How many atoms of oxygen are in 3 molecules of CaSO4?
Chemical name for CaSO4 is calcium sulphate. It has 4 oxygen atoms in 1 molecule. So it has 12 oxygen atoms in 3 molecules.
There are 3 grams of magnesium and 2 grams of oxygen if 4 grams of magnesium oxide is produced and all of the magnesium was used up how many grams of oxygen are left?
If 3 grams of magnesium are used to form 4 grams of magnesium oxide, then 1 gram of oxygen is used in the reaction. This means 1 gram of oxygen remains unused.
What is the elements make up in iron phyrophosphate?
Pyrophosphate has the chemical formula (P2O7)-4. It is a class of chemical anions that were originally formed from heating (pyro) phosphates. They are formed by esterification of two phosphates (linking them with one of the phosphate oxygen atoms).
What is a compound containing 3 atoms of carbon and 8 atoms of hydrogen combined in a reaction with oxygen molecules?
C3H8 (butane) + 5 O2 (oxygen) --> 3 CO2 (carbon dioxide) + 4 H2O (water)
In very sample of carbon monoxide the mass ratio of carbon to oxygen is 34?
in every sample of carbon monoxide ,the mass ratio of carbon to oxygen is 3:4
In a school a fourth of a class are boys. What fraction are girls?
A fourth of the class are boys, which can be expressed as a fraction as 1/4. Since the class is made up of only boys and girls, and a fourth of the class are boys, the remaining part of the class must be girls. To find the fraction of the class that are girls, you can subtract 1/4 from 1. 1 - 1/4 = 3/4 So, 3/4 of the class are girls.
