0.000000655 mL in scientific notation

Chemistry
1 answer:
alina1380 [7]3 years ago
3 0

Answer:

<u>The answer is 6.55 * 10⁻⁷</u>

Explanation:

Let's write 0.000000655 mL in scientific notation:

The first step is you have to move the decimal place until you have a number between 1 and 10. If you keep moving the decimal point to the right in 0.000000655 you will get 6.55.

Now, the second step is you count how many places you moved the decimal point. You moved it 7 places to the right to change 0.000000655 to 6.55.

Finally, You need to show that you moved the decimal point 7 places to the right by noting that the number should be multiplied by 10⁻⁷ because a power of ten with a negative exponent, such as 10⁻⁷, means the decimal was moved to the right.

<u>The answer is 6.55 * 10⁻⁷</u>

Calculate the work (kJ) done during a reaction in which the internal volume expands from 20 L to 43 L against an outside pressur
Alenkinab [10]

Answer:

\large \boxed{\text{-10.0 kJ}}

Explanation:

1. Calculate the work

w = - pΔV = -4.3 atm × (43 L - 20 L) = -4.3 × 23 L·atm = -98.9 L·atm

2. Convert litre-atmospheres to joules

w = \text{-98.9 L\cdot$atm } \times \dfrac{\text{101.3 J}}{\text{1 L$\cdot$atm }} = \text{-10000 J} = \textbf{-10.0 kJ}\\\\\text{The work done is $\large \boxed{\textbf{-10.0 kJ}}$}

The negative sign indicates that the work was done against the surroundings.

Romashka [77]

In an electrolytic cell, the electrode that acts as a source of electrons to the solution is called the <u>cathode</u>; the chemical change that occurs at this electrode is called <u>reduction</u>.

<h3>Define Electrolyte:-</h3>

An electrolyte is a material that separates into charged ions when it is in contact with water. Cations are positively charged ions. Anions are ions that are negatively charged. A substance that may conduct an electric current when melted or dissolved in water is known as an electrolyte.

<h3>Electrochemical cell </h3>

There are three main categories of electrochemical cells. the galvanic cell, the concentration cell, and the electrolytic cell. These cells all share the same four fundamental components. These are the elements

  • The electrolyte serves as the conduit for current flow between the anode and the cathode. In an aqueous solution, it normally is homogeneous, but in moist soil, the concentration or kind of dissolved compounds may vary locally.
  • The anode, which can conduct electricity and is in contact with the electrolyte, corrodes when it combines with the chemicals in the electrolyte.
  • A metal also contacts the electrolyte at the cathode. It is protected from corrosion rather than corroded.
  • Anode and cathode are connected by the conductor, which also completes the circuit.
