Answer:No rhinos are not a producer. Rhinos are a primary consumer. A producer for example would be a plant such as grass.
The heat required by the cube of iron has been 602.64 J.
The specific heat has been given as the amount of heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.
The heat required has been expressed as:

2.07 M is the molarity of the final solution if 45.0 ml of 6.00M HCl is added to 130 ml of O.
Explanation:
Data given:
volume of HCl, V1 = 45 ml
molarity of the HCl solution, M1 = 6 M
final volume of the HCl solution after water is added, V2 = 130 ml
final molarity M2 =?
After the dilution, the molarity of the new solution can be found by using the formula:
M1V1 = M2V2
here M1 and V1 are the molarity and volume for concentrated solution, M2 and V2 represents the diluted solution's molarity and volume.
Applying the formula after rearranging the equation, we get
M2 =
M2 =
M2 = 2.07 M
The final molarity of the HCl solution is 2.07 M
Answer:
True
Explanation:
Hardness is defined as the ability of a substance to resist being scratched. It can be described using Moh's scale
From the given, we can note that the material with hardness 8 has more resistance to being scratched that a material with hardness 7.
This means that if these two substances came in contact, the more hard substance will scratch the less hard substance.
Hope this helps :)
