Answer:

The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.

Balance the equation and show the calculation of the number of moles and grams of CO2 formed from 11.9 grams of O2. Show your an
n200080 [17]

Answer:

0.2349 moles, 10.3356 g

Explanation:

The given reaction is :

C_6H_{14}+O_2\rightarrow CO_2 + H_2O

The balanced reaction by equating the same number of each atom both side is :

2C_6H_{14}+19O_2\rightarrow 12CO_2 + 14H_2O

Given that :

Amount of oxygen gas = 11.9 g

Molar mass of oxygen gas = 32 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus, moles are:

moles= \frac{11.9\ g}{32\ g/mol}

moles= 0.3719\ mol

From the reaction,  

19 moles of oxygen gas on reaction forms 12 moles of carbon dioxide

Also,

1 mole of oxygen gas on reaction forms 12/19 moles of carbon dioxide

So,

0.3719 moles of zinc on reaction forms \frac {12}{19}\times 0.3719 mole of carbon dioxide

<u>Moles of carbon dioxide formed = 0.2349 moles</u>

Mass of carbon dioxide = moles×Molar mass

Molar mass of carbon dioxide = 44 g/mol

<u>Mass of carbon dioxide formed = 0.2349 ×44 g = 10.3356 g</u>

When a sample of aqueous hydrochloric acid was neutralized with aqueous sodium hydroxide in a calorimeter, the temperature of 10
Annette [7]
<span>6.50x10^3 calories. Now we have 4 pieces of data and want a single result. The data is: Mass: 100.0 g Starting temperature: 25.0°C Ending temperature: 31.5°C Specific heat: 1.00 cal/(g*°C) And we want a result with the unit "cal". Now you need to figure out what set of math operations will give you the desired result. Turns out this is quite simple. First, you need to remember that you can only add or subtract things that have the same units. You may multiply or divide data items with different units and the units can combine or cancel each other. So let's solve this: Let's start with specific heat with the unit "cal/(g*°C)". The cal is what we want, but we'ld like to get rid of the "/(g*°C)" part. So let's multiply by the mass: 1.00 cal/(g*°C) * 100.0 g = 100.0 cal/°C We now have a simpler unit of "cal/°C", so we're getting closer. Just need to cancel out the "/°C" part, which we can do with a multiplication. But we have 2 pieces of data using "°C". We can't multiply both of them, that would give us "cal*°C" which we don't want. But we need to use both pieces. And since we're interested in the temperature change, let's subtract them. So 31.5°C - 25.0°C = 6.5°C So we have a 6.5°C change in temperature. Now let's multiply: 6.5°C * 100.0 cal/°C = 6500.0 cal Since we only have 3 significant digits in our least precise piece of data, we need to round the result to 3 significant figures. 6500 only has 2 significant digits, and 6500. has 4. But we can use scientific notation to express the result as 6.50x10^3 which has the desired 3 digits of significance. So the result is 6.50x10^3 calories. Just remember to pay attention to the units in the data you have. They will pretty much tell you exactly what to add, subtract, multiply, or divide.</span>

How many grams of glucose(C6H12O6) are produced by 10.0 grams of water(H2O)?
GaryK [48]

Answer:

16.7 g of glucose

Explanation:

Convert grams of H₂O to moles.  <em>0.555 mol</em>

We can use the chemical equation to determine the theoretical yield.  Based on the equation, for every 6 moles of H₂O, 1 mole of glucose is produced.  The ratio of glucose moles to H₂O moles is 1/6.  

Multiply the moles of H₂O by the ratio to find moles of glucose.  <em>0.0925 mol</em>

Convert moles of glucose to grams.  <em>16.7 g</em>
