A person walking covers 5.20 m in 10.4 s. How fast is the person moving?
salantis [7]

Answer:

<h2>0.50 m/s</h2><h2></h2>

Explanation:

Velocity = distance over time

where distance = 5.20 m

                   time = 10.4 s.

velocity = <u>  5.20  m </u>

                  10.4 s.

            = 0.50 m/s

Once an enzymatic reaction is completed, the enzyme releases what?
sleet_krkn [62]

Answer:

Once an enzymatic reaction is completed, the enzyme releases substrates.

Explanation:

The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

What is the mass of carbon in 500. g of octane?
denis23 [38]

The answer is: the mass of carbon is 420.6 grams.

m(C₈H₁₈) = 500 g; mass of octane.

M(C₈H₁₈) = 114.22 g/mol; molar mass of octane.

n(C₈H₁₈) = m(C₈H₁₈) ÷ M(C₈H₁₈).

n(C₈H₁₈) = 500 g ÷ 114.22 g/mol.

n(C₈H₁₈) = 4.38 mol; amount of octane.

In one molecule of octane, there are eight carbon atoms:

n(C) = 8 · n(C₈H₁₈).

n(C) = 8 · 4.38 mol.

n(C) = 35.02 mol; amount of carbon.

m(C) = 35.02 mol · 12.01 g/mol.

m(C) = 420.6 g; mass of carbone.

Unlike an acid, an aqueous solution of a base
HACTEHA [7]

Answer:

D) contains more OH– ions than H+ ions

Explanation:

THESE ARE THE OPTIONS FOR THE QUESTION

A) causes some indicators to change color B) conducts electricity C) contains more H+ ions than OH– ions D) contains more OH– ions than H+ ions

Base can be regarded as substance which can dissociates in water then form hydroxide ions (OH–) .

Bases can be regarded as compounds which break into hydroxide ions I.e (OH-) with more other compounds if put in an aqueous solution. Hence it contains more OH– ions
