BA(OH)2 (Barium hydroxide)
Barium hydroxide is a chemical compound with the chemical formula Ba(OH)₂ₓ. The monohydrate, known as baryta or baryta-water, is one of the principal compounds of barium.
Answer:
The right choice is "burning gas → pan → water → eggs"
Explanation:
Heat will flow from the body of higher temperature to the cooler body.
So, heat will firstly flow from burning gas to pan by conduction then to the water in contact with pan then to the egg present inside the water.
<u>So, the right choice is :</u>
"burning gas → pan → water → eggs"
we find the number of moles with the formula
pV=nRT
27C=300k
3.2*30=n*0.082*300
n=96/24.6=3.9 moles
we have the mass ant the number of moles so we can calculate the molar mass
283.3/3.9=72.64g/moles
that means X's mass is 72.64/2=36.3 so the element is Kr(Kriptonium)
Answer:
Phosphorus atoms can bond with oxygen atoms to form ester groups. These can bond with carbon atoms, yielding a large number of organic phosphorus chemicals. These are found in many important biological processes
- The difference between single displacement reaction and double displacement reaction are:
Explanation:
in the chemical reaction an atom in a molecule is replaced by another atom forming the end product .this type of chemical reaction involved only two reactants for example zinc + copper sulphate give us copper sulphate + copper.double displacement reaction is the reaction in which two compounds react together to form two other compounds by mutual exchange of other ions is called double displacement reaction.this type of reaction is involved two or more than two reactants.for example AG and O3 + NaCl give us agcl + nano3
