How much heat is required to heat 5.25 g of water h2o from 5.5?
Evgen [1.6K]
Heat = mass * heat capacity of water * change in temperature mass = 5.25 g heat capacity of water = 4.186 joule/gram °C Change in temperature = 62.8°C - 5.3°C = 57.5 °C Plug in the values heat = 5.25 g * 4.186 joule/gram °C * 57.5 °C = 1263.6 J Rounded to two three significant figures, it is 1260 J of energy needed. In terms of calories, the heat capacity of water is 1 calorie/gram °C. So do the plugging in all over again. mass = 5.25 g heat capacity of water = 1 calorie/gram °C Change in temperature = 62.8°C - 5.3°C = 57.5 °C heat = 5.25 g * 1 calorie/gram °C * 57.5 °C = 301.9 calories Rounded to 3 significant figures, it is 302 calories Q=SM∆T=4.18*5.25*(62.8-4.3)=1280 J 1280 J * (1 cal/4.18 J) = 307 cal

A sample of gold (Au) has a mass of 35.12 g. what is the moles of each element for AU?
vlada-n [284]
To determine the number of moles(n) of a substance, divide its amount given in grams by the molar mass. The element in the problem is gold (Au) which has a molar mass of 196.97 grams per mole. The division is better illustrated below
 
                                     n = 35.12 g / 196.97 grams per mole

The answer to the operation above is 0.1783 moles. Therefore, there are approximately 0.1783 moles of Au in 35.12 grams.

How many electrons are needed in the outer energy levels of most atoms to be chemically stable?
Tatiana [17]
Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to 18 electrons.
