I have posted this question before and I have waited for 3 hours and no one is helping me. Please help me. I have 2 questions.
1.state whether each substance is a mechanical mixture, a suspension, or a solution. My answers are at the bottom.
a)green relish
b)soda pop in a glass
c)bubble tea
d)traditional Aborigial paint made of red orchre and grease
my answers=
a)suspension
b)solution
c)suspension
d)mechanical mixture
2.suppose that you dissolve 250ml of drink crystals in 1000ml of water. You get 1175ml of drink rather than 1250ml. how can you use the partical model of matter to explain this?
I apologize for the delay in response. Let me help you with your questions:
1. Determining the nature of substances:
a) Green relish: Green relish typically consists of chopped pickles in a solution of vinegar or brine. Therefore, it is a solution.
b) Soda pop in a glass: Soda pop is a carbonated beverage that contains dissolved gas bubbles. It is a solution.
c) Bubble tea: Bubble tea is a popular drink containing tea, milk, sweeteners, and tapioca pearls. The tapioca pearls are suspended in the drink, making it a suspension.
d) Traditional Aboriginal paint made of red ochre and grease: Aboriginal paint made of red ochre and grease is a mixture where solid particles of red ochre are mechanically dispersed in the grease, making it a mechanical mixture.
Your answers for the first question are as follows:
a) Solution
b) Solution
c) Suspension
d) Mechanical mixture
2. Explaining discrepancy in volume using the particle model of matter:
When you dissolve drink crystals in water, the particles of the crystals mix with the water particles. According to the particle model of matter, particles can occupy space. In this case, the dissolved particles occupy space between the water particles, causing an increase in volume.
However, it is important to note that the actual volume increase may vary depending on various factors such as the specific properties of the drink crystals and the water, as well as any chemical reactions taking place.
