The correct answer is industrial smog. This type of smog exists in coal power plants which creates smoke and sulfur dioxide which may mix with fog creating a thick blanket of haze. Sulfur dioxide is one primary component of an industrial smog.
Question A is more testable through a scientific experiment because you have a specific thing you are trying to find out, "which gelatin takes longer to set".
PH stands for potential hydrogen.
pH can be accurately tested using acid-based indicators since it is a part of the pH of something itself. (acid and bases) The indicators themselves work when the acidic properties of the indicator begins to dissolve and form ions which gives the color indicating the pH.
Answer:
1) mass and volume
2) float.
3) Sink
4) Apples
5) Cannonball
Explanation:
1) Density is based on the mass and volume of a material.
2) A material or an object with low density than water or liquid tends to float.
3) A material or an object with high density than water or liquid tends to sink.
4) The apples in the water have less density as they are floating in the water.
5) The cannonball is more dense than the ocean water and the ball sink in the less density water.
Answer:
The answer to your question is: 0.015 mole of NO
Explanation:
Data
Silver = Ag = 0.1 mole
Nitric acid = HNO3 = 10 ml 6 M
Balanced reaction
3Ag + 4HNO₃ ⇒ 3AgNO₃ + NO + 2H₂O
# moles of HNO₃ = 6(0.01) = 0.06
Limiting reactant HNO₃ because for the amount of silver given
the reaction needs 0.133 moles of acid, and there
are only 0.06
4 mol of HNO₃ ------------------- 1 mol of NO
0.06 mol of Ag ------------------ x
x = (0.06 x 1) / 4
x = 0.015 mol
