Eart's rain and snow come from the Marine ecosystem, which is the largest of the aquatic ecosystems on Earth!
Answer:
53.2%
Explanation:
- Write the mass of the elements in your molecule:
Mass of Si in 1 mol SiO2 =28.1g
Mass of O in 1 mol SiO2 =16x2g= 32g
- Now find the mass of your compound
Mass of compound= 28.1+32=60.1
- Divide each element's mass by the mass of the compound to find the percent by mass following this formula:
% by mass = (mass of element/mass of compound) x 100
% by mass of oxigen= (32g/60.1) x 100
% by mass of oxigen= 53.2%
I hope you find this information useful and interesting! Good luck!
Answer:
continental polar
Explanation:
The large air mass that is moving into the area is a continental polar one. As we can see on the map, the air mass is moving in from the northern part of North America toward the Central part of North America. It is an air mass that has been formed over land, thus it is a continental one, and since it has been formed on a very high latitude it is a polar one too. This type of air mass brings in very cold weather, often resulting in large amounts of snowfall as well, thus it is causing severe snow storms.
Answer:
36-(-64) is =100.
From the rule of sign Multiplications
When two negatives interact by Multiplication.... They become Positive.
So
36-(-64) = 36+64 = 100.
Have a great day!
Answer:
The coriolis force
Explanation:
Rotation causes a deflection of ocean and air currents, the rotation of the earth is much faster than the winds or movement of the currents and this causes a deflection.
