Answer:
See explanation
Explanation:
Molar mass of N2H4CO = 60 g/mol
Given that the relative atomic mass mass of each element is known, We discover that;
Percentage by mass of nitrogen = 28/60 * 100 = 46 .7%
percentage by mass of hydrogen = 4/60 * 100 = 6 67%
Percentage by mass of carbon = 12/60 * 100 = 20%
Percentage by mass of oxygen = 16/60 * 26.67%
They changed over time by finding the right ingredients such as iron, metal, or steel to forge different creations. They took so slowly because no one was discovered the things to make stone tools.
Personal control beliefs, also referred to as locus of control and personal mastery beliefs, reflect individuals' beliefs regarding the extent to which they are able to control or influence outcomes.
