Answer:
The temperatures get hotter.
Explanation:
Places closer/on the equator are facing the sun. Texas and Africa are located on the equator.
No, some impurities may alter the observed effects of a chemical reaction.. during a reaction other products may be produced, they may alter the MP or BP of the pure substance.
Volcanic activity, obviously by erupting volcanoes
Using the Equation: PV=nRT
Where P is the pressure 60 cmHg or 600 mmHg or 600/760= 0.789 atm
V is the volume 125 ml or 0.125 L, n is the number of moles, R is a constant 0.082057, and T is temperature 25 °C or 298 K;
Therefore:
0.789 × 0.125 = n × 0.082057 × 298
n = 0.0987/24.45
= 0.004036 mol
0.004036 mole has a mass of 0.286 g
Hence; 1 mole has a mass of 0.286/0.004036
= 70.8 g /mol
Therefore the molar mass of the gas is 71 g/mol (2 sfg)
