Ammonium phosphate NH43PO4 is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid H3PO4 with ammonia NH3. What mass of ammonium phosphate is produced by the reaction of 2.5g of ammonia
Answers
Answer:
7.3 g (NH₄)₃PO₄
Explanation:
The balanced equation for the reaction is:
H₃PO₄ + 3 NH₃ ----> (NH₄)₃PO₄
To find the mass of ammonium phosphate ((NH₄)₃PO₄) produced, you need to (1) convert grams NH₃ to moles NH₃ (via the molar mass from the periodic table), then (2) convert moles NH₃ to moles (NH₄)₃PO₄ (via mole-to-mole ratio from balanced equation), and then (3) convert moles (NH₄)₃PO₄ to grams (NH₄)₃PO₄ (via molar mass from periodic table). Make sure to arrange the ratios/conversions in a way that allows for the cancellation of units. The final answer should have 2 sig figs because the given value (2.5 grams) has 2 sig figs.
Molar Mass (NH₃): 14.01 g/mol + 3(1.008 g/mol)
Molar Mass (NH₃): 17.034 g/mol
Molar Mass ((NH₄)₃PO₄):
3(14.01 g/mol) + 12(1.008 g/mol) + 30.97 g/mol + 4(16.00 g/mol)
Molar Mass ((NH₄)₃PO₄): 149.096 g/mol
2.5 g NH₃ 1 mole NH₃ 1 mole (NH₄)₃PO₄ 149.096 g
--------------- x -------------------- x --------------------------- x --------------------------
17.034 g 3 moles NH₃ 1 mole (NH₄)₃PO₄
= 7.3 g (NH₄)₃PO₄

select the weakest reducing agent from the list of answer options. all species without a phase listed are aqueous. g ni(s) pb2 sn(s) al(s) cr2 zn(s)
Answers
The weakest reducing agent from the given list of answer options is Pb2+.
A reducing agent is a substance that donates electrons, thus causing the reduction of another species. In other words, reducing agents are oxidized when they reduce another substance.
The stronger the reducing agent, the more readily it donates electrons, and the more likely it is to cause the reduction of another species. The weaker the reducing agent, the less readily it donates electrons, and the less likely it is to cause the reduction of another species.
To determine the weakest reducing agent:
Pb2+: This species can act as a reducing agent, but it is not very strong. It has a standard reduction potential of -0.13 V.
This means that it is only a weak reducing agent.
Zn(s): This is a strong reducing agent, with a standard reduction potential of -0.76 V. It can readily donate electrons, and is more likely to cause the reduction of another species than Pb2+.Cr2+: This is also a strong reducing agent, with a standard reduction potential of -0.91 V. It can readily donate electrons, and is more likely to cause the reduction of another species than Pb2+.Al(s): This is an even stronger reducing agent, with a standard reduction potential of -1.66 V. It can readily donate electrons, and is much more likely to cause the reduction of another species than Pb2+.Sn(s): This is another strong reducing agent, with a standard reduction potential of -0.14 V. It can readily donate electrons, and is more likely to cause the reduction of another species than Pb2+.Ni(s): This is the strongest reducing agent on the list, with a standard reduction potential of -0.25 V. It can readily donate electrons, and is the most likely to cause the reduction of another species.However, it is not one of the answer options, so we can ignore it.
From this analysis, we can conclude that Pb2+ is the weakest reducing agent from the given list of answer options.

