Aluminum foil I think but if not goodluck :)
It has more electrons, meaning more orbitals, pls give brainliest.
Answer:
Almost 3 snicker's bar will contain the worth of energy stored in the battery which makes option A correct (Fewer than 5)
Explanation:
Step 1
The energy stored in a charged battery is 840 Watt- hours
Recall from the question that 1 KWh = 3600 KJ
So how many Kilo-joules will be in 840 Watt- hours?
I will convert 840 Watt- hours to KWh = 840 / 1000
= 0.840 KWh
Since I KWh gives 3600 KJ
then, 0.840 KWh will give x
x = 3024 KJ
3024 KJ of energy is stored in the battery
Step 2
A snicker bar contains 250 cal and 1 cal = 4.184 KJ
Convert 250 cal to KJ?
250 cal = 1046 KJ
Each snicker bar contains 1046 KJ
To calculate how many snicker's bar worth energy stored in the battery will be (y) ?
y = 3024 / 1046
y = 2.9 snicker's bar approximately 3
The correct option is Fewer than 5
The pOH of a solution with [OH] = 9.0 × 107 will be D (6.04).
<h3>What is ph value?</h3>
A ph value is the measure of acidity and the basics of a substance or solution.
Given;
[OH] = 9.0 × 10^7
pOH = - log [OH⁻]
pOH = - log (9.0 x 10⁻⁷)
pOH = 6.0457
Hence, The pOH of a solution with [OH] = 9.0 × 107 will be D (6.04).
