What chemical test can be carried out to show that a liquid collected from the sea is water? (color change if the liquid is water)

Answers

Answer 1

Answer:

Answer:

Explanation:

The chemical test for water includes the cobalt chloride paper test. If water is present it will change from blue to pink colour. Another test is the copper sulphate test. pure form of copper sulphate is white in colour.

Copper (II) sulphate is used to test for water. We use white anhydrous copper (II) sulphate, which contains no water. If water is present, the copper (II) sulphate turns blue. A positive test for the presence of water will mean the copper (II) sulphate turns blue.

Write a balanced chemical equation for the reaction of solid strontium with fluorine gas.

Answers

Answer:

Sr(s) + F₂(g) → SrF₂(s)

Explanation:

A balanced equation is an equation that has an equal number of atoms of elements on either side of the equation.
Chemical equations are balanced to obey the law of conservation of mass which states that the mass of reactants and that of the product should always be equal in chemical reactions.
Therefore, the balanced chemical equation for the reaction between Sr and F₂ is given by;

Sr(s) + F₂(g) → SrF₂(s)

Each side of the equation has 1 atom of Sr and two atoms of F thus the equation is balanced.

Final answer:

Solid Strontium reacts with Fluorine gas in a synthesis reaction to form Strontium Fluoride. The balanced chemical equation is Sr (s) + F2 (g) -> SrF2 (s).

Explanation:

The reaction of solid strontium (Sr) with fluorine gas (F2) is a synthesis reaction, and it forms strontium fluoride (SrF2). The balanced chemical equation for this reaction is:

Sr (s) + F2 (g) → SrF2 (s)

In this equation, 's' stands for solid, 'g' stands for gas, and the arrow ( → ) indicates the direction of the reaction from reactants to products.

What is the difference between a chemical process and a physical process in chemistry?

Answers

Answer & Explanation:

The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
