Answer:
Newton's first law of motion describes inertia. According to this law, a body at rest tends to stay at rest, and a body in motion tends to stay in motion, unless acted on by a net external force
Answer:
A or C
Explanation:
C- rivers erode the land and stuff with the fast moving currents
A- no idea what that is but if needed to guess it’s a zone for tides tides do something similar to rivers with erosion I’d go with C though sorry if wrong
Answer:
It predicts whether or not a reaction will be spontaneous.
Explanation:
The equation;
∆G= ∆H - T∆S enables us to obtain the Gibbs free energy of a chemical process.
The Gibbs free energy value tells us whether a chemical process will be spontaneous or not.
When;
∆G>0 the reaction is not spontaneous
∆G=0 the reaction is at equilibrium
∆G<0 the reaction is spontaneous
The given reaction Mg + O₂ → MgO is a type of Synthesis reaction. Hence option (1) is correct.
<h3>What is Synthesis reaction ?</h3>
Synthesis reactions are reactions that occur when two different atoms or molecules interact to form one molecule or compound.
It is also known as combination reaction
In the given reaction Mg and O combines with each other to form one product i.e, MgO. Hence, The given reaction Mg + O₂ → MgO is a type of Synthesis reaction. Thus, option (1) is correct.
