When mixed, which states of matter form only a homogeneous mixture?A.two liquids
B.two gases
C.a solid and a liquid
D.a liquid and a gas
Answers
The correct answer is b. two gases
The explanation:
-Mixtures can be either homogeneous or heterogeneous. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.\
- Examples of homogeneous mixtures include alloys and alcohol in water. A heterogeneous mixture is a type of mixture in which the components can be seen.
-One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.
Answer: B.two gases
Explanation: Homogeneous mixtures are mixtures in which dispersed phase is uniformly distributed throughout the dispersion medium and there is no physical boundary between the dispersed phase and dispersion medium.
Heterogeneous mixtures are mixtures in which dispersed phase is not uniformly distributed throughout the dispersion medium and there is a distinct physical boundary between the dispersed phase and dispersion medium.
a) Two liquids may or may not be completely miscible thus may form a homogeneous (milk and water) or a heterogeneous mixture (oil and water).
b) Two gases always form a homogeneous mixture as there is large vacant spaces present between the molecules.
c) A solid and a liquid may or may not be completely miscible thus may form a homogeneous (salt and water) or a heterogeneous mixture ( sand and water).
d) A liquid and a gas may or may not be completely miscible thus may form a homogeneous (river water) or a heterogeneous mixture (perfume spray).

Explanation:
The formula of water is H₂O.
1. Calculate the molar mass of water
2 H = 2 × 1.008 = 2.016 u
1 O = 1 × 16.00 = 16.00 u
MM = 18.02 u
2. Mass of hydrogen
\text{Mass of H} = \text{92.0 g water} \times \dfrac{\text{2.016 g H}}{\text{18.02 g water }} = \textbf{10.29 g H}
3. Mass of 0xygen
Final answer:
A 92 gram sample of water will consist of approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.
Explanation:
Water
consists of two hydrogen atoms and one oxygen atom. Therefore, it has a
molecular formula of H2O
. To find the mass of each element in a 92 gram sample, we need to know the molar mass of the elements and the compound. The molar mass of hydrogen (H) is about 1 gram per mole, and oxygen (O) has a molar mass of 16 grams per mole. So, the molar mass of water (H2O) is approximately 18 grams per mole (2*1 + 16). This means that in one mole of water, 2 grams are hydrogen and 16 grams are oxygen. If we scale this up to 92 grams, we find that there are approximately 10.22 grams of hydrogen and 81.78 grams of oxygen.

The difference between light reflection and refraction is simple. In reflection, the light ray striking the plane returns to the originating source or medium as the waves spring off the surface. in refraction, the waves go through the surface and it alters their speed and direction.
what is reflection?
Reflection is the bouncing back of light when it strikes a smooth surface. Generally occurs on shinny surfaces that only allow rebounding of light without permitting penetration through it. In this process, light bounces back and returns back in the same direction.
Refraction is the bending of light rays when it travels from one medium to another. This occurs in transparent surfaces that allow bending of the ray to a different medium.
In this process, light changes path i.e travels from one medium to another.

Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering from an angle will change direction
Rarefraction refers to the "bending of wavelengths around an edge"of an object. diffraction depends on the size of the object relative to the wavelength of the waves.
