__C7H16+ ___O2=CO2 + H20 how to balance this equation​

Chemistry
1 answer:
Leokris [45]3 years ago
7 0

Answer:

C7H16 + 11O2 = 7CO2 + 8H2O

Explanation:

Start by balancing the C and H in C7H16 by adding the coefficient of 7 for CO2 because there are 7 C's in C7H16. Similarly, since there are 16 H's in C7H16, balance it by adding the coefficient of 8 to the H2O, which will result in 16 H's.

Finally, add up the O's on the right side and balance it by adding the appropriate coefficient on the O2. On the right, there are 22 O's, so balance the equation by adding the coefficient of 11 on the left for the O2.

Calculate the number of moles in 1.8gram of h2o<br>​
Rzqust [24]

Answer:

~.1058 Moles

Explanation:

The formula for this question is the following.

1 mole of a compound/molar mass of the compound.

First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.

1 mole of H2O/ 17.01 g/mol H2O

We now know that in 1 mole of H20 there is 17.01 g.

Take 1.8g and divide it by 17.01, you get your answer.

AnnyKZ [126]

Answer:

E

Explanation:

A miscelle has a an ionic head which is hydrophillic and interacts effectively with water, helping the miscelle to dissolve. The tail is hydrophobic, it dissolve the grease or stain and removes it from the fabric. The hydrophobic tail extends outside the water, while the hydrophillic head extends into the water. This enables the cleansing action of soap

Firlakuza [10]

Answer:

All of the above.

Explanation:

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.

This process is not reversible and a change of energy that is sometimes heat is given off.

Leya [2.2K]

Answer:

Moles of zinc chloride produced are 0.09942 moles.

Explanation:

Zn+2HCl\rightarrow ZnCl_2+H_2

Mass of zinc used = 6.5 g

Moles of zinc =\frac{6.5 g}{65.38 g/mol}=0.09942 mol

According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :

\frac{1}{1}\times 0.09942 =0.09942 mol of zinc chloride

Moles of zinc chloride produced are 0.09942 moles.
