Some characteristics of Ionic compounds by Mimiwhatsup: brittle, high melting point, conducts electricity when molten or dissolved in water.
It protects the alloy against rusting.
Stainless steels contain more than 10% chromium by mass, but almost no carbon. Stainless steels are durable because chromium forms an oxide that protects the steel from rusting. But stainless steel is more brittle than steels that contain more carbon.
Answer is: 5,9.
Effusion is leakage of gas
through a small hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. R<span>elative rates of effusion is related to the molecular mass.
</span>M(O₂) = 32g/mol.
M(CO₂) = 44g/mol.
t₁ = 5s.
t₂ = ?
t₂/t₁ = √(M(CO₂)/M(O₂)).
t₂ = 1,17·5s = 5,9s.
Answer: The Oxygen will have a partial negative charge, and the hydrogen will have a partial positive charge.
Explanation:
Electronegativity is the tendency of an atom to attract a pair of electrons when forming a chemical bond. The more electronegative atom will attract the electrons more, and will have a partial negative charge, because the electrons are negatively charged. The less electronegative atom will have the electrons the other atom attracted further away from it, so it will have a partial positive charge.
Oxygen is more electronegative than hydrogen. Oxygen has a nuclear charge of 16 protons (positively charged), whereas hydrogen only has 1. As a result, the pull these 16 protons produce on the electrons will be stronger than the pull only 1 proton produces, and the electrons will be closer to the Oxygen atom.
The reactants of the reaction will be solid gold (III) sulfide and hydrogen gas, while the products will be pure solid gold and hydrogen sulfide gas.
<h3>Chemical reactions</h3>
Reactants react together during reactions to arrive at products.
In this case, solid gold (III) sulfide and hydrogen gas react according to the following equation:
Reactants = solid gold (III) sulfide, hydrogen gas
Products: pure solid gold, hydrogen sulfide gas
