Determine the stoichiometric ratio of moles of any reactant to moles of CO2. For instance, if your equation is CaC03 + 2HCL => CaCl2 + CO2 + H2O, then the ratio of moles of CaCO3 to CO2 is 1:1. For every mole of CaCO3 that you are using, you have one mole of CO2.
Answer:
The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. ... Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona, which in turn is a result of the coronal magnetic field.
Explanation:
Answer:
The student's speed is 60 mph.
Explanation:
All you have to do is divide: 260/4 = 60 mph.
A) hot water
i believe this is the correct answer because the molecules are moving around more and this allows the food coloring to mix in with the hot water quicker than the other types of water
Answer:
Empirical formular = CH₂
Molecular formular = C₃H₆
Explanation:
Percent Mass of C = 85.63%
Percent Mass of H = 14.37%
Molar mass = 42.0 g/mol
Steps in Calculating the Empirical Formular;
1 - Divide the percent mass of the Elements with their respective atomic masses. Carbon = 12 and Hydrogen = 1
Carbon = 85.63 / 12 = 7.14
Hydrogen = 14.37 / 1 = 14.37
2 - Divide the values by the smallest one. In this case Carbon has the lowest value of 7.14
Carbon = 7.14 / 7.14 = 1
Hydrogen = 14.37 / 7.14 = 2.013
3. Approximate the values to the nearest whole number.
Hydrogen ≈ 2
Hence the empirical formular is given as; CH₂
Molecular formular is given as;
[12 + 2(1)]n = 42
14n = 42
n = 3
Molecular formular = C₃H₆
