Answer:
Mass of chemical = 50 gram
Explanation:
Given:
Volume of chemical = 5 ml
Density of chemical = 10 g/mL
Find:
Mass of chemical
Computation:
Mass of chemical = Density of chemical × Volume of chemical
Mass of chemical = 10 × 5
Mass of chemical = 50 gram
Answer:
Explained below:
Explanation:
The global temperature means the fluctuations in the temperature of the atmosphere and the oceans (existing in the earth surface).
Is the Earth’s global temperature is maintained or not depends on how much sunlight hits Earth versus and how much is returned, it also depends on the atmospheric level of carbon dioxide which prevents the earth from extreme cooling during the night.
2Fe+ 6HBr ---> 2FeBr3 +3H2
Fe is a reducing agent is what that is true in equation above This is because it oxidation state move from zero to positive three.Reducing agent is an element or compound that loses or donate an electron to another chemical species in a redox chemical reaction. Fe is oxidized since it loses electron in the redox reaction
Answer:
nitrogen monoxide: NO
nitrogen dioxide: NO₂
Explanation:
Nitrogen monoxide is composed by 1 atom of O (prefix "mono-") and 1 atom of N. Nitrogen dioxide is composed by 2 atoms of O (prefix "di-") and 1 atom of N. As the oxigen atom in oxides has the valency -2 (it shares 2 electrons), the nitrogen has valency +2 in NO and +4 in NO₂.
