Answer:
The mass of silver is 49 g (0.049 kg).
Explanation:
Initial temperature = 
C
Final temperature = 
C
Quantity of heat required = 117.5 J
Specific heat capacity of silver = 0.240 J/g
mass of the silver can be determined by;
Q = mcΔθ
Where: Q is the quantity of heat required, m is the mass of substance, c is the specific heat capacity of the substance and Δθ is the change in temperature.
So that,
117.5 = m x 0.240 x (40 - 30)
117.5 = m x 0.24 x 10
= 2.4m
m = 
= 48.9583
m ≅
m = 49 g
The mass of silver is 49 g (0.049 kg).
Atomic mass = 39
number of neutrons = 20
Number of protons= 19
Electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1
The number of electron in first shell = 2
number of electrons in n=3 shell = 8
Measurement is a process of finding a number that shows the amount of something.
Brainliest? Thanks!
B, it's properly because of convection! Please, correct me if I'm wrong :>
Answer:
An ionic compound whose aqueous solution conducts an electric current is called a(n) electrolyte
Explanation:
Electrolytes are substances that contain anions and cations and is therefore able to conduct the electric current.
For example: NaCl
NaCl → Na⁺ + Cl⁻
