Answer:
the energy of the products is less than the energy of the reactants.
Explanation:
the the change is enthalpy is negative, and heat is released to the surroundings.
Answer:
0.259 nm is the distance between the red and green balls.
Explanation:
Let the distance between the red and green ball be = RG =x
Let distance between blue and red ball = RB =y = 0.448 nm
Let distance between blue and green ball = GB = z
In triangle RGB
( Pythagoras theorem)
..[1]
In triangle GOB
( Pythagoras theorem)
GO = OB = sides of cube
..[2]
Using [2] in [1]:
0.259 nm is the distance between the red and green balls.
Answer:
780 g
Explanation:
Step 1: Given data
Moles of sodium phosphate: 4.76 moles
Step 2: Calculate the mass corresponding to 4.76 moles of sodium phosphate
To convert moles to mass, we need a conversion factor. In this case, we will use the molar mass of sodium phosphate, which is 163.94 g/mol.
4.76 mol × 163.94 g/mol = 780 g
It reduces the chance of an extinction given a natural disaster. If there is more diversity and lets say a wildfire happens, more species would survive the event to repopulate the area
