Answer: It passes through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km.
Explanation:
Answer:
temperatures within the outer core range from 7,200 to 9,000 F. Pressure also increases in the outer core due in part to the weight of the crust and mantle above.The Earth's magnetic field is generated by the outer core.
Explanation:
<span>The most efficient way to determine whether a reaction is an exothermic chemical reaction is to use a temperature probe.
Given that an exothermic chemical reaction is going to release heat, using an instrument such as a thermometer or a temperature probe to see the change in temperature would be the best way in order to determine the type of the chemical reaction.

Answer: Empirical formula is ![C_2H_{2}O](https://tex.z-dn.net/?f=C_2H_%7B2%7DO)
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of C= 60.87 g
Mas of H = 4.38 g
Mass of O = 34.75 g
Step 1 : convert given masses into moles.
Mass of C =
Moles of H =
Moles of O=
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For H =
For O =
The ratio of C:H:O= 2 : 2: 1
Hence the empirical formula is ![C_2H_{2}O](https://tex.z-dn.net/?f=C_2H_%7B2%7DO)
