what happens to bases when mixed with acids?​

Answers

Answer 1

They form salt + water.

and the rxn is known as neutralisation rxn

Answer 2

Answer:

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. Acid-base reactions that do not occur in water usually also produce salts, but they may also produce complex ions.

A. Convert the 2 kg of water to liters of water.


O B. Convert the 10 g of NaCl to moles of NaCl.


C. Convert the 2 kg of water to moles of water.


O D. Convert the 10 g of NaCl to kg of NaCl.

Answers

Answer:

O B. Convert the 10 g of NaCl to moles of NaCl.

Explanation:

The formula for finding the molality is m=moles of solute/kg of solvent. The solute for this question is NaCl and the solvent is water.

(10g NaCl)(1 mol NaCl/58.44g NaCl)=0.1711 mol NaCl

58.44 is the molar mass of NaCl

m=0.1711 mol NaCl/2 kg H2O

m=0.085557837

write the importance of exothermic reactions​

Answers

Answer: An exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.  

Exothermic reactions are important to forensic sciences and particularly to fire and explosion investigation. When a chemical reaction requires heat (rather than producing it) and results in cooling down the surroundings, it is conversely called endothermic.

Example-  

Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake.

Explanation:

When fresh sage or mint is rubbed on the skin or any other surface the volatile chemicals associated with the integral structure of the plant part get evaporated in the surrounding air and the vapors can be detected by the olfactory receptors present in the nose. These receptors take the smell or fragrance stimulus and generate impulses or signals which goes to brain and brain interprets the smell or fragrance.

How many moles of Ba(OH)2 are present in 205 mL of 0.600 M Ba(OH)2?

Answers

Answer:

Explanation:

0.180 moles of Ba(OH)2 are present.

Answer:

[tex]\boxed {\boxed {\sf 0.123 \ mol \ Ba(OH)_2}}[/tex]

Explanation:

Molarity is a measure of concentration in moles per liter. It is calculated using the following formula:

[tex]molarity= \frac{moles \ of \ solute}{liters \ of \ solution}[/tex]

The molarity of the solution is 0.600 M Ba(OH)₂. 1 molar (M) is also equal to 1 mole per liter, so the molarity is 0.600 moles of Ba(OH)₂ per liter.

The volume of the solution is 205 milliliters, however, we need to convert the volume to liters. Remember that 1 liter contains 1000 milliliters.

[tex]\frac { 1 \ L}{1000 \ mL}[/tex][tex]205 \ mL * \frac { 1 \ L}{1000 \ mL} = \frac {205}{1000} \ L = 0.205 \ L[/tex]

Now we know the molarity and volume, but the moles are still unknown.

molarity = 0.600 mol Ba(OH)₂/ L moles of solute = x liters of solution = 0.205 L

Substitute these values into the formula.

[tex]0.600 \ mol \ Ba(OH)_2 /L = \frac{x}{0.205 \ L}[/tex]

We are solving for x or the moles of solute, so we must isolate the variable. It is being divided by 0.205 liters. The inverse of division is multiplication. Multiply both sides by 0.205 L.

[tex]0.205 \ L *0.600 \ mol \ Ba(OH)_2 /L = \frac{x}{0.205 \ L} * 0.205 \ L[/tex]

[tex]0.205 \ L *0.600 \ mol \ Ba(OH)_2 /L =x[/tex]

The units of liters cancel.

[tex]0.205 *0.600 \ mol \ Ba(OH)_2 =x[/tex]

[tex]0.123 \ mol \ Ba (OH)_2 = x[/tex]

The original measurements had at least 3 significant figures. Our answer currently has 3 sig figs, so we don't need to round.
