Rust forms when _____ reacts with chemicals in rocks.

Answers

Answer 1

Answer: Rust forms when oxygen reacts with chemicals in rocks, and that is often the case with many other elements in general. Like a copper nail being exposed to the air will rust.

Answer 2

Answer:

Answer : Rust forms when oxygen reacts with chemicals in rocks.

Explanation :

Rusting : It is a chemical process in which an iron react with oxygen to give an iron(III)oxide as a product. The product iron(III)oxide formed from the chemical reaction is known as rust.

The chemical reaction will be,

$4Fe+3O_2\rightarrow 2Fe_2O_3$

Hence, rust forms when oxygen reacts with chemicals in rocks.

Atoms contain small, negatively charged particles.

Answers

Atoms contains small, negatively charged particles. His experiment showed that an atom contains negatively charged particles which was later known as electrons. This was confirmed by the Cathode Ray Experiment he conducted.

Answer: The correct statement is atoms contain small, negatively charged particles.

Explanation:

J.J.Thomson was a scientist which discovered electrons that are present in an atom.

He did an experiment and gave a model for this. The experiment conducted by him was Cathode Ray experiment and the model given by him was Plum pudding model.

From cathode ray, he showed that the cathode ray was composed of a negatively charged particles and named it as electrons. From plum pudding experiment, he said that the electrons are embedded in the atom. These particles carry negative charge and are very small as compared to the atom.

Hence, the correct statement is atoms contain small, negatively charged particles.

Answer:

Rutherford's atomic model explained how the electrons surrounded the nucleus of protons and neutrons. His model showed how J. J. Thomson's Plum Pudding model was incorrect.

Answer:Rutherford model of an atom shows that an atom is mostly an empty space,with electrons orbiting a fixed positively charged nucleus in set.

Which information about a chemical reaction is provided by a potential energy diagram?(1) the oxidation states of the reactants and products(2) the average kinetic energy of the reactants and products
(3) the change in solubility of the reacting substances
(4) the energy released or absorbed during the reaction

Answers

Answer: (4) the energy released or absorbed during the reaction

Explanation: Potential energy diagram is the representation of energy with the course of reaction. It shows the energy of reactants, activation energy which is the energy required by the reactants to cross the energy barrier and the energy of the products.

Thus the difference of energy of products and energy of reactants gives us the energy released or absorbed during the reaction.

$\Delta H=E_P-E_R$

where $\Delta H$ = enthalpy of reaction

$E_P$ = energy of products

$E_R$ = energy of reactants

If $E_P$ > $E_R$ , energy is absorbed and reaction is endothermic

$E_P$ < $E_R$ , energy is released and the reaction is exothermic.

D. The energy released or absorbed during the reaction

How many moles of Cr are in 156 g of the element?a. 1.0 mol
b. 3.0 mol
c. 6.5 mol
d. 156 mol

Answers

Mole measure the number of elementary entities of a given substance that are present in a given sample. 3 mole of Cr are in 156 g of the element. The correct option is option B.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically, mole and molar mass of chromium can be related as :

number of mole =given mass of chromium÷ molar mass of chromium

Mass of chromium=156 g

Molar mass of 1 mole of chromium= 51.9961 g/mol

Substituting the given values we get,

number of mole =156 g ÷ 51.9961 g/mol

number of mole= 3

Therefore, the correct option is option B. 3 mole of Cr are in 156 g of the element.
