Answer: Hurricane is not a man-made environmental change.
Explanation:
Changes which take place naturally in the environment without any force or work done by man towards causing that change are called non-man made environmental changes.
For example, hurricane is a natural environment change because a hurricane is formed moist and warm air above water surface of sea, oceans or rivers begin to rise.
This rising air is replaced by the cooler air present in the atmosphere. The continuation of this process leads to the formation large clouds and thunderstorms which occurs in the form of hurricane.
Whereas pollution is caused by vehicles driven by man, from chimneys of factories etc. So, it is a man-made environmental change.
Chemical spill can occur due to mishandling by man in laboratories or chemical labs.
Deforestation also occurs by man as they cut the trees for various needs to theirs.
Thus, we can conclude that hurricane is not a man-made environmental change.
Answer:
<h3>The answer is 112.36 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 53 mL
density = 2.12 g/mL
We have
mass = 2.12 × 53
We have the final answer as
<h3>112.36 g</h3>
Hope this helps you
Intermolecular forces are forces of interaction that are operative between two different molecules. They are of follow types
1) Dipole- dipole interaction
2) Hydrogen bonds
3) vander Waal's forces
Depending upon the polarity and constitution molecule above forces are operable.
for instance, in case of ammonia, Hydrogen bonds exist because hydrogen atom is attached to electronegative element i.e. N
HCl and CO are polar molecules, so dipole-dipole interaction is operative in these molecules.
Finally in case of CO2, vander Waal's forces of interaction is operable because it is a non-polar molecule.
I think it's Almond Soy Milk because they're recommending your body's pH to be at 7.5 and the Almond Soy Milk is the answer with the closest pH to 7.5
Answer: 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
Explanation:
1) Chemical equation:
Formaldehyde + oxgyen → CO₂ + H₂O
H₂CO + O₂ → CO₂ + H₂O
2) That equation is already balanced
3) Mole ratios
1 mol H₂CO : 1 mol O₂ : 1 mol CO₂ : 1 mol H₂O
4) Then, every mol of mol of H₂CO produces 1 mol of CO₂ , which means that 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.
