The heat absorbed during vaporization is called the heat of vaporization. For carbon tetrachloride, the heat of vaporization is 30.5 kJ/mol. To calculate the heat absorbed when 75 g of CCl4 vaporizes, you would first convert grams to moles using the molar mass of CCl4. Then, use the heat of vaporization to calculate the total heat absorbed.
There are 15 moles of HCl present in 75 mL of a 200 M solution. To calculate this, first convert 75 mL to liters (0.075 L), then use the formula Molarity = moles/volume to find moles. So, 200 M = x moles / 0.075 L. Solving for x gives you 15 moles of HCl.
Rhenium has 75 protons, 75 electrons and 111 neutrons.The number of protons is equal to the number of electrons.Neutrons can be calculated by subtracting the number of protons from the atomic weight.In this case atomic number is 186 ==> the nr of neutrons = 186-75=111.
There are approximately 58.33 pennyweights in 75 grams.
Rhenium, with the chemical symbol Re, is the chemical element with the atomic number 75.
wavelength=velocity/frequency (v/f). wavelength=(3x10/4x10)=30/40=.75 meters
With the information given, it's not possible to calculate what it is now. But during that 90 minutes, its average velocity was 50 kph north.

To find the distance traveled, we can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. The initial velocity is 75 miles per second, the final velocity is 145 miles per second, and the time is 15 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time. Plug in the values to find the acceleration and then calculate the distance traveled in 15 seconds.
To calculate the distance traveled while the velocity is increasing, you can use the formula: distance = initial velocity * time + 0.5 * acceleration * time^2. In this case, the initial velocity is 75 m/s, the final velocity is 145 m/s, the acceleration is constant, and the time is 15 seconds. Plugging these values into the formula will give you the distance the plane travels during the acceleration period.
(60*75)/100=45
find 75% of 10 and 75%of 8 then add them together
Red is in the range of 635-700 nanometers (nm).
Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
What is the wave length of 100 Hz? Answer You mean a sound wave in air. At a temperature of 20 degrees Celsius or 68 degrees Fahrenheit there is the speed of sound c = 343 meters per second. For a tone of f = 100 Hz the wavelength is lambda = c / f = 343 / 100 = 3.43 meters.The equation for the relationship between wavelength and frequency is X = frequency * wavelength, where X = the speed of the particle. For light, the wavelength of 100 Hz is 2.99 E8 cm, and for sound, the wavelength is 60 m.
Velocity = Distance ÷ Time : therefore, Time = Distance ÷ Velocity. Time = 1 ÷ 75 = 0.01333 hours = 0.8 minutes = 48 seconds.
To find what is 75% of 250: 75 ÷ 100 × 250 = 187.5
