Taking into account the definition of calorimetry and latent heat, 11,690 J is required to change 35 g of water from ice to liquid water.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

Latent heat is defined as the energy required by a quantity of substance to change state.

When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.

The heat Q that is necessary to provide for a mass m of a certain substance to change phase is equal to

Q = m×L

where L is called the latent heat of the substance and depends on the type of phase change.

In this case, you know:

Replacing in the definition of latent heat:

Q = 35 g× 334 [tex]\frac{J}{g}[/tex]

Solving:

Q= 11,690 J

Finally, 11,690 J is required to change 35 g of water from ice to liquid water.

Answer:

An ecosystem is defined by the interactions between the living and non-living things in any given area. Abiotic factors are the non-living components of an ecosystem. These include: air water, wind, soil, temperature, sunlight. One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis , the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.

There are four main types of species interactions that occur between organisms in an ecosystem:

Predation , parasitism and herbivory – In these interactions, one organism benefits while the other is negatively affected.

* Competition – Both organisms are negatively affected in some way due to their interactions.

* Commensalism – One organism benefits while the other is neither harmed nor gains.

* Mutualism – Both organisms benefit from their interactions.

Plants with bird or butterfly pollinators are good examples of mutualistic interactions. Plants benefit by having their flowers pollinated so they can reproduce.

The graph of the heating of methanol has been attached.

The temperature at 170 K is approximately the melting point of methanol.

The temperature at 350 K is approximately the boiling point of methanol.

If we provide heat before 170 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in solid form.

If we provide heat at 170 K temperature then all the heat provided to the methanol will result in change in physical from of methanol from solid to liquid.

If we provide heat after 170 K temperature and before 350 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in liquid form.

If we provide heat at 340 K temperature then all the heat provided to the methanol will result in change in physical from of methanol from liquid to gas.

If we provide heat after 350 K temperature then all the heat provided to the methanol will result in rise in temperature of methanol in gas form.

So, the heat given to methanol will rise its temperature except at its Boiling and melting point. At those temperature heat will change the physical form of methanol first. and the graph also have been attached of between boiling point and melting point as given in question  .

99.25 grams = .09925 Kg of fluorine gas is needed.

A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Balanced chemical reaction: P₄ (s) + 6F₂ (g) → 4PF₃ (g).

m(PF₃) = 120.0 g; mass of phosphorus trifluoride.

n(PF₃) = m(PF₃) ÷ M(PF₃).

n(PF₃) = 120 g ÷ 88 g/mol.

n(PF₃) = 1.36 mol.

From chemical reaction: n(PF₃) : n(F₂) = 4 : 6 (2 : 3).

n(F₂) = 1.36 mol · 3 / 2.

n(F₂) = 2.04 mol; amount of substance.

m(F₂) = n(F₂) · M(F₂).

m(F₂) = 2.04 mol · 38 g/mol.

m(F₂) = 77.52 g ÷ 0.781.

Answer:

There are many equations for oxidation and reduction, but the most relevant ones are the equations for the half-reactions. In general, the equation for oxidation is:

Oxidation: Reducing Agent + O2 → Oxidizing Agent

And the equation for reduction is:

Reduction: Oxidizing Agent + e- → Reducing Agent

These equations show the transfer of electrons that occurs during oxidation and reduction.

Explanation:

4) 0.05 L of the stock solution must be taken.

5) The osmotic pressure would be 12.23 atm

4) Using the dilution equation: m1v1=m2v2

   m1 = 1M, m2 = 0.1M, v2 = 0.5L

      v1 = m2v2/m1 = 0.1 x 0.5/1 = 0.05 L

5) Using the formula: osmotic pressure = icRT

 Since sucrose does not ionize in water,  i = 1

  C = 0.5

  R = 0.0821

  T = 298

  Osmotic pressure = 1 x 0.5 x 0.0821 x 298 = 12.23 atm
