suppose of ammonium sulfate is dissolved in of a aqueous solution of sodium chromate. calculate the final molarity of ammonium cation in the solution. you can assume the volume of the solution doesn't change when the ammonium sulfate is dissolved in it. round your answer to significant digits.
The final molarity of the ammonium cation in the solution is 0.066M.
Firstly, we need to calculate the number of moles of ammonium sulfate:
No of moles = mass(g)/molar mass
No of moles = 2.57/132.14
No of moles = 0.0195 mol
When ammonium sulfate dissolves in sodium chromate, the following reaction will take place:
(NH₄)₂SO₄ + Na₂CrO₄ ------> (NH₄)₂CrO₄ + Na₂SO₄
No of Moles of sodium chromate = molarity x volume
= 66 x 0.200
No of moles of Sodium Chromate = 0.0132 mol
According to the reaction, 1 mol of sodium chromate produces 1 mol of ammonium chromate.
In this reaction, the sodium chromate amount is less than ammonium sulfate.
It can be concluded that Sodium chromate is a limiting reagent.
Therefore 0.0134 mol of ammonium cation is present in the resulting solution.
Molarity of ammonium cation = 0.0134 mol / 0.2 L
Molarity = 0.066 M
Therefore, 0.066M is the Molarity of the ammonium cation.

Peripheral chemoreceptors are specialized cells in contact with arterial blood that respond directly to changes in blood ________.A) pHB) PO2C) PCO2D) PCO2 and PO2E) PO2, pH, and PCO2
Specialized cells called peripheral chemoreceptors in contact with arterial blood react immediately to variations in blood PO2.
Carotid and aortic bodies, which are peripheral chemoreceptors, sense changes in arterial blood oxygen levels and set off reflexes that are crucial for preserving homeostasis in hypoxemia. The carotid (and aortic) bodies, which act as peripheral chemoreceptors, recognise arterial hypoxia and promote breathing. They give the brain stem a constant excitatory input at normal arterial PO2 (PaO2) values (6), and in hypoxia, they react dramatically as PaO2 drops below 70 Torr. With some help from [H+], peripheral chemoreceptors are particularly sensitive to changes in PaO2. The peripheral chemoreceptor hypoxic response predominates in situations where the receptors disagree, such as hypoxic hypocapnia, causing the respiratory drive to increase oxygenation despite additional reductions in CO2.

Lithium oxide is used to absorb carbon dioxide:
Li2O(s) + CO2(g) → Li2CO3(s)
What volume of CO2 can 6.77 g of Li2O absorb if the CO2 pressure is 3.5 × 10−4 atm and the temperature is 295 K?
Answer:160 L of CO₂.
Explanation: Give me brainly please.
The volume of CO₂ absorbed is 0.371 L (or 371 mL) at 3.5 × 10⁻⁴ atm and 295 K.
To calculate the volume of CO₂ absorbed by 6.77 g of Li₂O, we need to use the ideal gas law, which states:
PV = nRT
where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature in Kelvin.
First, calculate the number of moles of CO₂:
Molar mass of Li₂O = 2 * (6.94 g/mol) + 15.999 g/mol ≈ 29.88 g/mol
Moles of Li₂O = 6.77 g / 29.88 g/mol ≈ 0.2263 mol
Now, we can use the given pressure and temperature:
P = 3.5 × 10⁻⁴ atm
T = 295 K
Rearrange the ideal gas law to solve for V:
V = nRT / P
V = (0.2263 mol) * (0.08206 L atm/mol K) * (295 K) / (3.5 × 10⁻⁴ atm)
V ≈ 0.371 L
So, the volume of CO₂ that 6.77 g of Li₂O can absorb at 3.5 × 10⁻⁴ atm and 295 K is approximately 0.371 L (or 371 mL).

