Ayala is making salad dressing. She mixes oil and vinegar in a blender until a smooth consistency is formed. Explain whether this is a heterogeneous or a homogeneous mixture and why.
Answers
Answer 1
Answer:
The correct answer would be homogeneous mixture. There are two types of mixture depending on the distribution of the components in the mixture. Homogeneous mixtures are mixtures which has uniform properties all throughout the mixture. For this case, the mixture of oil and vinegar had already achieved a uniform consistency.
Answer 2
Answer:
Correct Answer: Mixture will be heterogeneous
Reason:
The mixture is said to be homogenous, if it contains single phase, On other hand, heterogenous system has, multiple phases. When, oil and vinegar are mixed together, on standing, the two liquids separates out as different phases. Hence, the mixture will be refereed as heterogeneous.

Answer:
The mass of 2 moles of NO₂ is 92 grams.
Explanation:
Given that,
Number of moles, n = 2 moles
We need to find the mass of 2 moles of NO₂. We know that the number of moles is given by the formula as :
m is the given mass
M is the molar mass of NO₂,
So, the mass of 2 moles of NO₂ is 92 grams. Hence, this is the required solution.
Molar mass NO₂ = 46.0 g/mol
1 mole -------- 46.0 g
2.0 moles ----- ?
Mass (NO₂) = 2.0 x 46.0 / 1
=> 92.0 g
hope this helps!
