238 cm = 0.002 38 km

<em>Step 1</em>. Convert <em>centimetres to metres</em>

238 cm × (1 m/100 cm) = 2.38 m

<em>Step 2</em>. Convert <em>metres to kilometres</em>

2.38 m × (1 km/1000 m) = 0.002 38 m

Why do people want different kinds of light bulbs?
ololo11 [35]

Answer:

LED bulbs fit standard light sockets and are the most energy-efficient option. LEDs have lower wattage than incandescent bulbs but emit the same light output. This allows them to produce the same amount of light but use less energy. LEDs can last over 20 years and don't contain mercury

What types of energy can be moved through conductors
Luden [163]
<span>The two types of energy that can be moved through conductors are electrical energy and thermal energy. Conductors are materials that allow electrons to flow freely or transfers heat more easily than other substances. Heat is transfered in conductors when fast moving particles (contains more heat) crash into slow moving particles. conductors allow electrons to flow freely from one object to another in contact. Metals are usually excelent conductors of heat and electricity. </span>

A solution contains 1 LaTeX: \times\:×10−4 M OH– ions. Calculate the solution pH value, and determine if the solution is acidic,
oksano4ka [1.4K]

<u>Answer:</u> The pH value of the solution is 10 and the solution is basic in nature.

<u>Explanation:</u>

To calculate the pH of the solution, we need to determine pOH of the solution. To calculate pOH of the solution, we use the equation:

pOH=-\log[OH^-]

We are given:

[OH^-]=1\times 10^{-4}M

Putting values in above equation, we get:

pOH=-\log(1\times 10^{-4})\\\\pOH=4

To calculate pH of the solution, we use the equation:

pH+pOH=14\\pH=14-4=10

There are three types of solution: acidic, basic and neutral

To determine the type of solution, we look at the pH values.

  • The pH range of acidic solution is 0 to 6.9
  • The pH range of basic solution is 7.1 to 14
  • The pH of neutral solution is 7.

As, the pH of the solution is 10 and is lying in the range of basic solution, so the solution is basic in nature.
