It’s basically an educated guess, but not a far out stretched guess like say you were testing which baby birds could fly, you could make a guess by seeing how they work & conclude your answer. hope this helps!

Chlorine gas reacts with aluminum metal producing aluminum chloride. What mass of chlorine reacts with 9.00g of Al to form AlCl3
Anit [1.1K]
The  mass of  chlorine   that react  with  9.00 g  of Al to form AlCl3  is   35.465  grams

     Explanation
write  the equation  for  reaction
that is
2 Al +  3 Cl2  = 2 Al CL3
find  the moles  of    Al  reacted

moles = mass/molar mass

  9 g/ 27  g/mol = 0.333  moles  of Al

by use  of mole ratio between   Al to  Cl2    which is  2:3   find the moles of  Cl2

mole  of cl2 =  0.333 x3/2 = 0.4995  moles


mass of  Cl2  is therefore =  moles  x  molar mass

= 0.4995  x71 =  35.465  moles

Find the time Δt it takes the magnetic field to drop to zero. Express your answer in terms of some or all of the quantities a, B
Mekhanik [1.2K]
Δt= \frac{NB_0 \pi a^2 }{IR}

This because ε = dΦ/dt, and emf is a voltage so it can also be written as dΦ/dt = IR

Because ΔΦ= ABcosθ for each of the N loops and cosθ is just 1 here only A needs to be replaced, and it can be replaced with A=πr^2, which makes that part of the equation ΔΦ_m=N*B0*πa^2

Describe the properties of alkaline earth metals. Based on their electronic arrangement, explain whether they can exist alone in
zheka24 [161]

Answer: all i know about alkaline metals is he alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure.

All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge.

All of the alkaline earth metals except magnesium and strontium have at least one naturally occurring radioisotope.

Magnesium and calcium are ubiquitous and essential to all known living organisms.
