All alkail metals react with halogens vigorously to produce salt. The alkali metal would loose an electron to form and ion with the halogen
No I can’t
EXAMPLE took the test k12
C is the answer because he wants to know if less force is needed to pull on a slippery surface which reduces friction
Assuming the question is asking for percent composition by mass,
The molar mass of sodium bicarbonate is:
22.990 + 1.008 + 12.011 + 3*15.999 = 84.006 g/mol
The molar mass of 3 oxygen atoms is:
3*15.999 = 47.997 g/mol
The percentage composition by mass is:
47.997/84.006 * 100% = 57.1% (3 s.f.)
