<span>The answer to this question would be They are different. Because a compound will have different characteristics from their element. </span>The interaction of different elements in a compound makes it so. They might have similar or opposite characteristic but it didn't always happen.

A compound is formed due to the chemical combination or chemical reaction between two or more elements. The elements forming a compound cannot be separated by physical means. The properties of the compound is different from the properties of the elements forming it.

Based on this, the answer would be:
They are different.

The molar mass of NaOH is 40.00 g/mol. If 5.20 g NaOH are dissolved in 0.500 L of solution, what is the molarity of the solution

lyudmila [28]

The molarity of the solution is 0.260 M

<u><em>calculation</em></u>

step 1: calculate the moles of NaOH

moles = mass÷ molar mas

= 5.20 g÷ 40.00 g/mol= 0.13 moles

Step 2: find the molarity of solution

molarity = moles÷volume in liters

=0.13 moles÷ 0.500 L = 0.260 M

A sample of 2.45g aluminum oxide decomposes into 1.3g of aluminum and 1.15g of oxygen. What is the percentage composition of the

Vitek1552 [10]

Answer:

% $Al = 53.1%$ %

% $O = 46.9$ %

Explanation:

If we know the grams of a chemical compound in a specific reaction, it is possible to know the percentage of each atom that composes it.

For the Aluminum Oxide in this problem, we know its total weight and the grams of each component.

therefore we can determine the percentage ratio of its components through:

For Al

% $Al = \frac{mass of Al}{mass of Aluminium oxide} . 100$ %

% $Al = \frac{1,3 g}{2,45 g} . 100$ %

% $Al = 53.1%$ %

In the same way for oxygen

% $O = \frac{mass of O}{mass of Aluminium oxide} . 100$ %

% $O = \frac{1,5 g}{2,45 g} . 100$ %

% $O = 46.9$ %

Why is it difficult to hold and keep liquids like water in your hand? Guys please help

Zanzabum

Answer:

Molecules move freely around since they don't have a definite shape. This is the reason water stays liquid and couldn't be gripped.
