Does milk help dilute some poison?
Yes, but it depends on the poison. Where a poison is a corrosive, milk may limit damage to the lining of the throat and stomach, as well as absorption into the bloodstream.Contact a Poison Control Center for any ingested poison.US number : 1-800-222-1222UK number (NHS helpline): 0845 4647
How can one calculate the extinction coefficient of a protein?
To calculate the extinction coefficient of a protein, you can use the formula: Extinction coefficient (A11cm) / (number of amino acids x molecular weight). A11cm is the absorbance at 280 nm for a 1 cm path length. This value can be determined experimentally using a spectrophotometer.
How can I effectively measure algae growth for my science fair project?
To effectively measure algae growth for your science fair project, you can use a spectrophotometer to measure the absorbance of light by the algae, a microscope to count the number of algae cells, or a fluorometer to measure chlorophyll content. These methods will provide quantitative data on the growth of the algae over time.
What is the purpose of the energy?
Energy meter works on the same principle as the induction motor. An aluminium disc is placed inside a magnetic core with two limbs. One carries a voltage coil so its flux is proportional to voltage, the second carries a current coil so its flux is proportional to current. The two fluxes induce eddy currents into the disc, each of which interacts with the flux of the other to produce a torque, which accelerates the disc. This torque of course is proportional to flux × the eddy current, which equates to V × I, or power. A permanent magnet creates another eddy current resulting in a torque proportional to speed that brakes the disc, the combined result of these actions is that the speed of the disc is proportional to power, and the total number of revolutions is proportional to the energy that has passed through the meter. The disc drives a chain of gears that turn a mechanical counter, called a 'register'.
How does an individuals hematocrit correlate to the erythrocyte count?
The hematocrit is also called the erythrocyte volume fraction, which is the percentage by volume of red blood cells in the blood. Erythrocyte is another name for the red blood cell in humans, so the higher the count, the larger the hematocrit.
What are the units of absorbance?
Absorbance is a dimensionless quantity and has no units. It is calculated using the formula A = log10(I0/I), where A is absorbance, I0 is the intensity of the incident light, and I is the intensity of the transmitted light. Since it is a logarithmic ratio of two intensities, absorbance is expressed simply as a number, typically ranging from 0 to 3 for most applications.
Does absorbance increase or decrease as the solution concentration of the substance increase?
Absorbance typically increases as the solution concentration of a substance increases. This is because absorbance is directly proportional to the concentration of the absorbing species, as described by the Beer-Lambert Law. As more molecules of the substance are present in the solution, more light is absorbed, leading to higher absorbance readings.
What is the pH number for dilute hydrochloric acid?
Dilute hydrochloric acid typically has a pH around 1 to 2.
What is the sensitivity directly proportional to in atomic absorption spectrometry?
The sensitivity is directly proportional to the number of atoms in ground state.
What is the sensitivity directly proportional to in atomic emission spectrometry?
The sensitivity is directly proportional to the number of atoms in the excited state.
Is 7 and 9 proportional?
You CAN'T determine whether two numbers are proportional, just by looking at one number from each set.
Are the atomic mass and atomic number directly proportional to each other?
No, atomic mass and atomic number are not directly proportional to each other. Atomic mass represents the average mass of isotopes of an element, while atomic number represents the number of protons in an atom's nucleus. These values are related but not directly proportional.
What is indirectly proportional?
"indirectly proportional" appears to be interchangeable with "inversely proportional."When a dependent variable is inversely proportional to an independent variable, that means it decreases as the dependent one increases, and vice versa. For example, a baseball player's batting average is inversely proportional to the number of at-bats. (It's directly proportional to the number of hits he gets.) In other words, as the number of at-bats increases, the player's batting average decreases. Another example is gravitational attraction between two bodies. The gravitational force between two bodies is inversely proportional to the square of the distance between them.
Is pressure directly proportional to the number of moles in a given system?
Yes, pressure is directly proportional to the number of moles in a given system, according to the ideal gas law.
Is the volume of a gas directly or inversely proportional to the number of particles in a gas?
Directly proportional, at pressure and temperature constant.

What is mass proportional to the number that makes up an object?
