Answer:
D
Explanation:
Scientific laws describe how things work with little to no exception. They do NOT provide an explanation to WHY something occurs.
Answer:
Velocity = wavelength x frequency
Wavelength = Velocity / frequency
From the above,
Wavelength is inversely proportional to frequency since the velocity of electromagnetic wave is constant.
So as the wavelength increases, the frequency decreases and vice versa
Answer:
The answer is 375.54 g of AgBr
Explanation:
Mass (g) = Concentration (mol/L) x volume (L) x Molecular Weight of AgBr (g/mol)
Mass = 2M x 1L x 187.77 g/mol
Mass = 375.54g
Explanation:
- A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed into a solvent.
For example, iced tea with no ice is a homogeneous mixture.
Also, a cheddar cheese contains even distribution of solute particles. Hence, it is also a homogeneous mixture.
- On the other hand, a mixture in which solute particles are unevenly distributed in a solvent is known as a heterogeneous mixture.
For example, both rocky road ice cream and trail mix are heterogeneous mixture.