Be sure your answer has the correct number of significant digits.
Need help! Thank you, looked at other examples and I am getting them all wrong.
Answers
Molar concentration of nitrate anions in solution of 0.317g of barium nitrate is dissolved in 150. mL of a 16.0mM aqueous solution of sodium chromate is 0.0032
Since the nitrate ion is NO₃⁻ and barium comes from group 2, it forms the ion Ba²⁺, so the formula for barium nitrate is:
Ba(NO₃)₂. The molar mass is:
137 g/mol, N = 14 g/mol, O = 16 g/mol, so the molar mass of barium nitrate is
137 + 2x(14 + 3x16) = 199 g/mole
The number of moles is the mass divided by the molar mass, so:
n = 0.317/199 = 0.0016 mol Ba(NO₃)₂.
One mole of salt contains 2 moles of NO3-, so the number of moles of nitrate is 0.0032 moles. and the nitrate formed is completely water soluble. Therefore, the number of moles of nitrate remains is 0.0032 moles.
Molarity is the number of moles divided by the volume (0.15 L).
[NO₃⁻] = 0.0032/0.15 = 0.0032
Therefore, molar concentration of nitrate anions in solution of 0.317g of barium nitrate is dissolved in 150. mL of a 16.0mM aqueous solution of sodium chromate is 0.0032

what are the factors affecting gravity?
Answers
Gravity, as a fundamental force of nature, is influenced by several factors. The following are some of the key factors affecting gravity:
Mass: The most significant factor affecting gravity is the mass of the objects involved. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses. Greater mass leads to a stronger gravitational force.Distance: The distance between two objects also plays a crucial role in the strength of gravity. According to the inverse square law, the gravitational force decreases as the distance between objects increases. As objects move farther apart, the gravitational attraction between them weakens.Gravitational Constant: The gravitational constant, denoted by G, is a fundamental constant in physics that determines the strength of the gravitational force. It is a universal constant and does not change, affecting the overall magnitude of gravity.Shape and Distribution of Mass: The distribution of mass within an object can influence the gravitational field it generates. Objects with a more compact and concentrated mass distribution will have a stronger gravitational pull compared to those with a more spread-out mass distribution.External Influences: Gravity can be influenced by external factors such as nearby celestial bodies or the presence of other forces. For example, the gravitational interaction between the Earth and the Moon affects tides on Earth's surface.How does volcanic activity affect climate?

Cómo se denomina el calor que ponen en juego los sistemas materiales cuando cambian su temperatura? Seleccione una: a. Calor cinético b. Calor sensible c. Calor inhumano d. Calor latente
Answers
Answer:
La respuesta correcta es: b. Calor sensible
Explanation:
Al absorber calor, un sistema puede: aumentar su temperatura o cambiar de fase (es decir, pasar de un estado de agregación a otro). Los cambios de fase se producen a temperatura constante, por lo que el calor involucrado se denomina calor latente. Por ejemplo, cuando el agua líquida pasa a vapor por calentamiento a la temperatura de ebullición, esta temperatura se mantiene constante hasta que toda la masa de agua pasa al estado vapor. En cambio, cuando el sistema absorbe calor cambiando su temperatura pero permaneciendo en el mismo estado de agregación (por ejemplo, cuando calentamos agua líquida por debajo de la temperatura de ebullición), el calor involucrado se denomina calor sensible.

When choosing a solvent for recrystallization, it is important that the solvent does not react with the solute.Yes / No
Answers
it is important to choose a solvent for recrystallization that does not react with the solute. The solvent used for recrystallization should dissolve the solute at high temperatures and then allow it to recrystallize when the temperature decreases, without any chemical reaction between the solvent and the solute.
If the solvent reacts with the solute, it can alter the chemical properties of the solute, leading to the formation of unwanted impurities. Choosing the right solvent for recrystallization is critical because the solubility of the solute depends on the solvent used. The solvent should have a high solubility for the solute at high temperatures and a low solubility at room temperature.
The solubility of the solute in the solvent should also be selective, meaning that other impurities should not dissolve in the solvent. Another important consideration when choosing a solvent for recrystallization is the boiling point of the solvent. The solvent should have a boiling point that is lower than the melting point of the solute to facilitate recrystallization. The solvent should also be non-toxic, non-flammable, and easy to remove from the crystals after recrystallization.
Overall, choosing the right solvent for recrystallization is critical to obtain pure crystals and avoid the formation of impurities. It is essential to consider the chemical properties of both the solvent and the solute to ensure that there is no reaction between them and that the crystals obtained are of high purity.
