Answer:
Answer: B. Water condenses to form clouds.
Explanation:
When the moisture condenses, this results in the release of energy. The energy causes the air to be warm and results in the rise of air in the upper atmosphere. This process results in the instability in the atmosphere and cumulonimbus clouds are formed. These clouds support lightening during a thunderstorm.
Answer:
3.96 MINUTES
Explanation:
Karl likes to use cruise control when he drives on
the highway. After setting cruise control at 33.53
m/s (75 mph). At this speed, how long would it
take Karl to travel 8 kilometers?
VELOCITY = DISTANCE/TIME
OR
V=D/T
SO
VT=D
SO
T=D/V
THE DISTANCE IS 8 KM
THE VELOCITY IS 75 MPH
THERE ARE 1.61 KM PER MILE
SO
75M[H =
75 X 1.61 KM/H =
121 KM/HR
T=D/V
T=8/121 =0.066 HOUR =
0.066 X 60 MINUTES =
3.96 MINUTES
CHECK
75 MPH =
(75 X 1.61) KM/60 MINUTES =
120,75 KM/60 MINUTES=
2.01 KM/MINUTE
to travel 8 K,M WILL TAKE
8/2.01 = 3.98 minutes
The number of moles of H₂ that are needed to react with 2.0 moles of N₂ is 6.0 moles
<u><em>calculation</em></u>
N₂ +3H₂→ 2NH₃
The moles of H₂ is calculated using the mole ratio
That is from equation above N₂:H₂ is 1 :3
therefore the moles of H₂ = 2.0 moles x (3/1) = 6.0 moles
For starters, ENIAC was as big as a room and had many parts that don't even exist nowadays. It was operated by humans and broke down often. Information processing was a tedious and a difficult process. Modern components enable much faster data travel, fewer opportunities for the thing to break down, and an easier access for people to process data.
<span>In ionic equations, the chemicals are written as the ions which are dissolved in water.
AgNO</span>₃<span>(aq) reacts with K</span>₂<span>SO</span>₄<span>(aq) and produces Ag</span>₂<span>SO</span>₄<span>(s) and KNO</span>₃<span>(aq). The balanced
complete ionic reaction is
2Ag</span>⁺<span>(aq) + NO</span>₃⁻<span>(aq) +2K</span>⁺<span>(aq) + SO</span>₄²⁻<span>(aq) → Ag</span>₂<span>SO</span>₄<span>(s) +2K</span>⁺<span>(aq) + NO</span>₃⁻<span>(aq)
K</span>⁺<span>(aq) and NO</span>₃⁻<span>(aq) present in both sides. Hence, we can cut off them to find net ionic equation.
So, net ionic equation is
2Ag⁺(aq) + SO₄</span>²⁻<span>(aq) → Ag₂SO₄(s)</span>
