Answer:
nonmetals
Explanation:
nonmetals nonmetals receive more because metals are much harder to gain than nonmetals.
Answer:
Scientific reasoning (SR), broadly defined, includes the thinking skills involved in inquiry, experimentation, evidence evaluation, inference and argumentation that are done in the service of conceptual change or scientific understanding.
They mimicked the flight of birds.
Answer:
1.878g
Explanation:
Volume = 30.0ml
Density = 0.626gcm−3
Mass = ?
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³ so density = 0.626g/ml
The relationship between all three parameters is given by the equationn below;
Mass = Density * Volume
Mass = 0.626g/ml * 30 = 1.878g
The total pressure of the flask is sum of partial pressures of the gases present in a mixture of gas
This is Dalton's law of partial pressures .'
say we have a mixture of "n" gases with respective pressure : P1, P2 ...Pn
total pressure of the gases = P1 +P2 + P3 + ...Pn = Ptotal
So in the given problem the total pressure of flask will be = 0.72+1.65 = 2.37 atm
