chem 既問題
個ar sir 冇教過就叫我地做project(好死唔死仲計考試分...)仲要起返學第一日交
其中一條question完全不能理解
大家幫幫手吧-v-
What are the compositions of the following alloys?
全條都係問題來的~"~ brass = 銅+鋅 copper=銅
steel and iron =鐵+鉻+鎳+鋁
solder and tin = 鉛+錫
coinage metals and nickel = 唔鬼記得
carat gold and pure gold = 金
類似咁掛... nickel =鎳
coinage metals=硬幣金屬<----呢個上裝分開查字典 兩個英文解釋+埋:49; brass = 銅+鋅 copper=銅
steel and iron =鐵+鋼
solder and tin = 銲+錫
coinage metals and nickel = 鎳
carat gold and pure gold = 前面果個唔知咩金 後面一定係純金= =
coinage metals即係硬幣金屬 有好多金屬都得嫁bo= =你上百度慢慢搵啦- - 回復 4# 339122
主要成份都係呢幾種,當然會有其他,不過果d唔係中學讀- -
唔同公司整既又可以唔同,無可能有100%岩既答案,所以係答大約既就ok
你所講既 硬幣金屬 呢..我讀果陣就記得本書寫左4-5種元素出黎 理科:37;唔係問理科就係英文,都係我最討厭的科目:84;希望大部分都係高人:61;
如果有人問下文科都幾好:60; 本帖最後由 andyyeung0927 於 2010-2-18 11:04 PM 編輯

參考資料唔嫌多既~ 其實我睇唔明你地寫乜~"~

carat gold and pure gold = 金
-------------------------分隔線-----------------------------
