What are factors that determine when a substance is toxic and unfit to human consumption?
Various factors determine if a substance is toxic and unfit for human consumption, including its chemical composition, dosing level, route of exposure, and individual susceptibility. Toxicity can also depend on how the substance interacts with the body's biological systems and its potential to cause harm or adverse effects. Regulatory authorities set safety standards to safeguard public health and ensure that substances in consumer products or food are safe for consumption.
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What is Avogrado's constant?
*Avogadro's Constant is 6 x 10^23, representing the number of particles (ie. atoms/ions/molecules) in one mole of any substance :)
As long as conditions such as what do not change the density of a substance dose not change?
As long as the temperature and pressure remain constant, the density of a substance will not change. Density is determined by the mass of a substance and its volume, and as long as these factors remain constant, the density will remain the same.
What happens to a substance's temperature as it god through the change of state?
During a change of state, the temperature of a substance remains constant. This is because the energy being added or removed is used to break or form intermolecular bonds rather than increase or decrease the substance's kinetic energy.
What is Avogadro number the constant for?
Avogadro's constant is the number of atoms or molecules of a substance in 1 mole of that substance.
What is a pure substance classified as?
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
How do you calculate the decay constant for a radioactive substance?
The decay constant for a radioactive substance is calculated by dividing the natural logarithm of 2 by the half-life of the substance. The formula is: decay constant ln(2) / half-life.
What classifies a substance as a pure substance?
A pure substance is a substance that is constant throughout. Such as water, tin or sulfur.
How can one determine the decay constant of a radioactive substance?
To determine the decay constant of a radioactive substance, one can measure the rate at which the substance decays over time. By analyzing the amount of radioactive material remaining at different time intervals, scientists can calculate the decay constant, which is a measure of how quickly the substance decays.
What matter has a definite or constant composition?
Substance
What is the significance of energy meter constant?
the value 'n' of meter constant indicates that consumption of energy is n KWh.
Why does a substance have a constant flow rate if all variables remain constant?
because i have bstl
What is the similarties between mixture and substance?
A substance has constant and definitive composition Mixture is combinations of pure substances that have no constant and definitive composition: homogeneous mixture, heterogeneous mixture
What are some examples of constant variables in science?
A constant variable is a variable that gets changed by a physical substance
How do you use avagardos constant?
Avogadro's constant (6.022 x 10^23) is used to convert between the number of particles (atoms, molecules, ions) and the amount of substance (moles) in a sample. You can use Avogadro's constant to calculate the number of particles in a given amount of substance or to determine the amount of substance from the number of particles.
How do you calculate the solubility constant for a given substance?
To calculate the solubility constant for a substance, you need to measure the equilibrium concentration of the dissolved substance in a saturated solution and use it in the equilibrium expression for the dissolution reaction. The solubility constant (Ksp) is then calculated by taking the product of the concentrations of the dissolved ions raised to the power of their stoichiometric coefficients.
