From the data obtained from the tests, the actual boiling point lies between 34°C and 40°C.
The boiling point of a substance is the temperature at which the pressure of the substance becomes equal to atmospheric pressure. Pure substances have a sharp boiling point while impure substances boil over a temperature range.
In this case, the boiling point of the substance after 10 tests is obtained as 37+/−3°C. This implies that the actual boiling point lies between 34°C and 40°C.

Answer: Carbon emissions
Explanation: Mankind is creating excessive carbon emissions with his factories and machines.
The Bohr model is an inaccurate model because there is no way to measure the exact position or location of an electron in an atom.
Hey there!:
Molar mass NaOH = 39.997 g/mol
Number of moles ( solute )
n = mass / molar mass
n = 1.00 / 39.997
n = 0.0250 moles of NaOH
Volume in liters:
500.0 mL / 1000 => 0.5 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.0250 / 0.5
Molarity = 0.05 M
Hope that helps!
The best answer is:
a. Extrusive igneous rocks
In general, rocks that are formed by the cooling of magma are classified as igneous rocks. The key word however in this case is "lava," which is magma that reached the surface. This is what makes it an extrusive igneous rock, because it formed in the surface.
