Answer:

1 on each compound there

Explanation:

A balanced reaction is a reaction that has the same number of atoms in the reactants and products. If this number is not the same, we need to balance it putting some numbers as coefficients behind the compound or element that needs to be balanced, For example:

NH₃ ------> N₂ + H₂

As you can see in this reaction, we have 1 nitrogen and 3 hydrogens in the reactants, and in the side of products we have 2 of each element. This needs to be balanced. To do this we put a number as coeffcient to balance the atoms. In this case, we can put a number 2 behind the NH₃, so the number of atoms of nitrogen becomes 2:

2NH₃ ------> N₂ + H₂

But this 2, changes the number of hydrogens, we now have 6 (cause 2 * 3 = 6), so, let's balance hydrogen on the products to be 6, putting a 3:

2NH₃ ------> N₂ + 3H₂

Now, the reaction is balanced in each side of the reaction.

Applying the same principle to the reaction of this exercise we have the following:

NaCl(aq) + AgNO₃(aq) ---------> AgCl(s) + NaNO₃(aq)

As you can see, we have the same number of atoms on each side:

Na: 1;    Cl: 1;    Ag: 1;  N: 1;  O: 3

So we don't need to balance this reaction, with just putting the number 1 or none, is perfectly balanced.

Hope this helps

Density is d= m/vol. If a material has a mass of 65.5 g and a volume of 32.5 ml, it has a density of
ryzh [129]

Using the given formula, the density of the material is 2.015 g/mL

<h3>Calculating Density </h3>

From the question, we are to determine the density of the material

From the given formula

Density = Mass / Volume

And from the given information,

Mass = 65.5 g

and volume = 32.5 mL

Putting the parameters into the equation,

Density = 65.5/32.5

Density = 2.015 g/mL

Hence, the density of the material is 2.015 g/mL.

Put the following metric units in order from largest to smallest pL, mL, dL, kL
earnstyle [38]

Answer:

kL, dL, mL, pL

Explanation:

pL stands for picoliters. This is equal to 1 × 10⁻¹² (0.000000000001) liters.

mL stands for milliliters. This is equal to 1 × 10⁻³ (0.001) liters.

dL stands for deciliters. This is equal to 1 × 10⁻¹ (0.1) liters.

kL stands for kiloliters. This is equal to 1 × 10³ (1000) liters.

Let’s say you have 3 UV active spots in the crude material and co-spot TLC plate. One has the same Rf value as the starting mate
Troyanec [42]

Answer:

Answer: (1R,2S) / (1S, 2R) , (1R,2R) / (1S, 2S)  

Explanation:

Sodium borohydride reduction of benzoin will give four possible stereo isomers out of which are (1R,2S) - (1S, 2R) isomers and (1R,2R) - (1S, 2S) isomers which are known as enantiomers.

In general enantiomers show single spot in the TLC as they do not show any difference in Rf value (i.e) (1R,2S) - (1S, 2R) isomers show only one spot although they are two compounds and also (1R,2R) - (1S, 2S) isomers also show one spot. That is the reason why you are observing two spots in the TLC ( of reaction mixture) other than starting materilal.

Sometimes reactions to prices in oligopolistic markets can result in _________
STatiana [176]

Answer:

a price war

Explanation:

An Oligopoly is when a small group of two or more companies dominates a market. Oligopoly firms may consent to market collusion, and create barriers to new commerce entry. If the businesses do not, they will probably be forced to lower their prices and open the market to new and smaller companies.

It is the type of competition between the company selling the similar type of product , or rival companies who tries to reduce the price of the product strategizing in a way to apprehend the wider area of the market , is known as a price war .

In the event one of the firms forming the oligopoly decides to lower prices, a price war occurs breaking the balance of the oligopoly and destabilizing the equilibrium of demand and supply in that market.

Reduction of the price of any goods or commodity is considered to be one of the best method to increase its market share ,because as soon as the price of any good decreases , the sales automatically increases , as the consumers are always in search of some discounts and good deals .
