Which of the following statement is/are true?
I. Metal oxides are acidic in nature
II. Non-metallic oxides are basic in nature
Metal oxides are basic in nature. Because they react with weak acids to produce salt and water, metallic oxides are basic in nature. Oxides of non – metals are acidic.
`sqrt(7744)` - `sqrt(4761)` + `sqrt(8281)` + `sqrt(5625)` + ? = 1856
675 ÷ 15 + 225 – 18 × 6 = ?
[4(2/3) + 5(1/6)] × 45% of 240 = ?
96% of 4500 – 34% of 650 = ?
432 ÷ ? × 2552 ÷ 44 = 2088
√1369 + √1024 + √841 =(?)2 − 46
(72× 52+ 1555 )/(79+60) = 2000 ÷ ?
25% of 160 × 18 = ? – 24
4387897 – 3286871 – 51926 = ?
120% of 400 + ?% of 520 = 1000
