Answer:
435.38 L
Explanation:
From the question,
Applying ideal gas equation,
PV = nRT................... Equation 1
Where P = Pressure, V = Volume, n = number of moles, R = molar gas constant, T = Temperature.
Since Temperature and Pressure were constant,
V ∝ n
V/n = V'/n'.................... Equation 2
Where V and V' = the initial and final Volume of Ar respectively, n and n' = the initial and final moles of Ar respectively
make V' the subject of the equation
V' = Vn'/n............... Equation 3
Given: V = 100 L, n = 3.25 mol, n' = 14.15
Substitute into equation 3
V' = (100×14.14)/3.25
V' = 435.38 L
A. The atom has 3 protons, 3 electrons, and 4 neutrons.
Answer:
Explanation:
The atomic weight of oxygen = 15.9994 g
This mass corresponds to 1 mole of the oxygen atoms.
Thus,
15.9994 g mass of oxygen contains 
atoms of oxygen.
1.4 kg = 1400 g ( 1 kg = 1000 g)
So,
1400 g mass of oxygen contains 
atoms of oxygen.
Number of atoms in 1400 g of oxygen = 
Also, 1 atom of oxygen contains 8 protons
Charge of 1 proton = + 
So, Charge on 1 atom of oxygen = 
Thus,
Charge on atoms of oxygen = 
Thus, positive charge in 1.4 kg of oxygen =
Cross-pollination
occurs when pollen from one plant transferred to a different plant with same
species. <span>The two
plants’ genetic material combines and the resulting seeds from that pollination
will have characteristics of both varieties thus producing stronger
plants. In addition, cross- pollination happens
in several means through the help of wind, insect or humans. </span><span>

Answer:
Explanation:
Hello!
In this case, since the heat involved during a heating process is computed in terms of mass, specific heat and temperature change as shown below:
Thus, since the heated mass of water was 88 g, the specific heat of water is 4.184 J/g°C and the temperature change is 6.0 °C, we can compute the heat as shown below:
