Answer:
Explained below
Explanation:
The human body has a normal core temperature of around 37°C to 38°C.
Now, if it is heated up to say 39° to 40°C, fatigue will start to set in and the brain begins to tell the muscles to slow down.
If it's now heated to higher temperatures above above 41°C, the body will begin to experience heat exhaustion and therefore will start to shut down.
Due to this process, the body can't even sweat at that stage because blood flow to the skin will stops thereby making the body feel cold and clammy. Thus, chemical processes/reaction in the body will begin to be affected and the cells inside the body will start to deteriorate and thus there is now a huge risk of having multiple organ failure.
Answer:
Concentration
Explanation:
Amount of substance concentration often called simply concentration, is a quantitative measure of the number of atom s per unit volume in a sample of a matter.
The natural abundance of bromine in general in nature is 100%.
This means that:
the natural abundance of Br-79 + the natural abundance of Br-80 = 100
We know that the natural abundance of Br-79 is 50.69%. This means that the natural abundance of Br-80 is the rest of the 100%.
Natural abundance of Br-80 = 100% - 50.69% = 49.31%
Answer:
mass of CO2 = 88 g
Explanation:
It is stated in question that 18.7 g of oxygen remained unreacted which means that carbon is limiting reactant. Thus the amount of carbon dioxide produced depend upon the amount of carbon.
Given data:
mass of carbon = 24 g
total mass of oxygen 82.7 g
mass of unreacted oxygen = 18.7 g
mass of carbon dioxide = ?
Solution:
First of we will calculate the moles of carbon.
number of moles of carbon = mass of carbon / atomic weight
number of moles of carbon = 24 g/ 12 g/mol = 2 mol
Chemical equation:
C + O2 → CO2
now we compare the number of moles of carbon and carbon dioxide,
C : CO2
1 : 1
2 : 2
Now we will calculate the mass of carbon dioxide from moles.
number of moles of CO2 = mass of CO2 / molar mass of CO2
2 mol × 44 g/mol = mass
mass of CO2 = 88 g
Answer:
Usually you have V, for voltage, Ohms for resistance, and Coulombs for charge.
