Do you think you could go a week

Chemistry
1 answer:
Alinara [238K]3 years ago
5 0

Answer:

The answer to your question is No

Explanation:

I think it is impossible to go a week without causing any chemical reaction. For example, if a drive my car or motorcycle, I am burning fuel and that is a combustion reaction.

Also, I want to cook, all this process involves a lot of chemical reactions among the components of food and maybe water.

If I take a shower or wash my hands, between the soap and the microbes occur are some chemical reactions that help to remove these organisms.

Also, when I wash my clothes something similar happens.  

These are some examples of the chemical reactions that happen daily but I think there are a lot more.

In which system does a spontaneous redox reaction produce electrical energy?
Vladimir [108]
Had to look for the options and here is my answer.
When we say that a redox reaction is spontaneous, this would mean that there is a formation of positive voltage <span>across the electrodes of a voltaic cell. Therefore, the system that this kind of reaction produces electrical energy is in a GALVANIC CELL. Hope this helps.</span>

Under certain conditions, the substance ammonium chloride can be broken down to form ammonia and hydrogen chloride. If 29.4 gram
lina2011 [118]

Answer: 20.0 g of hydrogen chloride must simultaneously be formed

Explanation:

The balanced chemical reaction is :

NH_4Cl\rightarrow NH_3+HCl

According to the law of conservation of mass, mass can neither be created nor be destroyed. The mass on reactant side must be equal to the mass on product side.

Thus mass of reactants = mass of products

Given : mass of ammonium chloride = mass of reactants = 29.4 g

mass of ammonia = 9.4 g

mass of products = mass of ammonia + mass of hydrogen chloride

9.4 g +mass of hydrogen chloride = 29.4 g

mass of hydrogen chloride = 20.0 g
