Answer:
H₂0_{(s)} + heat → H₂O(l)
Explanation:
An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.
On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.

Answer:
C
Explanation:
Because you can feel vibrations through solids but not through gases
Answer:
The answer is definitely Water
The force on the charge is 1.1×10⁻⁸ N.
<h3>What is force?</h3>
Force can be defined as the product of the mass of a body and its acceleration
To calculate the force on the charge, we use the formula below.
Formula:
- F = qvBsin∅............. Equation 1
Where:
- q = charge
- v = velocity
- B = magnetic field
- ∅ = Angle.
From the question,
Given:
- B = 25 mT = 0.025 T
- v = 250 m/s
- q = 3.5 nC = 3.5×10⁻⁹ C
- ∅ = 30°
Substitute the given values into equation 1
- F = (0.025)(250)(3.5×10⁻⁹)(sin30°)
- F = 1.093×10⁻⁸ N
- F ≈ 1.1×10⁻⁸ N
Hence, the force on the charge is 1.1×10⁻⁸ N.
