Answer:
last choice
Explanation:
Specific heat of a metal is j/kg-c
It says nothing about melting point or heat of fusion
A = twice B = 2 * j/kg-c B = j/kg-c
if j is constant and mass is the same we can write this more like
A = 2 /C and B = 1/C
or A ~ C/2 and B~ C
now you can see that the temp change in A will be 1/2 that of B
5 protons and six neutrons
Answer:
Backbone
Explanation:
Organisms that have backbones are known as vertebrates, while the ones without a backbone are classified as invertebrates.
Answer:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
Explanation:
Reactants;
Calcium hydroxide = Ca(OH)₂
Hydrogen chloride = HCl
Products;
Calcium chloride = CaCl₂
Water = H₂O
The reaction equation:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
The reaction is a neutralization reaction where acids reacts with bases to produce salt and water only.
