Answer: Peanut butter is the bomb.
Explanation: It's good. If you wanna die, you can drown in it.
Pair of LiI and Ca(NO3)2 is soluble in water.
Here LiI stands for lithium iodide and Ca(NO3)2 stands for Calcium Nitrate.
Water's polarity, which is the unequal sharing of electrons among its atoms, is what allows it to be such a great solvent. Typically, water is held together through this polarity of partial positive and negative charges. Positive is attracted to negative, making a cohesive structure. When polar compounds or ions are added to water, they break up into smaller components, or dissolve, to become part of the solution. The water's partial charges attract different parts of the compound, making them soluble in water.
Polar Molecules
Similar to ions, polar molecules are able to dissolve in water. Like water, polar molecules have partial positive and negative charges. The attraction between opposite partial charges helps polar molecules dissolve in water.
Water doesn't have a full positive or negative charge; instead, it possesses a partial positive and partial negative charge. This is because oxygen is a lot more electronegative than hydrogen. This means that oxygen draws more electrons to it than the hydrogen does. Since more electrons are moving towards the oxygen, it has a slightly higher negative charge than water's hydrogen atoms.
Let's look at another simple example: a carbon-fluorine bond. Since fluorine is more electronegative than carbon, it draws more electrons over to it, making it partially negative.

The balanced equation for the reaction is
HCl + NaOH = H2O + NaCl
So for every mole of NaOH used, one mole of HCl is neutralized. So let's determine how many moles of NaOH we used. That will simply be the volume (in liters) of solution multiplied by the molarity. So
0.0493 L * 0.151 mol/L = 0.0074443 mol
Because of that 1:1 ratio, we now know that 0.0074443 moles of HCl was in the sample. Since molarity is moles per liter, a little division will give us the molarity of the HCl solution. So
0.0074443 mol / 0.025 L = 0.297772 mol/M = 0.297772 M
Rounding to 3 significant figures gives 0.298 M.</span>
Answer:
Explanation:
Since it first order, we use order rate equation
In ( ) = -kt where A1 is the final quality = 0.8 (80%), A0 is the initial quality = 1 ( 100%)
also, t half life = where k is rate constant
k = = 0.0154
In ( ) = - 0.0154 t
-0.223 / -0.0154 = t
t = 14.49 approx 14.5 days from the date the yogurt was packaged
Explanation:
Compound A:
Mass of sulphur = 0.603g
Mass of Palladium = 0.397g
0.603g of sulphur combine with 0.397g of Palladium.
Therefore, 1g of sulphur will combine with = 0.397 / 0.603 = 0.658g of Palladium
Compound B:
Mass of sulphur = 0.301g
Mass of Palladium = 0.699
0.301g of sulphur combine with 0.699g of Palladium. Therefore, 1g of sulphur will combine with
= 0.699 / 0.301 = 2.322g of Palladium
Compound C:
Mass of sulphur = 0.151g
Mass of Palladium = 0.849g
0. 151g of sulphur combine with 0.849g of Palladium,
Therefore 1g of sulphur will combine with = 0.849/ 0.151 = 5.623g of Palladium
Therefore, the masses of Palladium which combine with a mixed mass (1g) of sulphur are in ratio
0.658 : 2.322 : 5.623 i.e 1: 4 : 9 which is a simple ratio
