The answer is option e that is e. Iron and magnesium.
Dark silicates have a specific gravity of 3.2 to 3.6 and are composed primarily of silica tetrahedral and iron and magnesium.
Iron and magnesium is a component of dark silicates that have a specific gravity of 3.2 to 3.6.
So the answer is iron and magnesium.
2 and a half
250 x 2 =500
250/2=125
and 125 is a half of 250
so your answer is
2 and a half
C)shorter wavelength and higher energy
frequency is inversely proportional to wavelength
frequency is directly proportional to Energy
Hello!
The pressure of the gas when it's temperature reaches 928 °C is 3823,36 kPa
To solve that we need to apply
Gay-Lussac's Law. It states that the pressure of a gas when the volume is left constant (like in the case of a sealed container like an aerosol can) is proportional to temperature. This is the relationship derived from this law that we use to solve this problem:

Have a nice day!
