answer: white fur works as a camouflage against the white snow, allowing polar bears an advantage when hunting for food and hiding from predators
Answer:
Heat by radiation will most likely be transferred through empty space by thermal radiation.
Explanation:
Radiation is method in which heat is transferred without depending upon the contact of heat source and the heated object, which happens in the case of conduction and convection. The heat can be transferred through the empty space by the help of thermal radiation. This complete phenomenon is called as the infrared radiation. Which is a type of electromagnetic radiation. The heat is found to be convected in the atmosphere when the warm particles are transferred from one location to another.
Answer:
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.
Explanation:
Hey there!
SiO₂ + HF → SiF₄ + H₂O
The problem here is that there is not an equal amount of O, H, or F atoms on both sides of the equation.
So let's balance!
Balance F.
1 on the left, 4 on the right. Add a coefficient of 4 in front of HF.
SiO₂ + 4HF → SiF₄ + H₂O
Balance H.
4 on the left, 2 on the right. Add a coefficient of 2 in front of H₂O.
SiO₂ + 4HF → SiF₄ + 2H₂O
Balance O.
2 on the left, 2 on the right. Already balanced.
Balance Si.
1 on the left, 1 on the right. Already balanced.
Our final balanced equation: SiO₂ + 4HF → SiF₄ + 2H₂O
Hope this helps!
Answer:
a molecule
Explanation:
A molecule is the smallest unit quantity of a compound which can exist by itself and retain ALL the properties of the original substance.
