yes I doso u need to find the amount of grams total and the individual amount of grams.so 40+40+52+16+16+16+16=196g (I got the numbers from the periodic table)K- 80gCr-52gO-64gsince you are solving for oxygen, you would only use the oxygen part so...64g/196g=32.9%32.9% is the answer hope this helps! if it doesn't, let me know in the comments! have a blessed day!
Answer:
2:1
Explanation:
The first step in this type of question is ensure yourself that the chemical is balanced. After establishing that, you read off the answer from the stoichiometric coefficients (the numbers in front of the formula) of potassium bromide and bromine and write those as the ratio, the molar ratio to be more specific.
Answer:
C18H38(s) + O2(g) → CO₂(g) + H₂O(g).
Explanation:
C₁₈H₃₈ is called Octadecane and it is an Alkane as the molecular formula follows the general formula of Alkanes which is CnH2n+2 .
C₁₈H₃₈ reacts with Oxygen and forms Carbon Dioxide (CO₂) and Water (H₂O).
We can say that on oxidation Octadecane gives Carbon Dioxide (CO₂) and Water (H₂O) because on passing Oxygen over Octadecane the above products are formed.
C18H38(s) + O2(g) → CO₂(g) + H₂O(g).
Answer
Its D

this is easy!! also i shall give u a gift a cute bee
So its temperature will not rise, since kinetic energy of molecules remains the same. The quantity of heat absorbed or released when a substance changes its physical phase at constant temperature (e g. From solid to liquid at melting point or from liquid to gas at boiling point) is termed as its latent heat.
