Answer:

Positive Geotropism means growth of the plants towards the Gravitational force. e.g.It means When a plant's root grows towards Gravitational force . It is positive geotropism. Negative Geotropism means growth of the plant against the Gravitational force. e.g. When a plant's steam grows towards sunlight.

A 50.0 mL of 0.88 M H2O2 and 10.0 mL of 0.50 M Fe(NO3)3 were combined and a temperature change of 7.47 was observed. The specifi
Shtirlitz [24]

Answer:

The heat of reaction -1.9 kilo Joules.

Explanation:

Volume of the hydrogen peroxide solution = 50.0 mL

Volume of the ferric nitrate solution = 10.0 mL

Total volume of the solution = 50.0 mL + 10.0 mL = 60.0 mL

Mass of the final solution = m

Density of water = density of the final solution = d = 1 g/mL

Mass=density\times Volume

m=1 g/ml\times 60.0 ml=60.0 g

Heat capacity of the mixture = c = 4.18 J/g°C

Change in temperature of the mixture = ΔT = 7.47°C

Heat absorbed by the mixture = Q

Q=mc\Delta T

Q=60.0 g\times 4.18 J/g ^oC\times 7.47 ^oC=1873.48 J=1.873 kJ\approx 1.9 kJ

Heat release due to reaction = -Q'

-Q' =Q (law of conservation of enrage)

Q'= -Q = -1.9 kJ

The heat of reaction -1.9 kilo Joules.

What does polar and nonpolar mean in science
MissTica

Polar molecules are molecules are essentially have no molecular symmetry. 

Nonpolar molecules are molecules that have molecular symmetry.

Water is a very basic example of a polar molecule.
