Explain why a halogen bulb has a longer bulb life than a traditional incandescent bulb filled with argon.

1 answer:

4 0

Answer:

The halogen bulb lasts longer because the filament lasts longer. It can have twice the life of an incandescent and use the same amount or slightly less (10%) electricity.

A student measures a mass of an 8cm3 block of brown sugar to be 19.9G. what is the density of the brown sugar?

Naily [24]

Answer:

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question we have

$density = \frac{19.9}{8} \\ = 2.4875$

We have the final answer as

Is kp or kc larger (both at 300 k) for the reaction 2 nh3(g) ⇀↽ n2(g) + 3 h2(g) ? 1. they are both the same. 2. kc is larger. 3.

fgiga [73]

The equation is 2 NH3 (g) â‡€â†˝ N2 (g) + 3 H2 (g)
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.