Correct the volume of 2.90 L of a gas at –12 °C to the volume occupied at 25 °C. Remember to convert between °C and K.
The volume occupied at 25 °C. Remember to convert between °C and K. V2 = 3.311 L is the correct answer.
What is volume?
Volume is a measure of the amount of space occupied by an object, or the amount of matter contained within it. It is measured in units such as cubic metres, cubic centimetres, litres, millilitres, etc. Volume is a three-dimensional concept, meaning that it requires three measurements to be taken in order to accurately measure the amount of space an object occupies. The volume of a solid object can be determined by applying the formula V = l x w x h, where l is the length, w is the width, and h is the height of the object. For a liquid or gas, the volume is calculated by measuring its mass and the density of the substance. Volume can also be used to describe the total amount of space something occupies, such as the volume of a room or the volume of a storage container.
Temperature and Volume equation
Given,
The volume at -12°C = 2.90L
Temperature, T1 = -12°C
= (-12°C + 273)
= 261K
And, Volume at 25°C = ?
(25°C + 273)K
= 298K
Now, by using this equation:-
V1/T1 = V2/T2
V2 = V1 x T2/T1
V2 = 2.90L x 298K/261K
V2 = 3.311L
Hence, The volume at 25°C will be 3.311L

Atoms will combine with each in order to become more chemically stable. Compound are formed between two atoms that hare outer energy levels. The two types of compounds that can be formed between atoms are ionic and covalent. Ionic compounds are formed between two nonmetal ion. Metals will lose electrons to form positive ions and nonmetals will gain electrons to form negative ions. These oppositely charge ions are very attracted to each other and form very strong bonds as a result. lonic compounds are characterized by crystalline structure, Two: or more pairs of electrons. The force of attraction between the nonmetals is relatively weak. Covalent compounds are characterized by i meting and boiling points and can be gases, liquids, or soft solids at room temperature.
The majority of stable atoms share electrons. When two atoms share electrons, they establish a covalent bond. The result of sharing electrons are molecules, which are neutral particles.
Why does an atom's outer energy level reach its maximum when it is full?Due to the fact that all orbitals will be filled, an entire octet is exceedingly stable. A process that increases the stability of the atoms will release energy in the form of heat or light because more stable atoms have less energy.

1. SEP Develop Models
Use the space to draw electron dot structures to model the bonding in calcium oxide (CaO), calcium chloride (CaCl₂), and potassium nitride (K₂N). As you develop your models, consider the following: Use the diagram for NaCl as a guide for your electron dot structures. After the bond is formed, each ion should have a complete outer electron shell, and the overall charge on the compound should be zero.
Answer:
Calcium Oxide must be Ionic, as we have one metal and one non metal involved. the metal is Calcium and the non metal is Oxygen. Meaning Calcium must be the one that transfers (loses) electrons to Oxygen, and Oxygen gains these electrons. It would look something like this:
Because Calcium transfers 2 electrons, it now has 2 more positively charged protons than the total number of electrons, as two electrons are lost. this means Calcium is no longer an atom, as it's positive protons and negative electrons can't cancel and make it neutral, it is now an ion, and a positively charged one at that. Same thing applies for Oxygen, but the opposite. because it has 2 more negative electrons than it's total of positive protons, it is now also an ion, and a negative one at that. The diagrams provided show the charges of the ions.
Potassium Nitrate must also be Ionic, for the same reason as before. the metal is Potassium and the non metal is Nitrogen. However, because Potassium is in Group 1, it only has 1 electron it can transfer to Nitrogen, but Nitrogen needs 2 electrons for a full outer energy level, therefore, we must have two Potassium atoms in this equation. It would look something like this:
Because there are two Potassium ions, each with a +1 charge, this means the overall charge of the Potassium ions is 2+, and this cancels out with the 2- provided by one ion of Nitrogen

The nitrogen cycle refers to the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it moves among terrestrial, atmospheric, and marine ecosystems. It is a repeating cycle of processes during which nitrogen circulates through both living and non-living things: the atmosphere, soil, water, plants, animals, and bacteria. In order to move through the different parts of the cycle, nitrogen must change forms. The conversion of nitrogen can be carried out through both biological and physical processes. The nitrogen converts into NO2 through stationary combustion and into NH4+ through decomposition. Fixation converts nitrogen in the atmosphere into forms that plants produce i.e., NH4+.
