Answer: Your teacher is correct, although yes not every element has a charge of 0.
Explanation:
Atoms are electrically neutral because they contain equal quantities of positively charged protons and negatively charged electrons. Electrons and protons have equal but opposite charges, so the result is no net charge.
Answer:
A. Right side since CO2 has has more entropy than solid CO2
B. Right side since gaseous CO2 is present on right side
C. Left side since more no of gaseous molecules om left side
D. Right side since on heating of water at 52C starts boiling hence more entropy for vapour.
Explanation:
Generally entropy is the measurement of randomness and follows the order gas>liquid>solid

Explanation:
Given parameters:
Force applied to Jack = 120N
Force produced by Jack = 2000N
Unknown:
Mechanical advantage of jack = ?
Solution:
Mechanical advantage is the ratio of force produced by the device and the force applied on it.
It is used to access the performance of a machine.
M.A = \frac{force output}{force input}
Now input the parameters;
M.A = 
M.A = 16.7
