常用的補(bu)鈣(gai)營養強化(hua)劑(ji)—碳酸鈣(gai)有兩種(zhong)(zhong):一種(zhong)(zhong)是重質碳酸鈣(gai),是石灰石經過粉(fen)碎到(dao)一、石灰石制(zhi)(zhi)砂(sha)(sha)機設(she)備1、沖擊(ji)式制(zhi)(zhi)砂(sha)(sha)機它是制(zhi)(zhi)砂(sha)(sha)設(she)備中比較(jiao)常見(jian)的設(she)備答案: 安徽富邦裝飾幫您解答：石灰石的摩爾硬(ying)(ying)度(du)(du)值(zhi)是3。從風化(hua)f=2~堅固f=15,分軟,中硬(ying)(ying)和硬(ying)(ying)巖,具體看f值(zhi),及新鮮程度(du)(du)石灰石摩氏(shi)硬(ying)(ying)度(du)(du)3,加(jia)熱到(dao)攝氏(shi)800度(du)(du)以上

答案: 理(li)論都是(shi)碳酸鈣,但貝(bei)殼質地均勻,密度(du)大,所以(yi)貝(bei)殼硬更(geng)多關于(yu)硬的石(shi)(shi)(shi)灰石(shi)(shi)(shi)是(shi)哪種(zhong)的問題(ti)>>石(shi)(shi)(shi)灰石(shi)(shi)(shi)是(shi)種(zhong)用(yong)途廣泛的礦產(chan).請你合(he)理(li)利(li)用(yong)石(shi)(shi)(shi)灰石(shi)(shi)(shi)的性質判斷其用(yong)途.(A)比較堅硬、難溶于(yu)水(shui)(B)高(gao)溫下可分解(C)與稀(xi)鹽酸發生復(fu)分解反(fan)應(ying)(1)作建筑物的地基是(shi)利(li)用(yong)

據魔方格專家權威(wei)分析,試題"在天然存在的物質中,硬度的是(shi)()A.石(shi)(shi)灰(hui)石(shi)(shi)B.碳是(shi)一種(zhong)(zhong)很常(chang)見的元(yuan)素(su),它(ta)以多種(zhong)(zhong)形式廣(guang)泛存在于大(da)氣和地(di)殼(ke)之中。碳單質很早在天然存在的物質中,硬度的是(shi)( ) A.石(shi)(shi)灰(hui)石(shi)(shi) B.石(shi)(shi)墨(mo) C.金剛石(shi)(shi) D.鐵礦碳是(shi)一種(zhong)(zhong)很常(chang)見的元(yuan)素(su),它(ta)以多種(zhong)(zhong)形式廣(guang)泛存在于大(da)氣和地(di)殼(ke)之中。碳單質很早

答(da)案: 鐵(tie)礦石(shi)(shi)(shi)的(de)(de)(de)硬(ying)(ying)(ying)度大。 可用(yong)莫(mo)氏硬(ying)(ying)(ying)度來劃分。 莫(mo)氏硬(ying)(ying)(ying)度又名(ming)莫(mo)斯硬(ying)(ying)(ying)度,表示礦物(wu)硬(ying)(ying)(ying)度的(de)(de)(de)一種(zhong)標準。1812年由德(de)國(guo)礦物(wu)學家莫(mo)斯(Frederich Mohs)首先提出(chu)。用(yong)測得的(de)(de)(de)更(geng)多關于硬(ying)(ying)(ying)的(de)(de)(de)石(shi)(shi)(shi)灰(hui)石(shi)(shi)(shi)是哪種(zhong)的(de)(de)(de)問題>>答(da)案: 石(shi)(shi)(shi)灰(hui)石(shi)(shi)(shi)是生產生石(shi)(shi)(shi)灰(hui)的(de)(de)(de)主要原料(liao). 二氧化碳(CO2)能使澄清石(shi)(shi)(shi)灰(hui)水（CaOH2）變(bian)混(hun)濁(zhuo). 石(shi)(shi)(shi)灰(hui)和石(shi)(shi)(shi)灰(hui)石(shi)(shi)(shi)大量用(yong)做建筑材料(liao),也(ye)是許多工(gong)業的(de)(de)(de)重要原料(liao).石(shi)(shi)(shi)灰(hui)石(shi)(shi)(shi)可直接加(jia)工(gong)成(cheng)石(shi)(shi)(shi)料(liao)
