Answer:
in this situation I would a little bold
Explanation:
first I don't know what extinguisher I would use pretty much any that helps with fires. I'll back people up, take the hood and put it on the small fire that way it will light out more and if I open the hood and there still a little fire I would use the extinguisher and no one gets hurt :)
Answer:
false
Explanation:
cuz carbon dioxide is greenhouse gasses
Answer:
Explanation:
Hello,
In this case, we can use the ideal gas equation:
So we know the temperature, pressure and volume, therefore we can easily compute the required moles as shown below:
Best regards.
Answer: They are typically smaller than spiral galaxies.
Some show evidence for prior collision or close encounter with another galaxy.
They exhibit vigorous star-forming activity.
Irregular galaxies are typically smaller than spiral or normal ellipticals, of irregular form, and without spiral arms. Irr I galaxies are often characterized by lots of gas, dust, and associated star formation. Irr II galaxies have forms that indicate prior collisions or close encounters with other galaxies. Irregular galaxies are one of the most common types of galaxies.
The number of ions of Mg and F that started is
10 ions of Mg and 20 ions of F ( answer A)
<u><em>Explanation</em></u>
MgCl2 (aq) + 2 AgF(aq) → 2AgCl(s) + MgF2 (aq)
from equation above the mole ratio of MgCl2 :AgCl is 1 :2 therefore the number of Mg ions = 20 x 1 /2 = 10 ions
The mole ratio of AgF: AgCl is 2:2 therefore the number of F ions
=20 ion x2/2 = 20 ions
