LiOH+HBr---> LiBr +h20 If you start with 10.0 grams of lithium hydroxide, how many grams of lithium bromide will be produced?
kicyunya [14]
<span>LiOH+HBr---> LiBr +h20. Moles of LiOH = 10/24 = 0.41moles. According to stoichiometry, moles of LiOH = moles of LiBr = 0.41moles. Therefore mass of LiBr =moles of LiBr x molecular weight of LiBr = o.41 x 87 = 35.67g. Hope it helps </span>

a difference in density between gases creates buoyancy, which is the ability of an object to float. At 0 degrees celsius, helium
GaryK [48]

Answer: for an object or gas or liquid to float in another there must be a difference in density

Explanation:

Helium has a density of 0.18 kg/m³ and air has a density of 1.29 kg/m^³. If a balloon is filled with helium it will float in air due to density differences

Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces

Zinc reacts with aqueous sulfuric acid to form hydrogen gas: zn(s) h2so4(aq) ? znso4(aq) h2(g) in an experiment, 201 ml of wet h
WINSTONCH [101]
The products of reaction are ZnSO4 and H2. Since ZnSO4 is in aqueous form (aq), therefore only H2 and water vapor contributes to the overall total pressure in the system.
Total Pressure = 764 torr = H2 partial pressure + Water partial pressure
Since Water partial pressure is 26.74 torr so,
H2 partial pressure = 737.26 torr = 0.97 atm

An order is given to administer 57 g of lactulose syrup, often used for treating complications of liver disease. The suspension
Angelina_Jolie [31]

Answer : The volume given to the patient should be, 85.5 mL

Explanation :

As we are given that the suspension contains 10g/15mL.

Now we have to determine the volume should be given to the patient.

As, 10 grams of lactulose syrup needed 15 mL volume of solution

So, 57 grams of lactulose syrup needed \frac{57g}{10g}\times 15mL=85.5mL volume of solution

Thus, the volume given to the patient should be, 85.5 mL
