Answer:
–0.16 m
Explanation:
From the question given above, the following data were obtained:
Time (t) = 0.18 s
Acceleration due to gravity (g) = –9.81 m/s²
Height (h) =?
We can obtain how far the ruler will fall by using the following equation:
H = ½gt²
H = ½ × –9.81 × 0.18²
H = ½ × –9.81 × 0.0324
H = –0.16 m
Thus, the ruler will fall –0.16 m before you will catch it.
Barium nitrate and methane (CH4) are both soluble. They both will dissolve in water, however, barium nitrate will dissociate becoming barium 2+ ions and nitrate becoming NO3 1- ions. All nitrates are soluble and dissociate. CH4 is a weak base and does dissolves but doesn't dissociate. So in solubility terms.... they are both equally soluble just one happens to dissociate into its cations and anions. Hope this helps!
Answer:
244.76
Explanation:
The weight of grams by 1.82 moles of lithium carbonate would be: 134.481438 So we need to use this equation to find mass by grams m × g = ms Where m is for moles, g for grams, and ms for mass. So now we need use this equation: 1.82 × 134.481438 = ? 1.82 × 134.481438 = 244.75621716 244.75621716, rounded-up (to the nearest-tenths place) is 244.76. So now you have it! The mass of 1.82 moles of lithium carbonate is 244.76!

A. Compound that has the highest solubility in pure water is caso4, ksp = 2. 4 x 10-5
More about CASO4:
The inorganic chemical with the formula CaSO4 and its associated hydrates are known as calcium sulphate (sometimes known as calcium sulphate). It serves as a desiccant in the form of -anhydrite (the anhydrous form).
Another hydrate is found naturally as the mineral gypsum, while one is more commonly known as plaster of Paris. It is employed widely in industries. Each form is a white solid that has a low water solubility. Water becomes permanently hard due to calcium sulphate.
CaSo4 is mostly used to produce plaster of Paris and stucco.
