the average weight of a frog is 0.8 ounces, so your answer would be 4
Answer:
B- Lower temperature causes a reduction in movement
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space
Answer:
0.416moles
Explanation:
Using the formula;
number of moles = mass ÷ molar mass
Molar mass of CO2 = 12 + 16(2)
= 12 + 32
= 44g/mol
According to the information in this question, there are 18.3g of CO2
number of moles (n) = 18.3/44
= 0.4159
= 0.416moles of CO2
