Answer:

see explanation

Explanation:

Write the balanced COMPLETE ionic equation for the reaction when Na₂CO₃ and AgNO₃ are mixed in aqueous solution. If no reaction occurs, simply write only NR.

Ag (+1) + NO3(-1) + 2 Na(+1) + Co3 (-2)--> Ag2CO3 (s) + 2 Na (+1) + 2NO3(-1)

What's the balanced equation for cellular respiration?
Alik [6]
<span>Correct answer is:

C_{6}H_{12}O_6+6O_{2}\Rightarrow 6CO_{2}+6H_{2}O+energy

But how to get there?

Let's start with simple explanation of what exactly is cellular respiration. 

Cellular respiration is a multistage biochemical oxidation process of organic substances when prime product is energy (ATP - adenosine triphosphate) and other are released waste products. Cellular respiration takes place even if other metabolic processes are stopped, but cellular respiration may differ in particular organism groups.Some reactions during whole process of cellular respiration are similar in all types of living organisms.

Cellular respiration is prime indication of declining living processes.Only viruses which are on the edge of living organism and chemical particle are not performing cellular respiration.But to the point :P

In cellular respiration all substrates which are in the cell might be organic, but mostly we are using sugar oxidation - glucose in the presence of oxygen. Chemical formula of sugar looks like this:

C_{6}H_{12}O_6

Oxygen is just

O_2

so for now we have just part of the equation:

C_{6}H_{12}O_6+O_{2}\Rightarrow

But what would be on the right hand side?

It's quite simple, remember equation of full combustion? If we want to burn something we need oxygen like in the equation, so the product of this equation would be carbon dioxide, water and of course energy (ATP).Carbon dioxide formula looks like this:

CO_{2}

As a reminder water formula:

H_{2}O

Full formula would look like that:

C_{6}H_{12}O_6+O_{2}\Rightarrow\ CO_{2}+H_{2}O+energy

But still as you see this equation is unbalanced, after balancing it would like that:

C_{6}H_{12}O_6+6O_{2}\Rightarrow 6CO_{2}+6H_{2}O+energy

At the end I would like to explain one more thing. Energy which has been released during this process is part of high-energy connection which might be used to perform chemical reactions in the cell or to move organism for example in muscles. We need to remember that production of ATP is not happening with 100% efficiency and part of this energy is released as heat.</span>

A dental assistant is preparing to use a chemical that has a number 2 in a blue triangle on the chemical label. Before using the
Effectus [21]

Labels must clearly identify the chemical and include information on its hazards, plus instructions and information on its safe storage, handling, use, and disposal.

What does the information on the chemical label indicate?

The chemical label indicates the following information.

Product Identifier: The method used to identify the chemical (in the ingredient disclosure). On the label, include the complete chemical name or number that is used for the hazardous product. Both the label and SDS must have the same information. Abbreviations for chemicals are not accepted.

Signal Words: Assigned to a GHS hazard class and category, "Danger" or "Warning" are used to underline hazards and show the relative level of severity of the hazard.

Danger Statements: Typical expressions that are associated with a hazard class and category and that define the hazard's characteristics. On a label, there must be mention of every danger that applies.

Precautionary Statements: A term that describes actions that should be performed to reduce or eliminate negative effects brought on by exposure to or inappropriate storage of a substance.

Symbols (hazard pictograms): Convey information about environmental, physical, and health hazards that are categorized and allocated to a GHS hazard class.

How many moles are there in 2.30 x 1024 atoms of silver?
Sunny_sXe [5.5K]

Answer:

Step 1 should be convert atoms to moles (n). Step 2 should be convert moles (n) to mass (m).

Step 1

Use dimensional analysis to convert the number of atoms to moles.

1 mole atoms = 6.022 × 10²³ atoms

n(Ag) = 2.3 × 10²⁴ Ag atoms × (1 mol Ag/6.022 × 10²³ Ag atoms) = 3.8193 mol Ag

Step 2

Convert the moles of Ag to mass.

mass (m) = moles (n) × molar mass (M)

n(Ag) = 3.8193 mol Ag

M(Ag) = atomic weight on the periodic table in g/mol = 107.868 g Ag/mol Ag

m(Ag) = 3.8193 mol × 107.868 g/mol = 412 g Ag = 410 g Ag rounded to two significant figures

The mass of 2.3 × 10²⁴ Ag atoms is approximately 410 g.
