Answer:
0.15
Explanation:
The partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.
What is Dalton's law?Dalton's law can be described as the total pressure of all gases exerted being equal to the sum of the partial pressures of every gas in the mixture of non-reacting gases.
The total pressure of a gas mixture of gases can mathematically be defined as :
P (total) = P₁ + P₂ + P₃ + ......
Given, the total pressure of a gas mixture = Ptotal = 1.05 atm
The fraction of carbon dioxide in the mixture = 55 % = 0.55
The fraction of nitrogen in the mixture = 31 % = 0.31
The partial pressure of carbon dioxide in the mixture can be calculated as:
P(CO₂) = 0.55× P(total)
P(CO₂) = 0.55× 1.05
P(CO₂) = 0.58 atm
Therefore, the partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.

When a company is to calculate the selling price of their products, they set up a product calculation. There are five benefits to the business when making a product calculation. Explain these five benefits.
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.
Why is blood is sometimes called "the river of life"?
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

Please help me with this chem question, I’ll mark you brainiest if it’s right. There’s multiple answers for this one.
Cant be B) or C)
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.
Calculate the mass of 488 moles of calcium carbonate, CaCO3
Help please!
Answer:

Explanation:
why would a percent yield be less than 100%? give a reason
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.

What is the purpose of adding sodium carbonate to the reaction mixture?
I
Answer: As sodium carbonate is added, bubbles of carbon dioxide form. When all the acid has been neutralised, adding sodium carbonate will no longer produce bubbles of carbon dioxide gas. The final rinsing with water should remove traces of the water soluble salt formed.

8 billion molecules of O2 gas
1. A typical home instant pot has an internal volume of 6.5 Liters. If the steam inside an instant pot with an internal pressure of 191.0 kPa and a temperature of 750.0 K was released into the atmosphere at 101.3 kPa and 298K, what volume with the steam occupy in the atmosphere?
2. Even though the pressure was reduced by nearly half in the scenario above, the volume of the gas decreased. Explain why. Support your answer with evidence and scientific reasoning.
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!
