Вище наведені рівняння реакцій містять кілька некоректних формул речовин. Нижче наведено правильні рівняння реакцій для коректних формул:

Mg + H₂SO₄ = MgSO₄ + H₂

Hg + H₂SO₄ = HgSO₄ + H₂ (не відбувається при нормальних умовах)

MgO + HCl = MgCl₂ + H₂O

Mg + H₃PO₄ = Mg₃(PO₄)₂ + 3H₂ (Mg замість H₂PO₂)

Al + 2H₃PO₄ = Al(H₂PO₄)₃ + 3H₂ (Al замість H₂PO₂)

Fe + 6HCl = 2FeCl₃ + 3H₂

Al₂O₃ + 6HCl = 2AlCl₃ + 3H₂O (Al₂O₃ замість Al₂O₂)

Cu + H₂SO₄ = CuSO₄ + H₂ (для розчину води і дилатованого H₂SO₄)

Al + 3H₂SO₄ = Al₂(SO₄)₃ + 3H₂

Ca + 2HCl = CaCl₂ + H₂

Ag + HCl - не реагує (срібло не реагує з хлоридною кислотою при нормальних умовах)

2Fe + 6HCl = 2FeCl₃ + 3H₂ (Fe₂O₂ не існує; використовуємо Fe замість цього)

HgO + H₂SO₄ = HgSO₄ + H₂O

CaO + 2H₃PO₄ = Ca(H₂PO₄)₂ + H₂O (HPO замість H₃PO₄)

Fe(OH)₂ + H₂SO₄ = FeSO₄ + 2H₂O

CuO + H₂SO₄ = CuSO₄ + H₂O

помогите пожалуйста нужно поставить в нужной форме. Urkuya Salieva (1) was born (be born) in 1910 in a village in the Nookat region. Her father (2) (be) an ordinary farmer and he (3) (educate) his daughter in the century-old traditions and customs. From an early age, Urkuya (4) (demonstrate) leadership qualities. By the age of eighteen, she (5) (already/become) a secretary of the Komsomol, which was a political youth organization in the Soviet Union. At that time, women (6) (not/have) any rights; however, Urkuya (prove) that women should have a say. She (fight) for freedom and (9) (believe) in a (8) better tomorrow for all the working people of Kyrgyzstan. In 1928, Urkuya's fellow villagers (10) (elect) her as chairperson of the collective farm Kyzyl-Asker that she (11) (organize). This was incredible, because a woman (12) (never/be) the head of a collective farm before! Between 1928 and 1934, Urkuya (13) and the government. She (14) who (15) (work) for the Communist party (respect) by people. (call) her "aksakal woman". Unfortunately, Urkuya's ARCUS dream of making ordinary people happy (not/come true). She and her by Basmachi fighters. PUBLISHING (kill) in 1934 Nowadays, Urkya Salieva is a symbol of the movement for women's rights. Because of her contributions, the women's march for equality and solidarity ends every year near the monument in Fighters of the Revolution Square. It is also a place for remembering tragedies in which women died or suffered.​
