Answer:
18
Explanation:
The atomic number of chlorine is 17 therefore the atom has 17 electrons, the ion however has 1 extra electron. The charge becomes negative because electrons have a negative charge. 17 + 1 = 18, therefore a chlorine ion with a charge of -1 has 18 electrons.
Explanation:
Is the loss of electrons, gains of oxygen or loss of hydrogen
What do you need help with? Can you specify?
Answer:
as the world is changing we change also
Explanation:
We must always check and recheck are a hypothesis
The amount of heat required is calculated using the below formula
Q(heat) =M(mass) xC(specific heat capacity)x delta T (change in temperature)
change in the temperature in kelvin=(35+273)- (25 +2730= 10K
c= 2.48 j/g/k
mass= 54.0 g
Q= 54.0 g x 2.48 j/g/k x 10k = 1339.2 joules is required
