serg [7]3 years ago
5 0

<u>Answer :</u>

Part 13:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3

Part 14:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3

Part 15:

The balanced chemical reaction will be:

Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3

<u>Explanation :</u>

Balanced chemical reaction : It is defined as the reaction in which an individual element of an atom present on reactant side must be equal to product side.

Part 13:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3

Part 14:

The balanced chemical reaction will be:

Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3

Part 15:

The balanced chemical reaction will be:

Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3

According to the chart of specific heats, which material requires the most heat to raise its temperature from 10°C to 30°C?
myrzilka [38]

The material which requires the most heat to raise its temperature from 10°C to 30°C is oil.

<h3>What is the formula to calculate absorbed heat?</h3>

The formula which we used to calculate the amount of involved heat in relation with specific heat is:

Q = mcΔT, where

  • Q = absorbed heat
  • m = mass
  • c = specific heat
  • ΔT = change in temperature

Among the given materials, specific heat of oil is highest than other materials so will require maximum absorbed heat.

Hence, oil requires the most heat.

Explain why it is necessary to balance chemical equations in terms of maintaining equilibrium. How can you tell when a chemical
LUCKY_DIMON [66]

Answer:

See explanation.

Explanation:

Hello,

In this case, we say that chemical reactions are governed by the law of conservation of mass, which states that matter cannot be neither created nor destroyed by transformed, for that reason, we need to balance chemical reactions in order to ensure all the atoms to be in the same quantity at both reactants and products.

Moreover, equilibrium is defined as such condition at which the concentration of both reactants and products stop changing over the time so they become constant as well as their null reaction rate.

A widely acknowledged reaction is the HABER one which consists on the synthesis of ammonia by using elemental nitrogen and hydrogen:

N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)

In such reaction, we have two nitrogens at both reatants and products and six hydrogens at at both reatants and products for us to obey the law of conservation of mass. Furthermore, as the time goes by, nitrogen reacts with hydrogen, nonetheless, they do not react indefinitely, they have a limit that is equilibrium, so their moles stop being consumed and remain unchanged as well as the produced moles of ammonia.

Best regards.

At which temperature and pressure will a sample of neon gas behave most like an ideal gas?
Andreas93 [3]

Answer:

At STP, 760mmHg or 1 atm and OK or 273 degrees celcius

Explanation:

The standard temperature and pressure is the temperature and pressure at which we have the molecules of a gas behaving as an ideal gas. At this temperature and pressure, it is expected that the gas exhibits some properties that make it behave like an ideal gas.

This temperature and pressure conform some certain properties on a gas molecule which make us say it is behaving like an ideal gas. Ordinarily at other temperatures and pressures, these properties are not obtainable

Take for instance, one mole of a gas at stp occupies a volume of 22.4L. This particular volume is not obtainable at other temperatures and pressures but at this particular temperature and pressure. One mole of a gas will occupy this said volume no matter its molar mass and constituent elements. This is because at this temperature and pressure, the gas is expected to behave like an ideal gas and thus exhibit the characteristics which are expected of an ideal gas
