Answer:
there
Explanation:
organic food is farmed and manufactured per the guidelines put forth by the Department of Agriculture. Organic food is typically pesticide-free, GMO-free, and sustainably farmed.
Non-GMO food, or non-genetically modified food, has not been altered or engineered in any way. Non-GMO food doesn’t necessarily adhere to the same guidelines that organic food does.
GMO food has been genetically modified in some form, usually in a laboratory.
Answer: Yes, your answer is correct.
Answer: 5.74×10^8 stacks
Explanation:
The U.S. quarter has a mass of 5.67 g and is approximately 1.55 mm thick.
1 stack would contain $2.83x 10^4
No. of stacks to pay off debt=
$16,213,166,914,811/2.83 ×10^4
= 5.74 × 10^8 stacks
Answer:
NaCl in water; ion-dipole interaction
Explanation:
Sodium chloride is an ionic solid. Ionic solids dissolve in water due to ion dipole interaction. Ionic solids are composed of an ion pair which are strongly bound by electrostatic interaction between the oppositely charged ions in the solid state.
When an ionic substance is dissolved in water, the positive ion interacts with the negative end of the dipole in water while the negative ion interacts with the positive end of the dipole in water. Hence the ions are pulled apart by this ion-dipole interaction and the crystal structure of the solid collapses as the ionic solid dissolves in water.
Sodium chloride is an ionic solid. Interaction between the sodium ion and the negative end of the dipole in water as well as chloride ion and the positive end of the dipole in water leads to the dissolution of sodium chloride solid in water. This is the strongest solute-solvent interaction in the list.
Answer:
Mass = 2.65 g
Explanation:
Given data:
Mass of sodium carbonate = ?
Mass of water = 0.125 g
Molality = 0.200 m
Solution:
Formula:
Molality = number of moles of solute / mass of solvent in Kg
by putting values,
0.200 m = Number of moles of solute / 0.125 kg
Number of moles = 0.200 m × 0.125 kg
Number of moles = 0.025 mol
Mass of sodium carbonate:
Mass = number of moles × molar mass
Mass = 0.025 mol × 106 g/mol
Mass = 2.65 g
