C. Hair dryer

Explanation:

Alternating Current

The other kind of electricity is called alternating current, or AC. Power plants produce this

type of electricity. It is carried by large power lines from the plant to your home. When you

plug a TV, a lamp, or a hair dryer into the wall socket, you are using this type of electricity.

Using a chemical equation to find moles of product from moles of reactant
kumpel [21]

Answer:

0.86 moles H₂O

Explanation:

To solve this problem, it is important to first determine the balanced chemical equation. The balanced equation is necessary as it will provide the mole-to-mole ratio needed to convert between moles O₂ and moles H₂O.

The unbalanced equation:

C₈H₁₈ (l) + O₂ (g) ---> CO₂ (g) + H₂O (g)

<u>Reactants:</u> 8 carbon, 18 hydrogen, 2 oxygen

<u>Products:</u> 1 carbon, 2 hydrogen, 3 oxygen

As you can see, the equation is not balanced because there are unequal amounts of each element on both sides. Balancing the equation is a matter of guessing-and-checking to see which combination of coefficients work.

The balanced equation:

2 C₈H₁₈ (l) + 25 O₂ (g) ---> 16 CO₂ (g) + 18 H₂O (g)

<u>Reactants:</u> 16 carbon, 36 hydrogen, 50 oxygen

<u>Products:</u> 16 carbon, 36 hydrogen, 50 oxygen

Now that the equation is balanced, we can use the coefficients of O₂ and H₂O to construct our mole-to-mole ratio and perform our conversion. The final answer should have 2 sig figs to match the given value (1.2 moles). The state of matter is most likely not necessary to include in your final answer.

1.2 moles O₂          18 moles H₂O
---------------------  x  -----------------------  =  0.86 moles H₂O
                                25 moles O₂

List one difference between blended fibres and regenerating synthetic fibres​
Mashcka [7]

Answer:

blended is better than synthetic fibre. because blended fabrics have quality of synthetic and natural fibres so they are more better than fabrics. For example terrycot. Blended Fibres are considered better than individual synthetic fibres because they show the advantages of 2 or more fibres.

Elanso [62]

<u><em>Answer:</em></u>

<u><em>49.98</em></u>

<u><em>Explanation:49.98 should be the correct answer but if you start with 49.98 g H2O2 and decompose all of it you do not get 34.00 g H2O and 15.98 g O2. </em></u>
