Gerald's science teacher mixed room temperature samples of hydrochloric acid and sodium hydroxide in a large beaker. The solutio

n still looked clear like water, but when the students carefully touched the beaker one at a time, it felt warm to the touch.
Why did the beaker most likely feel warm?

 <span>HCl is a strong acid and NaOH is a strong base, so mixing them together will produce a lot of heat. The products are salt or Sodium chloride (NaCl) and water (H2O). Since one is an acid and one is a base they will neutralize each other. I hope this helps</span>

Answer:

The beaker feels warm because is an exothermic reaction

Explanation:

An exothermic reaction is one that releases energy, in this case, through heat. Then, when HCl, a strong acid, and NaOH, a strong base, are mixed together it is produced a salt and water with a release of energy. The reaction is expressed as:

HCl + NaOH ------> NaCl + HCl + Energy

This happens because the energy of the products is lower than the energy of the reactants.

It is composed of an alloy that is 90% Platinum and 10% Iridium; having a density of 21.186 g/cm3. What is the volume of the Sta
oksian1 [2.3K]
The alloy has a density of 21.186g/cc. So for a kilogram or 1000 grams/21.186 g/cc= 45.7 cc. So the answer is 45.7 cc of the allow to make up a kilogram which shows that the density of the allow can be used to calculate the volume of a larger mass ie the kilogram.

How many moles of LiOH are required to make 4.2 liters of a 0.98 M
ASHA 777 [7]

Answer:

4.12 mol  

Explanation:

Given data:

Moles of LiOH  required = ?

Volume of solution = 4.2 L

Molarity of solution = 0.98 M

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

we will calculate the moles from above given formula.

0.98 M = number of moles / 4.2 L

0.98 M × 4.2 L = number of moles

Number of moles = 0.98 M × 4.2 L

Number of moles = 4.12 mol     (M = mol/L)

How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?
mash [69]

Answer:

0.80 Moles of Hydrochloric Acid would be required to produce 0.40 Moles of hydrogen gas due to the equation ratios

Explanation:

How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?

Hydrochloric acid = HCl

Hydrogen gas = H2

H = 1+

Cl = 1-

HCL = H2 + Cl2

2HCl = H2 + Cl2

2:1:1

0.80 = 0.40 + 0.40
