13. In the reaction: A + B = C, if 4.2 grams of A react to make 6.8 grams of C, then how many grams of B were reacted? Hint: Mass, like charge and energy, is conserved in all reactions. pls i need quick help

Hit me with brainlist pls

Explanation:

A equals 6.8 and C is the final answer of the equation so you would subtract the answer from a which gives you 2.6 grams

answer: they produce more slow than unicellular organisms.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
