Answer:
Explanation:
no. of moles of butane = 5.87g / 58.124 = 0.1009mol
since O2 is excess, limiting reagent is butane
from the equation, 2 moles of butane will reacted to produce water = 10 moles
therefore, 0.1009 moles of butane produced water = (0.1009 x 5) = 0.5050 moles
Weight of H2O formed = 0.5050 x 18.015 = 9.10 grams
Answer:
It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed.

Explanation:
Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Neutralization reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.
Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
Example:
Double displacement reaction is one in which exchange of ions take place. Example:
Answer:
Electromagnetic spectrum
Explanation:
Telescopes are used by observers to monitor various electromagnetic radiation. Only one component of the visible radiation can be observed by each type of instrument. Telescopes, ultraviolet telescopes, optical celestial objects, and other types of telescopes are available.
