How many significant figures are needed in the answer when 1.31m is multiplied by 6.5 m​
dmitriy555 [2]

Answer:

two

Explanation:

The number of significant figures needed in the answer is 2.

This is because when finding the products of two numbers, the result is as accurate as the least number of significant figures of the numbers being multiplied.

Here the numbers being multiplied are;

 1.31m

 6.5m

        1.31m has 3 significant figures

          6.5m has 2 significant figures.

So, the product will have 2 significant figures

How does atomic radius change from top to bottom in a group in the periodic table?
suter [353]
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.

Which of the following most accurately represents John Dalton’s model of the atom? A. a tiny, solid sphere with an unpredictable
valkas [14]

The most accurately represented John Dalton's model of the atom is: C. a tiny, solid sphere with a predictable mass for a given element

<h3>Further explanation</h3>

The development of atomic theory starts from the first term conveyed by Greek scientists who suggested that every substance has the smallest particles so that the word atomos appears, which means it cannot be divided. So, John Dalton, a British scientist put forward the hypothesis about atoms, among others:

  • 1. The elements are composed of atoms which are small particles which cannot be subdivided
  • 2. Atoms that make up the same element have the same properties, mass, and size, while for different elements, the properties are also different
  • 3. Compounds are composed of two or more atoms in a fixed ratio
  • 4. In chemical reactions, atoms after and before a reaction cannot be destroyed, only separation and reassembly occur

Point 3 shows the relationship with The Law of Constant Composition of Proust so that further research on atoms is more developed

Dalton's hypothesis is described as a solid sphere like a very small shot put ball or a bowling ball based on Dalton's hobby in bowling
