Answer: When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is 
.
Explanation:
The word equation is given as maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas.
Now, in terms of chemical formulae this reaction equation will be as follows.
Here, number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
To balance this equation, multiply HCl by 4 on reactant side and multiply 
by 2 on product side. Therefore, the equation can be rewritten as follows.
Hence, number of atoms on reactant side are as follows.
Number of atoms on product side are as follows.
Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.
Thus, we can conclude that when maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is .

The option which accurately defines kinetic energy from the choices above is:
the energy an object has because of its motion
The correct answer choice is option c
In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.
<h3>What is energy?</h3>
Energy can simply be defined as the capacity of doing work.
Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.
The unit of energy joules.
Other examples of derived quantities just like energy too are:
- Volume
- Speed
- Acceleration
- Density.
- Upthrust
- Momentum
- Momentum
- Power
- Pressure
- Force
Below are some few forms of energy; these are:
- Kinetic energy
- Potential energy
- Mechanical energy
- Solar energy
- Light energy
- Chemical energy
So therefore, the option which accurately defines kinetic energy from the choices above is:
the energy an object has because of its motion

Answer: 1.25 miles per minute
Explanation:
Average speed is the rate of change of total distance covered per unit time.
i.e Average speed = (Total distance / Time taken)
Total distance covered = (25miles + 40 miles + 70 miles + 15 miles)
= 150 miles
Total time taken = ( 15 minutes + 30 minutes + 1 hour + 15 minutes) = 120 minutes
Since 60 minutes = 1 hour, the total time taken is 120 minutes
Now, apply Average speed = (Total distance / Time taken)
= (150 miles / 120 minutes)
= 1.25 miles per minutes
Thus, Joseph drove with an average speed of 1.25 miles per minute.
Answer:
yes
Explanation:
yes because the ice changes forms physically and can be changed back. not 100% sure tho
