Answer:
Number of moles = 0.042 mol
Explanation:
Given data:
Number of moles = ?
Mass of calcium carbonate = ?
Solution:
Formula:
Number of moles = mass/ molar mass
now we will calculate the molar mass of calcium carbonate.
atomic mass of Ca = 40 amu
atomic mass of C = 12 amu
atomic mass of O = 16 amu
CaCO₃ = 40 + 12+ 3×16
CaCO₃ = 40 + 12+48
CaCO₃ = 100 g/mol
Now we will calculate the number of moles.
Number of moles = 4.15 g / 100 g/mol
Number of moles = 0.042 mol
Pretty sure it's 6 the atomic mass
Answer/Explanation:
A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.
Answer:
Genetic information from a single parent is copied and passed on to form offspring with the same genetic information. During asexual reproduction in a yeast cell, two daughter buds are formed.
Explanation:
Answer:
Convection is a heat transfer mechanism where heat moves from one place to another through fluid currents. Forced convection is simply using this mechanism in a useful way to heat or cool a home efficiently, such as using a fan.
