Correct Answer: Option C: <span>oxygen and hydrogen

Reason:
</span>When a metal bonds with a non-metal, the bond is formed due to transfer of electron from metal to non-metal. This bond is referred as ionic bond. <span>On the other hand, when two non-metallic elements are bond, there is sharing of electrons. And the compound so formed is called as </span>molecular compound<span>. In present case, both oxygen and hydrogen are non-metal. Hence, the compound so formed (H2O) is called molecular compound. </span><span>

In the winter, a heated home in the Northeast might be maintained at a temperature of 78°F. What is this temperature on the Cels

masya89 [10]

Answer: $25.6^0C$ , $298.6K$

Explanation:

Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like $^0C$ and $K$

These units of temperature are inter convertible.

We are given:

Temperature of the gas = $78^0F$

Converting this unit of temperature into $^0C$ by using conversion factor:

$^oC=\frac{5}{9}\times (^oF-32)$

$^0C=\frac{5}{9}\times (78^oF-32)$

$25.6^0C$

Converting this unit of temperature into $K$ by using conversion factor:

$K=t^0C+273$

$K=25.6+273$

$298.6K$

Thus the temperature on the Celsius and Kelvin scales are $25.6^0C$ and $298.6K$ respectively.

Acellus<br> How many grams of strontium<br> (Sr, 87.62 g/mol) are in 2.92<br> moles of strontium?

saul85 [17]

Answer:

There are 255, 85 grams of Strontium in 2,92 moles.

Explanation:

We perform a simple rule of three to calculate the number of grams, knowing that one mole of Sr weights 87, 62 grams:

1 mol Sr---------87, 62 grams

2,92 mol Sr-----x=(2,92 mol Sr x-87, 62 grams)/1 mol Sr= 255,8504 grams
