Answer:
bends and slides under one another
Explanation:
"Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle."
Answer:
20.2g (3 s.f.)
Explanation:
Please see attached picture for full solution.
Well in everything we have protons and electrons, eg. In static electrisity in a balloon when you rub the balloon on a material like your hair all the protons come off and into your hair which makes your hair go upright and funny and the ballon is desperate to get back the protons so it sticks to surfaces to gain there protons to ballance out the electrons it allready has for it to be nuteral again. Because its important for everything that can be to be nuteral
Mass of chlorine =
(given)
Molar mass of chlorine =
Now, number of moles is defined as the ratio of given mass in gram to the molar mass of the compound.
Number of moles = 
Number of moles of chlorine =
= 
Now, according to significant figure rules, the least number of significant figure in the question identifies the number of significant figures in the solution.
Thus, in question, both digit have four significant figures, therefore, the answer must be in four significant figures.
Hence, number of moles of chlorine = 
Answer:-
27.38%
Explanation:-
Molecular weight of sodium hydrogen carbonate NaHCO3
= 23 x 1 + 1 x 1 + 12 x 1 + 16 x 3
= 84 gram
Total sodium Na present in NaHCO3 = 23 x 1 = 23 gram
Percentage of sodium present=
Total sodium x 100/ (Total molecular weight)
= 23 x 100 / 84
= 27.38 %
