A student has four resistors. Each resistor has a resistance of 100 ohms.
ValentinkaMS [17]

Answer:

The minimum resistance is 25 ohms.

Explanation:

Resistance of each resistor is 100 ohms. When resistors are connected in parallel, the equivalent resistance is lowest. For parallel combination, the equivalent resistance is given by :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....

Here, all resistors are 100 ohms. So,

\dfrac{1}{R}=\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}\\\\R=25\ \Omega

So, the minimum resistance is 25 ohms.

Calculate ΔHrxn for the following reaction: C(s) + H2O(g) --> CO(g) + H2(g) Use the following reactions and given ΔH values:
valentina_108 [34]

Answer:

ΔH = 130.5 kJ

Explanation:

Hello,

In this case, by using the Hess law, we compute the enthalpy of the required reaction:

C(s) + H2O(g) --> CO(g) + H2(g)

Thus, the first step is to keep the following reaction unchanged:

C (s) + O2 (g) → CO2 (g), ΔH = -393.5 kJ

Next, we invert and halve this reaction:

2 CO (g) + O2 (g) → 2 CO2 (g), ΔH= -566.0 kJ

So the enthalpy of reaction is inverted and halved:

CO2 (g) → CO (g) + 1/2 O2 (g) ΔH= 283 kJ

Then, we also invert and halve this reaction:

2 H2 (g) + O2 (g) → 2 H2O ΔH= -483.6 kJ

So the enthalpy of reaction is inverted and halved as well:

H2O → H2 (g) + 1/2 O2 (g) ΔH= 241.8 kJ

Finally, we add the three reactions to obtain the required reaction:

= C (s) + O2 (g) + CO2 (g) + H2O → H2 (g) + <u>1/2 O2</u> (g) + CO (g) + <u>1/2 O2 (g)</u> + CO2 (g)

= C (s) + <u>O2 (g)</u> + <u>CO2 (g) </u>+ H2O → H2 (g) + <u>O2 (g)</u> + CO (g) + <u>CO2 (g)</u>

= C (s) + H2O → H2 (g) CO (g)

So enthalpy is computed by:

ΔH = -393.5 kJ + 283 kJ + 241.8 kJ

ΔH = 130.5 kJ

Best regards.

#2 Compare the number of moles of each element on both sides of the reaction. Write the results in the following space.
vredina [299]

Explanation:

This is the photosynthesis equation in which green plants manufacture their food.

During photosynthesis, green plants combine carbon dioxide with water to produce glucose and oxygen gas.

 The equation is as shown below:

    6CO₂    +     6H₂O        ⇒         C₆H₁₂O₆      +     6O₂

This reaction is a typically balanced equation and by all means, we must have the same number of moles of reactants and products.

Solving:

     Reactants                                                            Products

Elements        Number of moles                                Number of moles

   C                               6                                                           6

   H                                12                                                         12

    O                               18                                                         18

Using the coefficients, one should be able to determine the number of moles of each element.
