Since mole ratio of magnesium to hydrochloric acid is 1:2, the answer is 1 mole of HCL.
In a gas, the partcles are very far apart and loose.
The method is called the displacement method.
You place some water in the graduated cylinder and measure its volume.
Then you add your object and measure the new volume.
The difference between the two volumes is the volume of your object.
Volume of a cube = mass/density
mass=100grams
density=1g/cm^3
volume is therefore= 100grams / 1gram/cm^3= 100cm^3
Answer:
True
Step-by-step explanation:
Roots grow into cracks in the rocks, as the roots grow, they press on the sides of the crack, making it wider until it breaks apart (example - tree roots breaking up the sidewalk. Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart.
