Answer 1

same found composition is called .. 0 A substance that have the and properties wherever Chemical electro- ③ Light is not a chemical. It is an magnetic readiation. ③ Numbere of orange gumdrops = 16 Numbеч от Чllot ump = 8 Number of black gumdrops = 16. Total number of gumdrops = 40 % of yellow gumdrops = X100% - 2007 % of black gumdrops 46x100. -40% 4 Given, ari = C2 V2 Thus, we can expecess Va as I C2 ② Geven, P, VI = P2 V2 Thus, we can express & as V = Plov. P2
