How much work is done by a 35-watt light bulb if it is on for 1,320 seconds?
OleMash [197]

Answer:

The 35-watt light bulb does a work of 46200 joules in 1320 seconds.

Explanation:

From Physics we remember the definition of work (W), measured in joules, by the following integral equation:

W = \int\limits_{0}^{t} {\dot W} \, dt (1)

Where \dot W is the power, measured in watts.

If the power is stable in time, then the work can be calculated by the following algebraic equation:

W = \dot{W}\cdot \Delta t (2)

If we know that \dot W = 35\,W and \Delta t = 1320\,s, then the work done by the 35-light bulb is:

W = (35\,W)\cdot (1320\,s)

W = 46200\,J

The 35-watt light bulb does a work of 46200 joules in 1320 seconds.

If 11.00 mL of a standard 0.2831 M NaOH solution is required to neutralize 26.86 mL of H2SO4, what is the molarity of the acid s
MrRa [10]

Answer:

0.1159 M

Explanation:

Using the formula below:

CaVa = CbVb

Where;

Ca = concentration/molarity of acid (M)

Cb = concentration/molarity of base (M)

Va = Volume of acid (mL)

Vb = volume of base (mL)

According to this question, the following information were given:

Ca = ?

Cb = 0.2831 M

Va = 26.86 mL

Vb = 11.00 mL

Using CaVa = CbVb

Ca × 26.86 = 0.2831 × 11

26.86Ca = 3.1141

Ca = 3.1141 ÷ 26.86

Ca = 0.1159

The molarity of the acid (H2SO4) solution is 0.1159 M

54.2 g N<br> determine the number of moles
Juliette [100K]

Answer:

3.87 mol N

General Formulas and Concepts:

<u>Chemistry - Atomic Structure</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis

Explanation:

<u>Step 1: Define</u>

54.2 g N

<u>Step 2: Identify Conversions</u>

Molar Mass of N - 14.01 g/mol

<u>Step 3: Convert</u>

<u />54.2 \ g \ N(\frac{1 \ mol \ N}{14.01 \ g \ N} ) = 3.86867 mol N

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

3.86867 mol N ≈ 3.87 mol N
