<span> The Reactants are Zinc (Zn) and Sulfur (S).
The Product is Zinc Sulfide (ZnS).
All of them are solids.
The combined masses of the reactants must be 14 grams, too. Later in Chemistry you'll learn that's not really true, but it is for now.
Hope This Helps:)

How much energy is released when 65.8 g of water freezes

Delvig [45]

The amount of energy released is calculated by the product of heat of fusion and mass. The formula of amount energy released is given by: $q= L\times m$ (1)

Here,

q is amount of energy released L is heat of fusion ( $334 J/g$ ) m is mass of water Put all the given values in equation (1)

$q= 334 J/g \times 65.8 g$

$q= 21977.2 Joules$ ≅ $21977 Joules$

$q= 21977 Joules$

Thus, amount of energy released is $21977 Joules$

Write this number in standard notation.<br> 1.986 x 10negative exponent 6 or 1.986 x 10^6

Brums [2.3K]

Answer:

$0.000001986$

Explanation:

We have the number $1.986*10^{-6}$ . Standard notation would basically be this number without the $10^{-6}$ part.

To get rid of this part, we need to move the decimal point 6 places to the left (we go left because it's negative 6, indicating division).

So, when we move the decimal point 6 places to the left, the resulting number is: $0.000001986$ , with 5 zeros after the decimal point before a nonzero number.

Thus, the answer is $0.000001986$ .
