Answer:
Precipitation
Explanation:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).
Answer:
Mass of hydrogen produced =2.28 g
Explanation:
Given data:
Mass of tin = 67.3 g
Mass of hydrogen produced = ?
Solution:
Chemical equation:
Sn + 2H₂O → SnO₂+ 2H₂
Number of moles of Sn:
Number of moles = mass/ molar mass
Number of moles = 67.3 g/ 118.71 g/mol
Number of moles = 0.57 mol
Now we will compare the moles of tin with hydrogen from balance chemical equation.
Sn : H₂
1 : 2
0.57 : 2×0.57 = 1.14
Mass of hydrogen:
Mass = number of moles ×molar mass
Mass = 1.14 mol × 2 g/mol
Mass = 2.28 g
Answer:
The answer is 0.188L
Explanation:
I did the problem on paper and put the answer on the pictures. I'm sorry if I didn't explain it well but I hope I helped.
The answer is 35000
0.35 multiple by 100000
So it will give u 35000
The position of the solids in order from Lowest melting point to highest melting point are:
- Non-polar molecular - polar molecular -ionic solids - Covalent network.
<h3>What is meant by melting of point?</h3>
The melting point is a term that is defined as the point at which any given materials is altered from a solid to a liquid.
Note that the temperature at which solid is altered its said state to liquid at atmospheric pressure is seen as the melting point of that given liquid.
Hence, The position of the solids in order from Lowest melting point to highest melting point are:
- Non-polar molecular - polar molecular -ionic solids - Covalent network.
