need some help with just one question please help.What is the pH of a 9.7 x 10-5 M NaOH solution? (2 formulas)​

Answer:

translate DNA into RNA I hope it helps

Answer:

Usually, percent yield is lower than 100% because the actual yield is often less than the theoretical value. Reasons for this can include incomplete or competing reactions and loss of sample during recovery. ... This can happen when other reactions were occurring that also formed the product.

Answer:

Q.1

Given=

V1=6.5ltr

P1=191.0kPa

T1= 750.pK

P2= 101.3kpa

T2= 298K

V2=?

Combined gas law: P1V1/T1 = P2V2/T2

 Use the gas laws for pressure, volume and temperature calculations

Now,

191.0×6.5/750= 101.3×V2/298

V2 = 191.0×6.5×298/750×101.3

On solving further

V2 = 4.86 ltr!

4.86 volume with the steam occupy in the atmosphere!

Q.2

Scientific Reasoning:-

Temperature is directly to proportional to the pressure in second scenario the temperature was reduced to nearly half of the first one hence the pressure also decreased simultaneously, and we all know according to charles law The volume of a given gas sample is directly proportional to its absolute temperature so the decreasing temperature affected the amount of volume that decreased!

Answer:

Acid–base indicators are generally weak protolytes that change color in solution according to the pH. The acid–base equilibrium of a weak acid type of indicator (HI) in water can be represented as. [I] The acid, HI, and the conjugate base, I−, have different colors. The equilibrium expression for this process is.

Answer:

because water wets stuff expect for fire.

Answer:

The meaning of wet is covered or saturated with water or another liquid, showing that is a glass is covered in water it is considered wet.

Explanation:

Answer:

Option A. KCl (aq)

Option D. Mg(OH)₂(s

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

MgCl₂(aq) + KOH(aq) —>

In solution, MgCl₂(aq) and KOH(aq) will dissociate as follow:

MgCl₂(aq) —> Mg²⁺(aq) + 2Cl¯(aq)

KOH(aq) —> K⁺(aq) + OH¯(aq)

MgCl₂(aq) + KOH(aq) —>

Mg²⁺(aq) + 2Cl¯(aq) + 2K⁺(aq) + OH¯(aq) —> 2K⁺(aq) + 2Cl¯(aq) + Mg(OH)₂ (s)

MgCl₂(aq) + KOH(aq) —> 2KCl (aq) + Mg(OH)₂(s)

Thus, the products of the above reaction are: KCl(aq) and Mg(OH)₂(s)

Thus, option A and D gives the correct answer to the question.

Answer:

Cooling is at the bottom, Pressure is in the middle, and Settling is at the top

Answer: The answer is A heat and pressure

Explanation:

Answer:

Acetone

Explanation:

Chromatography has to do with the separation of substances by eluting the components of the solute using a mobile phase. The composition of the mixture to be separated decides the mixture of solvents (mobile phase) that are to be used for elution.

In this case the mixture to be separated comprises of substance A which is polar and substance B which is non polar. It is observed that the mobile phase moves B up the plate but not the polar substance, A. This means that a polar solvent such as acetone should be added to the mobile phase in order to achieve better elution of A.

Answer: Heat Q = m·c·ΔT

Explanation: Mass of 1.00 mol water m= 18.016 g. Heat capacity of water is

c= 4.19 J/( g K) and change of temperature ΔT= 100 K

Answer:

Exothermic.

Explanation:

So if the sum of the enthalpies of the reactants is greater than the products, the reaction will be exothermic.

Answer:

≅ 4.88 grams (3 sig. figs.)

Explanation:

to convert from ...

grams to moles => divide by formula wt.

moles to grams => multiply by formula wt.

this problem:

mass in grams = 488moles / 100.09g/mol = 4.875612 grams (calculator)

≅ 4.88 grams (3 sig. figs.)

Answer:

Blood is liquid and red, just like a red river. And for humans without blood there is no life because there is nothing to transport nutrients and oxygen to the body cells. Hence blood is the red river of life.

Answer:

i think its because of how the blood is one of the main reasons we are alive today. And without it we'd die

Answer:

The pricing strategy is an important element in setting up the selling price of a product.

Explanation:

The pricing strategy is an important consideration while fixing up the selling price of product manufactured. When setting up a selling price of a product, the companies set up product calculation. Businesses should decide the pricing strategy before they advertise the products to the customers.  

There are mainly 5 benefits to the businesses while doing a product calculation. They are:

--- Doing competition based pricing enables the company to compete with the rival companies product and is based on the market based study. Competition pricing is a useful tool for the retailers as well as the small businesses.

---  Doing a cost plus pricing helps the total cost of making the product and also an add up in the market in order to determine the pricing of the product.

--- Dynamic pricing :

    Dynamic pricing is a non static pricing. Dynamic pricing is an efficient method for the market based on the supply and demand.

--- Penetration pricing :

 Penetration pricing is used by the large companies which is used to capture the market share by the setting product prices at the below market level so as to gain customers.

--- Doing a research for the price skimming helps the company to set up the accurate price for the product rather than readjusting the prices of the product later on based on the demand and the supply.
