The the balanced equations to: solutions of lithium sulfate and potassium phosphate are mixed together to make lithium phosphate

and potassium sulfate
Chemistry
1 answer:
nevsk [136]2 years ago
8 0

Answer:

3Li_2SO_4+2K_3PO_4\rightarrow 2Li_3PO_4+3K_2SO_4

Explanation:

Hello!

In this case, when lithium sulfate and potassium phosphate solutions are mixed to yield lithium phosphate and potassium sulfate, the following chemical equation comes up:

Li_2SO_4+K_3PO_4\rightarrow Li_3PO_4+K_2SO_4

However, as atoms are not balanced we apply the inspection method to obtain:

3Li_2SO_4+2K_3PO_4\rightarrow 2Li_3PO_4+3K_2SO_4

Best regards!

If an atom has an electron in the n = 4 state with ml = 2, what are the possible values of l?
Pavel [41]

Answer:

The possible values of l are 2 and 3

Explanation:

Each electrons have four quantum numbers:

  • n: the principal quantum number, which value matches with the energy level of the electron.
  • l: the secondary quantum number, which value can be from 0 to n-1
  • m: the magnetic number, which value can be from -l to l
  • sp: the spin number which value can be -1/2 or +1/2

In this case, n=4 so the values of l are:

l=0, 1, 2, 3

Now, if:

  • l=0 the value of m is m=0
  • l=1 the values of m are m= -1, 0, 1
  • l=2 the values of m are m= -2, -1, 0, 1, 2
  • l=3 the values of m are m= -3, -2, -1, 0, 1, 2, 3

Being all that said, l can be either  equal to 2 or 3

What is the formula (with cation and anion charges) for copper (II) hydroxide? ​
Thepotemich [5.8K]

Answer:

Cu²⁺(OH)⁻₂

Explanation:

Step 1: Find the symbols for the substances

For copper, see your periodic table. Copper is "Cu".

For hydroxide, see your polyatomic ions chart. Hydroxide is "OH".

Step 2: Find the charges for each element.

Copper (II)'s charge is 2, which is the roman numerals in the brackets.

Hydroxide's charge is -1.

Charges are written as superscripts. You do not need to write "1".

In formulas, write the positively charged atom first.

Cu²⁺(OH)⁻   Put brackets around hydroxide because it has 2 elements.

Step 3: Write the number of atoms.

The number of atoms that an element has is the same as its partner's charge.

The charge of copper is 2, so hydroxide has 2 atoms.

The charge of hydroxide is 1, so copper has 1 atom.

Cu²⁺₁(OH)⁻₂

You do not need to write the "1" for atoms.

Cu²⁺(OH)⁻₂

What effect does reusing or recycling municipal waste have on environmental resources? Group of answer choices increased use of
Effectus [21]

Answer:

preservation of raw materials

Explanation:

Reusing and recycling is the process by which the used products are used again or recycled in different form to use it again. Excessive use of the raw materials can lead to their extinction. Recycling the materials helps in decreasing the pollution in the environment. It also helps in reduction in the emission of the harmful gases. When municipal wastes are reused or recycled, the raw materials are preserved. These are the process involved in sustainable use of resources.
