Answer:
A. Dry with low humidity
Explanation:
Atmosphere is the layer of gases that surrounds the earth above air layer. Its conditions affect our climate.
The hydrosphere includes the water which is on the surface of the earth,below the ground and in the air.
Tropics are the region of our earth surrounding the equator.
On analyzing the climatic conditions in the tropics due to the interaction of the atmosphere and hydrosphere, the presence of water droplets in tropics is less resulting in less humidity and, thus the climatic condition is dry.
Therefore the climatic condition that is typically found in tropics due to interaction of the atmosphere and hydrosphere is dry with low humidity.
The common way the scientific knowledge is discovered passes through several steps:
First you observe the phenomenon around you. Then you develop a certain hypothesis based on your observation. After that you start testing your hypothesis and collecting the resultant data from your tests.
Finally comes the conclusion of whether your hypothesis is accepted or rejected.
If it is accepted, it can further develop into a theory and a publication afterwards.
The answer is: hypothesis

Chromium = 51.9961 u
Answer:
84.4g of AgCl
Explanation:
Based on the reaction:
2AgNO₃ + CaCl₂ → 2AgCl + Ca(NO₃)₂
<em>2 moles of AgNO₃ and 1 mole of CaCl₂ priduce 2 moles of AgCl and 1 mole of Ca(NO₃)₂</em>
<em />
100g of each reactant are:
AgNO₃: 100g × (1mol / 169.87g) = 0.589 moles
CaCl₂: 100g × (1mol / 110.98g) = 0.901 moles
For a complete reaction of 0.901 moles of CaCl₂ are necessaries 0.901×2 = <em>1.802 moles of AgNO₃. </em>As there are just 0.589moles, <em>AgNO₃ is limitng reactant</em>
<em></em>
0.589 moles of AgNO₃ produce:
0.589 moles × ( 2 moles AgCl / 2 moles AgNO₃) =
<em>0.589 moles of AgC</em>l. In mass:
0.589 moles of AgCl × (143.32g / mol) =<em> 84.4g of AgCl</em>
