Question
Consider the following statements about White
hydrogen: 1. Recently scientists discovered large reservoir of white hydrogen in Italy. 2. White hydrogen is also referred to as “natural,” “gold” or “geologic” hydrogen. 3. It causes CO₂ emissions when used as a fuel. Which of the above statements is/are not correct?Solution
Recently, scientists looking for fossil fuels beneath the ground of northeastern France have discovered large reservoir of white hydrogen. White hydrogen is also referred to as “natural,” “gold” or “geologic” hydrogen. It causes no CO₂ emissions when used as a fuel.
What value should come in place of (?) in the given expression.
{(36)² − (28)²} ÷ 8 + 9² = ?
Simplify: 48 ÷ 4 × 2 + 5 × (7 − 3)
?% of 18% of 2600 = 234
What will come in the place of question mark (?) in the given expression?
(12.09)2 × 5.98 ÷ 26.95 = ? + 25
What will come in the place of question mark (?) in the given expression?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
(11/12) × (18/22) × (4/3) + 3 = ?2
The value of (43-3× (4×6+12/6 ×6-4×5) +4)?
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?
The value of [(3√2+2) × (3√2-2)] of 13 + 15 is:
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)`
