Answer:
precipitation means water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.

<span>So we need 0.276 moles of HCl to react. Your concentration is given in moles/liter so 0.276/1.58 = 0.174 liters needed or 174 milliliters</span>
False
Explanation:
The geologic time scale which simplifies earth's long history is broad division of deep time. It consists of a large and small divisions.
- The geologic time scale is divided into large broad categories; called eons, eras, period and epoch.
- The scale is merges absolute dating of events that has happened in geologic past and their relative ages.
- Broad categories on the scale are further simplified into smaller units.
- Relative age puts events in the order of their appearance using a couple of geologic principles.

Answer:
0.109 g.
Explanation:
Equation of the reaction:
Na3PO4 + 3HCl --> 3NaCl + H3PO4
Number of moles of HCl = molar concentration × volume
= 0.1 × 0.04
= 0.004 mol.
By stoichiometry, 1 mole of Na3PO4 neutralises 3 moles of HCl. Therefore, number of moles of Na3PO4 = 0.004/3
= 0.0013 mol
Mass of Na3PO4 = molar mass × number of moles
= 0.0013 × 164
= 0.219 g
Since 50% of Na3PO4 was present in the sample. Let 100 g be the total mass of the substance
= 0.219 × 50 g/100 g
= 0.109 g.
Things go sublime when changing automatically into vapor when it is heated, usually forming a solid figure.
