1.Heat:Heat can cause rock to melt,forcing real changes in its chemical and physical makeup;forcing some elemental components to chemically react with each other,both internal and external,chemical components to form entirely new material.

As with any combustion reaction, the products of combusting a hydrocarbon fuel (CxHy) with oxygen (O2) are carbon dioxide (CO2)

melisa1 [442]

Answer:

5 molecules of oxygen will be present 

Explanation:

In this reaction combustion is taking place hence there must be presence of oxygen in it.

We don't know the initial amount of carbon molecules in hydrogen molecules present hence the equation goes:-

$CxHy + O_2 => CO_2+ H_2O$

Mass of fuel 16.74 grams, Mass of carbon dioxide is 1198 gram and water is 0.0654 remaining mass of fuel is 16.70 g. Hence amount of fuel used up is 0.04 gram

 $0.04 + O => 0.1198 + 0.0654$ 

Weight of products is 0.1852 and weight of oxygen is 0.1452 

No of molecules will be $\frac {(0.1452 \times 6.023 \times 10^-^2^3)}{ (1.661 \times 10^-^2^4)} = 5$ molecules

In this project, you will research the harm that can be done to your health by environmental factors. Using the resources of you

Wooahhhh pollution can affect the environment and urself pollited water can affect marine animals and can result them in extinction global warmning melts Antarctica and can cause floodigs and extinction there. This probably wont help but i just free styled lol
Goodluck

sam records the mass of his evaporating dish as 8.365 g. he records the mass of the evaporating dish and the sample of hydrate a

guapka [62]

0.2701 moles of water were evaporated from the sample by the heating process

Mass of evaporating dish = 8.365 g

mass of dish + hydrate = 18.597 g

mass of hydrate = (mass of dish + hydrate) - mass of dish

hydrate = 18.597 - 8.365 = 10.232 g

Mass of dehydrated material = (mass of dish + dehydrate ) - mass of dish

dehydrated material = 18.735 - 8.365 = 5.37 g

Mass of water evaporated = hydrate - dehydrate

mass of water = 10.232 - 5.37 = 4.862 g

Molar mass of water = 18 gm/mol

no. of moles of water evaporated = mass / molecular mass

moles = 4.862/18 = 0.2701 moles
