According to le châtelier’s principle, the amount of solid reactant or product present does not have an impact on the equilibriu
Inessa05 [86]

The concentration of solids is constant and usually taken equal to unity ,therefore it does not appear in the equilibrium constant ,so adding or removing solid has no effect. So According to Le Chatelet's Principle the amount of solid reactant or product present does not have an impact on the equilibrium

What is  Le Chatelet's Principle ?

The position of the equilibrium in a chemical reaction can be predicted with the aid of Le Chatelet's Principle in response to changes in temperature, concentration, or pressure. This is crucial, especially for industrial applications where it's crucial to predict and maximize yields.

According to Le Châtelet's principle, if a dynamic equilibrium is upset by changing the conditions, the equilibrium position will move to compensate for the change and restore the equilibrium.

A sample obtained from the national bureau of standards had a calibrated weight of 20.000. When it was used tocalibrate a studen
melisa1 [442]

Answer : The measurements are both precise and accurate.

Explanation :

Accuracy : It is defined as the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by first person is more accurate.

Precision : It is defined as the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

When the level of precision is very very less, the measurement can be considered as most precise and most accurate.

As we are given the standard value of the sample is 20.000 and the values measured by the balance are, 19.995, 20.005, 20.001.

Since these three values are in the range of +/- 0.005 from one another. So, we can say that the measurements are both precise and accurate.

Hence, the measurements are both precise and accurate.

Who discovered the first real evidence of the big bang?
Sonbull [250]
The scientist who discovered the first real evidence of the big bang was EDWIN HUBBLE.
Astronomer Edwin Hubble was an American astrophysicist. He contributed in so many ways to humanity during his lifetime. One of his contribution is that, his observation showed the existence of galaxies that are far beyond the milky way; these galaxies were moving away from one another. This observation serves as a concrete evidence for the big bang theory, which explain the origin of the universe.
