The most brittle one is selenium!
Explanation:
pls the question is not clear to me
Answer:
0.2886 atm is the osmotic pressure of a solution.
Explanation:
Osmotic pressure of solution =
Concentration of the solution = c
Mass of the ammonium sulfate = 1.502 g
Moles of ammonium sulfate =
Volume of the solution = 1 L
Concentration of the solution:
Temperature of the solution ,T= 36.54°C = 309.69 K
R = universal gas constant = 0.08206 L atm/mol K
0.2886 atm is the osmotic pressure of a solution.
Answer:
acceleration: 5 mi/h/s north
Explanation:
A quantity can be either vector quantity or scalar quantity, a vector quantity is a quantity with both magnitude and direction while a scalar quantity has magnitude only.
Examples of vector quantities include; velocity, acceleration, displacement , etc.
Acceleration is the rate of change of an object's velocity per unit of time. It is given by the formula; Velocity/time
Therefore in this case; a = 30 mi/h /6 s
= 5 mi/h/s
Therefore;
Acceleration = 5 mi/h/s
Answer:
CH₄ and N₂O are not likely to be biologically important greenhouse gases for tree growth
Explanation:
From the discussion of the experiment testing the given hypothesis in the question, all the gases tested, CO2, N2O and CH4 are all green house gases. The aim of the experiment was to ascertain the impact of the selected greenhouse gases on plant biomass. It was observed that CO2 does lead to increase in plant biomass while N2O and CH4 did not.
A proper deduction from the experiment will be 'CH₄ and N₂O are not likely to be biologically important greenhouse gases for tree growth'.
