Where did the fahrenheit temperature scale get its name?
____ [38]

Answer:

Daniel Gabriel Fahrenheit

Explanation:

he 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30° and 90° for the freezing point of water and normal body temperature, respectively; these later were revised to 32° and 96°, but the final scale required an adjustment to 98.6° for the latter value.

A sample of gas occurs 9.0mL at a pressure of 500mmHg. A new volume of the same sample is at 750mmHg. Use two significant figure
Rufina [12.5K]

Answer:

\large \boxed{\text{6.0 mL} }

Explanation:

The temperature and amount of gas are constant, so we can use Boyle’s Law.

p_{1}V_{1} = p_{2}V_{2}

Data:

\begin{array}{rcrrcl}p_{1}& =& \text{500 mmHg}\qquad & V_{1} &= & \text{9.0 mL} \\p_{2}& =& \text{750 mmHg}\qquad & V_{2} &= & ?\\\end{array}

Calculations:  

\begin{array}{rcl}500 \times 9.0 & =& 750V_{2}\\4500 & = & 750V_{2}\\V_{2} & = &\dfrac{4500}{750}\\\\& = & \textbf{6.0 mL}\\\end{array}\\\text{The volume of the gas is } \large \boxed{\textbf{6.0 mL}}

An electromagnetic wave that has a lower frequency than infrared radiation will have ____ than the infrared radiation. longer wa
Monica [59]
Answer: longer wavelength and lower energy.

Explanation:

1) The wavelength is inversely related to the frequency. So, an electromagnetic wave with lower frequency will have longer wavelength.

This is the formula for electromagnetic waves:

λ = c / ν

where λ is the wavelength, c is the speed of light, and ν is the frequency.

2) Energy is directly related to the frequency.

This is the formula E = hν,

where E is the energy, h is Planck constant, and ν is the frequency.

So, the lower the frequency the lower the energy.

3) Conclusion:
<span>An electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength and lower energy than the infrared radiation</span>

PLEASE HELP
Step2247 [10]

Answer:

See explanation

Explanation:

The equation of the reaction is;

C3H8 + 5O2 ----> 3CO2 + 4H2O

Number of moles of C3H8 = 132.33g/44g/mol = 3 moles

1 mole of C3H8 yields 3 moles of CO2

3 moles of C3H8 yields 3 × 3/1 = 9 moles of CO2

Number of moles of oxygen = 384.00 g/32 g/mol = 12 moles

5 moles of oxygen yields 3 moles of CO2

12 moles of oxygen yields 12 × 3/5 = 7.2 moles of CO2

Hence C3H8 is the limiting reactant.

Mass of CO2 produced = 9 moles of CO2 × 44 g/mol = 396 g of CO2

1 moles of C3H8 yields 4 moles of water

3 moles of C3H8 yields 3 × 4/1 = 12 moles of water

Mass of water = 12 moles of water × 18 g/mol = 216 g of water

b) Actual yield = 269.34 g

Theoretical yield = 396 g

% yield = actual yield/theoretical yield × 100/1

% yield = 269.34 g /396 g × 100

% yield = 68%
