The third question requires you to solve for the weight of sodium (Na) and weight of Chloride (Cl) from the calculated moles of each element Na, and Cl.
So, you need to multiply the calculated moles of Na with its molar mass (23 g/ mol) to get the answer for Na. And multiply the calculated moles of Cl with its molar mass (35.45 g/mol) to get the answer for Cl.
The objects that are rubbed together will create charges among themselves due to friction.
(1) The balloon rubbed with a wool cloth will be charged.
(2) If she comb near a small, uncharged object nothing will change.
(3) This is a scientific investigation because it does not involved a step by step process to answer a scientific query.
Answer:
I think this is the answer M=F/AM=4N/8m/s/sM=0.5kg.
Explanation:
I hope this helped!!
C-C is a nonpolar covalent bond since the two atoms are the same and both non-metals. we are left with the polar covalent bonds and to determine the most polar one, we identify the electronegative difference of the two elements. In this case, the largest <span> electronegative difference is of C-F. </span>
