Any mixture that looks the same through the substance is homogenous. The different parts are unable to be visibly seen. (Any periodic element is homogenous)
Any mixture that can be easily determined a mix and cannot be evenly separated or dispersed is heterogenous.
Answer:
1.54 atm
Explanation:
By Dalton's Law Of partial pressure,
Total Pressure = Sum of all partial pressures
So,P= P1 + P2 + P3
Therefore, P=0.23+0.42+0.89
=1.54 atm
Here is what Golgi looks like, so that you can look at the picture and describe it.

There are 2 moles of O stones present in 88 grams of CO2. Why? Well, we can find the amount of moles present in 88 grams of CO2 by dividing the mass by the molar mass. The mass of CO2 comes out to be 88 grams. The molar mass of CO2 comes out to be 44 grams. Because 88 is the mass of CO2 and 44 is the molar mass of CO2, we can divide 88 by 44 to identify that there are 2.0 moles of O atoms present in 88 grams of CO2.
Your final answer: There are 2.0 moles of O atoms present in 88 grams of CO2. Your final answer to this question is D, or 2.0 moles. If you need to better understand, let me know and I will gladly assist you.
Answer:
3. Inverse 1. Direct
Explanation:
P- pressure
V - volume
T - temperature
P1*V1 / T1 = P2*V2 / T2 ...... (1)
That's the general gas law with the combined ideas of charles, boyle & lussac.
Whenever you are restricted as "constant" temperature, volume, or pressure...cancel them off of your equation.
in this case 3. is indirectly telling us to cancel the temperature (T).
so we'll be left w P1*V1 = P2*V2
now notice that any relation ship that is multiplied like the one above consists of inversely related quantities. & so we conclude that-
P & V are inversely proportional or have an inverse relationship.
similarly in 1. we'll cancel p off of the general formula (1)
to be left with V1/T1 = V2/T2
also note that quantities involved in division are directly related to each other & hence the answer.
