Answer:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
Explanation:
From Physics we remember the definition of work (
), measured in joules, by the following integral equation:
(1)
Where 
is the power, measured in watts.
If the power is stable in time, then the work can be calculated by the following algebraic equation:
(2)
If we know that 
and 
, then the work done by the 35-light bulb is:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
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
I think It's a value that depends on another
Answer and Explanation:
The substance that does the dissolving (or dissolves in the solution) is the <u>solute</u>.
- The solute is the substance that is being dissolved
The substance that makes the solute dissolve is called the <u>solvent.</u>

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 />
= 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
