Answer:
At No is 6 ... By definition the Atomic Number of an element is defined by the number of protons in its nucleus.
Explanation:
At No => #protons in nucleus
At Mass => ∑(#p⁺ + #n°); n° = no. neutron in nucleus.
The final temperature of the water after dropping the iron ball has been 60.
The heat transferred by the iron ball can be given by:
Heat (Q) = mcT
Q = heat transferred = 8.4 kJ
Q = 8400 J
m = mass = 200 g
c = specific heat = 4.2 J/g.
T = change in tempertaure = Initial temperature - final temperature
T = Final temperature - 50
8400 J = 200 g 4.2 J/g. (Final temperature - 50 )
Final temperature = 60.
The final temperature of the water after dropping the iron ball has been 60.
Answer:it’s called osmosis
Explanation:Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.
in absence of oxygen.
i have resd about in my biology textbook.
sorry i kniw this much
