calculate the molar mass of hydrogen phosphate

Answer:

My name is Andreas Vesalius and I'm a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De Humani Corporis Fabrica Libri Septem. I am often referred to as the founder of modern human anatomy. I was born in Brussels, December 31, 1514 which was then part of the Habsburg Netherlands. I was a Flemish doctor who was notable for my contribution to the science of anatomy of the human body. I was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs.

Answer:

94.2 g/mol

Explanation:

Ideal Gases Law can useful to solve this

P . V = n . R . T

We need to make some conversions

740 Torr . 1 atm/ 760 Torr = 0.974 atm

100°C + 273 = 373K

Let's replace the values

0.974 atm . 1 L = n . 0.082 L.atm/ mol.K . 373K

n will determine the number of moles

(0.974 atm . 1 L) / (0.082 L.atm/ mol.K . 373K)

n = 0.032 moles

This amount is the weigh for 3 g of gas. How many grams does 1 mol weighs?

Molecular weight → g/mol → 3 g/0.032 moles = 94.2 g/mol

Answer:

Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice. The energy remains electrical but then changes to kinetic when Enough energy is released.

Explanation:

Answer:

Explanation:

The overabundance of electrical energy acquired by water during the ice framing process is taken out as likely energy to keep up with the law of energy conservation. The electrical energy given to the ice generator pivots the engine inside the blower (compressor). The coolant available inside the blower is compressed and this pressure is accomplished alongside the creation of heat energy. The heat energy is delivered into the external encompassing air of the ice generator. This prompts a drop in the temperature of the coolant.

This coolant courses inside the ice generator and soaks heat energy (heat stream from the heater to the colder area) from the water as it gets once again to the blower, Thus prompting cooling of water and development of ice.

Creativity is a phenomenon whereby something somehow new and somehow valuable is formed. The created item may be intangible (such as an idea, a scientific theory, a musical composition, or a joke) or a physical object (such as an invention, a printed literary work, or a painting).

Scholarly interest in creativity is found in a number of disciplines, primarily psychology, business studies, and cognitive science, but also education, the humanities, technology, engineering, philosophy (particularly philosophy of science), theology, sociology, linguistics, the arts, economics, and mathematics, covering the relations between creativity and general intelligence, personality type, mental and neural processes, mental health, or artificial intelligence; the potential for fostering creativity through education and training; the fostering of creativity for national economic benefit, and the application of creative resources to improve the effectiveness of teaching and learning.

Answer:

The answer would have to be public education on the importance of washing hands.

Explanation: Washing hands is always one of the best ways to prevent a contagious disease.

Answer:

- The chemical reaction is not balanced. There is two oxygens on the reactant's side while there's only one oxygen on the products side.

- I would not say it's following the law of conservation of mass as it's not a balanced equation.

- To balance this equation, you would need to add the coefficient of '2' to Magnesium (Mg) on the reactants side, and add the coefficient of '2' to the products side.  This would make it so that there's 2 Mg's and 2 O's on both the reactant's side and products side.

Answer:

Explanation:

A hydrogen atom has an atomic number of 1.

So it's proton number will always be 1.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also 1.

A neutral hydrogen atom has an atomic mass of ≈

1.00794 amu ≈ 1 amu.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

1 − 1 = 0

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

1 proton

1 electron

0 neutrons

Answer:C

Explanation:

Got it right in usatestprep

The physical evidence that indicates that there has been a chemical reaction is that the beaker changes temperature and the correct option is option C.

Neutralization is a chemical reaction in which acid and base react to form salt and water. Hydrogen (H⁺) ions and hydroxide (OH⁻ ions) react with each other to form water.

The strong acid and strong base neutralization have a pH value of 7.

The beaker gets warm which indicates that the reaction between acid and base is an exothermic reaction releasing heat energy into the surroundings.

Therefore, The physical evidence that indicates that there has been a chemical reaction is that the beaker changes temperature and the correct option is option C.

Natural Gas is a fossil energy source that formed deep beneath the Earth's surface. It is used in power plants to generate electricity by burning natural gas as their fuel.

Explanation: I hope this helped :)

Answer:

A molecule of natural gas is made up of carbon and hydrogen. When the hydrogen is segregated from the carbon and filled into a fuel cell, it fuses with oxygen to produce water, electricity, and heat. The carbon is released as carbon dioxide in smaller quantities than from gas turbines.

Answer:

0.109M

Explanation:

Find molarity of the solution:

Molarity is defined as the ratio between the moles of the solute (Lithium Chloride in this case) per liter of solution. To solve this question we have to find the moles of LiCl and its volume as follows:

Moles LiCl -Molar mass: 42.394g/mol-

2.3g * (1mol / 42.394g) = 0.0543 moles

Volume in liters:

500cm³ * (1L / 1000cm³) = 0.500L

Molarity:

0.0543 moles / 0.500L =

0.109M

Answer: A solid silver, Ag, conducts electricity because it contains ions or electrons while solid silver chloride, AgCl, does not conduct electricity because AgCl does not dissociate to give ions or electrons.

Explanation:

Solid silver (Ag) is considered to be a good conductor of electricity because there are more number of free electrons or movable atoms are present in it.

As electricity is the flow of ions or electrons. So, more is the number of ions or electrons present in a substance more will be its conductivity.

Whereas solid silver chloride is a precipitate that is insoluble in water and therefore, it will not give ions or electrons.

As a result, silver chloride is not able to conduct electricity.

Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Explanation:

Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense. ... Seafloor spreading proves that the ocean itself is a site of tectonic activity.

Answer:

1.14 M

Explanation:

Step 1: Calculate the moles corresponding to 317 g of calcium chloride (solute)

The molar mass of calcium chloride is 110.98 g/mol.

317 g CaCl₂ × 1 mol CaCl₂/110.98 g CaCl₂ = 2.86 mol CaCl₂

Step 2: Calculate the molarity of the solution

Molarity is equal to the moles of solute divided by the liters of solution.

M = moles of solute / liters of solution

M = 2.86 mol / 2.50 L = 1.14 mol/L = 1.14 M

Explanation:

¡Hola!

En este caso, dado que es posible para nosotros relacionar moles con gramos por medio de la masa molar y moléculas con moles por medio del número de Avogadro, resulta factible para nosotros primero calcular las moles en las moléculas dadas y de esta manera luego calcular los gramos, teniendo en cuenta una masa molar de 60.05 g/mol ya que el vinagre se puede estudiar como ácido acético (CH3COOH):

[tex]2x10^{23}molec*\frac{1mol}{6.022x10^{23}molec}=33.2mol[/tex]

Seguidamente, calculamos los gramos:

Answer:

a. absorbs energy as heat and has positive enthalpy of solution.

Explanation:

A reaction can either be exothermic or endothermic. An endothermic reaction, as the dissolution described in the question, is that which absorbs heat energy from the surroundings in order to start the reaction.

Because an endothermic reaction makes heat lost from the surroundings, the enthalpy (∆H) of the solution will be positive (+). ∆H is got by finding the difference between the enthalpy of the reactants and products and since the enthalpy of a product in endothermic reaction is more, the enthalpy change (∆T) will be positive.
