Answer:

294mL

Explanation:

We can use this equation to find the unknown volume:

P_1V_1=P_2V_2

To solve, plug in the values we have and solve for the unknown value:

(1.10atm)(507mL)=(1.90atm)V_2\\\frac{(1.10atm)(507mL)}{1.90atm} =V_2\\V_2=293.53mL

Rounding to three significant figures gives you the value of 294mL

Explain how our body systems work together to get oxygen into and around our body.
aleksandrvk [35]

Answer:  (1) Inhales (breathes in) Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood. (1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.

What volume of water is produced when 38.5 g of ethanol reacts with oxygen at 500°C at 1.75 atm?
tensa zangetsu [6.8K]

Answer:

90.99 or 91.0

Explanation:

Using the balanced equation, you convert 38.5g of ethanol to moles of water. From there, you plug the values into the Ideal Gas Equation: PV=nRT.

What pressure will be exerted by 25 g of CO2 at temperature of 25°C and a volume of .50 L?
Grace [21]

Answer:

P = 27.9 atm

Explanation:

Given data:

Mass of CO₂ = 25 g

Temperature = 25°C (25+273.15 K = 298.15 K)

Volume of gas = 0.50 L

Pressure of gas = ?

Solution:

Firs of all we will calculate the number of moles of gas,

Number of moles = mass/molar mass

Number of moles = 25 g/ 44 g/mol

Number of moles = 0.57 mol

Pressure of gas :

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

P × 0.50 L = 0.57 mol × 0.0821 atm.L/ mol.K  × 298.15 K

P = 13.95 atm.L/ 0.50 L

P = 27.9 atm

How can one tell how much of each reactant will be used in a reaction?
Ostrovityanka [42]
To Tell how much of each reactant will be used in a reaction, we need to find which reactant is the Limiting Reagent.
All the reactants will be consumed in equal amount as that of L.R.
