Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
Explanation:
<span>29 protons and 27 electrons.
Since the element is copper, that automatically means that you have 29 protons. Any other number would be an element other than copper. The 2+ indicates that the ion has a positive charge of 2. So it is missing 2 electrons. Since a neutral atom would have 29 electrons and you're missing 2, the number of electrons will be 29 - 2 = 27
So the answer is 29 protons and 27 electrons.</span>
Answer:
0.24 L of oxygen gas will be required to produce 0.160 L of nitrogen gas.
Explanation:
From the reaction, 3 moles of oxygen react with ammonia to produce 2 moles of nitrogen gas
So, 3 moles of 02 = 2 moles of N2
Since I mole of a gas occupies 22.4dm^3 or 22,4 L of the gas
3 * 22,4L of O2 produces 2 * 22.4 L of N2
67.2 L of O2 produces 44.8 L of N2
( 67.2 * 0.160 / 44.8 ) L of O2 will produce 0.160L of N2
10.752/ 44,8 L = 0.24 L of O2 will produce 0.160 L of N2
0.24 L of oxygen gas will be required to produce 0.160 L of nitrogen gas.
