Asynthesis reaction is shown in which a and b represent two reactants forming a compound c. a + b → c which of the following values is used in the stoichiometric calculations to determine the limiting reactant for the reaction?

a. mole ratio of a to b
b. mole ratio of b to a
c. starting amount of c in grams
d. starting amount of a in moles

Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves? their energy must be very their frequency must be very low these waves can travel without a medium they only travel through a vacuum of space

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
