Answer:
its C
Explanation:because the "veins" that go through the plant is what transfers the water
Answer:
Ammonium carbonate is a neutral molecule. Charge on NH4 is +1 , so on (NH4)2 is +2 ( +1 * 2) ,lets take the charge on C to be x and O is -2 , so on O3 is -6 (3*-2). Therefore x= + 4. Hope it helps.
Explanation:
Answer is:
1: Kr.
2: Cl₂.
3: F₂.
4: O₂.
5: N₂.
6: He.
The lighter (smaller) particles move more quickly than heavier (larger) ones at the same temperature.
Calculate molar masses of the compounds:
M(Cl₂) = 70.9 g/mol; molar mass of chlorine gas.
M(F₂) = 38 g/mol, molar mass of fluorine gas.
M(He) = 4.002 g/mol; molar mass of helium.
M(Kr) = 83.8 g/mol; molar mass of krypton.
M(N₂) = 28.01 g/mol; molar mass of nitrogen gas.
M(O₂) = 32 g/mol; molar mass of oxygen gas.
Answer:
hydrogen gas
Explanation:
Zn + 2HNO3 ------ Zn(NO3)2 + H2⬆️
Since there aren't grams and just moles, the theoretical yield is one whole mole. If the molar mass is <span>142.04 g/mol, that is your answer. Hope I helped!</span>
