Answer:
20.4 Miles
Explanation:
If Terry's riding speed is reduced by 3mph, he would be riding at 12mph.
12*1.7 = 20.4 miles
(miles per hour literally means how many miles you can travel in an hour at your current speed)
From the formula PE = mgh, find h.
Divide both sides for mg (because we have them) so we have PE/mg = mgh/mg
h = PE/mg
h = 4620 J/ (56 kg * 9,8 N/kg)
h = 4620 J / 548.8 N = 8.4 m (circa)
Answer:
The answer to your question is No
Explanation:
I think it is impossible to go a week without causing any chemical reaction. For example, if a drive my car or motorcycle, I am burning fuel and that is a combustion reaction.
Also, I want to cook, all this process involves a lot of chemical reactions among the components of food and maybe water.
If I take a shower or wash my hands, between the soap and the microbes occur are some chemical reactions that help to remove these organisms.
Also, when I wash my clothes something similar happens.
These are some examples of the chemical reactions that happen daily but I think there are a lot more.
Mass of AlCl₃ : 93.39 g
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M
the volume of the solution = 330 cm³=0.33 dm³
the concentration of the solution = 283 g/dm³
mass of AlCl₃ :
Trees are a renewable resource that can be used as an energy source.
