N2O is compound becoz it has more than one type of atoms.
<span>Air is homogeneous mixture becoz it has different gases which are does not bonded to each other</span>
Explanation:
NaCl, HCl, NaOH, KCl, CH3COOH
Answer: the top one is 5.3 s and the bottom one is tenths of seconds
Explanation:
7 moles of oxygen are in the sample.
According to the chemical formula, each mole of nickel tetracarbonyl contains 4 moles of C atoms. Simply convert it into a fraction by putting the original solution in the denominator and the diluted solution in the numerator if you need to determine the concentration ratio between two solutions. The V/n ratio for each gas must be the same if the two gases are at the same temperature and pressure. The volume ratio of two gases at the same temperature and pressure is equal to their molar ratio. The mole ratio of C to O is 1 : 1
