Answer:
82 days would take a distance like that, if we drive at 120 mi/h
Explanation:
Distance from Earth to moon is 3.8×10⁵ km
You drive at a speed of 120 mi/h
Let's convert the 120 mi/h to km/h
1 mi = 1.61 km
Then 120 mi . 1.61 km / 1mi = 193.2 km
New velocity is 193.2 km. Therefore,
193.2 km are driven in 1 hour
3.8×10⁵ km woul be driven in (3.8×10⁵ . 1)/ 193.2 = 1966.8 hours
1967 hours . 1 day / 24 hours = 82 days
Answer:
4.46
Explanation:
Applying,
pH = -log(H⁺)....................... Equation 1
Where H⁺ = Hydrogen ion concentration of HCl solution
From the question,
Given: H⁺ = 3.5×10⁻⁵ M
Substitute these values into equation 1
pH = -log(3.5×10⁻⁵)
pH = 4.46
Hence the pH of HCl solution is 4.46
Answer:
The answer should be 2 because to balance the equation you should have to change to equation to this; 2Al + 3Br2 => 2AlBr3, so that there is a total of 2 Aluminums and 6 Bromiums on either side of the equation.
Explanation:
I believe the correct answer is C it would make the value of the left side equal to 4 and the value to the right side also equal to 4
