Answer:
0.2 cm
Explanation:
looking at the ruler, you can see that the diameter is 0.4 cm. to get the radius, just divide by two, which gets 0.2 cm as the radius
<span>Answer:
Mass % KCL:
Add the grams of both compounds (31.0 g KCL + 225 g water) to find total mass and then divide the grams of KCL over the total mass, then multiply by 100: ( 31.0 g KCL / 31.0 g + 225 G) * 100%
Mole fraction KCL
Calculate the moles of KCL and water and add them to find the total moles (Moles of KCL + moles of water). Then, divide the number of KCL moles over the total moles.
moles of KCL/ moles kcl + moles water= mole fraction of KCL</span>
Answer:
neutralization reaction
Explanation: Because Neutralization Reactions. ... from a neutralization reaction
Answer is: thermal conduction.
<span>Thermal
conduction is the transfer of heat through physical
contact. Thermal conduction is the transfer of heat by
microscopic collisions of particles. Heat spontaneously flows from a
hotter to a colder body.
</span><span>The thermal energy of that core is transferred to the surface of the Earth and lower levels of the oceans by conduction. Water in lakes and oceans transfers heat to the surface by convection.</span>
