Answer:

The following are the explanation of the true statement:

Explanation:

Compounds are sets of atoms which have been chemically related. So, if molecules begin to jump.
It can generate lumpy steaks as well as potatoes. In a certain number of protons and electrons were also found in atoms.
Electrons are organized into shells or activity levels, that have only certain capabilities if one is complete, electrodes have had to be placed in the next shell.

Compute 4.659×104−2.14×104. Round the answer appropriately.

antiseptic1488 [7]

The answer is 2.519 × 10^4. Use the distributive property: a × x + b × x = (a + b) × x. If a = 4.659, b = 2.14, and x = 10^4, then 4.659 × 10^4 − 2.14 × 10^4 = (4.659 - 2.14) × 10^4. Now, subtract numbers in parenthesis: 4.659 × 10^4 − 2.14 × 10^4 = (4.659 - 2.14) × 10^4 = 2.519 × 10^4.Hope this helps. Let me know if you need additional help!

An empty weighing dish has a mass of 1.0041 ± 0.0002 g. After you add dried sodium chloride to the dish, the mass is 3.2933 ± 0.

Maurinko [17]

Answer:

The correct answer to the following question will be "0.0013%".

Explanation:

The given values are:

Weight of an empty dish = 1.0041 ± 0.0002 g

Weight of dish + sodium chloride (NaCl) = 3.2933 ± 0.0002 g

Weight of NaCl = 2.2892 ± 0.0002 g

Now,

Volume of the solution = 500.00 ± 0.05 ± 0.0002

= 500.00 ± 0.0502 ml

So,

Molarity = $\frac{W \ NaCl}{M \ NaCl} \times \frac{1000}{Volumes \ of \ solution}$

On putting the values in the above formula, we get

= $\frac{(2.2892\addeq +0.0002)}{58.440}\times \frac{1050}{(500.00+0.0502)}$

= ( $3.917$ ± $0.0002$ ) × ( $2$ ± $0.0502$ )

= ( $0.7834$ ± $.00001004$ )

Now,

Absolute error = $\frac{0.00001004}{0.7834}\times 100$

= $0.0013$ %

What is the empirical formula for C8H20F4

AfilCa [17]

The given formula of $C_{8} H_{2} O F_{4}$ can be written as $C_{4} H_{10}-C_{4} H_{10}-F_{4}$

Explanation:

Empirical formula is one of the way of representing the structural arrangement of any molecule. With this formula, we can guess the nearest atom or element in a heterogeneous molecules. Mostly the empirical and molecular formula differs for organic compounds.

As in organic compounds consists of chain of carbon and hydrogen elements. So while arranging them in a relation, we should remember that carbon should contain 4 nearby atoms and hydrogen can share only one electron to its nearby atom. Thus, a carbon can have three hydrogen and one carbon as neighbouring element.

So the given formula of $C_{8} H_{2} O F_{4}$ can be written as

$C_{4} H_{10}-C_{4} H_{10}-F_{4}$
