Explanation:
the earth revolves around the Sun once each year and spins on its axis of rotation once each day. This axis of rotation is tilted 23.5 degrees relative to its plane of orbit around the Sun. The axis of rotation is pointed toward Polaris the North Star. As the Earth orbits the Sun the tilt of Earth’s axis stays lined up with the North Star.
Answer:
The particles in a solid vibrate in place.
Explanation:
The particles in a solid are close and tightly packed together so they have no room to flow past each other like the particles in a liquid can.
Hope this helps!
Answer:
CO is considered as a product.
Explanation:
A general chemical equation for a combination reaction follows:
To write a chemical equation, we must follow some of the rules:
The reactants must be written on the left side of the direction arrow.
A '+' sign is written between the reactants, when more than one reactants are present.
An arrow is added after all the reactants are written in the direction where reaction is taking place. Here, the reaction is taking place in forward direction.
The products must be written on the right side of the direction arrow.
A '+' sign is written between the products, when more than one products are present.
For the given chemical equation:
are the reactants in the reaction and are the products in the reaction.
Hence, CO is considered as a product.
Answer:
option B.
Explanation:
Given,
V₁ = 156 L
P₁ =2 atm
Now, in the cylinder
P₂ = ?
V₂ = 36
Using relation between pressure and volume
![\dfrac{P_1}{V_2}=\dfrac{P_2}{V_1}](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1%7D%7BV_2%7D%3D%5Cdfrac%7BP_2%7D%7BV_1%7D)
![\dfrac{2}{36}=\dfrac{P_2}{156}](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B36%7D%3D%5Cdfrac%7BP_2%7D%7B156%7D)
![P_2 = 8.67\ atm](https://tex.z-dn.net/?f=P_2%20%3D%208.67%5C%20atm)
Hence, pressure is equal to 8.67 atm.
Hence, the correct answer is option B.
