Alexandra [31]3 years ago
3 0

Answer:

Physical Properties:

  1. The grass is green.
  2. The wood on the house is brown.
  3. The house is solid.
  4. The stone on the house is dark grey.
  5. The trees are green.
  6. The glass in the windows is clear and colourless.

Chemical Properties:

  1. The wood is flammable.
  2. The stone is not flammable.

Explanation:

Physical properties are properties that don't require a chemical reaction to be measured, for example the colour. Chemical properties are properties that are observed when a substance undergoes a chemical reaction, for example flammability.

Witch wave is mad up of vibrating electric and magnetic fields that can move through space at the speed of light
8_murik_8 [283]

Answer:

Hiya! Your answer would be an Electromagnetic Wave.

Explanation:

Electromagnetic Wave is an electromagnetic wave that travels through space at the speed of light at about 300,000 kilometers per second. So when we talk about light traveling in waves, we can also talk about frequency, or the number of wavelengths that pass a certain point in a given length of time. We usually measure this as the number of wavelength cycles that pass per second. The units for this measurement are Hertz (hz).

So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. This means that more cycles can pass by the set point in 1 second. Likewise, a light wave that has a longer wavelength will have a lower frequency because each cycle takes a longer time to complete.

Hope I helped and I hope you get it right! :). Have a lovely day my friend!

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
