Homogeneous materials look the same throughout even throughout even though they contain different materials. a. true b. false

Homogeneous materials look the same throughout even throughout even though they contain different materials.  --> A. True <--

Answer : The statement is true.

Explanation:

Mixture : It is defined as a substance that has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.

There are two types of mixture.

Homogeneous mixtures : It is defined as a mixture which has uniform composition throughout the solution that means it looks the same throughout the evenly though they contains different materials. The particle size or shapes are not different.

There is a no physical boundary between the dispersed phase and dispersion medium.

Heterogeneous mixtures : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different.

There is physical boundary between the dispersed phase and dispersion medium.

Hence, the given statement is true.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

the maximum mass of nh3 is nh3 in grams
