Answer:
78.5 mL
Explanation:
Step 1: Given data
Mass of the lead fishing weight: 39.7 g
Volume of water in the graduated cylinder: 75.0 mL
Step 2: Calculate the volume of the lead fishing weight
The density of lead is 11.34 g/mL.
39.7 g × (1 mL/11.34 g) = 3.50 mL
Step 3: Calculate to what volume will increase the water level
The final volume of water will be equal to its initial value plus the volume displaced by the lead fishing weight.
V = 75.0 mL + 3.50 mL = 78.5 mL
Answer: C. 146 g
Explanation:
To calculate the moles, we use the equation:
Thus
For sodium nitrate
moles = 1.72
Molar mass of sodium nitrate = 85g/mol
Putting values in above equation, we get:
Answer:
Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature. ... Without water, animals become weak and confused, and they can die if they do not rehydrate. For example, if a plant is adapted to low temperatures and the specific are where it lives, has a change in its temperature(thanks to global warming!), this plant will die and this area will no longer support life, which is due to the change in abiotic factor (temperature) Many forces influence the communities of living organisms present in different parts of the biosphere (all of the parts of Earth inhabited by life). The biosphere extends into the atmosphere (several kilometers above Earth) and into the depths of the oceans. Despite its apparent vastness to an individual human, the biosphere occupies only a minute space when compared to the known universe. Many abiotic forces influence where life can exist and the types of organisms found in different parts of the biosphere. The abiotic factors influence the distribution of climates, flora, and fauna. so the answer is C
Explanation:
Pls brainlist :) hope I helped.
Given that the liquid conserves the volume, when it is changed from one container to another, the kinetic molecular theory predicts no change in the velocity of the molecules, which means that the temperature will not change.
Answer:
After checking many websites as well
I haven't seen any answer for this reaction
While I found answers or other reactions
Therefore I think this reaction cannot occur
