After mg ribbon is reacted completely with air, what is the reason to add some water and heat?

1 answer:

3 0

The reason why some water and heat are added after Mg ribbon is reacted completely with air is to remove Mg3N2 as MgO.

Combustion reaction is a reaction in which a substance is completely burnt in oxygen. Magnesium ribbon can be converted to magnesium oxide by combustion in air.

The reaction is as follows; 2Mg(s) + O2 ----> 2MgO(s)

Since air contains nitrogen, Mg3N2 is also formed. Heat and water can be added to the reaction thereby converting magnesium nitride to magnesium oxide.

What is the most important role that water plays for living organisms

LuckyWell [14K]

-well, we all need water as living organisms in order to live. water helps us clean our body (just like you clean yourself in a shower to clean your skin),but drinking water helps you to take a shower inside your body! (sounds weird but true XD) you get the point... here are a few things water does to our body:

- water helps helps our skin to look beautiful (you can say youthful skin) and even beauty itself.

- it trashes body waste and toxins (like i said above)

- it gives us nutrients and minerals

- it helps us to maintain out blood pressure

- it also helps to regulate our body temperature

- it transfers oxygen through the whole body

- it helps with digestion

- weigh loss

- gives you energy ( thats why when your exercising you need to drink water every 15 min XD)

-prevents from you have a stinky breath *-*

- it helps with back-pain, headaches, heart health...etc

- it helps boost your immune system

- increases your brain power

so those are what i got for you about why water is important to us :D

The half life for the decay of carbon- is years. Suppose the activity due to the radioactive decay of the carbon- in a tiny samp

EleoNora [17]

The question is incomplete. The complete question is:

The half-life for the decay of carbon-14 is 5.73x10^3 years. Suppose the activity due to the radioactive decay of the carbon-14 in a tiny sample of an artifact made of woodfrom an archeological dig is measured to be 2.8x10^3 Bq. The activity in a similiar-sized sample of fresh wood is measured to be 3.0x10^3 Bq. Calculate the age of the artifact. Round your answer to 2 significant digits.

Answer:

570 years

Explanation:

The activity of the fresh sample is taken as the initial activity of the wood sample while the activity measured at a time t is the present activity of the wood artifact. The time taken for the wood to attain its current activity can be calculated from the formula shown in the image attached. The activity at a time t must always be less than the activity of a fresh wood sample. Detailed solution is found in the image attached.
