BLOOD HELPS YOUR BODY TO STAY AT TEMPERATURE OF ABOUT _____C. *

Chemistry
1 answer:
Paladinen [302]3 years ago
7 0

Answer:The average normal body temperature is most often said to be 98.6° F (37° C). ... One small study even suggested that in healthy older patients, body temperature ranged from 94° F to 99.6° F, with an average of 97.7° F. Several factors can lead to a lower body temperature in older people

Explanation:so the answer would be 37

A gas has a volume of 4 liters at 50 oC. What will its volume be (in liters) at 100oC
san4es73 [151]

Answer:

The volume of the gas at 100°C is 4.6189 liters.

Explanation:

For this problem we are going to use Charles' law. Charles' law states that the volume is directly proportional to temperature given that the pressure is constant. In order to use the equation, the unit of temperature should be in Kelvin.

The working equation is:

=

where V1 and T1 are the initial volume and temperature while V2 and T2 are the final conditions.

Let us convert first the temperatures before solving for the final volume.

To convert Celsius to Kelvin just add 273.15 to temperature in Celsius.

50°C + 273.15 = 323.15 K

100°C + 273.15 = 373.15 K

Solving for the final volume:

V₂ =

V₂ =

V₂ = 4.6189 L

Therefore the final volume of the gas at 100°C is 4.6189 L.

An excess of mg(s) is added to 100.ml of 0.400 m hcl. at 0c and 1 atm pressure, what volume of h 2 (g) can be obtained?
ra1l [238]
The balanced equation for the reaction between Mg and HCl is as follows
Mg + 2HCl --> MgCl₂ + H₂
stoichiometry of HCl to H₂ is 2:1

number of HCl moles reacted - 0.400 mol/L x 0.100 L = 0.04 mol of HCl
since Mg is in excess HCl is the limiting reactant 
number of H₂ moles formed - 0.04/2 = 0.02 mol of H₂

we can use ideal gas law equation to find the volume of H₂
PV = nRT 
where 
P - pressure - 1 atm x 101 325 Pa/atm = 101 325 Pa
V - volume
n - number of moles - 0.02 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in Kelvin - 0 °C + 273 = 273 K
substituting these values in the equation 

101 325 Pa x V = 0.02 mol x 8.314 Jmol⁻¹K⁻¹ x 273 K
V = 448 x 10⁻⁶ m³
V = 448 mL 
therefore answer is 
c. 448 mL
