what is the concentration of an NaOH solution that requires 50 mL of a 1.25 M H2SO4 solution to neutralize 78.0 ml of NaOH​
Dimas [21]

Answer:

  • The answer is the concentration of an NaOH = 1.6 M

Explanation:

The most common way to solve this kind of problem is to use the formula  

  • C₁ * V₁ = C₂ * V₂

In your problem,

For NaOH

C₁ =??     v₁= 78.0 mL = 0.078 L

For H₂SO₄

C₁ =1.25 M     v₁= 50.0 mL = 0.05 L

but you must note that for the reaction of NaOH with H₂SO₄

2 mol of NaOH raect with 1 mol H₂SO₄

So, by applying in above formula

  • C₁ * V₁ = 2 * C₂ * V₂
  • (C₁ * 0.078 L) = (2*  1.25 M * 0.05 L)
  • C₁ = (2*  1.25 M * 0.05 L) / (0.078 L) = 1.6 M  

<u>So, the answer is the concentration of an NaOH = 1.6 M</u>

Describe how wind, water, ice and gravity move soil through erosion below.<br> PLEASE ANSWER!!!! :D
8_murik_8 [283]

Answer:

Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of rock and soil are suspended in the fluid (air or water) and being transported from one place to another. This transported material is called sediment.

A substance with which bond type would have a high melting point?
DaniilM [7]

Answer:

The answer to your question is A. Ionic

Explanation:

There are 3 kinds of bonds in chemistry

a) Ionic bonds are the bonds between a metal and a nonmetal. Metals lost their electrons and nonmetals gain them. These bonds are the strongest so the melting and boiling points are the highest of all.

b) Covalent bonds are bonds between two nonmetals. The elements share electrons so these bonds are not as stronger as Ionic bonds, the melting and boiling points are high.

c) Metallic bonds are among metals and have high melting and boiling points.
