An alkane used as a lubricant contains 25 carbon atoms. How many hydrogen atoms are present in its structure?

Chemistry

nadya68 [22]3 years ago
5 0

Answer:

52

Explanation:

Alkanes are saturated hydrocarbons, that is, they are formed just by carbon and hydrogen atoms bonded through single covalent bonds. The general formula for alkanes is CnH2n+2.

If n = 25 (25 carbon  atoms), 2n + 2 = 2 × 25 + 2 = 52. There are 52 hydrogen atoms in the structure and the alkane has the formula C₂₅H₅₂.

Explain what happens in a nuclear chain reaction
Vesnalui [34]

Answer:

Nuclear Chain Reactions. A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. This nucleus in turn produces neutrons, and the process repeats. The process may be controlled (nuclear power) or uncontrolled (nuclear weapons).

If Log 4 (x) = 12, then log 2 (x / 4) is equal to
Alexus [3.1K]

The value of log₂(x/4) is 22. Using the properties of the logarithm, the required value is calculated.

<h3>What are the required properties of the logarithm?</h3>

The required logarithm properties are

logₐx = n ⇒ aⁿ = x; and logₐ(xⁿ) = n logₐ(x);

Where a is the base of the logarithm.

<h3>Calculation:</h3>

It is given that,

log₄(x) = 12;

On applying the property logₐx = n ⇒ aⁿ = x; here a = 4;

So,

log₄(x) = 12 ⇒ 4¹² = x

⇒ x = (2²)¹² = 2²⁴

Then, calculating log₂(x/4):

log₂(x/4) = log₂(2²⁴/4)

              = log₂(2²⁴/2²)

              = log₂(2²⁴ ⁻ ²)

              = log₂(2²²)

On applying the property logₐ(xⁿ) = n logₐ(x);

log₂(x/4) = 22 log₂2

We know that logₐa = 1;

So,

log₂(x/4) = 22(1)

∴ log₂(x/4) = 22.
