Answer:
The molar mass and molecular weight of Sn(CO3)2 is 238.728.
Explanation:
I think that is called a Metamorphic rock.
Answer:
2 M
Explanation:
mole weight of CaBr2 = 40 + 2 * 79.9 = 199.8 gm
20 gm is then 20/199.8 =.1 mole
.1 mole / .50 liter = 2 M
Answer:
1) Condensation.
2) See below.
Explanation:
1) The warmer water vapour from the surroundings came into contact with the cooler inner surface of the glass jar and condensed, forming the water droplets (water vapour) on the inside of the glass jar.
2) As condensation occurs, condensed water vapour will drip into the water solution in the glass jar, causing the water to rise in the glass jar.
