Answer:
Wave X
Explanation:
because the lower the frequency, the longer the wave length
<span>There
are a number of ways to express concentration of a solution. This includes
molarity and molality. Molarity is expressed as the number of moles of solute per volume of
the solution. MOlality is expressed as moles per kg solution.
5.25 mol H2SO4 / kg solution ( 1 kg / 1000 g ) ( 1.266 g / mL ) ( 1000 mL / 1L ) = 6.6 M H2SO4</span>
Answer:In order for a molecule to have polarity it must have an electronegativity difference of 0.5-1.7. There is polarity within sucrose because of oxygen-hydrogen and oxygen-carbon. Oxygen-hydrogen is polar because a electronegativity of 1.2 is created (O=3.4 H=2.2-----> 3.4-2.2=1.2); this is a polar molecule.
Explanation:
A 15.00 mL pipet. As a pipet is more accurate than a buret.
A change in the force of gravity on an object will affect its weight.
