<h3>Answer:</h3>

B) 4H₂(g) + O₂(g) ⟶ 2H₂O(l)

<h3>Explanation:</h3>
  • Chemical reactions occur when compounds or elements combine to form new compounds or other elements.
  • Chemical reactions may be classified into various types which include synthesis reactions, replacement reaction, decomposition reactions, and precipitation reactions among others.
  • In our case, we were supposed to identify a synthesis reaction.
  • Thus, we need to know what is a synthesis reaction.
  • A synthesis reaction is a reaction that occurs when two elements or small compounds combine to generate a large compound.
  • In this case, B is the choice that shows a synthesis reaction where hydrogen gas combines with oxygen gas to yield water.

A force of 350 N causes a body to move with an acceleration of 10 m/s2. What's the mass of the body?
Scrat [10]
You have to use the equation F=ma and solve for m to get m=F/a.
m=mass in kg
F=force (in this case 350N)
a=acceleration (in this case 10m/s²)
when you plug everything in you should find that m=35kg

I hope this helps.
