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.

Answers

Answer:

I-131- To treat goitre

U- 238- To produce electricity

(ii) (ii) and (iii)

Explanation:

Radioisotopes have various applications in science. These applications may be positive or negative.

I-131- is used to treat goitre. This is a very important medical application of this isotope of iodine.

U-238 is ordinarily non-fissile but can be transformed to Pu-239 and used as a nuclear fuel for electricity generation.

how many atoms are there in 8.08 moles of carbon dioxide

Answers

Answer:

145.97×10²³ atoms

Explanation:

Given data:

Number of moles of CO₂ = 8.08 mol

Number of atoms of CO₂ = ?

Solution:

1 mole of CO₂ contain 1 mole C atom.

8.08 mole contain 8.08× 1 = 8.08 mole of C atom.

1 mole of CO₂ contain 2 moles of O atom.

8.08mole contain 8.08×2 = 16.16 mole of O atom.

Total number of moles of atoms = 8.08 mole + 16.16 mole

Total number of moles of atoms = 24.24 mol

Number of atoms of CO₂:

1 mole of any substance contain 6.022×10²³ atoms.

24.24 mol ×6.022×10²³ atoms / 1 mol

145.97×10²³ atoms

Answer:

Explanation:

The equator is also called the doldrum or the region of calms here the winds are moving slowly and consist of warmth and moisture. Thus developing a low-pressure system.  Due to which the cool and dense winds that blow from the poles reach the equator and the warm winds move towards the poles balancing the temperatures in both the regions.  As these regions don't receive most of the sunlight they have high-pressure cells.

Consider the reaction
H,01) +energy > H2(g) +%02(g)
Which of the following phrases best describes this reaction?
A Endothermic, absorbing energy
B) Endothermic, releasing energy
C) Exothermic, absorbing energy
D) Exothermic, releasing energy

Answers

The following phrases best describe this reaction : A Endothermic, absorbing energy

Further explanation

Delta H reaction (ΔH) is the amount of heat change between the system and its environment  

(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)  

∆H positive (endothermic): energy (heat) is absorbed from the environment to the system

∆H negative (exothermic): energy (heat) released from the system to the environment

Reaction

H₂O(g) + energy ⇒ H₂(g) + 1/2O₂(g)

In this reaction, it is shown that to break the bonds on the H₂O molecule to form H₂ and O₂ molecules will require energy (breaking the bonds requires energy)

This energy is usually called ∆H dissociation⁰

A mixture contains 21.7 g NaCI, 3.74 g KCI, and 9.76 g Lici. What is the mole fraction of NaCl in this mixture?

Molar mass
NaCl: 58.44g/mol
KCl: 74.55g/mol
LiCl: 42.39g/mol​

Answers

Answer:Mole Fraction of NaCl=0.5697

Explanation:

No OF Moles of NaCl=  Mass / Molar mass

=21.7 g/58.44g/mol

=0.371moles

No OF Moles of KCl=  Mass / Molar mass

=3.74g/74.55g/mol

=0.0502moles

No OF Moles of LiCl=  Mass / Molar mass

=9.76 g/42.39g/mol

=0.230moles

Mole Fraction of NaCL = Moles of NaCL/ Total number of moles of the mixture

=0.371/( 0.371+ 0.0502+0.230)

0.371/0.6512

=0.5697

Answer:

Mole fraction: 0.570

Explanation:

Mole fraction is defined as the ratio of moles of a compound in a mixture over the total moles of the mixture. To solve this problem, we need to find moles of the 3 salts:

Moles NaCl -Molar mass: 58.44g/mol-:

21.7g NaCl * (1mol / 58.44g) = 0.3713 moles

Moles KCl -Molar mass: 74.55g/mol-:

3.74g KCl * (1mol / 74.55g) = 0.0502 moles

Moles LiCl -Molar mass: 42.394g/mol-:

9.76g LiCl * (1mol / 42.394g) = 0.2302 moles

Mole fraction NaCl:

0.3713mol / (0.3713mol + 0.0502mol + 0.2302mol) =

0.570
