最初の赤線で、炭素含有率が少ないほど燃やしたときにすすが多くなるってどういうことですか？ 二酸化炭素になる割合が多くなり、すすが少なくなると考えてはだめなんですか？ あと、炭素含有率を調べる式の立て方がよく分かりません。写真の赤線部分は何をしてるんでしょうか？

問6 33 正解6 実験IIより,イとウは燃焼試験の結果にほとんど差が ない。問5を考慮すると, イとウは(PE, PP)と考えら れる。PE, PP, PET, PS のうち, PS の炭素含有率 は92%で最大,PET の炭素含有率は 63%で最小である。 これよりPS の方が PET より、すすが多いと推測され る。よって, 実験IIより, エは PS, オは PET と考え られる。一?

Change May Come to Denmark's Cash By Sandra Gray, Copenhagen March 8, 2020· 1:25PM enbbots Cash may be on the way out, in Denmark, where credit card and mobile pavments have been adopted_widely and have become more popular than old-fashioned cash payments. Figures from 2019 show that last year only 16 percent of ordinary store payments were made in cash! The government is now considering a proposal to allow businesses such as restaurants, convenience stores and clothing stores to refuse cash payments) Dana Hasbrook of Copenhagen is looking forward to a_cashless_society. and savs, Having to withdraw money is inconvenient and _risky." Police officer Peter Nielson also supports the proposal. "Criminals won't be able to steal money from stores anymore, which will make my job easier." Not everyone is happy about a world without cash, however. /…This is a double-edged sword. Certainly, people's wallets will be lighter, but what happens when there's a problem with the system that processes credit card and mobile payments?” says Mary Daniels, a schoolteacher. “Also, when you use a credit card at a store, staff members can see your name. People shouldn't have to give out their personal information for the sake of convenience."
