Answer:
H₄SiO₄
Explanation:
From the question given above, the following data were obtained:
Hydrogen (H) = 4 moles
Oxygen (O) = 4 moles
Silicon (Si) = 1 mole
Empirical formula =?
Since the number of mole of each atom of the element present is known, the empirical formula of the compound can be written as follow:
H₄SiO₄
Answer:
The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of protons and neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons.
The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.[2] It was coined by a Scottish doctor and writer Margaret Todd in 1913 in a suggestion to chemist Frederick Soddy.
The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.
For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that the neutron numbers of these isotopes are 6, 7, and 8 respectively.
Answer:
hydration reaction
Explanation:
The type of reaction would be hydration reaction.
<u>Hydration reaction generally involves a chemical reaction of water with another reactant and in which the water ends up being converted to another product entirely. </u>
A good example of hydration reaction is the reaction between alkene and water leading to the production of alcohol.
⇄ 
Answer:
a. True
Explanation:
Molecule -
- It refers to a group of two or more than two atoms , which can exists freely on it own , is referred to as a molecule .
- The molecule is a neutral group , where the atoms are bounded by chemical bonds .
- Molecule have a characteristic property of the substance.
Hence, the given statement about molecule , is true.
Answer: Weak acids are poor conductors of electricity.
Explanation:
Weak acids are defined as the acids which dissociate weakly or partially when dissolved in water (polar solvent).
For example, 
Due to less dissociation there will be less number of ions present in a solution of weak acid. As a result, a weak acid will be poor conductor of electricity.
As electricity is the flow of ions.
Thus, we can conclude that weak acids are poor conductors of electricity.
