4.60 mL of 0.1852 M HNO3 is titrated to the phenolphthalein indicator endpoint with 27.35 mL of a KOH solution. What is the mola
Kamila [148]

Answer:

M_{base}=0.0311M

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve for the molarity of the KOH solution by knowing this base react in a 1:1 mole ratio with nitric acid, HNO3; thus, we can write the following equation, as their moles are the same at the endpoint:

n_{acid}=n_{base}

Which in terms of molarities and volumes is:

M_{acid}V_{acid}=M_{base}V_{base}

Thus, we solve for the molarity of the base (KOH) to obtain:

M_{base}=\frac{M_{acid}V_{acid}}{V_{base}} \\\\M_{base}=\frac{4.60mL*0.1852M}{27.35mL}\\\\M_{base}=0.0311M

Regards!

Define the term "transfer energy" in your own words
Soloha48 [4]

Answer:

Energy is the ability to do work, or in more simple terms: energy makes things happen. You use energy to ride your bike, play video games, bake cookies, and drive to school. Energy is exciting! Energy can be transferred from one object to another, and energy can be transferred into different forms, such as light, sound, and heat.

An element has two isotopes, A and B, with mass numbers of 32.0 and 33.0 respectively. The relative atomic mass is 32.3. The per
vlada-n [284]

Answer:

d) A - 70% B - 30%

Explanation:

If x is the abundance of A, and 1−x is the abundance of B, then:

x (32.0) + (1−x) (33.0) = 32.3

32x + 33 − 33x = 32.3

33 − x = 32.3

x = 0.7

The abundance of A is 70%, and the abundance of B is 30%.

Explain why solid sodium chloride does not conduct electricity
aleksandr82 [10.1K]

Answer:

It does not contain free mobile ions

Explanation:

Solid sodium chloride does not conduct electricity because it does not contain free mobile ions.

  • Although sodium chloride is an ionic compound, in solid state, there is absence of free mobile ions.
  • In aqueous solutions or in molten form, ionic compounds can conduct an electric current using free mobile ions as carriers.
  • Therefore, they are electrolytes.

In solid state ions are arranged into crystal lattice and will not conduct a current of electricity.
