Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
Answer:
57 grams of H3PO4
Explanation:
M= moles/ liters
convert mL to L
234 mL x 1L/1000mL = 0.234L
Rearrange the Molarity formula to solve for moles.
moles= MxL
moles= 2.5M x 0.234L
moles= 0.585 mol
Use the molar mass of H3PO4 to get to grams
0.585 mol x 97.994 grams/1 mol = 57.326 grams of H3PO4
round to two sig figs for 57 grams

Calcium has the greatest mass of the first twenty elements with a mass of approximately 40.08
Answer:
This is the temperature indicated by a moistened thermometer bulb exposed to the air flow. The evaporation is reduced when the air contains more water vapor. The wet bulb temperature is always lower than the dry bulb temperature but will be identical with 100% relative humidity.
