7

electrons in lone pairs = 4

number of bonding electrons = 6

Formal Charge = [7] - [4 + 6/2]

Formal Charge = [7] - [4 + 3]

Formal Charge = [7] - [7]

Formal Charge = 0

Result:
Formal charge on Cl in ClF₃ is zero.

You know that chemical a reacts with chemical

Jet001 [13]

The chemical reaction would most likely be written as follows:
A + B = AB
We cannot simply use the usual method of converting grams to moles since we do not have any idea on what are the identities of A and B. The only method we could use is to use the law of conservation of mass where mass inflow in a process should be equal to the mass out in the process. The total inflow of mass would be the mass of A and B and the outflow would be the product AB.

mass of A + mass of B = mass of AB
10.0 g A + 10.0 g B = mass of AB
mass of AB = 20.0 g

All of the above

Natalka [10]

The plants without any fertiliser could be the control, to see what the change in the independent variable (fertiliser) does to the growth of the plant (dependant variable).

Hope that helps.
