In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases. All definitions agree that bases are substances which react with acids as ... A ...

Acids are species with pH less than 7, while bases those with pH greater than 7. ... Using Arrhenius' definition, acids are those that produce the hydrogen ion when dissolved in water ( ) while bases produce the hydroxide ion ( ). These ions, when in water, act as charge carriers and can hence conduct electricity.

Acid–base reactions require both an acid and a base. ... For example, according to the Arrhenius definition, the reaction of B If inorganic, determine whether the compound is acidic.

4. A salvage operator recovered coins believed to be gold. A sample weighed 385.000g and has a volume of 20.0mL. Were the coins

aleksley [76]

Answer:

Gold

Explanation:

We are given that

Mass of sample ,m=385 g

Volume ,V=20mL

We have to find the coin is gold or yellow brass.

We know that

Density= $\frac{Mass}{volume}$

Using the formula

$Density=\frac{385}{20}g/mL$

$Density=19.25g/mL$

$Density\approx 19.3g/mL$

Density of coin=19.3g/mL

Density of gold=19.3g/mL

Hence, the coin is gold.

When 6.85×10⁵ cal is converted to kilojoules, the result obtained is 2866.04 KJ

<h3>Data obtained from the question </h3>

Energy (cal) = 6.85×10⁵ cal
Energy (KJ) =?

<h3>Conversion scale </h3>

1 cal = 0.004184 KJ

<h3>How to convert 6.85×10⁵ cal to kilojoules</h3>

1 cal = 0.004184 KJ

Therefore,

6.85×10⁵ cal = 6.85×10⁵ × 0.004184

6.85×10⁵ cal = 2866.04 KJ

Thus, 6.85×10⁵ cal is equivalent to 2866.04 KJ
