Answer:
(ΔHrxn) = 1.273kJ/mol
Explanation:
Applying
m=78.2, c= 3.97, ∆t= 25.8-21.7
(ΔHrxn)= mc∆t
=78.2× 3.97× 4.1= 1.273kJ/mol
<span>Pillow lavas have pillow-like structures and are formations that push lava on the surface of the earth underwater. Magma comes out of ocean ridges as pillow lava and forms a new oceanic crust, supporting sea floor spreading. The older crust gets pushed away from the ridge and pushes on to the continents, making them drift.</span>
Answer:
TRUE
Explanation:
An Equipment grounding conductor are used to ground a non current-carrying metallic parts of any equipment. Its main function is to keep the equipment close to the ground potential as possible and is also allows a safer path for the ground-fault current to flow. If the equipment is grounded, all the excess current will go to the ground and will not damage the equipment.
Hence the answer is TRUE.
.4 M means that in 1 Liter of solution there are .4 moles.
Molarity x Liters = Moles
We have molarity, so convert mL to liters
250 mL x 1000mL/1 Liter = .25 L
Now, set up the equation
.4 M x .25 L = .1 moles of solute
