Answer:
14 mol O₂
Explanation:
The reaction between CO and O₂ is the following:
CO + O₂ → CO₂
We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:
2CO + O₂ → 2CO₂
As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:
28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂
After that have been up for a while thay are metal
Answer: A hydrate is found to have the following percent composition: 48.8% MgSO4 and 51.2% water.
Explanation:
i dont know
Answer is: 4 atoms of nitrogen.
One formula unit of magnesium nitrate (Mg(NO₃)₂) has two atoms of nitrogen, so two formula units of magnesium nitrate will have four atoms of nitrogen (2·2=4).
Oxidation number of magnesium in magnesium nitrate is +2 and oxidation number of nitrate anion is -1 (2·(-1) = -2).
In rainbow, the color that has the longest wavelength is red which means option 5 is the correct choice.
Dispersion is described to be the spreading of white mild into its complete spectrum of colors, in truth we also can say a complete spectrum of wavelengths. The white mild turns into from solar and includes seven colors. On one end of the spectrum is red with the longest wavelength. Blue or violet mild has the shortest wavelength. White mild is a aggregate of all hues withinside the color spectrum. The colors of the rainbow are: Red, orange, yellow, green, blue, indigo, violet.
Therefore, option 5 is the correct choice.
