Explanation:
Hello!
In this case, for the given chemical reaction:
We can see a 4:2 mole ratio between lithium nitrate (68.946 g/mol) and lithium sulfate (109.94 g/mol); in such a way, via stoichiometry, the required mass of lithium nitrate to make 250 g of lithium sulfate turns out:
Best regards!
Explanation:
Nuclear energy is found in the nucleus of an atom holding nuclear materials in place.
When a nuclear decay or fusion occurs, the energy is released.
- Most times, the nuclear energy is transformed into heat energy.
- The heat energy is used to do other forms of work that converts energy from one form to another.
- It can be converted to mechanical energy when water is boiled and used to drive turbines.
- It can be used in heating chambers.
- this and many more can lead to energy transformation

I hope this helps Chemistry is so hard and I hate it
<u>Full Question:</u>
The list below includes some of the properties of butane, a common fuel. Identify the chemical properties in the list. Check all of the boxes that apply.
denser than water
burns readily in air
boiling point of –1.1°C
odorless
does not react with water
burns readily in air
does not react with water
<h3><u>
Explanation:</u></h3>
The type of alkane that is used in many products includes Butane. It is found as a natural gas in the environment. It is found on the deeper part of ground. It can be obtained by drilling process and gets used up in many of the products that is used for commercial purposes.
Molecular mass that is associated with butane is 58.12 g/mol. The boiling point of butane is -1 degree Celsius and -140 degree Celsius is its melting point. It is a liquefied gas and does not react with water. It will burn in air more readily.
