Ciara’s bike has rusted, which means that the iron in the metal changed to rust.
What has occurred?
an energy formation
an exothermic reaction
a chemical reaction
a precipitate formation
Answer:
CChem Reaction
Explanation:
Cuz it big brain time
The iron in the metal changed to rust, which is a chemical reaction. Therefore, option (C) is correct.
What is the rusting of iron?The rusting of iron is an oxidation reaction in which the iron combines with oxygen in the air in the presence of water to produce Fe₂O₃.xH₂O, a hydrated iron (III) oxide.
This hydrated iron (Ill) oxide is rust and the color of rust is reddish-brown. This reddish-brown rust can be seen on iron nails, pipes, and railings. on. Rust is formed when the iron is exposed to oxygen in the presence of moisture and is not an instantaneous reaction. Rusting of iron takes place over a long period of time.
Fe (s) + O₂ (g) + xH₂O (l) → Fe₂O₃. xH₂O (s)
The oxidation state of iron increases which is followed by the loss of electrons as a result of the rusting reaction. Iron(III) oxide or ferric oxide has the iron atom has an oxidation state of +3.

Do you think MgO has a higher or lower
melting point than NaCl? Why?
Answer:
Magnesium Oxide (MgO) has a higher melting point than Sodium Chloride (NaCl) which is around 2,800 degrees Celcius. This is because its Mg2+ and O2- ions have a greater number of charges, and so form stronger ionic bonds, than the Na+ and Cl– ions in Sodium Chloride.

What is the mass of 1.2 mol IrI3?
Answer:
690 g IrI₃
Explanation:
To convert from moles to grams, you have to use the molar mass of the compound. The molar mass of IrI₃ is 572.92 g/mol. You use this as the unit converter in this equation:
[tex]1.2molIrI3 * \frac{572.92g}{1mol} = 687.504 g IrI3[/tex]
Round to the lowest number of significant figures which is 2 to get 690 g IrI₃.

the banana that Mila ate had energy? Explain why you think this
Answer:
Explanation:
In this case, the fitness magazine compared the food we eat with a battery because the food provides energy for the human body to perform its daily activities.
The banana is an excellent source of energy, as it is a fruit with a high content of carbohydrates and fructose, it is an excellent food to be eaten before physical exercise, as it provides the muscles with enough energy to increase performance before and after exercise. , is a fruit rich in potassium, magnesium, phosphorus, and vitamins a and c, which gives greater strength and energy.

Which describes 5 molecules of water?
1. 2 H2O
2. H2O3
3. 5 H2O
5 molecules of water is 5 H2O.
One water , H2O. molecule consist of one oxygen atom bonded with two atoms of hydrogen. The structure of water molecule is bent. Water is a polar compound. Oxygen is more electronegative than the hydrogen atom. The oxygen atom get partial negative charge and the hydrogen atoms get partial positive charge. Water is a universal solvent. The hydrogen and oxygen atoms are held together by a covalent bond . covalent bond is formed by the sharing of electrons between the two atoms. water The chemical name of water is Dihydrogen monoxide.

Answer:
Gravitational energy, electric energy, magnetic energy, nuclear energy, thermal energy, chemical energy.
Explanation:
gravitational energy - the energy resulting from the attraction of two masses to each other
electric energy - energy from a static or moving electrical charge.
magnetic energy - energy from the attraction of opposite magnetic fields, repulsion of like fields, or from an associated electric field
nuclear energy - energy from the strong force that bonds protons and neutrons in an atomic nucleus
thermal energy - also called heat, this is energy that can be measured as temperature. It reflects the kinetic energy of atoms and molecules
chemical energy - energy contained in chemical bonds between atoms and molecule
mechanical energy - the sum of the kinetic and potential energy

1Which statement about plant cells is true? A A plant cell cannot contain both a nucleus and chlorophyll. Incorrect answer B A plant cell can contain both chlorophyll and a nucleus. Incorrect answer C A plant cell must contain chlorophyll, but can have no nucleus. Incorrect answer D A plant cell has neither a nucleus nor chlorophyll.
Answer:
B A plant cell can contain both chlorophyll and a nucleus.
Explanation:
All plants are eukaryotic organisms i.e the cells of all plants possess a membrane-bound nucleus that houses their genetic material (DNA). In addition to this, most plant cells also contain a unique organelle called CHLOROPLAST, which they use to capture the energy from sunlight in order to perform a process called PHOTOSYNTHESIS.
According to this question, plant cells can contain both chlorophyll and a nucleus. They can possess chlorophyll because chlorophyll is a pigment in their chloroplast that captures the light energy.
