Answer is: mass of water is 432 grams.
Chemical reaction: 2H₂ + O₂ → 2H₂O.
m(O₂) = 384 g.
M(O₂) = 2 · 16 g/mol = 32 g/mol, molar mass.
n(O₂) = m(O₂) ÷ M(O₂).
n(O₂) = 384 g ÷ 32 g/mol.
n(O₂) = 12 mol, amount of substance.
From chemical reaction: n(O₂) : n(H₂O) = 1 : 2.
n(H₂O) = 12 mol · 2 = 24 mol.
m(H₂O) = n(H₂O) · M(H₂O).
m(H₂O) = 24 mol · 18 g/mol.
m(H₂O) = 432 g.
Answer:
mass (m) of the snow that the backpacker collected= 0.855 kg
Explanation:
Given that:
Q = 643 kJ = 643000 J
ΔHfusion = 6.02 kJ/mol = 6020 J/mol
number of mole of water H2O = 
c = 4.18 J/g⋅K
ΔT = 100 K
Since there is a phase change from solid to liquid; then :
ΔH = 
However without the given mass; we substitute 
for the number of moles; so:
Q = 
m = 855 g
m = 0.855 kg
mass (m) of the snow that the backpacker collected= 0.855 kg
Answer and Explanation:
In most of the cases a neurotransmitters is discharged based on what's known as the axon terminal after an activity potential has arrived at the neurotransmitter, a spot where neurons can transmit sign to one another. These cells contain receptors where the synapses can tie and trigger changes in the cells.
Neurotransmitters are put away in synaptic vesicles, bunched near the cell film at the axon terminal of the presynaptic neuron. Synapses are discharged into and diffuse over the synaptic split, where they tie to explicit receptors on the film of the postsynaptic neuron.
Answer:
I think this is like a game in which you need dice.
Explanation:
To fill out the second page, you need to complete the roll/go-to chart.
The water vapor will begin to contract. The particles will begin to bond with each other to seek heat so they're contracting.
