Homogeneous because everything is mixed together evenly.
Answer:
See explanation
Explanation:
distance = 3 kilometres
time = 30 minutes or 0.5 hours
speed = distance/time = 3/0.5 = 6 Kmhr-1
Average speed is given by total distance covered divided by the total time taken while the instantaneous speed is the speed of an object at a particular instant or moment in time. Average speed refers to the whole journey while instantaneous speed refers to a particular point or instant in the journey.
distance= x
time = 3 hours
speed = 50 miles per hour
speed = distance/time
distance = speed * time
distance = 3 * 50
distance = 150 miles
Answer:
If you are given a chemical equation and specific amounts for each reactant in grams, you have to follow these steps, in order, to determine how much product can possilby be made:
1. Convert each reactant into moles of the product.
2. Determine which reactant is the limiting reactant.
3. Convert the moles of product, from the limiting reactant, to grams.
Explanation:
Answer:
3.076 L.
Explanation:
- The pressure is constant as it is the atmospheric pressure.
- According to Charles’ law; at constant pressure, the volume of a given quantity of a gas varies directly with its temperature.
∴ V₁T₂ = V₂T₁.
V₁ = 2.6 L & T₁ = -11 °C + 273 = 262 K.
V₂ = ??? L & T₂ = 37 °C + 273 = 310 K.
∴ V₂ = (V₁T₂) / T₁ = (2.6 L)(310 K) / (262 K) = 3.076 L.
Answer:
The statement which describes an intensive property of matter is - :
<u>it is the same for every sample of a single substance.</u>
Explanation:
- <u>It is the same for every sample of a single substance. -:</u> Since a substance 's intense property does not depend on either mass or volume, it is the same for each sample of a single substance. <u>Hence , this statement is correct .</u>
- <u>It depends on how a substance was formed -:</u> Intensive property do not depend upon the amount of the substance or the formation of the sample . <u>Therefore this statement ifs wrong about intensive property .</u>
- <u>It is the same for every sample of every substances -: </u> This is not possible to be for every sample of the substance , a every substance have different qualities. <u>Hence this statement is also incorrect.</u>
- <u>it depends on the amount of substances present -: </u> This is the characteristic of a extensive property of matter that relies on the amount of the material/substance.<u> This assertion is, therefore, not valid.</u>
Hence ,<u> the correct option is A (it is the same for every sample of a single substance).</u>
