Answer:
It is commonly believed that the Catholic Church persecuted Galileo for abandoning ... Thus Galileo did not prove the theory by the Aristotelian standards of science in his day. ... If we believe Relativity, science never *can* disprove them. ... If you correctly report the findings of Fr. Spitzer, then he is wrong.

Answer:
In 1 mole of HCl is 36,46 grams
Explanation:
Molar mass of HCl = 1,01 (H) + 35,45 (Cl) = 36,46 g/mole
We use the formula n=m/M to calculate the mass
1 mole = m/ 36,46g/mol
mass = 36,46g/mole* 1 mole = 36,46 grams
Answer:
125.84 g/mol is the molar mass of the unknown gas.
Explanation:
Let the volume of the gases effusing out be V.
Effusion rate of the unknown gas =
Effusion rate of the nitrogen gas =
Molar mass of unknown gas = m
Mass of nitrogen gas = 28 g/mol
Graham's law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
125.84 g/mol is the molar mass of the unknown gas.
Answer:
4.6 x 10⁻⁶
Explanation:
In scientific notation, the number should be written in between 1 - 10 and multiplied by 10 raised to a power.
In this case, the decimal place should be placed in-between the 4 and the 6. To do this, you must move the decimal place 6 digits to the right. When you move the decimal place to the right, the 10 should be raised to a negative number.
As such, 0.0000046 in scientific notation is 4.6 x 10⁻⁶.
