Answer:
c) billions
Explanation:
there are more than 0 stars, because our sun is a star
and there are more than one because the milky way has a lot of suns
there aren't infinite because the milky way is finite it has some volume and even you made the smallest star possible you wouldn't have infinite stars
so the only option is billions
Petroleum has less density than water. So, when fire streams are applied to the burning liquid surface at such an angle that hot and / or burning oil is forced over the edge of the tank, the oil then flows down the side of the tank and you are now confronted with a fire on the ground as well as the one in the tank.
<h3>What are the reasons not to use fire streams during deal with burning oil?</h3>
When you spray water on a regular fire, you're attempting to lower the flame's temperature and contain the fire.
Fuel for an oil fire is oil. Temperature and oxidizer are present in a fire (oxygen). Due to the fact that oil is lighter than water, an explosion may result if it floats above water while water sinks beneath oil.
Consequently, water shouldn't be used to put out oil fires.

Answer:
B. 2
Explanation:
The reaction expression is given as:
_S + 3O₂ → 2SO₃
Now let us balanced the expression;
On the product side we have 2 moles of S
On the reactant side we should have 2moles of S
So, we put the coefficient 2 to balance the expression;
We have 6 moles oxygen on both sides
Electrification is widely considered as a viable strategy for reducing the oil dependency and environmental impacts of road transportation. In pursuit of this strategy, most attention has been paid to electric cars. However, substantial, yet untapped, potentials could be realized in urban areas through the large-scale introduction of electric two-wheelers.
