Global winds occur due to
<u>1. Choose...</u>
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
over a large area and this forms
2. Choose...
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
caused by cool and warm air.
Answer:
<u>1. d. uneven heating</u>
<u>2. b. convection currents</u>
Explanation:
1. What Beto should know is that as the earth moves and rotates around the sun, some parts of the Earth receive more sunlight and others less, which then leads to uneven heating over a large area of the earth.
2. This uneven heat then forms a convection current containing varying patterns of air spreading to various parts of the globe.
Answer:
Remember that there are 5 moles of water for every 1 mole of hydrate
159.61g mol−1(159.61+5×18.015)g mol−1×100=63.92% CuSO4
This tells you that for every 100 g of copper(II) sulfate pentahydrate, you get 63.92 g of anhydrous copper(II) sulfate. Use this as a conversion factor to get
1.596g CuSO4⋅100 g CuSO4⋅5H2O63.92g CuSO4=2.497 g CuSO4⋅5H2O
Rounded to two sig figs, the answer will be
N2 + 3H2 = 2NH3
in this question, we are dealing with only NH3 and H2 so we only focus on that
since the ratio of H2 to 2NH3 is 3:2, we say that
3 liters of H2 = 2 liters of 2NH3
3.6 litres of H2 = x liters of 2NH3
We cross multiple to give:
3 × x = 3.6 × 2
3x = 7.2
Divide both sides by 3
x = 7.2 ÷ 3
x = 2.4liters
Gene therapy is only effective against genetic disorders such as autoimmune diseases or some cancers. Bacteria are pathogens that independently attack and infect the body, modifying the genes of the host will not be effective in an immune response. Bacteria must be destroyed via a natural immune response or antibiotics.
