Answer:
I think C
Explanation:
because hydrogen on the right side only have two while on the left side it have 4
Answer:
balanced
Explanation:
its balance since all the elments add up on both sides
Answer:
A) Ca(s) + C(s) + 3/2 O₂(g) → CaCO₃(s)
Explanation:
Standard enthalpy of formation of a chemical is defined as the change in enthalpy durin the formation of 1 mole of the substance from its constituent elements in their standard states.
The consituent elements of calcium carbonate, CaCO₃, in their standard states (States you will find this pure elements in nature), are:
Ca(s), C(s) and O₂(g)
That means, the equation that represents standard enthalpy of CaCO₃ is:
<h3>A) Ca(s) + C(s) + 3/2 O₂(g) → CaCO₃(s)</h3><h3 />
<em>Is the equation that has ΔH° = -1207kJ/mol</em>
The graph of the plot of acceleration against force is a straight line graph. Option B
<h3>What is the relationship between force and acceleration?</h3>
From the Newton's second law of motion we can derive that; F = ma
F= mass
a = acceleration.
This implies that the acceleration and the mass of a body has a linear relationship. We could then assert that the force is directly proportional to the acceleration with the mass being the constant in the equation.
As such, the force that is imparted to the body is what determines the acceleration and the both increases or decreases linearly. Thus the graph of the plot of acceleration against force is a straight line graph. Option B
