Answer:
the answer is evaporation
Explanation: Evaporation is the process by which a liquid transforms into vapor (a gas). When some material is in its liquid phase, its particles are really close together (but not as much as we would see in a metal). As the temperature of the liquid increases, also does the kinetic energy of the particles. This cause the particles in the water to move a lot faster, thus its oscillations are larger. This causes an increase in the volume of the material.
Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
Answer:
saharan africa
Explanation:
. Roman roads are spread to northern Africa.
if the archeologist would go to sub Sahara Africa, he would be more likely to fijd the roads.
he could also go to Israel. the Roman's made a stone paved road and some people while traveling it dropped coins. if he were to look for the coins, he would find the road.
The best word to replace "have" is the word "manage".
<h3>What is an effective word?</h3>
A word is considered effective/ineffective depending on whether the word transmits the author's message. In the case of Nancy, she wants to show students struggle as they deal with classes, homework, and extracurricular activities.
<h3>How to replace the word "have"?</h3>
The word "have" is ineffective because it does not completely show how difficult the situation is for students. One word that can show this struggle is "manage" because this emphasizes Nancy's point of view.
