Answer:
answer is electron cloud model
Answer: C) It increases with a decrease in the concentration of . D) It decreases with increase in the concentration of .
Explanation: According to Le Chatelier's principle, if an equilibrium reaction is disturbed, the reaction would try to undo the change imposed.
Thus if the concentration of the products in increased, the reaction would shift in a direction where the concentration of products is decreasing i.e in backward direction.
If the concentration of the products in decreased, the reaction would shift in a direction where the concentration of products is increasing i.e in forward direction.
When the concentration of either of the products, i.e or is increased, the reaction will shift in backward direction and the rate of forward direction decreases.
Answer:
6 x 10⁵ kg Hg
Explanation:
The mass of mercury in the entire lake is found by multiplying the concentration of the mercury by the volume of the lake.
The volume of the lake is calculated in cubic feet:
V = (SA)x(depth) = (100mi²)(5280ft/mi)² x (20ft) = 5.57568 x 10¹⁰ ft³
Cubic feet are then converted to mL (1cm³=1mL)
(5.57568 x 10¹⁰ ft³) x (12in/ft)³ x (2.54cm/in)³ = 1.578856752 x 10¹⁵ mL
The mass of mercury is then found:
m = CV = (0.4μg/mL)(1g/10⁶μg)(1kg/1000g) x (1.578856752 x 10¹⁵ mL) = 6 x 10⁵ kg Hg
Answer:
f = 0.94 ×10²⁴ Hz
Explanation:
Given data:
Frequency of light = ?
Wavelength of light = 3.2 ×10⁻¹⁶ m
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = f × 3.2 ×10⁻¹⁶ m
f = 3×10⁸ m/s / 3.2 ×10⁻¹⁶ m
f = 0.94 ×10²⁴ s⁻¹
f = 0.94 ×10²⁴ Hz (Hz = s⁻¹)
