With a process called Fission. This generates heat to produce steam.
True, because diatomic elements (H2, O2, F2, Br2, I2, N2, Cl2) consist of only one element but are molecules with covalent bonds.
Answer:
4.79x10¹³s⁻¹
Explanation:
For a first order reaction, the graph of ln k against 1/K follows Arrhenius equation:
lnK = ln A - Ea/RT
<em>Where A is pre-exponential factor, Ea is activation energy, R gas constant and T is absolute temperature</em>
<em />
If you graph ln k = y and 1/T = x:
y = lnA - Ea/R x
<em>Where the slope = -Ea/R</em>
<em>And the intercept = lnA</em>
<em />
To solve the pre-exponential factor:
31.5 = lnA
e^31.5 =
<h3>4.79x10¹³s⁻¹</h3>
s⁻¹ because the reaction is first order.
Answer:
This is because their atoms have the same number of electrons in the highest occupied energy level. Li lithium and K potassium both belong to first group (alkali metals) and thus have similar chemical properties.
Explanation:
Answer:
200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.
Explanation:
Mass of solution = M
Mass percentage of the solution of lime = 15%
Mass of lime or calcium hydroxide = m = 30 g
The Formula of mass percentage is given as :
On substituting the values in ab above formula :
200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.
