Haya Edith, twende na maswali haya ya kemia. 1. Kamilisha jedwali hapa chini kwa kuandika jina sahihi la elementi au radikali na valensi yake. Elementi / Radikali — ValensiMagnesium (Mg) — 2 Klorini (Cl) — 1 Carbonate (CO_3) — 2 Amonia (NH_4) — 1 Alumini (Al) — 3 Kumbuka: Valensi ya Alumini ni 3, si 2 kama ilivyoandikwa kwenye picha. 2. Andika fomula za kemikali zifuatazo: a) Sodium Chloride Sodium (Na) ina valensi 1. Klorini (Cl) ina valensi 1. Fomula: NaCl b) Calcium Nitrate Kalsiamu (Ca) ina valensi 2. Nitrati (NO_3) ina valensi 1. Fomula: Ca(NO₃)₂ c) Aluminium Oxide Alumini (Al) ina valensi 3. Oksijeni (O) ina valensi 2. Fomula: Al₂O₃ d) Copper(II) Sulfate Shaba(II) (Cu) ina valensi 2. Sulfati (SO_4) ina valensi 2. Fomula: CuSO₄ 3. Taja michakato mitatu muhimu ya habari za kemikali ambazo mlinganyo wa kemikali ulioandikwa na kusawazishwa hutoa. Mlinganyo wa kemikali uliosawazishwa hutoa habari zifuatazo: Vitambulisho vya vitendanishi na bidhaa: Huonyesha ni vitu gani vinavyoitikia na ni vitu gani vipya vinavyoundwa. Uwiano wa stoichiometric: Huonyesha uwiano wa moli (na hivyo uwiano wa masi) ambao vitendanishi huungana na bidhaa huundwa. Uhifadhi wa masi: Huonyesha kwamba atomi hazipotei wala kuundwa upya, maana yake jumla ya masi ya vitendanishi ni sawa na jumla ya masi ya bidhaa. 9. Elementi X ina isotopu mbili zinazopatikana kiasili. ^35X ina wingi wa asilimia 75% na ^37X ina wingi wa asilimia [asilimia inayokosekana]. Tafuta masi halisi ya atomiki (RAM) ya elementi X. Step 1: Pata wingi wa asilimia wa isotopu ya pili. Kwa kuwa kuna isotopu mbili tu, jumla ya asilimia lazima iwe 100%. Wingi wa ^37X = 100% − 75% = 25% Step 2: Tumia fomula ya kukokotoa Masi ya Atomiki Husika (RAM). RAM = (masi ya isotopu 1 × wingi wa asilimia 1) + (masi ya isotopu 2 × wingi wa asilimia 2); RAM = (35 × 0.75) + (37 × 0.25) Step 3: Fanya hesabu. RAM = 26.25 + 9.25; RAM = 35.50 Masi halisi ya atomiki (RAM) ya elementi X ni 35.50. 10. Eleza dhamana ya ioni. Dhamana ya ioni ni aina ya dhamana ya kemikali inayoundwa kati ya ioni mbili zenye chaji tofauti. Kawaida hutokea kati ya metali na isiyo-metali, ambapo elektroni huhamishwa kabisa kutoka atomi ya metali kwenda atomi ya isiyo-metali, na kusababisha kuundwa kwa kationi na anioni ambazo kisha huvutana kwa nguvu za kielektroniki.

An element X has two naturally occurring isotopes of 75% and 25% and 37x with a relative abundance of 75%. Find the exact relative atomic mass (RAM) of element X.
