"in a test tube was add a piece of zn and 2 ml of hcl (.1m). this reaction produced zncl2 and hydrogen gas. this reactions is a:
a. combustion
b. synthesis reaction
c. double replacement reaction
d. single replacement reaction"

When the following equation is balanced using the smallest possible integers, what is the coefficent of oxygen gas? c7h16o(g) + o2(g) → co2(g) + h2o(g) -1 -5 -8 -16 -21

How to convert a density of 0.791g/cm3 to lb/ft3

Ill give brainiestif one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? if each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? how many neutrons in total were produced by the two fission events described?
