example best shows that the chemistry of water is helpful to plants? Water’s polarity produces a high density, which allows wate

r to move to the leaves. Water’s bent shape causes a slow passage of nutrients up to the leaves of plants. Water’s polarity causes cohesion that pulls other water molecules up through a plant. Water’s bent shape reduces its own passage through the cell membranes of roots.

What is the specific heat capacity of a metal if it requires 177.5 J to change the temperatures of 15.0g of the metal from 25.00
Vikentia [17]

Answer:

The specific heat capacity of a metal is 1.31 J/g°C = C

Explanation:

A classical excersise of calorimetry to apply this formula:

Q = m . C . ΔT

177.5 J = 15 g . C (34°C - 25°C)

177.5 J = 15g . 9°C . C

177.5 J /15g . 9°C = C

1.31 J/g°C = C

PLSSSSS HELP I DONT GET THIS PROBLEMMMM
Aleks [24]

Answer:

C. 7370 joules.

Explanation:

There is a mistake in the statement. Correct form is described below:

<em>Using the above data table and graph, calculate the total energy in Joules required to raise the temperature of 15 grams of ice at -5.00 °C to water at 35 °C. </em>

The total energy needed to raise the temperature is the combination of latent and sensible heats, all measured in joules, and represented by the following model:

Q = m\cdot [c_{i} \cdot (T_{2}-T_{1})+L_{f} + c_{w}\cdot (T_{3}-T_{2})] (1)

Where:

m - Mass of the sample, in grams.

c_{i} - Specific heat of ice, in joules per gram-degree Celsius.

c_{w} - Specific heat of water, in joules per gram-degree Celsius.

L_{f} - Latent heat of fusion, in joules per gram.

T_{1} - Initial temperature of the sample, in degrees Celsius.

T_{2} - Melting point of water, in degrees Celsius.

T_{3} - Final temperature of water, in degrees Celsius.

Q - Total energy, in joules.

If we know that m = 15\,g, c_{i} = 2.06\,\frac{J}{g\cdot ^{\circ}C}, c_{w} = 4.184\,\frac{J}{g\cdot ^{\circ}C}, L_{f} = 334.72\,\frac{J}{g}, T_{1} = -5\,^{\circ}C, T_{2} = 0\,^{\circ}C and T_{3} = 35\,^{\circ}C, then the final energy to raise the temperature of the sample is:

Q = (15\,g)\cdot \left[\left(2.06\,\frac{J}{g\cdot ^{\circ}C} \right)\cdot (5\,^{\circ}C)+ 334.72\,\frac{J}{g} + \left(4.184\,\frac{J}{g\cdot ^{\circ}C}\right)\cdot (35\,^{\circ}C) \right]

Q = 7371.9\,J

Hence, the correct answer is C.

Which of the following statements is true about aquaculture? A. An aquaculturist can throw some young shrimp in a pond, and they
Delvig [45]

B. Aquaculture means "cultivating small acreages of land."

Explanation:

Aquaculture is the growing of fishes, crustaceans, molluscs, oysters and other marine organisms like algae in a small acreage of farm. Normally, the carryign capacity per acreage would be lower in the natural habitat – like in the oceans- but this is raised substantially in aquaculture due to adopting certain farming techniques. An example is by cycling the wastewater from teh fish tanks to plants that take up the waste as nutrients and oxygenate the water, The water is then recycled back to the tanks as cleaner water reusable by the fishes and teh cycle continues. This cycle ensures the sustainability of the farm even with very little water compared to the natural environment.
