Answer:
gravitational pull generates something called tidal force.
Explanation:
High and low tides are caused by the moon. the moons gravitational pull generates tidal force.
Rate = k[A] = first order reaction
<h3>Further explanation</h3>
Given
Rate law
Required
A first-order reaction
Solution
The rate law : equation for the rate of chemical reaction
For reaction
aA + bB ⇒ C
The rate : r = k[A]ᵃ[B]ᵇ
The sum of exponents(a+b) is the reaction order
From the choice :
a. a+b = 2, second order reaction
b. a+b = 3, third order reaction
c. a+b = 4, fourth order reaction
d a+0 = 1, first order reaction
Answer:
17.6% is the percentage error
Explanation:
The percentage error is used to determine accuracy of a measurement (That is, how closely is the measure to the real or theoretical value). The equation is:
|Measure - Real| / Real * 100
In the problem, the measure was 22.7cm³ and real value is 19.3cm³. Solving for percentage error:
|22.7cm³ - 19.3cm³| / 19.3cm³ × 100
<h3>17.6% is the percentage error</h3>
Answer:
Hydrogen bonds are totally different to both covalent bonds and ionic bonds. Hydrogen bonds are intermolecular bonds, that means they occur in between two molecules. ... When H atom is close to O,F, N atoms those atoms can attract H atoms electrons temporarily, thus making a weak bond.
