What is the chemical formula for zinc (II) phosphate?

Answers

Answer:

Zn^3(PO4)2

Explanation:

thats the formula

The chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.

Zinc (II) phosphate is an inorganic chemical compound that is made up of zinc cations  and phosphate anions .The chemical formula for zinc (II) phosphate is obtained by combining three zinc cations with two phosphate anions to achieve the neutral charge.

Chemical  formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols  of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form  is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.

Thus, chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.

in which of the following is the symbol for the ion and the number of electrons it contains given correctly? *

Answers

Answer:Number of electrons that are present in an atom is determined by the electronic configuration of that atom.

If an ion is carrying a positive charge, it means that the atom has lost electrons and if an ion is carrying a negative charge, it means that the atom has gained electrons.

For the given options:

Option A: The atomic number of hydrogen atom is 1 and the electronic configuration for  ion will be:  

Thus, this atom does not have any electrons.

Option B: The atomic number of bromine atom is 35 and the electronic configuration for  ion will be:

A neutral atom of beryllium (Be) has an average mass of 9 amu and 4 electrons. How many neutrons does it have?

13
5
9
4

Answers

Answer:

It has 5 neutrons

Explanation:

The fact that it is a neutral atom tells us that the number of electrons and protons is the same:

The problem tells us there are 4 electrons, thus there are 4 protons.

The average mass of an atom is the sum of the number of protons and the number of neutrons:

Mass = # Protons + # Neutrons

With the above information in mind we can calculate the number of neutrons:

9 amu = 4 Protons + # Neutrons# Neurons = 5 Neutrons

How many molecules are in 1200 g of acrylonitrile (C3H3N), a chemical used in the production of plastic
Help

Answers

Answer: [tex]136.2\times 10^{23}[/tex] molecules

Explanation:

According to avogadro's law, 1 mole of every substance contains avogadro's number of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}=\frac{1200g}{53.06g/mol}=22.62moles[/tex]

1 mole of acrylonitrile has = [tex]6.023\times 10^{23}[/tex] molecules

Thus 22.62 moles of  acrylonitrile has = [tex]\frac{6.023\times 10^{23}}{1}\times 22.62=136.2\times 10^{23}[/tex] molecules

Taking into account the definition of Avogadro's number, 1.36×10²⁵ molecules of C₃H₃N are in 1200 g.

Avogadro's Number

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Mass molar

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

The molar mass of a compound (also called Mass or Molecular Weight) is the sum of the molar mass of the elements that form it (whose value is found in the periodic table) multiplied by the number of times they appear in the compound.

This case

In this case, you know the molar mass of the elements is:

C= 12 g/moleN= 14 g/moleH= 1 g/mole

So, the molar mass of the compound C₃H₃N is calculated as:

C₃H₃N= 3× 12 g/mole + 3× 1 g/mole + 14 g/mole

Solving:

C₃H₃N= 53 g/mole

You have 1200 g of C₃H₃N. So, knowing its molar mass, you can calculate the number of moles that contain a mass of 1200 g as:

1200 g×[tex]\frac{1 mole}{53 grams} [/tex]= 22.64 moles

Then you can apply the following rule of three: If by definition of Avogadro's number 1 mole of C₃H₃N contains 6.023×10²³ molecules, 22.64 moles of C₃H₃N contains how many molecules?

amount of molecules of C₃H₃N= (22.64 moles × 6.023×10²³ molecules)÷ 1 mole

amount of molecules of C₃H₃N= 1.36×10²⁵ molecules

Finally, 1.36×10²⁵ molecules of C₃H₃N are in 1200 g.

Determine the molar mass of Ze(NO3)2. (Ze=55.85 N=14.01 O=16.00) *
Help

Answers

Answer:

179.87 g/mol

Explanation:

First you need to determine the number of each elements in the molecule.  This information comes from the molecular formula.  

Ze(NO3)2 tells us that there is 1 Ze atom and 2 NO3 anions per molecule.  each NO3 anion will have 1 nitrogen and 3 oxygens.  Due to that, one molecule of Ze(NO3)2 will have 1 atom of Ze, 2 atoms of nitrogen (N), and 6 atoms of oxygen (O).

Next you need to add all of the individual atom's molar masses to get the over all molar masses.  The molar masses of each element is in the question but it can also be found on the periodic table.

molar mass of Ze(NO3)2 = 55.85g/mol + (14.01g/mol*2) + (16.00g/mol*6)

molar mass of Ze(NO3)2 = 179.87 g/mol

An unknown metal with a mass of 585.6 grams, changes temperature from 46.5°C to 84.5°C when it absorbs 795J of energy. Find specific heat of the unknown metal.

Answers

Answer: So the answer would be um I dont

know the answer right now but message me later on and I will help

Explanation: The equation that relates heat  (q) to specific heat (c_p) , mass (m), and temperature change  (Delta{T}) is shown below.

q=c_p times m times Delta{T}  The heat that is either absorbed or released is measured in joules. The mass is measured in grams. The change in temperature is given by Delta{T}= T_f - T_i , where  T_f is the final temperature and  T_i is the initial temperature. Step 1: List the known quantities and plan the problem .

Known

heat = q = 134 J

mass =  m = 15.0 g

Delta{text{T}} = 62.7^circ text{C} - 24.0^circ text{C} = 38.7^circ text{C}

Unknown

c_p text{of cadmium}= ? text{J}/ text{g}^circ text{C}

The specific heat equation can be rearranged to solve for the specific heat.

Step 2: Solve .

c_p=frac{q}{m times Delta{T}}=frac{134 text{ J}}{15.0 text{ g} times 38.7^circ text{C}}=0.231 text{ J/g}^circ text{C}

Step 3: Think about your result .

The specific heat of cadmium, a metal, is fairly close to the specific heats of other metals. The result has three significant figures.

Since most specific heats are known, they can be used to determine the final temperature attained by a substance when it is either heated or cooled. Suppose that a 60.0 g sample of water at 23.52°C was cooled by the removal of 813 J of heat. The change in temperature can be calculated using the specific heat equation.

Delta{T}=frac{q}{c_p times m}=frac{813 text{ J}}{4.18 text{ J/g}^circ text{C} times 60.0 text{ g}}=3.24^circ text{C}

Since the water was being cooled, the temperature decreases. The final temperature is:

T_f=23.52^circ text{C} - 3.24^circ text{C}=20.28^circ text{C}
