How many moles of cobalt (Co) atoms are there in 6.00 times 10 to the 9th power cobalt atoms?

Answers

Answer:

In $6.00 * 10^9$ of cobalt atoms there are $6.00 * 10^9$ mol Co

Explanation:

Step 1 : Identify the relationship between 1 mole Cobalt and Avogadro's number of atoms.

$1 \text{mole Cobalt } = 6.022 * 10^(23) \text{ atoms of cobalt }$

Avogadro’s number is number of units present in one mole of any substance (defined as its molecular weight in grams)

Step 2: Divide the given atoms of cobalt by the number of atoms per mol.

Given atoms of cobalt is $6.00 * 10^9$

Now by performing division

Number of moles of cobalt (Co) atoms in $6.00 * 10^9$ cobalt atoms is

= $(6.00 * 10^9)/(6.022 * 10^(23))$

= $0.996 * 10^9 * 10^(-23)$

= $0.996 * 10^(9 -23)$

= $0.996 * 10^(-14)$

Carbon burns in the presence of oxygen to give carbon dioxide. Which chemical equation describes this reaction?© A.
carbon + oxygen + carbon dioxide
OB. carbon + oxygen - carbon dioxide
C.
carbon dioxide - carbon + oxygen
O D.
carbon dioxide + carbon - oxygen

Answers

Answer:

Explanation:

when burning a chemical compound the lighter element seperates from the stronger one

Answer: D) carbon dioxide + carbon - oxygen

Explanation: In the gas phase, carbon dioxide molecules undergo significant vibrational motions and do not keep a fixed structure. However, in a Coulomb explosion imaging experiment, an instantaneous image of the molecular structure can be deduced. Such an experiment has been performed for carbon dioxide. The result of this experiment, and the conclusion of theoretical calculations based on an ab initio potential energy surface of the molecule, is that none of the molecules in the gas phase are ever exactly linear. This counter-intuitive result is trivially due to the fact that the nuclear motion volume element vanishes for linear geometries. This is so for all molecules (except diatomics!).

How do u separate salt from rock salt?

Answers

In order to separate salt from rock salt, first crush the salt rock into small pieces, put it in a container and add water. Stir until it dissolves. Pour the solution to a funnel lined with coffee filter. Heat the filtered water and the water will evaporate leaving salt behind.

Answers

aprons are used to cover your body (most people use la coats though) and goggles are used to cover your eyes.

A Safety shower should be used for more significant spills.

An MSDS (Material Safety Data Sheet) describes important safety and reactivity information about a chemical.
