Answer:
b. Mg (s) + 2HCl (aq) --> MgCl2 (aq) + H2
Explanation:
A subscript applies only to the element it is attached to while coefficients apply to all elements in a compound.
"a" has 1 atom of each element on the left but 2 Cl on the right.
"c" has 2 Mg, 1 H, & 1 Cl on the left but 1 Mg, 2 H, and 2 Cl on the right.
"d" has 2 atoms of each element on the left but only 1 Mg on the right.
"b" is the only answer with equal numbers of atoms on the right and left sides of the equation.
Calorimetry-the science or act of measuring changes in state variables of a body for the purpose of deriving heat transfer associated with changes of its due date.
Answer: Um pretty sure it is 22.35 m/s
1). Take your current speed in either kmph or mph.
2). Divide it by 60 to get kilometers per minute or miles per minute.
3). Divide by 60 again, getting kilometers per second or miles per second.
And der you go.
Answer:
Average atomic mass = 14.0067 amu.
Explanation:
Given data:
Abundance of 1st isotope = 99.63%
Atomic mass of 1st isotope = 14.003 amu
Abundance of 2nd isotope = 0.37%
Atomic mass of 2nd isotope = 15.000 amu
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (99.63×14.003)+(0.37×15.000) /100
Average atomic mass = 1395.119 + 5.55 / 100
Average atomic mass = 1400.67 / 100
Average atomic mass = 14.0067 amu.
