Answer:
1.95*10²² molecules are in 5.50 grams of AgNO₃
Explanation:
Being the molar mass of the elements:
- Ag: 107.87 g/mole
- N: 14 g/mole
- O: 16 g/mole
then the molar mass of the compound is:
AgNO₃: 107.87 g/mole + 14 g/mole + 3*16 g/mole= 169.87 g/mole
Then you can apply the following rule of three: if 169.87 grams of the compound are present in 1 mole, 5.50 grams will be present in how many moles?
moles= 0.0324
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.
You can apply the following rule of three: if by definition of Avogadro's Number 1 mole of the substance contains 6.023 * 10²³ molecules, 0.0324 moles how many molecules will it have?
molecules=1.95*10²²
<u><em>1.95*10²² molecules are in 5.50 grams of AgNO₃</em></u>
Answer:
point 2 and 4
Explanation:
because at those point temperature is constant
Answer:
B. Write the chemical equation using formulas and symbols.
D. Count the atoms in each substance in the reactants and products,
Explanation:
When balancing chemical equation, it implies that the law of conservation of matter be strictly adhered to.
By so doing, the number of atoms on both sides of the reaction must be the same. Number of atoms in the products and reactants must have the same value.
- It is always a good approach to first write the chemical equation of the reaction.
- This will give an overview of the reacting species and the products being formed.
- Then, go on to count the number atoms in the reactants and product sides of the expression.
- Then balance it using any of the method of balancing chemical equations.
The correct answer is A. The equation is not balanced because the number of atoms of each element on the left is not equal to their numbers on the right.
There is 1 chlorine atom on the left. However, there are 5 chlorine atoms on the right.
There is 1 hydrogen atom on the left, but 2 hydrogen atoms on the right.
There are 4 oxygen atoms on the left, but 1 oxygen atom on the right
There is 1 manganese atom on the left and right side of the equation.
There is also 1 potassium atom on the left and right side.
The equation is clearly not balanced.
The hybridization of the central atom in SCl₂ is sp³.
<h3>What is Lewis Structure ? </h3>
Lewis structure is also known as Lewis dot structure which simply represent the valence electron of an atom.
<h3>What is Hybridization ? </h3>
Hybridization is defined as the mixing of two atomic orbitals belongs to same atom but having entirely different shapes , energies which produces a new hybridized orbitals.
Now first write the electronic configuration of central atom.
The central atom in SCl₂ is S (Sulphur).
Electronic configuration of S: [Ne] 3s² 3p⁴
One 3s and three 3p undergo hybridization to form sp³ orbitals. Here each atom forms bond with one sp³ hybrid orbital.
Thus from the above conclusion we can say that The hybridization of the central atom in SCl₂ is sp³.
