What was aryabhatta contribution to science?
he told that science is science and sciance cannot be science if sceince if science is not science and if science did not come from science the science will not be science
How many grams of H2 are needed to produce 12.58 grams of NH3?
12.01 g NH3 = 0.667 mol NH3 = 1 mol H2 = 2.0 g H2
What is the hypotonuse of a triangle with legs of length 12 cm and 14 cm?
By Pythagoras theorem ,we can say that h2=b2+p2 h2= 12 ^2 +14 ^2=340 h= sqrt (340)=18.4 cm
How does science pertain to science?
science is science!!
How science relates to science?
dour science is science obviously
What does h h H2 in science?
H is the atomic symbol for hydrogen. H2 is the chemical formula for the hydrogen molecule, which is the most common and stable form of hydrogen gas.
What is n2 in physical science?
That is the symbol for molecular nitrogen when two nitrogen atoms are bonded together. Similar to h2 for molecular hygrogen
Which has a strong bond H2 or H2 plus?
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
How many hudrogen molecule are there in 10grams of hydrogen?
1 mole H2 = 2.016g H2 = 6.022 x 1023 molecules H210g H2 x 1mol H2/2.016g H2 x 6.022 x 1023 molecules H2/1mol H2 = 3 x 1024 molecules H2 (rounded to 1 significant figure)
How many moles of hydrogen gas contained in 9.03x1023?
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
Formula hydrogen gas?
Its H2
What are some cool things to do for a science fair?
Some cool experiments like k +H2O, bringing a balloon full of h2 near a flame, etc.
What equation shows conservation of atoms?
H2 => h2
Which element is h2?
H2 is the elemental form of hydrogen.
Is H2 combustible?
Yes, H2 is extremely flammable.
What is pH of H2?
H2 is neutral. It does not affect pH.
What is the equation for hydrogen plus hydrogen?
Hydrogen is naturally H2 so when you combine two H2 molecules, you will get 2H2. It won't be H4 as it will only exist in pairs, not fours. If you are combining H + H, you will get H2 So either: H+H → H2 Or H2 + H2 → 2H2
