First, you need grams but you have moles.
Find out the total molar mass of SiO₂
Si = 28.085 g/mol Si
O₂ = 32 g/mol O₂
Add them together to get the molar mass
28.085 g/mol Si + 32 g/mol O₂ = 60.085 g/mol SiO₂
Multiply the molar mass of SiO₂ by the number of moles you have of the same substance:
60.085 g/mol SiO₂ × 0.125 mol SiO₂ =
7.51 grams SiO₂
Answer:
A charged particle experiences a force when moving through a magnetic field. ... If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. i hope this helped you! have a great day
Explanation:
Changes of state are physical changes in matter. They are reversible changes that do not change matter's chemical makeup or chemical properties. For example, when fog changes to water vapor, it is still water and can change back to liquid water again.please mark brainliest if correct
There is a high density on water and not on gas
The Correct choice is D. Fe + S = FeS
because, in nature Iron (Fe) and Sulphur (S) are found in mono - Atomic form. so, There will be 1 Fe atom reacting with 1 S atom to form FeS (Iron sulphide)
