The total mass of heterogenous mixture is 183.68g
A combination is said to be heterogeneous if its composition is not constant throughout. A phase is any area of a sample with a consistent composition and set of characteristics. A heterogeneous mixture is one that has two or more phases by definition. When water and oil are combined, they do not mix equally but rather split into two layers.
A phase is the name given to each layer. Around us, there are a lot of heterogeneous mixtures. Different chemicals make up soil, and the composition might vary based on the sample that is obtained. The first shovelful might turn up soil and grass, while the second shovelful might come up with an earthworm. Another illustration of a heterogeneous combination is smog
The total mass of heterogenous mixture is = 139. 32 grams sand + 34. 99 grams gravel + 9. 372 grams salt.
The total mass = 139.32+34.99+9.372
The total mass = 183.68g

Hello!
When you are honestly reporting experimental findings, you are using good ethics.
Ethics are moral principles that a person has, that allows for us understand and conduct certain behaviors. So when you are being honest, you are having good morals, or good ethics because you are sticking to the truth even though you could lie about your findings to get a certain result.
Hope this helps answer your question!
Answer:
26 g
Explanation:
Write the balanced reaction first
CH4 + 2 O2 --> CO2 + 2 H2O
9.3g + 52.3g --> ? CO2
You must determine how much carbon dioxide can be made from each of the reactants. The maximum mass that can be made is the lower of the two.
From CH4:
9.3g CH4 (1molCH4/16.05gCH4) (1molCO2 / 1molCH4) (44.01g CH4 / 1molCO2) = 26 g
From O2:
52.3g O2 (1molO2/32gO2) (1molCO2/2molO2)(44.01g/1molCO2) = 36 g
It is a physical change: A chemical change would be if...there was bubbles, smoke, etc... A physical change is if it changes color, odor, shape, other PHYSICAL appearances.
