Answer:
Yes. u can because its easy to tell if an item will sink or float usually by the weight or the width
Explanation:
Answer: B) has a small negative value.
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
As there are 5 moles of gaseous reactants and 4 moles of gaseous products, the gaseous molecules are decreasing on moving from reactants to products, thus randomness decreases and is negative.
Thus has a small negative value.
A= liquid core
B= solid core
c= mantle
d= crust
Answer:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.
