Answer:
Option D. ZnCl₂ and H₂
Explanation:
From the question given above, the following equation was obtained:
2HCl + Zn —> ZnCl₂ + H₂
Products =?
In a chemical equation, reactants are located on the left side while products are located on the right side i.e
Reactants —> Products
Now, considering the equation from the question i.e
2HCl + Zn —> ZnCl₂ + H₂
The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.
Thus, option D gives the correct answer to the question.
Beryllium has 4 protons, 4 electrons and 5 neutrons
Answer:
9kg
Explanation:
According to Newton's second law, Force=Mass x Acceleration.
Since we have the Force and the Acceleration, we can plug the values in and solve for mass using this equation:
90N = Mass x 10m/s
Divide both sides by 10:
90/10=Mass x 10/10
Mass = 9
The Mass of the object is 9kg.
Hope this helped!
Answer:
B
Explanation:
Solar power takes in light and turns it into a usable energy. if used in a vehicle that would take light energy and transform it into mechanical energy.
