Answer:
Solar Energy.
Explanation:
There is more solar radiation hitting their surface, which means they can produce more electricity. Solar energy is more valuable in places with expensive electricity. If two solar panel systems in different cities have the same energy output, savings will be greater in the city with the highest kWh prices.
Answer:
Increasing Surface Area
Explanation:
A greater surface area (meaning more, smaller particles) allows for more opportunity for particles to collide. On the other hand, decreasing temperature and removing a catalyst would only decrease the number of collisions, and the clumping option doesn't make much sense. Hope this helps!
Answer:
12.044 ×10²³ molecules of HCl
Explanation:
Given data:
Number of moles of MgO = 1 mol
Number of molecules of HCl react = ?
Solution:
Chemical equation:
MgO + 2HCl → MgCl₂ + H₂O
with 1 mole of MgO 2 moles of HCl are react.
Number of molecules of HCl react:
1 mole contain 6.022×10²³ molecules
2 mol × 6.022×10²³ molecules / 1 mol
12.044 ×10²³ molecules
Answer:

Explanation:
The density of a substance can be found by using the formula
From the question
mass = 30 g
volume= 25 mL
We have
We have the final answer as
<h3>1.2 g/mL</h3>
Hope this helps you
Answer:Acceleration due to gravity is 9.8m/s per second. During the next second you are already falling at 9.8m/s and accelerating to 19.6m/s. So you fall another 9.8 meters, plus 4.9 meters to account for the acceleration. During the third second, you fall 19.6 meters plus 4.9 meters to accout yet again for acceleration.
