Answer:
Gravity drives all mass wasting.
Explanation:
Mass wasting can be defined as the process of wasting away of earth's outer crust. This movement is also known as slope movement that causes large rock, soil, and debris to move downward, a force driven by gravity.
The term is often used interchangeably with landslide yet it is different. It is also known as mass movement as is cause massive downslope movement of rock, regolith, snow, ice, and-the-like on the earth's outer crust.
<u>All these movements are driven mainly by gravity. Gravity consantly tries to pull the rocks and soil down the slope but the resisting power. also known as shear strength, of moutains helps them to deny the gravitional force.</u>
Thus from the given options the statement that can be said to be true about mass wasting is that mass wasting is driven by gravity. So, the correct option is C.
One mole of a substance is defined by Avogadro as consisting of 6.022 x 1023 atoms. This is Avogadro's number. To calculate the number of atoms in two moles of sodium, use dimensional analysis. 2.0 moles Na x 6.022⋅1023g1mol=1.20⋅1024 atoms of Na
Alpha particles because two protons and two neutrons
Potassium 23.5g/39.0983g/mol = 0.601mol
The Ratio of reactants is 2 to 1 so (0.601mol)/2 = 0.3005mol
Therefore 0.3005mol of F2 is needed to find liters use
formula V = nRT/P (V)Volume = 22.41L
(T)Temperature = 273K or 0.0 Celsius
(P)Pressure = 1.0atm
<span>(R)value is always .08206 with atm n = 0.3005moles
(273)(.08206)(0.3005)/1 = V V = 6.7319 Liters</span>
Answer: [N2]₀ = 10M and [H2]₀ = 11M
Explanation: To calculate the initial concentration, you would have to set up an ICE table, which is an organized way of tracking known quantities or the ones you want to find. ICE stands for:
I is initial amount;
C is change in concentration;
E is for equilibrium concentration;
For the mixture,
N2 3H2 2NH3
I [N2]₀ [H2]₀ 0
C - x -3x +2x
E [N2]₀ - x =8 [H2]₀ - 3x =5 2x =4
With the product, we can find "x":
2x=4
x=2M
With x=2, find the concentrations:
[N2]₀ - x = 8
[N2]₀ = 10M
[H2]₀ - 3x = 5
[H2]₀ = 11M
The initial concentrations of nitrogen gas [N2] is 10.0 M and of hydrogen gas [H2] is 11.0 M.
