Please help me, I am not very good at these. i don't know how to tell the differences Cl2 + 2NaBr 2NaCl +Br2 is what type of reaction?
a, combustion
b, decomposition
c, single-replacement
d, synthesis
e, replacement​

What is the single most important equation in all of physics?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
