Observe the chemical reaction below, and identify if the equation is balanced or not. If it is not balanced, then what coefficient should you place for the reactants and products? Justify with scientific reasoning.
Mg + O2---------> MgO
Make sure to include the following details in your answer in complete sentences:
- Is the chemical reaction balanced?
- Is it following the law of conservation of mass, why is not following?
- What can you do to make sure that the equation becomes balanced and follow the law?
Answers
Answer:
- The chemical reaction is not balanced. There is two oxygens on the reactant's side while there's only one oxygen on the products side.
- I would not say it's following the law of conservation of mass as it's not a balanced equation.
- To balance this equation, you would need to add the coefficient of '2' to Magnesium (Mg) on the reactants side, and add the coefficient of '2' to the products side. This would make it so that there's 2 Mg's and 2 O's on both the reactant's side and products side.

Answers
Answer:C
Explanation:
Got it right in usatestprep
The physical evidence that indicates that there has been a chemical reaction is that the beaker changes temperature and the correct option is option C.
What is Neutralization reaction?
Neutralization is a chemical reaction in which acid and base react to form salt and water. Hydrogen (H⁺) ions and hydroxide (OH⁻ ions) react with each other to form water.
The strong acid and strong base neutralization have a pH value of 7.
The beaker gets warm which indicates that the reaction between acid and base is an exothermic reaction releasing heat energy into the surroundings.
Therefore, The physical evidence that indicates that there has been a chemical reaction is that the beaker changes temperature and the correct option is option C.

En una botella hay 2x10 25 moléculas de vinagre puro ¿Cuántos mol y cuántos gramos de esta sustancia habrá en la botella?
Answers
Answer:
33.2 moles y 1994 gramos.
Explanation:
¡Hola!
En este caso, dado que es posible para nosotros relacionar moles con gramos por medio de la masa molar y moléculas con moles por medio del número de Avogadro, resulta factible para nosotros primero calcular las moles en las moléculas dadas y de esta manera luego calcular los gramos, teniendo en cuenta una masa molar de 60.05 g/mol ya que el vinagre se puede estudiar como ácido acético (CH3COOH):
[tex]2x10^{23}molec*\frac{1mol}{6.022x10^{23}molec}=33.2mol[/tex]
Seguidamente, calculamos los gramos:
[tex]33.2mol*\frac{60.05g}{1mol}=1994g[/tex]
¡Saludos!

Imagine that you are Andreas Vesalius. Write a short autobiographical statement that talks about who you are, where you’re from, and some of your important contributions.
Answers
Answer:
My name is Andreas Vesalius and I'm a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, De Humani Corporis Fabrica Libri Septem. I am often referred to as the founder of modern human anatomy. I was born in Brussels, December 31, 1514 which was then part of the Habsburg Netherlands. I was a Flemish doctor who was notable for my contribution to the science of anatomy of the human body. I was the first to perform public dissection on a human corpse, a practice that was unusual in the Middle Ages due to spiritual beliefs.
