tatuchka [14]3 years ago
4 0

Answer:

We can make 10 percent solution by volume or by mass. A 10% of NaCl solution by mass has ten grams of sodium chloride dissolved in 100 ml of solution. Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water.

Explanation:

have a good day

Sophie [7]

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

How do scientists determine the number of neutrons in an isotope of an atom? O They find the number of protons. 0 They add the n
Elza [17]

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.

In a certain chemical process, water reacts with a compound, and the water is converted into another compound during the reactio
gtnhenbr [62]

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.

CH_2=CH_2(g)   +   H_2O(g)  ⇄  CH_3CH_2OH(g)

Weak acids are poor conductors of:
valentina_108 [34]

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, CH_3COOH \rightleftharpoons CH_3COO^{-} + H^{+}

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.
