Answer:

The half-life () is a timescale on which the initial population is decreased by half of its original value, represented by the following equation. This indicates that the half-life of a first-order reaction is a constant. Figure 2: Half lives graphically demonstrated for first-order reaction.

Which of the following is a molecular formula for a compound with an empirical formula of CH2O and a molar mass of 150. g/mol.
trapecia [35]

Answer:

C₅H₁₀O₅

Explanation:

Let's consider a compound with the empirical formula CH₂O. In order to determine the molecular formula, we have to calculate "n", so that

n = molar mass of the molecular formula / molar mass of the empirical formula

The molar mass of the molecular formula is 150 g/mol.

The molar mass of the empirical formula is 12 + 2 × 1 + 16 = 30 g/mol

n = (150 g/mol) / (30 g/mol) = 5

Then, we multiply the empirical formula by 5.

CH₂O × 5 = C₅H₁₀O₅

V125BC [204]

Answer:

Number of proton emmitted by laser=2.48*10^17proton

Explanation:

Energy is the ability to cause change; power is directly proportional to energy and its the rate energy is utilized.

Power=energy/time.

First we need to calculate the total energy used which is equal to the total power utilized.

E(total)= P( total) = 1.4W × 0.070 s =0.098J
