Answer:
C because it only has one????
Answer: The Ions move freely in water and carry electric charges
Explanation:
The answer to this question is change in temperature will be 6.1 and specific specific heat capacity of metal will be 1698.36.
According to the formula of Calorimetry
Q = msΔT
where, Q = Quantity of heat absorbed (in joules)
M = Mass of water sample given (in kilogram)
S = specific heat capacity of metal
ΔT = Change in temperature
We have given,
Mass as 25 gram which is equal to 0.025 Kg.
Change in temperature as 6.1
Quantity of heat absorbed as 259 J
Applying to the formula of Calorimetry
Q = msΔT
259 = 0.025 × s × 6.1
s = 1698.36
So, specific heat capacity of metal came out to be 1698.36 and the change in temperature will be 6.1

Answer: different charges but same mass
protons and neutrons determine the mass (electrons are too light)
since atom q and atom r are of the same proton and neutron , they are of the same mass
protons and electrons determine the charge
a proton has a 1+ and electron has a 1- charge
atom q has no charge, the protons and electrons cancel each other out
atom r has a 1- charge as there is one more electron than proton.
1 cent ----------> 0.01 g
52 cent ---------> g
g = 52 * 0.01
answer 0.52 g
hope this helps!.
