Answer:

properties of acid

sour taste

change the color of indicators

acids react with active metals to form salt and hydrogen gas

acids react with carbonates and hydrogen carbonates to form salt, water, and carbon dioxide gas

acids neutralize base

acids are electrolytes

properties of base

bases are slippery to the touch and have bitter taste

soluble bases change the colour of indicators

soluble bases release hydrogen ion in aqueous solution

bases neutralize acids or acidic oxides to form salt and water

aqueous solutions of bases conduct electricity

What is the molarity of a solution with 130g of CoCl2 in 1/2 liter? (can you show the steps please)

Elden [556K]

Answer:

Explanation:

M=mol/L

1. Find moles of CoCl2

mass of substance/molar mass = 130/129.833 = 1.001 mol

3. Substitute in molarity equation

M=(1.001/0.5)

M= around 2M

How many moles are 7.25 x 1023 formula units of Mgo ?

romanna [79]

Answer:

<h2>The answer is option D</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{7.25 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{7.25}{6.02} \\ = 1.2043189368...$

We have the final answer as

<h3>1.20 moles</h3>
