The picture depicts the data of the chemical, explaining that as the temperature rises, the chemical reaction rate would increase as well.
Answer:
when the carbon dioxide infiltrates the gas into molecules
Explanation:
Answer:
Mg(OH)2(s) + 2HCl(aq) → 2H2O(l) + MgCl2(aq)
Explanation:
A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pairExample: In H-H each H atom has an electronegativity value of 2.1, therefore the covalent bond between them is considered nonpolar. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
Density = mass / volume
= 69g / 23 ml
= 3 g / ml.
Thus, the density of the sample is 3 grams per ml or 3g/ ml
